PURPOSE:To enable smooth starting in conformity with a driver's intention by automatically operating a control device of a car and by enabling to release damping by stepping of an accelerator in case that a shift lever is shift-operated to a running range under the predetermined conditions. CONSTITUTION:The captioned device has each detecting element S1-S4 of a running range, engine rotation number, car speed and an accelerator opening, and these output signals are inputted to a control unit 3. And when it is shifted to the running range, car speed is zero, engine rotation number is more than 1,000rpm and accelerator opening is zero, a valve body 24 is opened by magnetizing solenoid 23 of an electromagnetic switch valve 2b, intake negative pressure is introduced to a negative pressure chamber 21 of an actuator body 2a and a diaphragm 27 is moved to the left. Thus, a brake pedal 4 is oscillated in a stepping direction through an operation rod 28, a bell crank 6 and an operation cable 60, and a brake 1 is operated and damping force is obtained. Said solenoid 40 is de-magnetized at the time of stepping of an accelerator pedal. |
