ABSTRACT:
A constant-speed cruising control system for a vehicle having an automatic transmission includes a vehicle speed controller which controls the throttle valve of the engine on the basis of the difference between a target vehicle speed and the actual vehicle speed so that the latter approaches the former, a gear shifting mechanism which receives a gear shifting command and shifts the gear stage of the automatic transmission according to the content of the gear shifting command which it receives, and a gear-shifting controller which receives an engine load signal representing the load on the engine and a speed difference signal representing the difference between said target vehicle speed and the actual vehicle speed, and delivers to the gear shifting mechanism a gear shifting command which requires the gear shifting mechanism to shift the gear stage down either when the load on the engine is not lighter than a first preset value or when the load on the engine is lighter than the first preset value and heavier than a second preset value and at the same time the difference between the target vehicle speed and the actual vehicle speed is larger than a preset speed.
