Abstract: The automatic vehicle braking device is equipped with a braking force control processing portion which, based on the judgment result of a collision judgment processing portion and the judgment result of a steering avoidance judgment processing portion, imparts a turning property in a direction of head-on collision to the vehicle when the lateral position of the obstacle with respect to a travel route curve is large in a condition in which the driver is unconscious of a high possibility of collision between the vehicle and the obstacle and has taken no steering avoidance action yet. As a result, it is possible to reduce the speed of the vehicle and, at the same time, mitigate the damage suffered by the vehicle occupants at the time of collision.

Abstract: The present invention is to enhance safety of a vehicle by avoiding excessive approaches and collisions with preceding vehicles without spoiling a drive feeling of a driver by controlling the vehicle by, for example, initializing CPU and RAM in Step 201, operating a velocity and an acceleration of an own vehicle, following-on ranges from the preceding vehicles, relative velocities, a variable amount of steering angle, the amount of stepping brake from various sensor outputs in Step 202, judging an unconsciousness such as dozing from the variable amount of the steering angle in Step 203, obtaining an approach index expressing degrees of approaching to the preceding vehicles in Step 205, operating a target braking force by the amount of stepping brake pedal and controlled variables corresponding to the approach index based on the following-on ranges or the like when the driver is judged to be dozing in a case of excessively approaching in Step 205, and controlling the own vehicle by outputting these results of

Abstract: In most vehicles, it is necessary to manually operate the parking brake whenever the vehicle is stopped. The manual brake operation is fatiguing and liable to make the driver feel that the operation is troublesome. A controller 10 controls a cut-off valve 8 to close in a vehicle stopping condition, and even if a brake pedal 1 is released, a pressure within a wheel cylinder 6 is held to thereby maintain a braking force. Also, when an accelerator pedal 11 is depressed when the brake hydraulic pressure is maintained within the wheel cylinder 6, the controller 10 controls the cut-off valve 8 in the open condition so that the pressure within the wheel cylinder 6 is reduced to release the brake.

Abstract: To maintain a predetermined distance to each of obstacles ahead of own vehicle, a follow-up cruise control apparatus calculates traveling direction target acceleration and deceleration of own vehicle, and treats, as s safe acceleration and deceleration, the product of the traveling direction target acceleration and deceleration and a weight coefficient determined by a distance between the front obstacle and the center line of the course of own vehicle. The follow-up cruise control apparatus selects a front obstacle having a safe acceleration and deceleration with the highest degree of risk of collision, from among all front obstacles ahead of own vehicle.
