When the vehicle moves forward or backward by itself, the vehicle may be damaged, a vehicle driver, and a pedestrian walking near a rapidly moving vehicle may face a dangerous situation.

Although the cause of such sudden oscillation is not yet clearly and completely identified, it is estimated that the driver's operation error, the aging and defect of the vehicle parts, and the like. In the case of estimating the aging and defects of the vehicle parts, it is estimated that the vehicle suddenly starts due to the aging and failure of the sensors for operating the air and the electronic control unit (ECU) supplied to the engine. Specifically, there may be mentioned aging and failure of intake air temperature sensor (ATS), cooling water temperature sensor (WTS), throttle position sensor (TPS: Throttle Position Sensor), oxygen sensor, and the like. . For example, if the cooling water temperature sensor (WTS) is old or bad, the water temperature is not detected, and the electronic control unit (ECU), which receives the information detected by the sensor, determines that the engine temperature is low and injects a large amount of fuel. It is estimated that the engine speed can be raised to 7000 to 8000 rpm to provide the cause of sudden start.

Therefore, there have been many attempts in the past to prevent such accidents caused by the rapid start of the vehicle, but there are still no clear solutions. Many of the sudden accident prevention devices that have been proposed as solutions are not perfect and are better.

Acceleration and acceleration of the vehicle occurs in a rapid acceleration state, the rapid acceleration state refers to an abnormal value of the engine speed (rpm) according to the type and use of the engine, and usually the rapid acceleration occurs at an abnormal value of at least 4000rpm or more. Accidents caused by such rapid start, according to the drivers experienced directly, claim a sudden acceleration due to the sudden increase in the engine speed (rpm), whether the vehicle is a fault or your own mistakes.

Therefore, in order to prevent the sudden start accident of the vehicle according to the present invention, the current is not supplied by the non-operation of the timer switch installed between the fuel supply line and the starter at a lower engine speed than the set engine speed of the vehicle. By maintaining the same polarity as the permanent magnets faced by the rotating magnets that do not rotate, the accident prevention device is prevented from operating, and at the set engine speed of the vehicle, the rotation after the current is supplied and rotated by the operation of the timer switch. The repulsive force of the magnet operates the permanent magnet of the opposite polarity to the rotating magnet to operate the sudden accident prevention device to cut off the fuel supply of the fuel supply line. In addition, after a certain time after the fuel supply line of the fuel supply line is cut off, the current is not supplied by the operation of the timer switch, so that the rotating magnet reverses the rotation and maintains the same polarity as the permanent magnet to resume the fuel supply.

Next will be described in detail the configuration and operation of the accident prevention apparatus of the vehicle of the present invention.
