Abstract: PURPOSE:To prevent a torque steer phenomenon by controlling solenoid valves between a control valve and a power cylinder so as to squeeze their valve opening areas based on a signal from a control circuit when a vehicle is quickly accelerated. CONSTITUTION:Solenoid valves 20, 21 controlling the valve opening areas in response to the currents fed to their coils are incorporated in fluid feed/ discharge paths 18, 19 between a control valve 3 and a power cylinder 17, and an acceleration meter 40 outputting a signal in response to the acceleration of a vehicle and a control circuit 30 inputting the signal are provided. When the vehicle is quickly accelerated, the solenoid valves 20, 21 are controlled so as to squeeze their valve opening areas based on the signal from the control circuit 30. As a result, the fluid flow between the control valve 3 and the power cylinder 17 is suppressed, and the assist force for the steering operation is reduced. Accordingly, the steering sustaining function is improved, and a torque steer phenomenon can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent brake fluid pressure control from becoming unstable due to a delay in response by feedback control caused by periodical error components resulting from localized wear or the like on the surface of a brake rotor. SOLUTION: Target wheel cylinder pressure Pwt is computed based on pressure Pm in a master cylinder 40 and a pedaling stroke St (S150, 200). The deviation ΔPw of the target wheel cylinder pressure Pwt from actual wheel cylinder pressure Pw is computed (S250). Based on the deviation ΔPw, a correction value Pva is computed on each of the rotational angle θ of a wheel for every increase in a minute rotational angle Δθ (S300). In the case of high vehicle speed, the deviation ΔPw is corrected with the correction value Pva (S700, 750) and, based on the deviation ΔPw after the correction, the feedback control amount Pfb of the wheel cylinder pressure is computed (S800), and the wheel cylinder pressure Pw is controlled based on the feedback control amount Pfb (S850).

Abstract: PROBLEM TO BE SOLVED: To surely prevent the braking force of the wheel opposing to a fallen wheel in the cross direction of a vehicle from becoming excessive when fall is caused in either a right or left front wheel and the rear wheel on the same side of the fallen wheel is subject to anti skid control. SOLUTION: The brake operating quantity of the driver is detected, and the target brake pressure Pti of each wheel is calculated according to the brake operating quantity (S20), and the brake pressure of each wheel is electrically controlled so that it becomes the target braking pressure (S180). When one of the front wheels is fallen (S100), the target brake pressure of the front wheel is reduced (S140) by yaw moment adjustment correction so that the increasing rate of the target brake pressure of the front wheel on the side opposite to the fallen wheel becomes small when the rear wheel in the same side of this fallen wheel is subject to the anti skid control (S120), preventing unnecessary excessive yaw moment from working on wheels.

Abstract: PROBLEM TO BE SOLVED: To properly and surely control the movement of a vehicle by properly controlling the braking force of each wheel even when the defect is generated on either wheel by operating a target braking control amount of each wheel on the basis of the result of the detection of a defect state detecting means by a target braking control amount operating means. SOLUTION: Whether all the wheels are in normal state or not is judged (S15), and a next step is executed (S20) when the judgement is NO. This judgement is successively executed (S20, S25, S30), and the operation (S100) for distributing the braking force for four wheels, the operation (S600) for distributing the braking force for three wheels, the operation (S700) for distributing the braking force for two wheels, and the operation (S800) for distributing the braking force in one wheel are executed when the judgement in each step is YES, whereby a target slip ratio Sai of each wheel to be controlled is operated. Then the braking pressure of each wheel is controlled by feeding back the wheel speed to adjust the slip ratio Si of each wheel to the target slip ratio Sai (S900).

Abstract: PROBLEM TO BE SOLVED: To provide a brake liquid pressure control device capable of suppressing a drop of the braking performance even in case any unbraked wheel is generated owing to a liquid leak at any wheel cylinder. SOLUTION: A brake liquid pressure control device includes a controller to put an accumulator 38 in communication with the wheel cylinders 48FL-48RR of car wheels when a brake 12 is to be operated and control the liquid pressures of the cylinders 48FL-48RR, wherein a sensing means senses any failed wheel to be braked, and the controller shuts off the liquid pressure supplied from the accumulator to the applicable cylinder for the failed wheel and also makes appropriate control of the liquid pressures of the other wheel cylinders.

Abstract: PURPOSE: To improve estimation precision of reservoir accumulated inflow quantity in a liquid pressure control device to reduce wheel cylinder liquid pressure by supplying actuation liquid of a wheel cylinder to a reservoir. CONSTITUTION: Accumulated inflow quantity of actuation liquid to a reservoir 44 is estimated based on a pressure reduction time in which liquid pressure of both of a front and a rear wheel cylinders 16, 20 is reduced, and a car body deceleration. When the car body deceleration is large, the liquid pressure of the wheel cylinders 16, 20 is high, where the flow of the actuation liquid flowing from the wheel cylinders 16, 20 to the reservoir 44 is large. By thus estimating the accumulated inflow quantity of the actuation liquid considering the car body deceleration, as well as the pressure reduction time, estimation precision is improved, compared to the cases where it is estimated based on the pressure reduction time only. By estimating it based on the car body deceleration, need of a liquid pressure sensor is eliminated, thereby cost increase can be avoided while the estimation precision is improved.

Abstract: PURPOSE: To effectively prevent anti-skid brake control from being started/ended in its early stage by selecting a speed equivalent to an intermediate value out of the maximum drive wheel speed, the maximum rolling wheel speed and an estimated vehicle speed when it is judged that the maximum drive wheel is higher than the maximum rolling wheel speed while drive wheels are being accelerated in speed. CONSTITUTION: An ABS computer 14 operates an estimated body speed based on information from wheel speed sensors 12FR and 12FL, when it is estimated that the difference between the estimated vehicle speed and each wheel speed is equal to or more than a specified value, anti-skid control is thereby executed by an ABS actuator 16. When it is judged that the maximum drive wheel speed is higher than the maximum rolling wheel speed, and that the drive wheel speed is still accelerated, a speed equivalent to an intermediate value out of the maximum drive speed, the maximum rolling wheel speed and the estimated body speed is selected as a speed for estimating the estimated body speed.
