Abstract: A method of estimating a tire-road friction coefficient includes determining when the slope of a tire characteristic curve relating a utilized longitudinal friction of a tire to longitudinal slip of the tire is linear and non-linear. When the slope of the tire characteristic curve is linear, then the tire-road friction coefficient is estimated by correlating the slope of the tire characteristic curve to the tire-road friction coefficient. When the slope of the tire characteristic curve is non-linear, indicating that the tire is near or at saturation, then the tire-road friction coefficient is estimated by calculating a current utilized longitudinal friction of the tire.

Abstract: An apparatus provides improved vehicle handling during turning maneuvers by providing control of vehicle understeer. The understeer control includes determining a desired turning radius for the vehicle, a corresponding ideal outer to inner wheel speed ratio. A closed loop torque command is determined in proportion to the difference between the ideal wheel speed ratio and the actual wheel speed ratio. The closed loop torque command is used in conjunction with an open loop torque command responsive to operator power demand to provide wheel speed control in a manner to maintain the desired vehicle understeer characteristics.

Abstract: A method for monitoring the fuel pump includes estimating a pump speed and a nominal pump motor current in relation to a pump motor control signal and a fuel pressure. An armature resistance and a back-emf constant for the electric motor are determined corresponding to the estimated pump speed, a monitored pump motor current, and the pump motor control signal. A nominal armature resistance and a nominal back-emf constant for the electric motor are adjusted in relation to a pump motor temperature. Residuals are calculated based upon the adjusted nominal armature resistance, the adjusted nominal back-emf constant for the electric motor, the estimated armature resistance and the estimated back-emf constant for the electric motor. The residuals are compared with corresponding thresholds. A fault in the electric motor is detected based upon the comparisons of the residuals with the corresponding thresholds.
