Abstract

PURPOSE:To prevent unnecessary automatic start by the reservation by a timer by canceling a reservation mode when it is detected that an engine is switched over from stop condition to operation condition at the set start time of the engine. CONSTITUTION:When it is detected by an engine operation detection means 16 that an automobile engine 22 is switched over from stop condition to operation condition after a reservation mode is set by setting a reservation mode storing part 31 with a set switch 13, a controller 14 resets the reservation mode storing part 31 to cancel the reservation mode. Also, when it is detected by the engine operation detection means that the automobile engine is switched over from operation condition to stop condition, or the automatic start of the automobile engine has been completed, further automatic start is stopped. Thus it can be prevented that the engine is automatically started unnecessarily at a set time every day by the reservation by a timer.

As described above, in the automobile engine automatic starter for starting the automobile engine 22 in advance before the passenger gets on the vehicle by timer reservation, the set switch 13 is used.
When the reservation mode is set by, the automobile engine 22 is automatically started at the set starting time.

[0005]

However, once the reservation mode is set by the set switch 13,
Even if the engine 22 is automatically started at the set starting time, the reservation mode is not cleared, and unless reset by the set switch 13, the engine 22 is automatically started at the same time on the next day. As a result, the engine starts unnecessarily and wastefully consumes gasoline.In addition, the engine will not start if there is no fuel if the engine is not released in the reserved mode for many days. The current will continue to flow through the plug, which may cause the battery to run down.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to prevent the engine from unnecessarily automatically starting at the same set time every day by timer reservation. An object of the present invention is to provide an automobile engine automatic starter having improved automatic start reliability.

That is, the continuation of the automatic start of the automobile engine 22 is stopped.

Next, the vehicle air conditioner 40 will be described. The automobile air conditioner 40 shown in the figure is a so-called fully automatic air conditioner 40, and has an auto amplifier 65 for controlling the driving of various doors 46, 54, 59 to 61 attached thereto, and the auto amplifier 65.
Is connected to the controller 14 of the automatic starter 30. Then, the illustrated fully automatic air conditioner 40 is
The automobile engine 22 operates in conjunction with automatic start to pre-air-condition the vehicle interior.

As is well known, the air conditioner 40 for an automobile has an intake unit 41 for selectively taking in the air inside the vehicle or the outside air, a cooler unit 42 for cooling the taken air, and a cabin for heating the air. It has a heater unit 43 that blows out to a predetermined position, and is configured by connecting these.

The intake unit 41 is formed with an inside air introducing port 44 for taking in the air in the vehicle interior and an outside air introducing port 45 for taking in the outside air. An intake door 46 for selectively opening and closing these introducing ports 44, 45 is opened and closed. It is provided freely. In addition, the air taken in is cooled by the cooler unit 42.
A fan 47 driven by a fan motor M is provided for sending to. In the cooler unit 42,
An evaporator 48 in which a refrigerant circulates is built in, and heat exchange between the refrigerant and air is performed to cool the air. This evaporator constitutes a cooling cycle together with a compressor, a condenser, an expansion valve and the like (not shown). The heater unit 43 is provided with a heater core 49 for heating air so as to have a bypass passage 50. Engine cooling water circulates in the heater core 49, and a mix door 54 is provided on the front surface of the heater core 49 so as to be openable and closable. When the mix door 54 is rotated to the full hot position indicated by H in the figure, the maximum heating operation is performed, and when rotated to the full cool position indicated by C in the figure, the maximum cooling operation is performed. Further, when the mix door 54 is rotated to the intermediate position M, the air from the cooler unit 42 passes through the heater core 49 and the bypass passage 50 at a ratio according to the rotating position and is adjusted to a predetermined temperature. .

A mix chamber 55 for mixing warm air and cold air is formed downstream of the heater core 49, and a defrost port 56 is provided to take out air from the mix chamber 55.
A vent port 57 and a foot port 58 are provided. In addition, a defrost door 59, a vent door 60, and a foot door 61 for opening and closing these ports 56, 57, 58.
(These are collectively referred to as "mode doors") are provided so as to be openable and closable.

