STEADY DRIVING SPEED CONTROL DEVICE AND ITS METHOD OF A CAR

摘要

It is installed around the driver's seat, the operation switch SW1 turned on by the driver, the brake switch SW2 that detects when the brake pedal is stepped and outputs it as an electrical signal, and detects when the accelerator pedal is stepped on. The accelerator pedal switch SW3 output as an electrical signal and the constant speed driving operation are performed when the operation switch is turned on, and the brake switch or the pedal switch is turned on while the operation switch is not turned on or during the constant speed driving. In this case, the control unit 10 outputs a control signal for releasing the constant speed driving operation, a driving unit 20 for generating and outputting a solenoid driving signal according to the control signal input from the control unit, and the input from the driving unit. Solenoid stopper 30 to operate the stopper according to the solenoid drive signal, and the accelerator pedal It is interlocked, and comprises a locking bar 40 which is stopped by the solenoid stopper, and an elastic member 42 to provide a restoring force so that the locking bar can be returned to its original position, using an acceleration pedal using a locking bar Very simple structure by intermittent, fast response by designing control circuit using digital circuit;Provided is a cruise control apparatus for a vehicle having a speed and a method thereof.
