    • In a vehicle behavior control system, a target braking force applied to each wheel of the vehicle is obtained based on a master cylinder pressure so as to be proportional to a vertical load of each wheel. When it is determined that a braking force is applied to the vehicle running on a road with uneven friction coefficient, an excess yaw moment caused by the difference between the target braking force and an actual braking force is calculated. A steering angle is corrected with a correcting steering angle estimated based on the excess yaw moment. A yaw rate difference is calculated as a difference between a normal yaw rate and an actual yaw rate of the vehicle based on the steering angle that has been corrected. It is determined whether the vehicle behavior is deteriorated based on the yaw rate difference. The vehicle behavior is then controlled to reduce the yaw rate difference.
    • 在车辆行为控制系统中,基于主缸压力获得施加到车辆的每个车轮的目标制动力,以便与每个车轮的垂直负载成比例。 当确定对在摩擦系数不均匀的道路上行驶的车辆施加制动力时,计算由目标制动力和实际制动力之间的差引起的过大的横摆力矩。 用基于过大横摆力矩估计出的修正转向角修正转向角。 基于已经被校正的转向角,偏航率差被计算为正常横摆率和车辆的实际横摆角速度之差。 基于横摆率差异来确定车辆行为是否劣化。 然后控制车辆行为以减小横摆率差异。

    • A clamping device which holds a workpiece at a predetermined position during a machining operation of the workpiece comprises a clamper for clamping a workpiece, a feed device for moving the clamper in the axial direction, a load sensor which is fixed to the clamper and detects a clamping force acting on the workpiece, and a memory in which a target clamping force corresponding to the shape of the workpiece and a method of machining operation is stored. The control device compares the clamping force detected by the load sensor with the target clamping force stored in the memory and controls the clamper in response to the deviation between the detected clamping force and the target clamping force. The clamping device also has a position detecting means for detecting the axial position of the clamper. The control device compares the present position detected by the position detecting means with a stop position which is detected during the initial clamping and is stored in the memory, and controls the clamper in proportion to the deviation between the detected position and the stored stop position.
