摘要： A wheel speed detecting device for a vehicle having wheel speed detectors for detecting left and right wheel speeds, respectively; a turning state detector for detecting the turning state of the vehicle; and a correcting and calculating device for correcting the wheel speeds on the basis of an output from the turning state detector and for calculating a value representative of the left and right wheel speeds on the basis of the corrected wheel speeds. Thus, an error of wheel speeds detected during turning of the vehicle can be compensated for, thereby determining a correct wheel speed.

摘要： A steering stability control system for a vehicle includes a turning state judging device for judging turning state of the vehicle to output an oversteering signal or an understeering signal, and a steering stability control device for controlling an output torque from an engine on the basis of an output from the turning state judging device. This system further includes a counter-steering judging device capable of judging a counter-steering state of the vehicle and causing the turning state judging device to output an oversteering signal when the counter-steering state is judged. Thus, it is possible to reliably judge the oversteering and the understeering during turning of the vehicle.

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 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： When a steady straight advancing state presuming device presumes that the vehicle is in a steady straight advancing state, and a slip rate calculating device calculates a small slip rate, based on an output from a driving-state detecting device, or when the steady straight advancing state presuming device presumes that the vehicle is in the steady straight advancing state, and a driven wheel torque calculating device calculates a small driven wheel torque, based on the output from the driving-state detecting device, a correction execution determining device determines that the vehicle is in a stable state suitable for correcting the wheel speed. By a command from the correction execution determining device, a correcting device corrects the driven wheel speed or the follower wheel speed based on a speed ratio of the driven wheel speed to the follower wheel speed calculated by a speed ratio calculating device. Thus, when a different-diameter tire has been mounted on a wheel, it is possible to precisely correct the wheel speed without being influenced by the slipping of the driven wheels or by the turning of the vehicle.

摘要： A technique to indicate a different-diameter wheel such as a temporary tire and to accurately correct the wheel speed of the different-diameter wheel is determined. Wheel speeds of a pair of left and right driven wheels are detected by wheel speed sensors and wheel speeds of a pair of left and right follower wheels are detected by wheel speed sensors. Yaw rates are calculated from the wheel speeds of the left and right wheels, and yaw rates are calculated from the wheel speeds of the wheels located diagonally. Which wheel of the four wheels is a different-diameter wheel is determined based on the magnitudes of the four yaw rates and the wheel speed of the different-diameter wheel is corrected based on a ratio in wheel speed between the different-diameter wheel and the other wheels.

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.
