摘要： A hydraulic braking pressure control system for a vehicle comprises a master cylinder (M) operatively connected to a brake pedal (P), an operation-amount detector (S) for detecting the amount by which the brake pedal is operated, a hydraulic pressure control unit (2.sub.FL etc.) for controlling the hydraulic pressure to be applied to a brake device (B.sub.FL etc.) mounted on a wheel in accordance with an applied quantity of electricity, and a control circuit (3) for controlling the quantity of electricity to be applied to the hydraulic pressure control unit, in accordance with a detection value provided by the operation-amount detector. The system further includes a cut-off valve (30.sub.FL etc.) adapted to be closed in response to depression of the brake pedal, and a reservoir (R.sub.2) connected through the cut-off valve to an oil passage (27) connecting the hydraulic pressure control unit and the brake device. The cut-off valve is opened when the brake pedal is not depressed, and even if a hydraulic pressure is delivered from the hydraulic pressure control unit when there is no braking operation, such hydraulic pressure can be released into the reservoir, ensuring that any such hydraulic pressure is prevented from being applied to the brake device.

摘要： A hydraulic braking pressure control system includes a shut-off valve (4) which is provided in an oil passage (58) connecting a brake device with an output port in a master cylinder and which is brought into a closed state by a control circuit when a braking operation is detected by an operation-amount detector, and a locking device (5) for inhibiting the closing of the shut-off valve when the output hydraulic pressure from a hydraulic pressure supply source in equal to or less than a predetermined value. The shut-off valve is opened when there is no braking operation, thereby ensuring that even if a hydraulic pressure is delivered from a hydraulic pressure control valve when there is no braking operation, such hydraulic pressure can be released into a reservoir. In addition, if the hydraulic pressure in the hydraulic pressure supply source is abnormally reduced, that shut-off valve is locked in its opened state by the locking device to ensure that the output hydraulic pressure from the master cylinder can be applied to the brake device.

摘要： A traction control device for a vehicle includes a control unit for operating wheel brakes for left and right driven wheels connected to a power source through a differential, when an excessively slipping tendency is produced in one or both of the driven wheels. In the traction control, an input torque supplied from the power source to the differential is detected by an input torque detecting device. A limit driving torque is determined based on a detection value detected by the input torque detecting device at the time when it is detected by a slip detecting device that only one of the driven wheels is fallen into the excessively slipping tendency. A braking torque to be applied to the one driven wheel is determined based on a value resulting from the subtraction of the limit driving torque from a current detection value detected by the input torque detecting device. Consequently, it is possible to reduce the control system into a relatively small size and to improve the control responsiveness and the hysteresis characteristic.

摘要： A braking force control system of a vehicle includes a deviation reference control quantity determining device for determining an operation control quantity for the actuator on the basis of a deviation between a target deceleration determined on the basis of a quantity of operation of a brake operating member and a detected deceleration of the vehicle. In this control system, the level of operation speed is judged in accordance with whether or not the variation per unit time in quantity of operation of the brake operating member exceeds a preset value. Following two states are switched over from one to another by a switch device: a state 1) in which the operation of the actuator is controlled with an operation control quantity determined in the deviation reference control quantity determining device, when it is decided that the operation speed is slow or low, and a state 2) in which the operation of the actuator is controlled with an operation control quantity determined in an operation quantity reference quantity determining device for determining the operation control quantity on the basis of the quantity of operation of the brake operating member, when the operation speed is fast or high. Thus, the generation of an overshooting can be avoided to improve the responsiveness.

摘要： A traction control device for a vehicle decreases the driving torque for a driving wheel connected to a power source through an automatic transmission in response to the detection of an excessively slipping tendency of the driving wheel at the time of acceleration of the vehicle. In the traction control device, the shifting motion of the automatic transmission is predicted by a shifting predicting means based on operational parameters of the power source and a shifting characteristic of the automatic transmission. The operational parameters of the power source are assumed by an foreseeing means based on values before shifting of the operational parameters of the power source and operational parameters of the vehicle as well as gear shift positions detected before and after shifting by a gear shift position detecting means. An actuator for changing the driving torque for the driving wheel is operated by a driving torque control section for determining a control quantity of driving torque based on detection values before shifting and assumed values after shifting of the operational parameters of the power source. As a result, the driving wheel speed is stabilized immediately at the completion of the shifting operation of the automatic transmission.

摘要： A braking force control system of a vehicle, capable of independently controlling at least braking forces of front wheel brakes, a braking force of a left rear wheel brake and a braking force of a right rear wheel brake. The braking force control system includes front wheel-side controls for controlling the braking forces of the front wheel brakes on the basis of a quantity of operation of a brake operating member and a deceleration of the vehicle, and rear wheel-side controls for independently controlling the braking forces of the left rear wheel brake and the right rear wheel brake on the basis of a turning level of the vehicle. Thus, it is possible to provide a sufficient braking force, while stabilizing the behavior of the vehicle, during braking in a turning state of the vehicle, by conducting a control of deceleration for the front wheels increased in load during braking, and by conducting a control of turning for the rear wheels largely contributing to the control of turning.
