摘要： A wheel diameter judging system and wheel speed correcting system which calculates a driven wheel slip rate, and a driven wheel torque. A variation characteristic of the driven wheel slip rate relative to the variation in driven wheel torque is presumed using the method of least squares. A correction value corresponding to a ratio of the number of revolutions of a follower wheel to the number of revolutions of a driven wheel in a condition in which the driven wheel is not in a slipping state is calculated as an intercept of the driven wheel slip rate at the driving torque equal to zero in a graph of the variation characteristic. The driven wheel speed is corrected by the correction value. The driven wheel speed is corrected by the correction value. Thus, even if the driven wheel is in the slipping state, a difference in diameter between the follower and driven wheels can be accurately judged, and the follower wheel speed or the driven wheel speed can be accurately corrected.

摘要： A reference value for a traction control is calculated based on a vehicle speed. When a vehicle is in a predetermined turning state, so that a driven wheel speed is equal to or lower than a predetermined value and a lateral acceleration is equal to or larger than a predetermined value, a correction value is searched from a table based on the vehicle speed and a steering angle to correct an error of the reference value generated due to a difference between the locus of the driven wheels and the locus of the follower wheels during turning of the vehicle. The reference value is corrected by subtracting the correction value from the reference value (when the vehicle is a rear wheel drive vehicle) or by adding the correction value to the reference value (when the vehicle is a front wheel drive vehicle. Thus, the reference value for the fraction control such as a reference value for a target slip rate can be accurately in accordance with the turning state of the vehicle.

摘要： Drive wheel slip control system for a vehicle includes means for setting a reference value for slippage of a drive wheel providing an appropriate slip condition, means for reducing the drive wheel torque when the slippage exceeds the reference value, means for detecting the opening degree of an accelerator of a prime mover which drives the drive wheel, and means for correcting the reference value dependent on signals from the detecting means. The vehicle responds to accelerator operation even during control of the drive wheel slip, enabling a sporty travel.
