Abstract
An automatic car-speed controller is provided with a car-speed sensor, a command switch, a car-speed memory, an actuator, a control mechanism, and a holding circuit for cutting off an electric current to the actuator according to a braking operation and maintaining the actuator in its nonworking state till the actuator returns to its working state in response to a cruise command signal from the command switch in addition to the control mechanism. According to this controller, it is possible to release the actuator rapidly from the automatic car-speed controlling state in response to the braking operation even if the trouble occurs in the control mechanism.
