Abstract

PURPOSE:To timing-operate an engine at a set time by installing an automatic starter for the set time for a starting motor and a device for confirming the tachogenerator voltage and the operation of a speedometer onto a timing operation controller for an engine. CONSTITUTION:When the start time of an automatic starter is set at a predetermined time for the start of warming operation, and a starting button 9 is turned ON, a controller 1 memorizes the time. When the voltage of a tachogenerator 12 is confirmed (YES signal), and a fine quantity voltage is not confirmed (NO signal) on a speedometer 13, operation is continued for the time memorized in the controller 1, and in the reverse case, the controller 1 is stopped, and the engine operation is stopped. Thus, the engine is timing-operated automatically at a set time, and then the reckless traveling of the automobile can be prevented.

Description

[Detailed description of the invention] "Industrial application field" The present invention relates to an engine warm-up operation device.

"Prior Art" It is common practice to run the engine of a car at llllFm before leaving for work in the early morning. Conventionally, this warm-up operation was carried out by manually starting the vehicle for a few minutes, and then the vehicle was started, so the dispatch time was delayed slightly or it was necessary to get up early and perform the warm-up operation. Therefore, it is conceivable to automatically warm up the engine before the dispatch time, but there is a problem that the warm-up operation may cause the vehicle to run out of control, making it difficult to ensure safety.

``Problems to be Solved by the Invention'' An object of the present invention is to be able to automatically operate the engine for a limited time at a set time, and to prevent the vehicle from running out of control.

"Means for Solving the Problem" In order to achieve the above object, the present invention comprises an engine timed operation control device equipped with an automatic start device at a set time for a starter motor, and the control device operates the starter motor. , the handbrake information signal,
A device that confirms the YES/NO signals of the engine/transmission connection information signal, and further confirms the YES/NO of the tacho generator voltage information signal and the YES/NO signal of the speedometer operation information signal in order to time-limit the engine operation. Warming-up device for an engine comprising: a warm-up device according to the invention, which operates the engine in a timed manner by confirming the NO signal when the key switch is turned on; It is constituted by the warm-up operation device according to the first or second aspect of the invention.

"Operation" Therefore, when the start time of the automatic start device 2 is set to the scheduled start time of warm-up operation and the start button 9 is turned on, the control device 1 memorizes the time. At that time, if the handbrake 10 is opened (No signal) or the connection between the engine and transmission 11 is closed (
The starter 2 does not operate when the handbrake lO is closed (YES signal) and the connection between the engine and the gearshift lit is open (YES signal), and the starter motor operates for 1 to 2 seconds. It starts and drives the engine. However, during this drive, if the voltage of the tachogenerator 12 operated by the engine is confirmed (YES signal), the speedometer 13 does not operate (the vehicle is stopped), and a small amount of voltage is not confirmed on the meter 13 (No signal), the condition is determined. The engine continues to operate for the time (several minutes) stored in the control device 1; in the opposite case, the control device 1 is canceled (released) and the engine is stopped.

Also, the system operates for the above-mentioned time after confirming that the key switch 7 is open (No signal), and if the key switch 7 is turned on before the starting device 2 operates, at that point the control device l starts operating.
The operation of is canceled (cancelled).

In the case of a diesel engine, preheating of the engine is performed, but if preheating is not performed, the operation of the control device is canceled by a No signal), and if preheating is performed, YE
It confirms the S signal and issues a command signal to operate the starter motor.

``Embodiment'' An engine time-limited operation control device 1 is provided in an automobile. This device memorizes the operating time such as 5 minutes, 10 minutes, or 15 minutes, and stops when the time elapses.By pressing the setting button 14, 15 or 16 (Fig. 2) in advance, the above-mentioned operation can be performed. This is for setting the time. This device 1 is also equipped with an automatic start device (starter) 2 at the set time of the starter motor, and the starter motor start time can be set by pressing the incorrect time setting button 17 and pressing the hour setting button 18 and minute setting button 19. This time is stored in the control device I. Then, by pressing the start button 9, the starter 2 operates at the set time and starts the starter motor. The starter 2
The starter motor is driven by turning the key connector 7 ON-OFF. Then, when driving the starter motor, the confirmation device recognizes the open/close (YES/NO) signal in the information signal 3 of the handbrake IO,
ON/OFF information signal 4 of engine/transmission connection section 11
The confirmation device recognizes the ON (No) or OFF (YES) signal of the handbrake IO or engine
After confirming the No signal of either transmission connection section 11, the operation of the control device l is stopped, and both of the above Y signals of 10.11 are confirmed.
After confirming the ES signal, the controller 1 is operated to operate the starter motor. The engine/transmission connection part 11 may be a gear neutral part in a general vehicle, or a torque converter part (parking part) in an automatic vehicle.

When the engine starts operating by starting the starter motor for 1 to 2 seconds as described above, the voltage of the tacho generator 12 increases (YES signal) or does not increase (YES signal).
Information signal 5 (No signal) and speedometer 13
The information signal 6 indicating the generation of a small amount of voltage (YES signal) and non-occurrence (No signal) due to the operation (driving of the car) is received;
The engine continues to operate due to the YES signal from the tachometer generator 12 and the No signal from the speedometer 13, and the N signal from the tachometer generator 12.

The engine is stopped by a signal or a YES signal from the speedometer 13.

If you want to move the car before starting the starter motor after pressing and setting the start button 9, press the key switch 7.
When the control device 1 is turned on (YES signal), the control device 1 is released (middle 11=). If the control device 1 is not in that state, that is, at the set time, the engine can be operated for a limited time by confirming the NO signal of the key switch 7 being turned on.

Of course, in the case of a diesel engine, operation is continued after confirming the YES signal of the engine preheating information signal 8.

20 in the figure is a current time setting button, 21 is a time display section, 22 in FIG. 3 is a tacho generator signal for controlling the operation of the start button 9, and 23 is a power source for the control device I.

``Effects of the Invention'' Since the present invention is configured as described above, it is possible not only to preset the warm-up operation time of the automobile engine to the time immediately before departure in the early morning, and to automatically perform the timed operation at that time. It is possible to obtain a safe automatic warm-up operation device that is free from the risk of a car running out of control due to driving.
