    摘要: A target vehicle path is corrected in accordance with the environment surrounding a vehicle during parking assist or U-turn assist. To achieve the target vehicle path, target wheel speeds are set for respective wheels so as to generate a speed difference an inside wheel and an outside wheel of a turn. The target wheel speed is achieved by controlling braking force and driving force of each wheel. Thus, it is possible for the vehicle to turn with a smaller turning radius than that generated by a normal steering angle, and to cause the vehicle to move accurately along the target vehicle path that avoids any obstacles that are present.

    摘要: In a vehicle brake apparatus, front-wheel brake power is controlled with fluid pressure brake power (a front-wheel VB fluid pressure part Fvbf+an increase in fluid pressure brake power equivalent to a liner valve pressure difference ΔP1) and regenerative brake power Freg, while rear-wheel brake power is controlled with only fluid pressure brake power (a rear-wheel VB fluid pressure part Fvbr+an increase in fluid pressure brake power equivalent to a liner valve pressure difference ΔP2), so that regenerative and cooperative brake controlling is executed. When a brake pedal is additionally depressed during front/rear brake power proportion controlling, the shortage of the total brake power is compensated by adding additional brake power Fadd, which is the same as rear-wheel brake power shortage ΔFr generated by the additional depression, to the front-wheel brake power.

    摘要: A vehicular brake control apparatus detects risky occasions and locations that may be risky by using, for example, an infrastructure information input device or a navigation device, and, for such locations and the like, performs the pre-charge so that braking force will be promptly generated. Therefore, the pre-charge can be precisely performed under necessary circumstances, irrespectively of the driver's accelerator operation. Hence, when the driver depresses the brake pedal at such a location or the like, braking force will be promptly generated. Thus, accidents and the like can be prevented.

    摘要: An improved vehicle brake system for controlling the frictional braking force and the regenerative braking force to be applied to a wheel of a vehicle. The brake system reduces the regenerative braking force to a predetermined force and keeps the regenerative braking force at the predetermined force before the start of anti-lock control. When the anti-lock control starts, the brake system decreases the regenerative braking force from the predetermined force. With this arrangement, it is possible to quickly eliminate a locking tendency of any wheel of the vehicle, thereby stabilizing the vehicle.

    摘要: A brake apparatus for a vehicle controls braking force acting on front wheels by hydraulic braking force (front-wheel-side vacuum-booster hydraulic pressure fraction+linear-valve differential pressure fraction), which is frictional braking force, and regenerative braking force, and controls braking force acting on rear wheels by hydraulic braking force (rear-wheel-side vacuum-booster hydraulic pressure fraction) only, to thereby perform regeneration-coordinative brake control. During performance of ABS control, the apparatus sets the limit regenerative braking force to a force under which locking of the front wheels does not occur in a case in which the force acts on the front wheels, which are wheels undergoing regenerative braking, and adjusts the regenerative braking force such that the regenerative braking force does not exceed the limit regenerative braking force.

    摘要: An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.
