摘要： When a vehicle-to-vehicle time gap is changed from a first level to a second level with a selector switch, a controller determines a desired time gap so that the desired time gap varies from the first level to the second level at such a gradual rate as to prevent an abrupt change in the vehicle speed. The controller further determines a desired vehicle spacing from the controlled vehicle to a preceding vehicle in accordance with the desired time gap and a sensed vehicle speed, and controls the driving force and braking force of the controlled vehicle so as to bring the actual vehicle spacing closer to the desired vehicle spacing.

摘要： A preceding-vehicle follow-up control system is arranged to calculate a target vehicle speed based on a vehicle-to-vehicle distance and a controlled-vehicle speed, to calculate a target acceleration based on the target vehicle speed and to control driving force and braking force of the controlled vehicle based on the target acceleration. During this control period, the target acceleration is limited by an acceleration limit and a deceleration limit which are varied according the controlled-vehicle speed, respectively. This arrangement enables a follow-up vehicle speed control to be preferably executed without applying a strange feeling to a driver.

摘要： A preceding-vehicle follow-up control system is arranged to calculate a target vehicle speed employed for bringing a detected vehicle-to-vehicle distance closer to a target vehicle-to-distance, to control the controlled-vehicle speed to bring a controlled-vehicle speed closer to the target vehicle speed, to decelerate the controlled-vehicle speed to a set vehicle speed at a rate of a preset deceleration when the controlled-vehicle speed is greater than a control continuation decision value greater than an upper limit of the set vehicle speed and when the accelerating operation is terminated. This arrangement provides a smooth drive feeing to a driver even after an acceleration of the controlled vehicle is executed during a follow-up control and is terminated.

摘要： A controller (5) controls the engaging force between a pump impeller (1a) connected to an engine (2) and a turbine runner (1b) connected to an automatic transmission (23). The controller (5) first performs feedforward control of the engaging force. The controller (5) determines a reference value and a target rotation speed based on the capacity characteristics of the torque converter (1), and if the rotation speed of the engine (2) becomes less than the reference value, performs feedback control of the engaging force so that the deviation between the target rotation speed and the rotation speed decreases. When a predetermined condition is satisfied, the controller (5) changes over from feedforward control to feedback control, even if the rotation speed of the engine (21) is not less than the reference value. As a result, the control precision of feedback control when performing a slip lock-up, is increased.

摘要： In an antiskid braking system for increasing or decreasing a braking force according to a wheel speed and a vehicle speed, an algorithm applied to the determination of a braking force decrease amount is improved. Once a target braking force decrease amount is determined according to the wheel speed and vehicle speed, this is compared with a predetermined minimum decrease amount, and when the target decrease amount is less than the minimum decrease amount, braking force is decreased according to the minimum decrease amount. The minimum decrease amount is preferably determined according to the braking force immediately before the braking force decrease. In this way, braking force reduction insufficiencies in several conditions are prevented.

摘要： In a vehicle driving force control apparatus for controlling a driving force of the vehicle to achieve a target acceleration or a target vehicle speed, a running resistance estimating section calculates an estimated running resistance. A target acceleration modifying section modifies the target acceleration with the estimated running resistance and thereby decreases the target acceleration with increase in the estimated running resistance.
