ABSTRACT:
A cruise control device is provided with a vehicle speed sensor for detecting the actual vehicle speed, and an electronic controller for controlling the opening of the throttle valve based on the detected vehicle speed, to bring the vehicle speed close to a target vehicle speed. The electronic controller serves to obtain a vehicle speed deviation between the target vehicle speed set by a set switch and the actual vehicle speed, select one of a P control mode, a P/D control mode and a fuzzy control mode corresponding to the magnitude of the vehicle speed deviation, and control the opening of the throttle valve. In addition to these functions, the electronic controller may additionally have the function of estimating a change in the vehicle speed provided that the current opening of the throttle valve is maintained, to obtain a correction value for the vehicle speed so that a corrected vehicle speed corrected by the correction value is used to control the opening of the throttle valve. Further, in the case of a vehicle provided with an automatic transmission, a shift diagram applied to a cruise control mode may be prepared in addition to the shift diagram for the automatic transmission itself, so that the electronic controller may have the function of effecting a shifting of the gear ratios of the automatic transmission.
