Abstract:
A preceding vehicle follow-up control system for a vehicle, comprising:a vehicle-to-vehicle distance detector that detects a distance between a controlled vehicle and a preceding vehicle and outputs a signal indicative of the vehicle-to-vehicle distance; a vehicle speed detector that detects a vehicle speed of the controlled vehicle and outputs a signal indicative of the controlled-vehicle speed; an accelerating operation detector that detects whether an accelerating operation based on a driver's demand is executed; and a controller connected to said vehicle-to-vehicle distance detector, said vehicle speed sensor and said accelerating operation detector, said controller being arranged to calculate a target vehicle speed employed for bringing the vehicle-to-vehicle distance closer to a target vehicle-to-distance on the basis of the vehicle-to-vehicle distance and the controlled-vehicle speed, to control the controlled-vehicle speed to bring the controlled-vehicle speed closer to the target vehicle speed, to detect whether the controlled-vehicle speed is greater than a control continuation decision value which is greater than an upper limit of a settable range of a set vehicle speed, to decelerate the controlled-vehicle speed to the set vehicle speed at a rate of a preset deceleration when the controlled-vehicle speed is greater than the control continuation decision value and when the accelerating operation is not executed.
