    摘要: According to the method of the present invention, when the vehicle speed has become less than the reference speed, after a reduction in the hydraulic braking pressure during braking, the hydraulic braking pressure is gradually increased. According to the above method, the rate of increase of the hydraulic braking pressure is moderated when the vehicle speed has become less than a reference value. This will avoid the degradation in braking feeling due to a rapid increase in hydraulic braking pressure for a wheel brake.

    摘要: Hydraulic braking pressure device which includes a casing divided into a first cylinder portion and a second cylinder portion by a partition. A first piston is slidably fitted in the first cylinder portion and defines an input chamber between one end face thereof and the partition which is connectible to an output port of a master cylinder. The opposite end face of the first piston and the end of the first cylinder portion define a control chamber connectible with an anti-lock control mechanism. A second piston is slidable fitted in the second cylindrical portion and defines an output chamber between one end face thereof and the partition which is connectible to a wheel brake. The opposite end face of the second piston and the end of the second cylinder portion define a spring chamber in which a spring is housed biasing the second piston towards the partition. The first and second piston are fitted to both ends of a piston rod which penetrates movably and sealingly through the partition. A valve mechanism is provided in the partition and closes in response to movement of the second piston away from the partition cutting off communication between the input and output chambers. The sectional area of the first piston is smaller than that of the second piston.

    摘要: A braking oil pressure control device for a hydraulically operated anti-skid brake system comprising a pair of serially aligned first and second cylinder chambers defined in a cylinder body on the opposite sides of a partition wall. The first cylinder chamber is divided by a brake piston on the opposite sides thereof into a first brake chamber communicating with a brake master cylinder and a second brake chamber communicating with a wheel brake such that when the pressure in the first brake chamber is pressurized under the action of the master cylinder, the brake piston is moved to pressurize the second brake chamber for actuation of the wheel brake. A control piston is slidably received in the second cylinder chamber and cooperates with the partition wall to define a control chamber communicating with an anti-skid brake control hydraulic circuit. The control piston is connected with the brake piston such that when the control chamber is pressurized by the anti-skid control hydraulic circuit, the control piston is moved together with the brake piston in the direction of reducing an excessive brake pressure in the second brake chamber. A supplementary oil chamber leading to an oil reservoir is formed in the cylinder body and communicates via the second brake chamber with a first seal cup permitting a unidirectional flow of operating oil from the supplementary chamber to the second brake chamber. A second seal cup is interposed between the first and second brake chambers for permitting a unidirectional flow of operating oil from the first brake chamber to the second brake chamber.

    摘要: A profile of a designated road by which a vehicle is guided to a destination is predicted by road map data. In the case where it is difficult for the own vehicle to pass through a curve of the designated road ahead of the own vehicle, a warning is given to a driver or vehicle speed is automatically reduced. Whether or not the car is correctly running on the designated road is decided by deviation &Dgr;&thgr; (=&thgr;V−&thgr;M) between azimuth angle &thgr;V of the actual advancing direction of the own vehicle and azimuth angle &thgr;M of the designated road. When it is decided that there is a possibility that the own vehicle is running off the designated road, the warning is given or automatic speed reduction is stopped or suppressed. Due to the foregoing, it is possible to prevent the own vehicle from being improperly controlled and it becomes possible for a driver from feeling a sense of incongruity.

    摘要: A navigation system is provided where an error in the road data and an omission of the road data can be compensated for, and a vehicle control system is provided for using the navigation system. A yaw rate generation starting position, a yaw rate peak position and a yaw rate generation finishing position of a traveling vehicle are detected. The three positions determined are an inlet position, a central position and an outlet position of a curved road. If the three positions are offset to positions of nodes N2, N3 and N4 on the curved road stored in a map information storing means of the navigation system, the positions of the nodes N2, N3 and N4 are corrected so that they are matched with the three positions. It is determined based on the corrected road data whether it is possible for a subject vehicle to pass through a road ahead of the subject vehicle. When it is impossible for the subject vehicle to pass through the road, a warning to a driver or an automatic speed reduction is carried out.

    摘要: A system for controlling behavior of a vehicle having a laser radar for detecting an obstacle present on a road on which the vehicle is traveling and operating the brake automatically to avoid contact with the obstacle, and having a power-assist steering actuator including an electric motor installed in the steering system. In the system, it is determined whether the vehicle is steered by the steering wheel as manipulated by the vehicle operator or the vehicle is steered by a force generated by the interplay between the tire and road due to the automatic braking and, when vehicle is steered by the force generated by the tire/road interplay, the electric motor of the steering actuator is controlled to drive in the direction to cancel the force, thereby preventing the vehicle behavior from degrading to deviate from the desired course of travel and preventing various disadvantages such as failure to achieve the desired obstacle detection necessary for an effective obstacle avoidance control.
