摘要： PROBLEM TO BE SOLVED: To provide a braking-force control device capable of properly exhibiting braking capacity of a wheel.SOLUTION: Braking force of the respective wheels of a vehicle can be controlled. The braking force of the first wheel being a wheel relatively large in a slip amount out of a pair of right-left wheels (S1 YES), is kept from increasing (S3), and the breaking force of the second wheel being a wheel relatively small in the slip amount is increased. The increase in the braking force of the first wheel may be restrained before a friction coefficient of a road surface to the first wheel reaches the peak and when the friction coefficient is the vicinity of the peak (S2 YES).

摘要： PROBLEM TO BE SOLVED: To provide a behavior control device for a vehicle capable of preventing the vehicle from rollover effectively as much as practicable, while the vehicle is also prevented from becoming unstable, for example vibrating in rolling and/or pitching. SOLUTION: The behavior control device of the vehicle works so that; when judgement is passed that the operation is in an emergency avoid steering condition (S20), the target slip ratio Srfo of the front wheel located outside about cornering is set to the preset high value (S70), and the braking force to the front wheel outside is controlled on the basis of a higher target slip ratio Srfo than in the spin control in the situation with a higher friction coefficient μ of the road surface (S80-150), and when the operation is at starting the wheel braking force control in the emergency avoid steering condition, the duty ratio Dri corresponding to the slip ratio deviation ΔSri of the front wheel outside is computed from a usual map (S130 and 132). When the operation is after starting the wheel braking force control in the emergency avoid steering condition, the duty ratio Dri is computed from a map in which the incremental/decremental gradient of the braking pressure is limited (S130 and 134).

摘要： PROBLEM TO BE SOLVED: To provide a vehicle behavior control device which can effectively suppress occurrence of roll vibration by simple control.
SOLUTION: A vehicle behavior control device 1 determines existence of occurrence of roll vibration in vehicle based on a roll angle, a yaw angle, lateral force, and vertical displacement of the vehicle, and when occurrence of the roll vibration is detected, the lateral force Fout of an outer ring is decreased rather than the lateral force Fin of an inner ring. Thereby, since the lateral direction μ of the vehicle and a road surface decreases and sideslip of vehicle arises, and roll vibration is suppressed effectively, kinetic energies of vertical direction generated at the outer ring side of the vehicle at roll vibration time becomes possible to convert into the kinetic energies in the direction of vehicle shifting to the turning outer side. In controlling lateral force, complication of a control means can be avoided, while securing high responsiveness by using braking pressure control of each wheel by a VSC controller 10 of increasing prevalence rate.

摘要翻译：要解决的问题：提供一种能够通过简单的控制有效地抑制滚动振动的发生的车辆行为控制装置。解决方案：车辆行为控制装置1基于车辆的侧倾角，偏航角，横向力和垂直位移来确定车辆中的滚动振动的发生的存在，并且当检测到发生滚动振动时，外圈的横向力Fout减小而不是内圈的横向力F Fin。因此，由于车辆的横向方向μ和路面减小，车辆出现侧滑，并且有效地抑制了侧倾振动，因此可以在滚动振动时刻在车辆外圈侧产生的垂直方向的动能转换进入车辆向转向外侧移动的方向上的动能。在控制横向力时，可以通过使VSC控制器10的每个车轮的制动压力控制以更高的流行率来确保高响应性，从而避免了控制装置的复杂化。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enhance the comfortableness of a vehicle equipped with a braking system including a hydraulically controlled driving system.
SOLUTION: ECU 100 of this vehicle 10 starts the vehicle speed maintaining control using a brake actuator 200 when the prescribed executing conditions are met. During the vehicle speed maintaining control, an incremental/decremental control is made for the target differential pressure Pt of a differential valve 205 in the brake actuator 200 on the basis of the result from comparing the vehicle speed with its target value. The target differential pressure Pt corresponds to the braking pressure for applying brakes to the vehicle 10, as a result, taking a value in accordance with the gradient of the slope on which the vehicle 10 is going to run down. Accordingly if the condition continues in which the target differential pressure Pt lies below the reference differential pressure Pend, the ECU 100 ends the vehicle speed maintaining control upon judging that the vehicle speed maintaining control can be ended safety, as the slope not having the degree such as to require the vehicle speed maintaining control.

摘要： PROBLEM TO BE SOLVED: To establish a compatibility between the stability of a vehicle and its comfortableness when the vehicle runs down a slope while maintaining the vehicle speed.
SOLUTION: The vehicle 10 has an ECU 100 which executes a braking control processing. The braking control processing executes two routines independently of each other, one which is to maintain the vehicle speed to the target value or below on the basis of the mean of the wheel speeds and the other which disengages locking of one wheel on the basis of the difference between the wheel speeds. The routine to maintain the vehicle speed to the target value or below works in a pressure boosting mode to control the braking forces of the wheels in a lump in accordance with the target differential pressure of a differential pressure valve 205. On the other hand, the routine to avoid locking works in a decompression mode to decompress the braking force given to that wheel which has a relatively lower wheel speed only in case the difference between the wheel speeds has exceeded the lock judging value Vdiff at the time of maintaining the vehicle speed as described. Therein if the difference between the wheel speeds lies at or below the lock judging value Vdiff, the wheel cylinder pressure is decompressed in the routine for maintaining the speed, and locking is disengaged.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for controlling a braking force of a vehicle, which can precisely control the braking force even when a vehicle speed is low, and further to provide an apparatus for monitoring the reversing state of the vehicle.
SOLUTION: The apparatus for controlling the braking force of the vehicle detects a time period from the time that the braking force of the braking apparatus has been released up to the time that the vehicle speed in the reverse direction in a sloping way has reached a specified speed, and determines a braking output according to the detected time period, and controls the braking force according to the determined braking output. The time period depends upon the gradient of the sloping way. Therefore, when the braking output is determined according to such a time period, the control of the braking force according to the gradient of the sloping way is possible even in the very low-speed range in which the vehicle speed cannot be detected.
