摘要： A traction control system for a vehicle includes a calculator for calculating a speed of a driven wheel of the vehicle, a calculator for calculating a vehicle speed and a calculator for calculating a slip rate of the driven wheel on the basis of the driven wheel speed and the vehicle speed, such that the feed-back control of a throttle valve is carried out to reduce the output torque from an engine to inhibit the excessive slipping of the driven wheel, when the slip rate exceeds a predetermined threshold value. The system further includes a calculator for calculating a total grip force of the vehicle, a calculator for calculating an initial engine required torque at the start of the feed-back control of the throttle valve on the basis of the total grip force, and a calculator for calculating an initial throttle opening degree of the throttle valve on the basis of the initial engine required torque. Thus, the excessive slipping of the driven wheels can be reduced without an abrupt change exerted to the behavior of the vehicle by setting an appropriate initial throttle opening degree.

摘要： A system is provided to prevent suspension judder from being generated at the start of a vehicle which includes a traction control system. If the starting of the vehicle is detected based on driving-wheel speeds RL and RR, a shift position and an accelerator opening degree .theta.th1, an initial torque TQ2 and a delay time are map-searched based on the accelerator opening degree .theta.th1 and a steering angle .theta.st. The driving force for driven wheels is limited to the initial torque TQ2, until a delay time from the starting of the vehicle has elapsed, to prevent the generation of suspension judder. When the delay time has elapsed, an accelerating increment torque TQ3 is map-searched based on the accelerator opening degree .theta.th1 and the steering angle .theta.st, and is added to the initial torque TQ2, thereby ensuring the accelerating performance of the vehicle.

摘要： A steering angle detecting system for a vehicle includes a sensor responsive to rotation of a steering wheel for generating angular pulses corresponding in number to the steering angle of the steering wheel. Another sensor generates a reference pulse at a predetermined angle of the steering wheel. The angular pulses are counted by a counter. The steering angle detecting system is determined to be abnormal if the counted value of the counter is not within a predetermined value range when the reference pulse is generated. Further, the rate of change of the counted value by the counter is detected, and the steering angle detecting system is determined to be abnormal if the detected rate of change of the counted value is greater than a predetermined value. Further, the steering angle detecting system is determined to be abnormal if the detected rate of change of the counted value has continued to be smaller than a predetermined value for a predetermined time period or longer.

A reference yaw rate generator generates a reference yaw rate in response to an input from the steering angle memory, and a yaw rate detector detects the yaw rate of the vehicle. Further, a yaw motion corrector controls the yaw motion of the vehicle in response to the outputs from the reference yaw rate generator means and the yaw rate detector. The yaw motion control device set forth above can also be employed with a vehicle speed detector for detecting the speed of the vehicle, and for outputting the vehicle speed to said reference yaw rate generator to provide greater accuracy in controlling the yaw motion of the vehicle.
