Turf maintenance vehicle all-wheel drive system

摘要

A turf maintenance vehicle all-wheel drive traction control system includes a primary wheel propelling the vehicle. A first motor rotates the primary wheel. A traction control system has a first portion communicating with the first motor to monitor either a first motor current demand or a rotational speed of the primary wheel or the first motor and generates a traction control value. A secondary wheel rotated by a second motor steers the vehicle in a vehicle non-slip condition. A traction control system second portion determines a secondary wheel steering angle value. A speed threshold limit stored in the traction control system compared to the traction control value generates a slippage occurrence message indicative of a primary wheel traction loss event. A second motor drive signal created by comparing the steering angle value and the slippage occurrence message energizes the second motor during the traction loss event.
