ABSTRACT:
A vehicle speed control device for providing constant speed traveling including a main switch circuit for enabling the constant speed traveling, a CPU coupled to the main switch circuit for providing a constant speed traveling control signal, and an actuator for activating a throttle value coupled thereto in response to the control signal output by the CPU. An electromagnetic relay coupled to the actuator inhibits the actuator in response to several signals including a signal from a timer circuit and the timer circuit provides its signal for a time after the start of the engine of the vehicle that is related to a sensed temperature in the engine.
