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 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： 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.

摘要： A fluid pressure control system which includes an operational reaction force generating device having a piston which includes a front surface facing a pressure chamber and is operatively connected to an operating member so as to reduce a volume of the pressure chamber in response to the operation of the operating member. The fluid pressure control system further includes a fluid pressure control valve capable of adjusting and outputting an output pressure from a fluid pressure supply source capable of outputting a constant fluid pressure in accordance with the operation amount of the operating member and a stroke accumulator connected to the pressure chamber. The stroke accumulator is of a structural arrangement such that the resilient biasing force acting on the accumulator piston by the movement of the back-up piston toward the accumulator piston with the abnormal reduction in fluid pressure in the pilot chamber connected to the fluid pressure supply source is increased more than the fluid pressure acting on the accumulator piston when the fluid pressure in the pilot chamber is normal. Thus, it is possible in the fluid pressure control system of this invention to prevent the amount in which the operating member operates from being increased more than necessary when the output fluid pressure from the fluid pressure supply source is abnormally reduced.

摘要： A traction control method for a vehicle, comprising the steps of: judging an excessive slipping state of a plurality of driving wheels by taking into account, as at least one judgment requirement, whether or not a driving-wheel speed exceeds a braking-force controlling target wheel speed determined by taking into account a predetermined slip rate of a vehicle speed, and controlling a braking force for the driving wheels in accordance with the result of the judgment, wherein the intensity of a slipping tendency for every one of the driving wheels is determined on the basis of a judgment value which is set larger than the vehicle speed and smaller than the braking-force controlling target wheel speed, and the smaller the number of the driving wheels determined to have a large slipping tendency, the more the braking-force controlling target wheel speed is increased. This prevents the occurrence of an excessive control of braking force, when the slipping tendency of only a part of the driving wheels is large.
