Abstract

PURPOSE:To mitigate the hunting frequency by fixing the control duty to the average value immediate before it when detecting a downhill based on the control duty and detecting the vehicle hunting based on the travel vehicle speed. CONSTITUTION:In the duty control type constant-speed travel control, the difference (VM-V) between the memory vehicle speed VM and the travel vehicle speed V is converted into the duty D by the preset control gain G, and a throttle actuator 18 is driven by the control duty D added with the standard duty SD to it to perform the constant-speed travel control of a vehicle. When the vehicle speed hunting occurs on a downhill, the value DM' immediately before a throttle is fully closed at the duty average value DN obtained from the control duty D by the moving average method is stored. The memory value DM' is used in place of the control duty D subsequently. When the acceleration change G is positive and the output Q1 of an FF1 is 1, an FF2 is set.