The air-conditioning mode of the automobile air conditioner 40 includes a vent mode for blowing air toward the upper half of the occupant, a foot mode for blowing air toward the feet, a bi-level mode for performing cold air conditioning with head cold feet, and removal of wind fog. There are various modes such as a diff mode. These air conditioning modes are realized by switching the positions of the mode doors 59 to 61.

The fully automatic air conditioner 40 detects changes in the vehicle interior temperature due to changes in the outside air temperature, the amount of solar radiation, or changes in the occupant with various sensors 70, and keeps the vehicle interior temperature at the set temperature. The blowing air temperature, the blowing air amount, the air suction port, and the blowing port are automatically switched. The auto amplifier 65 includes an intake door actuator 66 that drives the intake door 46, a fan control circuit 67 that adjusts the voltage applied to the fan motor M, a mix door actuator 68 that drives the mix door 54, and mode doors 59 to 61. A mode door actuator 69 for driving is connected. Further, the auto amplifier 65 is connected with sensors 70 for detecting a vehicle interior temperature, an outside air temperature and the like, an A / C switch 71 for operating a compressor of a cooling cycle, and the like. The auto-amplifier 65 controls the actuators 66, 68, 69 and the fan control circuit 67 comprehensively by processing the input signals from the sensors by a built-in microcomputer.

Next, the operation of the automatic starting device 30 for the automobile engine of this embodiment will be described with reference to the main flow shown in FIG.
Description will be given based on each subroutine shown in FIG. 8 and the timing chart shown in FIG. As shown in FIG. 2, the reservation mode is set by setting the reservation mode storage unit 31 by the set switch 13 (step S10, a, e, i, m in FIG. 10), and the controller 14
Checks whether the set start time has elapsed (step 20).

When the subroutine of the set time elapsed check process (step S20) starts, the controller 14 causes the engine operation detecting means 1 to operate as shown in FIG.
By processing the signal indicating the power generation state of the alternator, for example, it is determined whether the automobile engine 22 is switched from the stopped state to the operating state (step S21). When the engine operation detecting means 16 detects that the automobile engine 22 has switched from the stopped state to the operating state, the controller 14 sets the reservation mode storage unit 31 to the reset state and releases the reservation mode (step S23, FIG. 10b). Thus, for example, when the engine 22 is started for engine inspection and the vehicle is moved to a work place such as a maintenance shop while the reservation mode is set, the engine 22 is in the operating state from the stopped state. At the time when it is detected that the reservation mode has been switched to, the controller 14 sets the reservation mode storage unit 31 to the reset state and cancels the reservation mode, and safety is ensured. In this case, since the set time for automatically starting the automobile engine 22 set by the time setting switch 11 is retained in the memory, it is not necessary to re-enter it unless the set time is changed, and the set switch 13 is set again.
You can automatically start at the initial set time just by setting.

On the other hand, as in the case where the automobile engine 22 is manually started (d in FIG. 10) and the reservation mode is set thereafter by the set switch 13 (e in FIG. 10),
When the engine operation detecting means 16 does not detect that the automobile engine 22 has switched from the stopped state to the operating state after the reservation mode is set, the process proceeds to step S22. In step S22, the controller 14 determines whether the set time has passed. If the set time has not elapsed, the process returns to step 21, and the determination in step S21 is always performed until the set time elapses. When it is determined in step S22 that the set time has elapsed, the process returns to the main flow of FIG.
Starts a safety check when starting the automobile engine 22 (step S30).

When the engine starting safety check (step S30) subroutine starts, as shown in FIG. 4, the controller 14 determines whether or not each switch of the switch group 17 such as a door switch is turned on ( Steps S31 to S33) check that the engine condition is good, for example, a signal indicating the power generation state of the alternator (step S34). When all the starting conditions are satisfied, that is, all the doors are closed (S31), the side brakes are set (S32), and the select lever is in the parking position (S33). Also, the engine start signal is output only when the engine is stopped (S34) (step S36), and the process returns to the main flowchart. On the other hand, if even one of the starting conditions in steps S31 to S34 is not satisfied, the process proceeds to step S37, a predetermined engine stop processing operation is performed, and the reservation mode is released.

