摘要： A rolling motion stability control apparatus restrains a roll increasing tendency of a vehicle, with each wheel of the vehicle being braked by a wheel brake device. A first braking force control device is provided for applying a first braking force to the wheel, when the vehicle is turned to one direction. A second braking force control device is provided for applying a second braking force to the wheel, when the vehicle is turned to the other direction. A terminating control adjustment device is provided for adjusting the braking force control devices to continue the first braking force being applied, until the second braking force is initiated to be applied, when the vehicle is turned to the one direction, and then to the other direction.

摘要： A tire parameter estimation device that is economical and can accurately estimate tire parameters while taking into consideration both states of a vehicle and states of a road environment. A &mgr; gradient detecting circuit detects a &mgr; gradient on the basis of a wheel speed detected by a wheel speed detecting circuit. A gradient value comparing circuit determines a &mgr; gradient section value &mgr;r, which is a mean value of the &mgr; gradients from the &mgr; gradient detecting circuit, and calculates a rate (=&mgr;r/&mgr;I) of the &mgr; gradient mean value &mgr;r with respect to a &mgr; gradient initial value &mgr;. A tire temperature estimating circuit stores a table representing the relation between the rate and a tire temperature, and estimates a tire temperature corresponding to the rate calculated by the gradient value comparing circuit as the present tire temperature.

摘要： A hydrostatic power steering system including an electric motor is provided for a automotive vehicle. The hydrostatic power steering system utilizes a power steering piston responsive to movement of the rack element of the rack and pinion steering connection. The power steering piston is provided in a piston chamber divided by a valve land into first and second portions, each of which are connected to first and second hydraulic lines. A torque sensor is connected to the steering shaft for providing an output torque signal to a power steering controller. The electric motor of the system is responsive to a command signal generated by the power steering controller. An electrically operated valve is connected to the hydraulic lines and is adapted to receive a signal from the power steering controller for controlling flow of hydraulic fluid to the power steering chamber. The electrically operated valve arrangement is rendered inoperative within a predetermined zone defined by the command signal and the output torque signal.

摘要： Steering and braking are coordinated and controlled according to a sensed yaw rate error or lateral acceleration error to increase vehicle stability without increasing braking distance. A desired yaw rate or lateral acceleration rate is computed from the vehicle velocity and the steering wheel angle. If the yaw rate or the lateral acceleration is excessive, indicating instability, and the brakes are being operated, then both steering and braking are controlled to reduce the yaw rate or lateral acceleration rate. In all other cases, steering control alone is performed. The yaw rate or lateral acceleration rate is reduced under steering control by adjusting wheel positions in a direction opposite the direction of yaw or lateral acceleration. The control system of the present invention is applicable to both two-wheel and four-wheel steering and braking. The yaw rate or lateral acceleration is further reduced under braking control by decreasing brake pressure on a side of the vehicle corresponding to the direction of yaw or lateral acceleration and increasing brake pressure on the opposite side of the vehicle. In the case of anti-lock brakes, pressure is not increased beyond a slip rate threshold. Rather than controlling brake pressure, the slip rate threshold itself may be controlled in like manner to reduce the yaw rate or lateral acceleration.
摘要翻译：根据感测到的横摆角速度误差或横向加速度误差来协调和控制转向和制动，以增加车辆稳定性而不增加制动距离。从车辆速度和方向盘角度计算出期望的偏航率或横向加速度。如果偏航率或横向加速度过大，指示不稳定性，并且制动器正在操作，则控制转向和制动以减小偏航率或横向加速度。在所有其他情况下，仅执行转向控制。通过在与偏航方向或横向加速度方向相反的方向上调整车轮位置，在转向控制下减小偏航率或横向加速度。本发明的控制系统适用于两轮和四轮转向和制动。在制动控制下，横摆速度或横向加速度进一步减小，通过减少对应于偏航方向或侧向加速度的车辆侧的制动压力并增加车辆相对侧上的制动压力。在防抱死制动器的情况下，压力不会超过滑动率阈值。而不是控制制动压力，可以以相似的方式控制滑移率阈值本身以减小横摆率或横向加速度。

摘要： The steering stability of a moving vehicle is maintained by measuring an actual yaw rate of the vehicle and determining a desired yaw rate of the vehicle. An output signal is produced in response to a comparison of the actual and desired yaw rates. The angle of steerable wheels of the vehicle is controlled in response to the output signal in a manner tending to substantially conform the actual yaw rate to the desired yaw rate, thereby maintaining vehicle stability. The steerable wheels are steered by a steering wheel, and are independently steered in response to the output signal. Alternatively, the steerable wheels are steered solely in response to the output signal.
