EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a block diagram of a system for preventing the reverse of a vehicle according to the present invention, and reference numeral 1 denotes a brake pedal.

The brake pedal 1 is to allow the brake to be selectively operated when the speed of the driving vehicle is decelerated or stopped, so that the brake is not reversed by the inclination angle or the dead weight of the lodge. An operating means for selectively controlling the return operation is arranged in front of the brake pedal 1.

The above-mentioned operating means includes a motor 3 which is selectively supplied with a battery power source B + and is rotated forward and backward, and is provided to the motor 3 shaft, as well as a cam located in the operating area of the brake pedal 1. (5) and the left turn electrical switch (7) having a left turn stop function and the right turn electrical switch (9) having a right turn stop function as selectively turned on and off by the cam (5) of the motor (3). By selectively applying the battery power (B +), the motor 3 is rotated forward and reverse to selectively control the return operation of the brake pedal (1) to perform the braking operation by the cam (5). .

The left turn electrical switch 7 is to be powered by the acceleration-sensing electric switch 13 that is turned on, off in accordance with the operation of the accelerator pedal 11, the acceleration-sensing electric switch 13 is The battery power source B + is selectively applied by the on / off operation of the first-shift-sensing type electric switch 15 that is turned on or off during the first shift by gear shifting, thereby controlling the operating state of the motor 3. I'm trying to.

The one-stage shift sensing type electric switch 15 is installed on the transmission case 17 and is turned on and off by a ball 23 seated in the groove 21 formed in the first and second speed shift rails 19. As described above, when the first and second speed shift rails 19 are transported by the operation of a shift lever (not shown) and the ball 23 is seated in the groove 21, the switch is kept in an on state.

Each of the switches 7, 9, 13, and 15 described above has a switch structure for turning on and off by a push type, and as shown in FIG. (25) (27), a connection terminal 29 for selectively connecting these terminals (25) and (27), and a plunger (33) provided with a ball shot with a spring (31), and a linear transfer displacement by contact. It consists of a push rod 35 for conveying the plunger 33 by, each terminal 25, 27 is selectively connected by the connection terminal 29 in accordance with the operation of the push rod 35 Battery power (B +) is to be applied.

On the other hand, the right-turn electric switch 9 is electrically connected to the inclination-sensing type electric switch 37 that is selectively turned on and off by the inclination angle of the vehicle, that is, the angle inclined from the front side to the rear side, so that the battery power source B + The inclined sensing type electric switch 37 is rotatably installed on the hanger 39 as well as being installed with a spring 41 and is provided with a connection terminal 43 on one side thereof. The weight 45 and the respective terminals 47 and 49 which allow the battery power B + to be applied by the swinging operation of the center weight 45 are caused by the inclination angle of the vehicle. It is adapted to be selectively applied to the left turn electrical switch 9.

In addition, the inclination-sensing type electric switch 37 is a vehicle speed sensor 53 for detecting the speed of the vehicle according to the operation of the ignition switch 51 for connecting the battery power (B +) and the signal of the speedometer 55 The battery power source B + is electrically connected to the speed-sensitive electric switch 59 that is selectively turned on and off according to the electrical output signal of the electronic control unit 57 that compares with the input memory value. It is supposed to be.

That is, the speed sensitive electric switch 59 can be lifted and lowered by the magnetization force of the electromagnetic coil 61 and the electromagnetic coil 61 selectively magnetized by the electrical output signal of the electronic control unit 57. And each terminal for connecting the battery power source B + by the plunger 65, which is provided with a spring 63, and the connecting terminal 67 provided to the plunger 65 and the connecting terminal 67. 69) (71).

When the vehicle reverse prevention system of the present invention configured as described above maintains the state in which the vehicle is stopped on the incline while driving, that is, the shift stage is maintained in a neutral state and the input signals of the vehicle speed sensor 53 and the speedometer 55 are Is satisfied, the electronic control unit 57 outputs an electrical output signal to the electromagnetic coil 61 of the speed sensitive electric switch 59.

Therefore, as the electromagnetic coil 61 is magnetized, the plunger 65 rises to overcome the elastic force of the spring 63 so that each terminal 69 and 71 are energized by the connection terminal 67 so as to be speed sensitive. The electrical switch 59 is turned ON.

Therefore, the battery power source B + is applied to the inclination sensing electrical switch 37 through the ignition switch 51 and the speed sensitive electrical switch 59, and the inclination sensing electrical switch 37 is the inclination angle of the vehicle. As the central weight 45 overcomes the elastic force of the spring 41 and is inclined from the hanger 39, the respective terminals 45 and 47 are energized by the connection terminal 43 provided on one side thereof, and the brakes are energized. The battery power source B + is applied to the right turn electrical switch 9 of the operating means for controlling the pedal 1.

Accordingly, since the right turn electric switch 9 is ON, the battery 5 is applied to the motor 3 and is turned right so that the cam 5 is shown in solid line in the state shown by a dashed-dotted line. As described above, by supporting the brake pedal 1 and turning off the right-turn electric switch 9, the operation of the motor 3 is stopped.

In such a state, if the user presses the clutch pedal (not shown) to start the ramp and shifts the shift stage to the first stage via the shift lever, the first shift sensing type electric switch 15 provided to the transmission case 17 is turned on. The switch 15 has a ball 23 seated in the groove 21 formed in the first and second speed shift rails 19, so that the plunger 33 is lowered by the elastic force of the spring 31. Each of the terminals 25 and 27 is energized by the connecting terminal 29.

In this state, when the foot is released from the brake pedal 1 and the accelerator pedal 11 is pressed down, the brake pedal 1 is not returned because the cam 5 provided on the shaft of the motor 3 supports the brake. Preservation of the state prevents the reversal of backward movement and at the same time increases the engine speed.

At this time, when the rotational speed of the engine is 1500 to 2000 RPM, that is, the state as shown by the dashed-dotted line in FIG. 1, the push rod 35 of the acceleration sensing type electric switch 13 in contact with the accelerator pedal 11. Is interlocked together by the elastic force of the elastic member 31 so that each terminal 25, 27 is energized by the connecting terminal 29 to maintain the ON state. It is applied to the left turn electrical switch (7) via the shift-sensitive electrical switch (15) and the acceleration-sensitive electrical switch (13).

Therefore, since the left turn electrical switch 7 is ON, the battery power source B + is applied to the motor 3 and rotates left, whereby the cam 5 supporting the brake pedal 1 is in a solid line. As shown by the dashed-dotted line in the state shown, the operation of the motor 3 is stopped as the left-turn electric switch 7 is turned off by the cam 5.

As a result, the rotation speed of the engine is increased and the brake pedal 1 is returned, whereby the backward driving of the vehicle starting at the inclination is prevented from being pushed back, and a good start is achieved.

Is driven and supported by the cam, and the vehicle is pushed back on the ramp because the brake pedal is not returned until the engine speed reaches a predetermined speed when the accelerator pedal is operated with the first gearshift for starting. Not only can the phenomenon be prevented in advance, and the collision with the rear vehicle can be prevented, and even the novice driver can easily expect the start of the ramp, and there is an advantage that the starting is not stopped.
