Description

[Detailed Description of the Invention] Purpose of the Invention (Industrial Application Field) The present invention relates to an improvement of a vehicle having a shift lock mechanism, and in particular, when the shift lever is in a shift range position other than the parking range position.
The present invention relates to a vehicle alarm device that uses an alarm to alert the driver when starting the engine.

(Prior Art) Conventionally, in vehicles such as passenger cars, the engine can be started when the shift lever is in the parking range position or the neutral range position. The driver operates the key in that position to start the engine, but in the case of automatic vehicles, when the shift lever is in a driving range position other than the parking range position or neutral range position. Since the driving force of the engine is transmitted to the wheels, if the shift lever is moved to the driving range while the brake lever is in the non-actuating position, where the brakes have not been applied, the vehicle may move slightly due to the creep phenomenon. Yes (for example, Mikoaki
62-20343).

Therefore, when the brake lever is in the non-operating position and the shift lever is in the parking range position, it is impossible to operate the shift lever from this parking range position to a shift range position other than the parking range position. A shift lever lock mechanism is provided, and the shift lever is unlocked only when the brake lever is operated to apply the brakes, thereby avoiding the creep phenomenon caused by erroneous operation such as forgetting to operate the brake.
Efforts are being made to improve driving safety.

(Problems to be Solved by the Invention) However, in the conventional shift lock mechanism described above, when the shift lever is in the neutral range position, it is possible to shift the shift lever to the driving range without operating the brake. Despite the provision of a shift lock mechanism, creep phenomena may occur, resulting in a loss of effectiveness of the shift lock mechanism.

Therefore, the purpose of this invention is to alert the driver with an alarm when starting the engine with the shift lever in a shift range position other than the parking range position (neutral range position), and then It is an object of the present invention to provide a vehicle alarm device that can further improve the effectiveness of a lock mechanism.

Structure of the invention (means for solving problems) As shown in FIG. 1, the vehicle alarm system according to the invention detects that the engine is in a non-operating state in order to achieve the above object. Engine non-operating state detection means A, shift range position detection means B for detecting whether the shift lever is in the parking range position, and key insertion for detecting insertion of a key into the key cylinder as a procedure for starting the engine. The detection outputs of detection means C, engine non-operation state detection means A, shift range position detection means B, and key insertion detection means C are input, and when the engine is in the non-operation state and the shift lever is in a position other than the parking range position, The device is configured to include an alarm generating means D which generates an alarm when the key is placed in the shift range position and the key is inserted into the key cylinder.

(Function) According to the present invention, when the key is inserted into the key cylinder when the engine is in a non-operating state and the shift lever is in a shift range position other than the parking range position, the alarm means D issues an alarm and the shift lever is in a shift range position other than the parking range position. This alerts the driver that the lever is not in the parking range position.

(Example) An example of a vehicle warning device according to the present invention will be described below with reference to the drawings.

and a bottomed cylindrical cap 12 welded and fixed to the tip of the key cylinder housing 11.

The cap 12 is formed with a circular hole 13 through which the tip 10a of the key cylinder 10 faces, and the tip 10a of the key cylinder 10 has a sixth key insertion hole 15 for inserting the key 14 shown in FIG.
It is formed as shown in the figure. The cap 12 corresponds to each position of the key 14, ROCK, ACC,
The words ON and START are engraved on the key 1.
4 is in the ROCK position, the key 14 can be pulled out, and when the key 14 is pulled out from the key cylinder 10, the locking rod (not shown) is directed toward the fitting hole formed in the steering shaft 4. Once the steering wheel 2 was locked, the key 14 was inserted into the key insertion hole 1.
When the key cylinder 10 is inserted into the key cylinder 10 to a predetermined position via the locking rod 5, the locking rod is retracted from the fitting hole of the steering shaft 4 and the steering handle 2 is unlocked.

