摘要： A vehicle control system makes it possible to properly decide the passableness of a road curve in the forward direction of a subject vehicle by setting a tentative position ahead of an actual position by a tentative position setting mechanism M4, and calculates an estimated passage speed at the tentative position by an estimated passage speed calculating mechanism M5 on the basis of the distance between the actual position and the tentative position. A curve curvature radius calculating mechanism M6 and a curve length calculating mechanism M7 calculate the radius of curvature and length of a curve existing on a road ahead of the tentative position, on the basis of a map data outputted by a map data outputting mechanism M1, and a proper passage speed calculating mechanism M8 calculates the proper curve passing speed on the basis of the curvature radius and length of the curve. A passableness deciding mechanism M9 decides the passableness of the vehicle by comparing the estimated passing speed and the proper passing speed so that a vehicle control mechanism M10 controls the vehicle to allow it to pass the curve when it is decided that the vehicle cannot safely pass the curve.

摘要： In a vehicle collision preventing system, a possibility of collision of a subject vehicle against an object ahead of the subject vehicle is determined at least based on values measured by a distance measuring unit for measuring longitudinal and lateral distances between the subject vehicle and the object and a value detected by a subject-vehicle speed detecting device, an actuator is operated in accordance with the result of such determination to avoid the collision. A lateral relative distance of the subject vehicle and the object is calculated by a lateral relative distance calculating device based on the values measured in the distance measuring unit. Any of a judge level in the judgment of the collision possibility in a judging device or operation levels of actuators is changed in accordance with the result of the determination in a collision avoidance level determining device based on the lateral relative distance. Thus, the actuators are operated in accordance with a variation in lateral relative distance between the subject vehicle and the object, so that the collision preventing operations of the actuators are more easily accepted by a driver.

摘要： A hydraulic braking system having wheel cylinders, a tandem type master cylinder with first and second output ports, a hydraulic pressure transmitting device with a free piston slidably received in a housing with an input chamber located on one side of the free piston connected to the first output port in the master cylinder and an output chamber on the opposite side of said free piston leading to the wheel cylinders. An on-off valve is included, adapted to cut off the communication between a valve chest and the wheel cylinder in response to the hydraulic pressure in a pilot chamber leading to the first output port becoming larger than the hydraulic pressure in the valve chest by at least a given value. A differential pressure generating device is interposed between the second output port and the valve chest to reduce the output hydraulic pressure from the second output port in the master cylinder by a predetermined value to apply the reduced hydraulic pressure to the valve chest. This construction makes it possible to ensure that when a defect in hydraulic pressure is produced in a hydraulic pressure system connected to one of the output ports, a braking force is provided by an output hydraulic pressure from the other output port.

摘要： According to the present invention, the time during which the hydraulic braking pressure is intermittently maintained, is varied depending upon the degree of decrease in the wheel speed relative to the vehicle speed, so that the time may be prolonged when a large decrease occurs. Hence, unnecessary maintenance of the intermittent maintaining time is avoided in order to prevent any unnecessary operational noise from being produced.

摘要： A signal value on the basis of a lower wheel speed is compared with a signal value on the basis of a high wheel speed and, when the difference therebetween is larger than a predetermined value, a higher vehicle speed of two previously estimated vehicle speeds is used for anti-lock control and a reference value with which a wheel speed will be compared is derived from such vehicle speed. Thus, a range of condition for judging that wheels of a vehicle are about to be locked is enlarged.
