Abstract
A preceding vehicle, an inter-vehicle distance between a self vehicle and the preceding vehicle, vehicle speeds of the self vehicle and the preceding vehicle, an operation of a cruise control, a braking operation, a brake pressure and the like are detected and inputted to a cruise control unit. Based on these input signals, the cruise control system selects a constant speed running mode when the inter-vehicle distance is larger than a specified value and selects a following-behind running mode when the inter-vehicle distance is smaller than the specified value. When the constant speed mode is selected, the vehicle travels at a constant preset vehicle speed by operating a throttle actuator and a brake actuator. Further, when the following-behind running mode is selected, the vehicle travels keeping the inter-vehicle distance at a specified distance by the operation of the throttle actuator and the brake actuator. If the following-behind running mode lasts longer than a specified time, the preset vehicle speed is updated into a vehicle speed higher than an average vehicle speed within the specified time. Further, when a braking operation is detected during the following-behind runnin…
