Title: A self propelled vehicle with traction control
Inventor: CROSSLEY PAUL RICHARD
IPC: B60T8/175
Filed: 1993-09-13
Abstract: A self propelled road vehicle has two driven wheels and two undriven wheels with the driven wheels receiving a drive torque through a differential. The vehicle has a traction control system including means to measure the speed of the driven wheels and at least one of the undriven wheels. From these measurements the system determines a first error signal representing the average slip of the driven wheels and determines a second error signal representing the slip of one driven wheel relative to the slip of the other driven wheel. The system generates a first brake actuating signal which is the sum of the error signals which is applied to the brake of one or the driven wheel, and a second brake actuating signal, which is the difference of the error signals, which is applied to the brake of the second driven wheel. By this means the traction control applied to one driven wheel does not interact with the traction control applied to the other driven wheel. <IMAGE>
