Vehicle traction control

摘要

A method for controlling wheel slip comprising determining an actual wheel slip of a set of driven wheels on a vehicle, adjusting the actual wheel slip for cornering distortion, setting a target slip condition using a traction control unit with a multi-position switch depending upon road conditions, calculating overslip of the wheels, and retarding an engine output to minimize overslip, and an apparatus for accomplishing same.

主权项

1. A vehicle control system comprising:
an engine; an engine control unit; a traction control system including a processor; a slip selection switch; a plurality of wheels, where some wheels are driven and some wheels are not driven; and wheel sensors; wherein the vehicle wheel control system interprets signals from the wheel sensors and the slip selection switch, and determines a target slip; and the vehicle wheel control system then sends a command to the engine control unit to reduce the engine output according to a predetermined value for the target slip; and wherein the processor further outputs four digital pulse outputs for each wheel that is used for electronic recording and datalogging; and wherein the output signal is divided to prevent an output pulse rate from exceeding a maximum input frequency of a reading device.
