Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