If all of the starting conditions are satisfied, the controller 14 starts engine-on control (step S40). This engine on control (step S
When the subroutine 40) is started, the controller 14 operates the engine starter 26 by turning on the start relay and the ignition relay of the engine starting circuit, as shown in FIG.
2 is started (step S41, g in FIG. 10). If it is determined in step S42 that the automobile engine 22 has started from the power generation state of the alternator, the controller is the same as in the case where it is detected in step S21 of FIG. 3 that the automobile engine 22 has switched from the stopped state to the operating state. 14 resets the reservation mode storage unit 31 to cancel the reservation mode (step S43). In this case, the reservation mode is released, but the automatic start continuation mode storage unit 32 remains in the set state and the automobile engine 22
The automatic start of is continued. That is, the flow of the series of operations shown in FIG. 2 continues. Then, the timer 15 built in the controller 14 is started (step S4
4) Return to the main flow chart. On the other hand, step S
When it is determined that the engine start has failed in 42, the process returns to the main flow of FIG. 2 and the engine start from the engine start safety check (step S30) is performed up to twice (steps S45 and S46), 3 If it fails more than once, the routine proceeds to step S47, where a predetermined engine stop processing operation is performed and the reservation mode is canceled.

When the automobile engine 22 is started,
The controller 14 starts the automatic air conditioner control and the engine continuation control (step S50). When the subroutine of the automatic air conditioner control and the engine continuation control (step S50) starts, the controller 14 turns on the A / C switch 71 to operate the fully automatic air conditioner 40 (step S51), as shown in FIG.
In step S52, the vehicle interior temperature detected by the sensors 70 is compared with the target set temperature, and when the vehicle interior temperature is not within a predetermined allowable range with respect to the target set temperature, that is, rapid cooling and heating air conditioning operation is performed. If necessary, the process proceeds to step S53. In step S53, the auto amplifier 65 sets the optimum air-conditioning mode, the intake mode, the fan rotation speed, and the like that can quickly reach the target set temperature, and performs the rapid temperature setting process. When it is determined in step S52 that the vehicle interior temperature is within the predetermined allowable range with respect to the target set temperature, the process proceeds to step S56, the mode is changed to the normal auto air conditioner control mode, and the auto amplifier 65 has the built-in micro A computer processes the input signals from the switches and the sensor group, and each actuator 66,
68, 69 and the fan control circuit 67 are comprehensively controlled so that the temperature of the blown air (the rotation control of the mix door 54) and the amount of the blown air (the voltage applied to the fan motor M are controlled so that the vehicle interior temperature becomes the target set temperature. Control), switching between the air suction port and the air outlet (intake door 46, mode doors 59 to 6)
(1 rotation control) is automatically performed.

While the vehicle air conditioner 40 is operating, that is, while the engine is operating, the fail-safe check (step S54) is always performed. When the fail-safe check (step S54) subroutine is started, as shown in FIG. 7, the controller 14 determines whether or not each switch of the switch group 17 such as a door switch is turned on (steps S71 to S71).
73), the engine state is good, for example, a signal indicating the power generation state of the alternator is checked (step S74). Then, if any one of the conditions of steps S71 to S74 in the fail-safe check (step S54) is not satisfied, the process proceeds to step S75, and a predetermined engine stop processing operation is performed.

When all the fail-safe conditions are satisfied, the original automatic air conditioner control and the engine continuation control are returned to and the process proceeds to the next step S55. Continue the pre-cooling operation (steps S52, S53, S56, S5
4, S55), when the timer 15 counts t1 seconds from the start of the engine 22 (step S55), the original main flow is returned to, and the process proceeds to step S60. In this step S60, as shown in FIG. 8, the controller 14 sets the automatic start continuation mode storage unit 32 to the reset state and outputs an engine off signal (step S61), and a predetermined engine stop processing operation is performed (step S62, FIG. 10
H). Preliminary cooling and heating operations will also be stopped accordingly. The time t1 from the start of the automobile engine to the stop thereof is set to an arbitrary time of about 10 to 20 minutes at which warm-up and the like ends. Further, in the present embodiment, when the automobile engine 22 is automatically started (j, n in FIG. 10), the reservation mode is canceled at that time, but if the set switch 13 is pressed again during the automatic start, the reservation mode is stored. The part 31 is set and the next reservation mode can be set (k, o in FIG. 10). After that, the automatic start is continued for a predetermined time and a predetermined engine stop process is performed (l in FIG. 10), but if the set switch 13 is pressed again before the stop, the reservation mode storage unit 31 is reset and the reservation mode is set. At the same time, the automatic start continuation mode storage unit 32 is reset to stop the automatic start of the automobile engine 22 (p in FIG. 10).

