摘要： In a stabilizer apparatus for a vehicle, an electronic control unit calculates a target current of an electric motor from vehicle speed, steering angle, and lateral acceleration, and increases and decreases actual current such that the calculated target current flows through the motor. The control unit decreases the actual current by a predetermined amount when the difference between the target current and the actual current becomes smaller than a predetermined value during control of increasing the actual current. The predetermined amount is equal to the difference between the determined target current at the time of the detection of the difference and current which is necessary to obtain, during control of decreasing the actual current, an output torque equal to the output torque of the speed reduction mechanism obtained as a result of the target current flowing through the electric motor.

摘要： The vehicle operation control apparatus multiplies the variable gain G controlled based on the vehicle velocity V, the steering angle &thgr;h, the steering angle velocity &ohgr;h and the actual steering angle &thgr;T with the steering angle &thgr;h, and controls the actual steering angle &thgr;T of the driven wheels on a result of this multiplication. Consequently, the additional turning time gear ratio Ga1 or the turning-back gear ratio Ga2, set up individually, can be selected depending on the turning direction of the steering wheel. Therefore, the steering feeling both at the time of additional turning and turning-back can be improved.

摘要： The present invention relates to an antilock brake system having an electrically controlled hydrostatic motor and pump system. The inventive ABS improves stability and maneuverability during braking by reducing or eliminating vibration and noise problems due to conventional on/off solenoid valve control. In accordance with exemplary embodiments, a two position solenoid is actuated (i.e., energized) in response to initiation of an ABS control mode. Once activated, the solenoid remains energized for the duration of the ABS control mode. Because the solenoid remains continuously activated during the ABS control mode, the vibration and noise associated with repeatedly activating and deactivating a solenoid is reduced or eliminated. To effect pressure increases and decreases in a braking channel during the ABS control mode, a reversible (i.e., bi-directional) pump is provided in each braking channel. To further enhance the smoothness of the braking, the reversible pump is controlled with an analog command signal that is, for example, proportional to a difference between wheel deceleration/acceleration detected for the channel and a vehicle's deceleration/acceleration.
摘要翻译：本发明涉及一种具有电控液压马达和泵系统的防抱死制动系统。本发明的ABS通过减少或消除由于常规的开/关电磁阀控制引起的振动和噪声问题而改善了制动期间的稳定性和机动性。根据示例性实施例，响应于ABS控制模式的启动，两位置螺线管被致动（即，通电）。一旦激活，电磁阀在ABS控制模式的持续时间内保持通电。因为在ABS控制模式期间螺线管保持连续的激活，所以减少或消除与反复激活和停用螺线管相关联的振动和噪音。为了在ABS控制模式期间实现制动通道中的压力增加和减小，在每个制动通道中提供可逆（即，双向）泵。为了进一步提高制动的平滑度，可逆泵由模拟命令信号控制，该模拟指令信号例如与通道检测到的车轮减速度/加速度差与车辆的减速/加速度成比例。

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 and producing an output signal in response to a comparison of the actual and desired yaw rates. The steering 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 by a motor in response to the output signal. The motor comprises a fluid motor. Additionally, valves are provided to stop the flow of fluid in the event that a malfunction occurs.

摘要： A stability augmentation system and 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. 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. The stability augmentation system includes a hydraulic system having a separate oil pump and electric motor. The motor is controlled by a stability augmentation system controller through inputs from a steering wheel angle sensor, vehicle speed sensor, yaw rate sensor and a position sensor.
