    摘要: A brake fluid pressure retaining unit for a vehicle comprises a solenoid valve SV arranged in a brake fluid passage FP between a master cylinder MC and a wheel cylinder WC so as to shut off or communicate the brake fluid passage FP. In the case that a transmission of the vehicle is shifted to a driving position, the solenoid valve SV is switched to a shut-off position when the vehicle stops with a brake pedal BP depressed. The solenoid valve SV is switched to a communicating position when driving force is exerted on the vehicle. Brake fluid pressure is retained within the wheel cylinder WC when the solenoid valve SV is in the shut-off position. The brake fluid pressure within the wheel cylinder is retained after releasing the brake pedal so that braking force continues to act on the vehicle. The brake fluid pressure retaining unit comprises control means CU such that when the solenoid valve is in the shut-off position and the transmission is shifted to a non-driving position, the solenoid valve SV is returned to the communicating position on condition that depression of the brake pedal BP is released.

    摘要: In a vehicle safety running system, while a contact probability estimation section estimates that there is a probability that a subject vehicle comes into contact with an object and an automatic braking section performs automatic braking, when the driver voluntarily performs a steering operation to avoid the contact, an automatic braking cancellation gradient is calculated based on the contact probability detected with the contact probability estimation section and the steering operation amount detected with the steering operation amount detection section, whereby automatic braking is cancelled at a speed corresponding to the automatic braking cancellation gradient so calculated. When the contact is easily avoided through the steering operation, the automatic braking cancellation gradient is set large so as to cancel automatic braking quickly, while when the contact is difficult to be avoided, the automatic braking cancellation gradient is set small so as to cancel automatic braking moderately.

    摘要: A system for controlling running safety of a vehicle having at least a brake, a steering mechanism manipulated by a vehicle operator, a laser radar for detecting an obstacle present ahead on a course of travel of the vehicle, and a brake actuator mechanism actuating the brake independently of the vehicle operator manipulation. In the system, a first threshold value (defined in terms of relative distance between the vehicle and the obstacle) for avoiding contact with the obstacle by steering and a second threshold value for avoiding contact by operating the brake actuator mechanism are determined and are compared with the detected relative distance. When the detected relative distance is less than the first threshold value, the brake actuator mechanism is immediately operated to generate a relatively small deceleration, thereby enabling effective obstacle avoidance to well meet the intention and desires of the vehicle operator, without causing a problem of interference with the steering of the vehicle operator, while preventing the control accuracy from being degraded.

    摘要: In an obstacle detection system for a vehicle which has a radar having an electromagnetic wave transmission device and a reflected wave reception device, the electromagnetic transmission device transmits electromagnetic waves in a direction in which the vehicle is traveling, and the reflected wave reception device receives reflected waves produced when the electromagnetic waves transmitted from the electromagnetic wave transmission device are reflected by an object present in the traveling direction of the vehicle. The system detects obstacles present in the traveling direction of the vehicle based on the result of a radar search operation, and it is possible to identify only those objects detrimental to the traveling of the vehicle as obstacles. An obstacle decision device decides whether or not the object detected by the radar is an obstacle, by using the detected value determined by a vehicle speed detection device which detects the speed of the vehicle, the calculated value determined by a relative distance calculation device that calculates a relative distance to the object present in the traveling direction of the vehicle based on the result of search operation by the radar, and the calculated value determined by an overlap calculation device that calculates an overlap in the width direction of the vehicle between the vehicle and the object according to the result of the search operation by the radar.

    摘要: A system for controlling running safety of a vehicle having an alarm and an automatic braking system. A plurality of decelerations &agr;2n of an obstacle such as another vehicle present ahead on the road is predicted and corresponding manipulated variables &agr;1n (braking amount) to be supplied to the vehicle which indicate possible deceleration of the vehicle are determined. Then threshold values L&agr;2n for alarming and automatic braking are determined corresponding to the predicted deceleration and are successively compared with the distance to the obstacle. When the distance falls below any of the threshold values, alarming or automatic braking is effected to avoid contact with the obstacle, thereby making the system relatively simple and enabling operation to match the driver's expectations.

    摘要: In a braking-force distribution control system for a vehicle, which is capable of controlling the ratio of a braking liquid pressure for front wheels to a braking liquid pressure for rear wheels based on a comparison of front and rear wheel speeds, a correcting factor is calculated in a correcting factor calculating device based on the ratio of front and rear wheel rotational speeds detected by front and rear wheel rotational speed sensors. At least one of front and rear wheel speeds, calculated in front and rear wheel speed calculating devices, is corrected by a wheel speed correcting device prior to the calculation of a control quantity in a control quantity calculating device. A control determining device determines whether the range of variation in correcting factor is equal to or larger than a preset value. When the range of variation in correcting factor is equal to or larger than the preset value, a signal indicative of a command to prohibit the calculation of the control quantity based on the result of the comparison of the front and rear wheel speeds in the control quantity calculating device is output from the control determining device. Thus, it is possible to perform an appropriate control of braking-force distribution taking a variation in dynamic radius of a tire into consideration.
