Abstract
Techniques for controlling the spin of driven wheels of a vehicle being driven over a surface, the vehicle also including nondriven wheels and an engine having a fuel system for varying engine torque. A characteristic signal representative of at least an estimate of the value of a traction characteristic of a surface under the vehicle is generated. A drive signal having a value dependent on the value of the characteristic signal is then generated. The engine torque is varied in response to the drive signal in order to control the spin of the driven wheels of the vehicle.
