Abstract
An adaptive cruise control system for an automotive vehicle includes at least a host vehicle speed detector an engine torque control system and a brake control system for controlling at least one of a host vehicle's speed, an inter-vehicle distance, and a relative velocity of the host vehicle to the preceding vehicle. When switching from an engine-torque-control-only operating mode suitable for a relatively small required host vehicle's acceleration/deceleration to an engine-torque-control plus brake-control operating mode suitable for a relatively large required host vehicle's acceleration/deceleration occurs, an initial value of a host vehicle's speed command value is reset to a value being offset from the host vehicle's speed by a predetermined value.
