Based on foregoing circuit connection relationship, when drive shift moves forward on automobile suspension, preceding radar 200 works, by preceding
Radar 200 identifies the barrier of front side, when automobile head is within 5 meters of barrier, if driver quickly steps on the gas suddenly,
Electronic control unit 400 (changes the anxious acceleration signals that throttle position sensor 100 transmits is received according to throttle position
It is acquired), while the obstacle signal that preceding radar 200 is sent is received again, electronic control unit 400 receives the two at the same time
When signal, will judge driver at this time is accidentally to step on phenomenon of taking throttle as brake, and therefore, electronic control unit 400 presses oil spout when idling
Signal sends fuel injection signal to fuel injector 500, and with idle, car will not dash forward engine;
Similarly, when reverse gear is moved backward on automobile suspension, the rear radar 300 on rear bumper is started to work, and monitors automobile
Rear obstacle is transmitted to throttle position sensor 100 at a distance from vehicle, and by signal, other principles with advance when as,
So it will not be repeated.
To sum up, since this automobile uses long service life, and the reliable throttle position sensor 100 of precision is sensed to feel
Throttle position is surveyed, so that entire automotive system stability and high reliablity, and can prevent driver from accidentally working as throttle constantly
Brake is stepped on.
