9. A control method for keeping a car at a safe distance in traffic from any other car or an obstacle, comprising steps of:
-
initializing all sensing signals in a sensing device 100 when a main power source of the car is switched on and the accelerating operation is initiated by an accelerator pedal 400 (S20); determining whether a deceleration/braking control unit 300 is switched on, the deceleration/braking control unit being connected with the sensing device 100 and an ECU 200 (S30); projecting long-distance/short-distance optical signals to an obstacle in front of the car so as to sense the obstacle from an external sensor 110 of the sensing device 100 when the deceleration/braking control unit 300 is switched on (S40); calculating an actual distance between the car and the obstacle which is sensed in the sensing step (S40), the calculation being performed by the a calculation unit 220 of the ECU 200 (S50); determining whether the actual distance between the car and the obstacle calculated in the calculation step (S50) is larger than a reference distance value, which is referred to by a lookup table, with reference to the lookup table, which is previously stored in a ROM 260 (S60); operating a guide stop plate 40, so that the guide stop plate 40 moves so as to automatically move the accelerator pedal 400 to its original position, when the actual distance between the car and the obstacle calculated in the distance determination step (S60) is smaller than the reference distance value of the lookup table, the operation of the guide stop plate 40 being caused by a first guide stop unit 315 according to a signal transmitted to the first guide stop unit 315 from a traveling sensing device 130 through the ECU 200 (S70); and operating a brake unit 330 so as to operate a second guide stop unit 350, thereby operating the brake pedal 400′
