Title: Constant speed traveling device for vehicle and car speed control method
Inventor: SHIRAI TAKAO
IPC: B60W10/10
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To suppress deviation between a car speed and a target car speed from increasing in constant speed traveling and suppress the fuel consumption and the noise from deteriorating. SOLUTION: When a throttle is in a fully closed state, whether to downshift or not is determined by whether acceleration a is a downshift determination value, which is set to a smaller value as the car speed deviation ΔV, or the deviation between the car speed V and the target car speed V* becomes larger, or more or not (S102-S122). The use of the downshift determination value can suppress the car speed deviation ΔV from enlarging by quickly downshifting on a steep downslope, and not downshifting in a gentle downslope, if there is some extent of car speed deviation ΔV so that the car speed V can be suppressed from getting smaller than the target car speed V* in a short time with downshifting.