In this steering lock device, when the key 14 is inserted into the key cylinder 10 and the key is turned toward the ACC side, power can be supplied to accessories such as a car stereo in the ACC position, and when turned to the START position, power can be supplied to accessories such as a car stereo. The engine 16 shown in Figure 2 is started, and after the engine starts, the

The key 14 is returned to the ON position, and there are five key rotation positions from 0 to 4. Between 1 and 4, the key 14 cannot be pulled out and cannot be rotated to either side. Between the rotation position "1" and the rotation position "0", the previous rotation from "1" to "0" cannot be made unless the pushbutton 17 is pressed. This makes it possible to reliably prevent forgetting to lock the steering wheel.

The shift lever 1 is provided in the center console 18 as shown in FIG. 3, and as shown in detail in FIG. The shift lever 1 is a hollow tube, and a rod 21 is provided inside the hollow tube 20. Center console 18

is provided. This day tent plate 23
Regarding the symbols written in , P is the parking range position, R is the reverse range position, N is the neutral range position, D is the drive range position, 2 is the second range position, and L is the drive range position.

The rod 21 is urged upward by a return spring (not shown), and the lower portion of the rod 21 is bent to form a detent pin 24. The detent pin 24 is fitted into an elongated hole 20a formed in the wall of the hollow tube 20 so as to be slidable in the vertical direction, and is constantly engaged with the contour edge 23a by the biasing force of the return spring. The structure is such that The shift lever 1 is provided with a grip portion 25,
A knob button 26 is provided on the grip portion 25, and when the knob button 26 is pressed, the rod 21
is driven downward and the engagement between the detent pin 24 and the contour edge 23a is released, making it possible to shift the shift lever 1 from the neutral range position N to the reverse range position R, for example.

The shift lever 1 is connected to a range select lever 27 of an automatic transmission 22 via a link mechanism,
A position detection sensor 28 is attached to the outer surface of the automatic transmission 22 in correspondence with the shift range position of the shift lever 1. An inhibitor switch is used as the position detection sensor 28. When the shift lever 1 is in the parking range position P or the neutral range position N, the position detection sensor 28 sends a signal to the control circuit 29 to turn on a magnet circuit (not shown) to enable the engine to start. It also functions as a shift range position detection means B for detecting whether the shift lever 1 is in the parking range position P.

The detent plate 23 has a wall portion 23 between the parking range position P and the reverse range position R.
A solenoid 30 is attached to b. This solenoid 30 has a lock rod 31 as shown in FIG. This solenoid 30 is driven when the parking brake lever 32 or foot brake lever 33 shown in FIG. The lock rod 31 projects into the rotation range of the shift lever 1 when the solenoid 30 is not driven. Here, the shift lever 1 is at the parking range position P.
Focusing on the state in which the parking brake lever 32 or the foot brake lever 33 is in the non-operating position where the brake is not applied, the shift lock is engaged even if the engine is started, so shift lever 1 is not shifted to another position. The vehicle cannot be moved to the range position, and sudden advance or retreat when starting the engine is prevented, and the parking brake lever 32, foot brake lever 33, and solenoid 30 are generally in the non-operating position where the brake lever is not engaged. and a shift lever lock mechanism E that locks the shift lever when the shift lever is in the parking range position in order to disable operation of the shift lever to a shift range position other than the parking range position.
It consists of In addition, in Figure 2, 3
4 is a switch for detecting the operation of the parking brake lever, 35 is a switch for detecting the operation of the foot brake lever, and the switch 34 for detecting the operation of the parking brake lever is the switch for detecting the operation of the parking brake lever 3.
When the parking brake lever 2 is in the non-operating position, it comes into contact with the parking brake lever 32 and turns off, and when the parking brake lever 32 is in the operating position, it separates from the parking brake lever 32 and turns on. The foot brake lever operation detection switch 35 comes into contact with the foot brake lever 33 when the foot brake lever 33 is in the non-operating position and turns off, and when the foot brake lever 33 is in the operating position, the foot brake lever operation detection switch 35 contacts the foot brake lever 33 and turns off. The on-state signals of the brake lever operation detection switches 34 and 35, which are turned on when separated from the foot brake lever 33, are input to the control circuit 29. Outputs a solenoid drive signal when one of the ON signals is input. An output signal from an engine rotation sensor 36 that detects the engine rotation speed is input to the control circuit 29, and the engine rotation sensor 36 functions as an engine non-operation state detection means A that detects an engine non-operation state.