As described above, in the automatic starting apparatus for the automobile engine of this embodiment, after the reservation mode is set by setting the reservation mode storage section 31 by the set switch 13, the automobile engine is stopped by the engine operation detecting means. When it is detected that the state is switched to the operating state, the controller 14 determines that the reservation mode storage unit 3
When the reservation mode is released by setting 1 as the reset state and the engine operation detecting means detects that the automobile engine has switched from the operating state to the stopped state, or when the automatic start of the automobile engine ends, Since the continuation of the start is stopped, the timer reservation can prevent the engine from being automatically started at the same set time every day unnecessarily. As a result, it is possible to wastefully consume gasoline, or even if unnecessary automatic engine start continues for days and runs out of fuel, current may continue to flow to the spark plug and the battery may run out. Disappear. Further, the reservation mode can be set even while the engine is operating, and the reservation mode will not be canceled even if the engine is subsequently stopped.

Further, in this embodiment, whether the engine 22 is automatically started according to the reservation mode or is normally started, when the engine 22 is switched from the stopped state to the operating state, Since the controller 14 decides to cancel the reservation mode by setting the reservation mode storage unit 31 in the reset state, for example, the engine 2 for the engine inspection while the reservation mode is set is kept.
When it is detected that the engine 22 is switched from the stopped state to the operating state when the vehicle is moved to a work place such as a maintenance factory when the vehicle 2 is started, the controller 14 resets the reservation mode storage unit 31. The reservation mode is released. As a result, when the engine is inspected by opening the bonnet, it is possible to easily and reliably avoid the situation where the engine suddenly starts automatically at the set start time, and safety is assured. Since it can be implemented with a circuit configuration, the cost can be reduced as compared with installing an expensive bonnet switch.

Further, in the present embodiment, the controller 14 stores the reservation mode storage section 31 for storing the set or reset of the reservation mode for automatically starting the automobile engine 22 at the set starting time, and the automobile engine 22.
Has an automatic start continuation mode storage unit 32 for storing a set or reset of an automatic start continuation mode for continuing the automatic start after being automatically started, and canceling the reservation mode and stopping the automatic start continuation separately. Therefore, by pressing the set switch 13 again during the automatic start after the reservation mode is canceled, the next reservation mode is set while continuing the automatic start as it is, or by pressing the set switch 13 again, the automobile engine Two
It is possible to stop the continuation of the automatic start of 2 and to cancel the setting of the reservation mode and the continuous stop of the automatic start,
It is possible to control each independently.

[0029]

As described above, the automatic engine starting apparatus for an automobile engine according to the present invention operates in an engine for detecting that the automobile engine is switched from a stopped state to an operating state or from an operating state to a stopped state. When the engine operation detecting means detects that the automobile engine has switched from the stopped state to the operating state at the set start time after setting the reservation mode with the set switch and setting the reservation mode by the set switch. Cancels the reservation mode and stops the automatic start when the engine operation detecting means detects that the engine has switched from the operating state to the stopped state, or when the automatic start of the vehicle engine ends. As a result, the timer is automatically scheduled to run automatically at the same set time every day. It is possible to prevent the movement. As a result, it is possible to wastefully consume gasoline, or even if unnecessary automatic engine start continues for days and runs out of fuel, current may continue to flow to the spark plug and the battery may run out. Has the effect of disappearing. Further, the reservation mode can be set even while the engine is operating, and the reservation mode will not be canceled even if the engine is subsequently stopped.

Further, since the reservation mode is canceled and the automatic start continuation is stopped separately, by pushing the set switch again during the automatic start after the reservation mode is canceled, the automatic start is continued as it is. The reservation mode can be set or the automatic start of the automobile engine can be stopped by pressing the set switch again.The reservation mode setting cancellation and automatic start continuation stop can be controlled independently. It becomes possible to do.
