CONSTANT-SPEED TRAVEL DEVICE FOR VEHICLE

摘要

PURPOSE:To suppress the fluctuation of the vehicle speed when storing it or immediately after it by detecting the time when the target vehicle speed value is stored or the fixed time immediately after it and correcting the speed change ratio immediately before storing it to the target speed change ratio in this fixed time. CONSTITUTION:A constant-speed travel control device 100 drives a throttle actuator 140 and controls a throttle valve 150 based on various input signals. A continuously variable transmission (CVT) control device 200 drives a governor actuator 240 and a speed change oil pressure actuator 241 and controls a CVT 250 based on various input signals. A constant-speed travel control performance detecting means 107 is provided on the constant-speed travel control device 100. A correcting means 204 is provided on the CVT control device 200. If the time when the target vehicle speed value is stored or the fixed time immediately after it is detected by the means 107, the speed change ratio immediately before it is corrected to the target speed change ratio in this fixed time.
