Abstract
A constant-speed running control device is provided, which comprises car speed detecting means for detecting the current car speed of a vehicle, memory means for storing a given car speed, an actuator for controlling a throttle valve, setting means for causing the memory means to store the given car speed, releasing means for releasing the control of the actuator, electronic control means for controlling the actuator in such a direction as to cause the difference between the stored car speed held in the memory means and the current car speed detected by the car speed detecting means to disappear, temperature detecting means, and low-temperature release means for actuating the releasing means in response to the output of the temperature detecting means, whereby the control of the actuator is released through the releasing means when an ambient temperature lowers to thereby prevent erroneous operation and enhance reliability.
