ABSTRACT:
A constant-speed regulating device for a vehicle comprising: a control circuit which receives information regarding the running velocity of the vehicle and produces an output signal as a result of calculations in which said information and control constants are used; a drive circuit which receives the output signal and produces an drive signal; and an actuator for opening and closing the throttle valve of the vehicle. The actuator is driven in accordance with the drive signal. The actuator comprises a stepping motor. The control circuit receives data regarding the type of the vehicle, the state of the engine, and the gear position, and comprises: a first memory means for storing the rotation angle of the stepping motor which is within or beyond one revolution; a means for modifying at least one of the control constants; and a second memory means for storing said control constants even when the main power is turned off. The modifying means modifies at least one of the control units in accordance with one or more items of the data.
