Abstract:
A controller for a motor vehicle powertrain, the controller being configured to control the amount of torque generated by each of a plurality of drive torque sources in order to generate a net torque corresponding to a predetermined torque demand value, the predetermined torque demand value being determined at least in part by reference to a torque demand signal received by the controller, each drive torque source being coupled via a respective torque transfer arrangement to a respective group of one or more wheels, the controller being configured to cause at least one drive torque source to generate positive or negative torque in dependence on the predetermined torque demand value and to cause the drive torque source to undergo a torque reversal operation in which the direction of torque generated by the at least one drive torque sources changes from one direction to the other, the controller being configured wherein, during a torque reversal operation, the controller limits the rate of change of torque generated by the at least one of the plurality of drive torque sources as the amount of torque generated passes through zero and attempts to compensate for the reduction in rate of change of torque by a corresponding change in the amount of torque generated by one or more other of the plurality of drive torque sources.

Claim (Index 16):
A method of controlling a motor vehicle powertrain via a controller, the method comprising:\n controlling an amount of torque generated by each of a plurality of drive torque sources in order to generate a net torque corresponding to a predetermined torque demand value, the predetermined torque demand value being determined at least in part by reference to a torque demand signal received by the controller, each of the plurality of drive torque sources being coupled via a respective torque transfer arrangement to a respective group of one or more wheels; causing at least one of the plurality of drive torque sources to generate positive or negative torque in dependence on the predetermined torque demand value and causing the drive torque source to undergo a torque reversal operation in which a direction of torque generated by the at least one of the drive torque sources changes from one direction to another direction; and during a torque reversal operation, limiting a rate of change of torque generated by the at least one of the plurality of drive torque sources as an amount of torque generated passes through zero and attempting to compensate for a reduction in the rate of change of torque by a corresponding change in an amount of torque generated by one or more other of the plurality of drive torque sources.
