Cruise and parking control device in automobile

Abstract

Abstract PURPOSE:To prevent the vehicle from incurring a creep, etc. and as well to prevent the vehicle from moving backward upon starting on a slopping road, by utilizing a throttle valve opening degree control actuator in a cruis control device, also for automatic brake hold upon parking. CONSTITUTION:When a main switch S is turned on upon running, a CPU1 initiates operation so that a compartor 8 compares an actual vehicle speed signal (b) with a reference vehicle speed (c). In accordance with the result of the comparison, an output signal (d) is delivered through a switch unit 3 to automatically control the opening degree of a throttle valve. When the speed of a vehicle comes to zero by depressing a brake pedal, the CPU1 changes over the switch unit 3 onto the decelerator 5 side. Simultaneously, the reference vehicle speed signal (c) is turned into zero so that the actuator 2 automaically controls a brake operating mechanism to make the actual vehicle speed zero, and therefore, braking force may be held even if the brake pedal is released.
