摘要： PURPOSE:To perform the behavior control of a vehicle controllable in both wheel slip and vehicle behavior by changing the logic of slip control at the time of corresponding to the simultaneously operated case of both controls. CONSTITUTION:The controller of a braking force control system executes ABS control of switching wheel cylinder liquid pressure to three modes-pressure buildup, holding and decompression-by a solenoid valve. The controller determines a solenoid valve driving signal to be set in ABS control and a pressure reducing command by vehicle behavior control according to the respective control rules. In case the pressure reducing command in the latter control is outputted during the former control (steps 301, 306), the controller changes a pressure intensifying command in an ABS control command to a holding command to control the solenoid valve (steps 309-311,). The lateral liquid pressure difference is generated by this change of the pressure intensifying command into the holding command.

摘要： PURPOSE:To prevent ABS control from disturbing vehicle behavior control during control in the case of steering speed being large and display vehicle behavior control performance at the time of requiring turning performance in a vehicle capable of performing both vehicle behavior control and antiskid brake control (ABS). CONSTITUTION:The controller of a braking force control system computes braking liquid pressure difference DELTAP1 to be set by vehicle behavior control and liquid pressure reducing quantity DELTAP2i by ABS control using the respective control rules, and sets (S303, S306) control value DELTAPti applicable to output processing (S307) using each computed value at the operation timing of both controls. At the time of setting, the weight of the former control element (deltaP1iXK) and the latter control element DELTAP2iX(1-K) is changed by a coefficient K corresponding to the steering angle speed ddelta to determine DELTAPti value. The coefficient K is set to be larger as the ddelta is larger, and the controller thereby gives priority to vehicle behavior control in the case of the steering speed being large.

摘要： PURPOSE:To achieve more appropriate integration and control for the braking force control in such a control region that the control of vehicle behavior and the control in the degree of wheel slipping are achieved simultaneously, by preceding the braking force control through the control of slipping degree when both of the control methods are not considered to be achieved simultaneously. CONSTITUTION:While first braking force control is carried out by generating difference in right and left braking forces of wheels to be controlled by a braking force control means B according to the output of a turning condition detection means A, at the time of driving a vehicle, so as to obtain an aimed characteristic of vehicle behavior, second braking force control is also carried out for controlling the braking force so as to define the amount of slip of the wheel in a fixed region based on the output of a physical amount of slip calculation means C. In the region where the first and the second braking force controls are carried out simultaneously, normally, the smaller command value is selected of both of the braking force controls by a command value selection/changing means D, and when the command value to be selected is the one that reverses the right and left difference in the first braking force control, the command value of the second braking force control is preceded as a control command value.

摘要： PURPOSE:To suppress decrease of braking forces as the whole vehicle by providing a setting means by which to set a desired value of hydraulic pressure in such a manner that when vehicle behavior is controlled using a difference between right and left brake hydraulic pressures, wheel cylinder hydraulic pressure is normally controlled to a value smaller than master cylinder hydraulic pressure by a predetermined amount. CONSTITUTION:A brake hydraulic pressure control device has a brake hydraulic pressure control means A capable of controlling right and left brake hydraulic pressures of front and/or rear wheels to cause a difference between the right and left brake hydraulic pressures of wheels to be controlled, according to outputs from a rotating state detecting means B, thereby controlling the brake hydraulic pressures so that vehicle behavior gains a desired characteristic. In this case, a hydraulic pressure desired value setting means C is provided for setting a desired value of hydraulic pressure in such a manner that wheel cylinder hydraulic pressure is normally controlled to a value smaller than master cylinder hydraulic pressure by a predetermined amount so that the intensifying control of brake hydraulic pressure can be performed by the brake hydraulic pressure control means A during control of vehicle behavior. Hydraulic pressure is therefore intensified more than normal wheel cylinder hydraulic pressure when a difference is caused between the right and left brake hydraulic pressures on vehicle behavior control, so that a required difference between hydraulic pressures can be made.

摘要： PURPOSE:To judge whether the vehicle condition is at critical point or not to enable proper control of the rear wheel braking force by setting and controlling a split point corresponding to the lateral acceleration, in the breaking force control in which the rear wheel split point is controlled variably. CONSTITUTION:A fluid pressure control means A with a fluid pressure control mechanism in which a split point can be set variably is provided in a brake fluid pressure system for both the right and left rear wheels. The fluid pressure control means A is controlled so that the split point for the inner wheel side in the turning direction is set smaller than that for the outer wheel side in the turning direction or for the inner wheel side in the turning direction small and for the outer wheel side in the turning direction large, by a split point setting control means C to which the output signals from a lateral acceleration detector means B for detecting the lateral acceleration of a vehicle body id inputted. By this method, the split point can be set corresponding to the lateral acceleration and the vehicle condition can be checked whether it is at the critical point or not to enable the control of the rear wheel brake fluid pressure for each situation.

摘要： PURPOSE:To effectively generate a brake force in an antiskid operation mode, and improve the performance of a brake force control device by controlling a unit load per travel wheel in such a way as to increase the load on a part of wheels undergoing antiskid control. CONSTITUTION:In controlling a brake force on a split road having a different surface mu right and left, a unit load per travel wheel on the lower road surface muis increased, when antiskid control is acting on the aforesaid wheel. For example, when a left front wheel 1L is on the lower road surface mu, a hydraulic active suspension controller 40 raises pressure in the pressure chamber 31 of a hydraulic cylinder 26FL via a pressure control valve 27FL for the left front wheel 1L, and the hydraulic cylinder 26FL is expanded, thereby increasing a force for a body to press the left front wheel 1L to the road surface. When a unit load per travel wheel load increases, a wheel slip decreases and the operation of antiskid control is retarded. Higher brake fluid pressure corresponding to the degree of such retarding can be used and, thereby, stable brake control can be realized, even in the case of braking on the split road.
