Abstract: The present disclosure presents a wheel diameter variation-detecting device capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device can detect variation in diameter between a plurality of wheels of a vehicle, can detect rotational speeds of the respective wheels, and can calculate a variation parameter indicative of variation in diameter between the wheels using one of the wheels as a reference wheel, based on a result of comparison between the rotational speed of the reference wheel and that of one of the wheels other than the reference wheel. Further, the wheel diameter variation-detecting device can learn the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter obtained before the detected travelled distance reaches a predetermined distance.

Abstract: A method is provided to correct the wheel speed for a vehicle equipped with a mini tire as the spare tire plus a nonvolatile memory device. The presence or absence of a mounted mini tire is detected while the vehicle is moving, and if a mini tire is mounted, the mounting information is stored in the nonvolatile memory. If an antilock control is triggered after the vehicle is restarted and in motion, a correction is made for the mini tire using the mounting information stored in the nonvolatile memory.

Abstract: In order to avoid faults as a result of different diameters of tires, under prescribed conditions a correction of one wheel speed with respect to the other on each side of the vehicle is performed. The conditions are based on a comparison of the throttle valve angle to the zero torque angle, and a comparison of the speed of the driven wheel to the speed of the non-driven wheel.

Abstract: For evaluating the wheel speed signals (V(n)) required by an anti-locking or traction slip control system, a basic speed (VBas(n)) is derived from the speed signals of the individual wheels, and a wheel factor (Ki(n)) is formed for each wheel which, when multiplied by the wheel speed, forms the basic speed. For further signal processing, the wheel speed multiplied by the appertaining wheel factor is used in lieu of the actual wheel speed to form the reference speed, and the control signals.

Abstract: An apparatus for calculating vehicle-wheel revolution estimated values detects parameters such as the number of vehicle-wheel revolutions and vehicle-wheel revolution speeds, detects differences between the previous estimated values and the detected parameters or other parameters such as vehicle-wheel revolution speeds and accelerations calculated from the detected parameters, stores the differences at a predetermined rate, determines variations, and updates the estimated values based on the determined variations. Since the variations are determined so that the increase rate of the variations decreases as the accumulated values of the differences increase, lag time is minimized and at the same time noise is eliminated, thus precisely estimating the revolution values of the vehicle wheels. Antiskid control, traction control, and other controls can be effectively executed by using the estimated values even when the vehicle wheels move vertically on rough road surfaces or even when the vehicle wheels are eccentric. Consequently, the braking distance can be reduced, and the braking effects and the durability of control units are enhanced.

Abstract: A method of controlling a brake system comprises monitoring vehicle information with an electronic control unit. An algorithm is performed to detect the presence of a mini-spare tire assembly. A yaw offset value is pre-determined by the electronic control unit when a mini-spare tire assembly is detected at one of the steerable tire assembly locations. The yaw offset is then applied upon detection of a brake event.

Abstract: A method and system for calibrating speed of a vehicle having a plurality of wheels includes a wheel speed sensor coupled to each of the wheels for providing a first vehicle speed based on an average tire size associated with the plurality of wheels. A GPS sensor provides a second vehicle speed based on a change in position of the vehicle over a predetermined period of time. A control module automatically calibrates the speed of the vehicle based on a comparison of the first and second vehicle speeds.