The detection signal of the position detection sensor 28 and the detection signal of the engine rotation sensor 36 are input to the control circuit 29 together with the detection signal of a key insertion detection means C, which will be described later. As shown in FIG. 6, the key insertion detection means C is composed of a pair of light emitting element 39 and light receiving element 40.
are disposed opposite to the gap 41 between the cap 12 and the key cylinder 10, as shown in FIG. This light emitting element 39 is always made to emit light by the control circuit 29 regardless of whether the engine is operating or not, and when the key 14 is inserted into the key cylinder 10, the light beam is interrupted. Therefore, the key insertion detection means C functions to detect the insertion of a key into the key cylinder as a procedure for starting the engine. The control circuit 29 outputs a timer drive signal to the timer circuit 42 when the engine is not operating, the shift lever is in a shift range position other than the parking range position, and the key is inserted. For example, it is composed of a monostable multivibrator, which is turned on for a certain period of time to drive a relay 43, which supplies power from a battery 45 to a buzzer 44, causing the buzzer 44 to sound. ing. That is, control circuit 2
9. The buzzer 44, together with the engine rotation sensor 36, position detection sensor 28, and key insertion detection means C, is activated when the engine 16 is not operating, the shift lever 1 is in a shift range position other than the parking range position, and the key 14 is inserted. It serves as an alarm generation means D that sometimes generates an alarm, and thereby, when the engine 16 is not operating and the shift lever 1 is in a shift range position other than the parking range position, the key 14 is placed in the key cylinder 10. At the stage of inserting the shift lever 1, the driver can be warned that the shift lever 1 is not in the parking range position. When the buzzer 44 sounds, the driver operates the brake lever, drives the solenoid 30, retracts the lock rod 31, and immediately moves the shift lever 1 to the parking range position before starting the engine, or Alternatively, the brake lever is operated to start the engine, which further improves the effectiveness of the shift lock mechanism E and further improves safety.

In the above embodiments, the buzzer 44 sounds to give a warning, but the speaker also outputs a voice saying, "Please return the shift lever to the parking position before starting the engine," or "Please return the shift lever to the parking position before starting the engine." It is also possible to warn the driver by emitting a voice that says, "Please operate the engine before starting the engine." Note that the means for giving the driver's attention is not limited to this. In addition, in the example, a pair of light emitting
Although the key insertion detection means C is constituted by the light receiving elements 39 and 40, the present invention is not limited to this. A micro switch is provided in the inner part of the key cylinder housing 11, and key insertion is detected by the contact and separation of the key tips. You can also use it as Furthermore, in the embodiment, the timer 42 is driven by the control circuit 29, but three switches are provided in series, the engine rotation sensor 36, the position detection switch 28,
It is also possible to have a configuration in which each switch is closed based on each detection signal of the key insertion detection means C and the timer 42 is driven.

Effects of the Invention As explained above, the vehicle alarm system according to the present invention, when the engine is not operating and the shift lever is not in the parking range position, inserts the key into the key cylinder, the key to the key cylinder is activated. During the insertion stage, a warning is generated that the shift lever is not in the parking range position, which alerts the driver when starting the engine, thereby further improving the effectiveness of the shift lock mechanism. This has the effect that it is possible to achieve the desired results.

Since a special engine non-operation state detection means is provided, even if it is decided to issue an alarm conditional on key insertion, the shift lever cannot be moved to a position other than the parking range position while the engine is running. This has the effect of not generating an alarm even if the alarm occurs.
