A preceding-vehicle following control system for a host vehicle is comprised of a road information device () for obtaining road information of a road ahead of the host vehicle, a preceding-vehicle detector () for obtaining preceding-vehicle information of a preceding vehicle ahead of the host vehicle and a controller () connected to the road information device and the preceding vehicle recognizing device. The controller is arranged to determine a road width of the road from the road information, to vary a condition for determining a control characteristic of a control system of a following control for following the preceding vehicle, and to execute the following control on the basis of the condition for determining the control characteristic and the preceding-vehicle information.

Preceding-vehicle following control system

An adaptive cruise control system for a host vehicle is arranged to calculate a target vehicle speed, to calculate a target driving force based on the target vehicle speed, to limit a rate of increase of the target driving force when a direction of a wheel driving torque applied to driving wheels is changed from a decelerating direction to an accelerating direction, and to control a throttle opening of an engine based on the limited target driving force.

Adaptive cruise control system for vehicle

In adaptive cruise control apparatus and method for an automotive vehicle, a velocity of the vehicle is detected, an inter-vehicle distance between the vehicle and a preceding vehicle which is a controlled system of a following run control is detected, a driving force of the vehicle is controlled to maintain the inter-vehicle distance at a target inter-vehicle distance when the inter-vehicle distance between the vehicle and the other vehicle is detected and to maintain the velocity of the vehicle at a set vehicle speed when no other vehicle is detected on the same traffic lane in the forward direction of the vehicle, and an acceleration value at an initial stage of an acceleration is set in such a manner as to be larger than that at a later stage of acceleration when the other vehicle detection state is transferred from the detection state to a non-detection state.
