Aspects of the present invention relate to a method and to a control system for a vehicle, the method comprising: receiving a torque request for an internal combustion engine configured to mechanically couple to a first axle of the vehicle; determining a shortfall relative to the torque request, dependent on torque providable by the engine; and providing an output to control an electric machine to provide a compensation torque configured to compensate for the shortfall, wherein the electric machine is mechanically coupled to a second axle of the vehicle.

Compensation method for shortfall of engine torque

Aspects of the present invention relate to a method and to a control system for a vehicle, the vehicle comprising an internal combustion engine configured to provide torque to a first axle of the vehicle for generating first axle wheel torque, and an electric machine configured to provide torque to a second axle of the vehicle for generating second axle wheel torque, the method comprising: outputting a torque request for the engine and a torque request for the electric machine, the torque requests having a first ratio dependent on a required torque split between the first axle wheel torque and the second axle wheel torque, wherein received first axle wheel torque and received second axle wheel torque have a second variable ratio dependent on a difference between wheel torque response capabilities of the engine and of the electric machine; determining that a trigger condition is satisfied; and controlling, in dependence on satisfaction of the trigger condition, determination of the torque request for the electric machine such that deviation of the second ratio from the first ratio is inhibited.

Torque distribution strategies for hybrid vehicles

Aspects of the present invention relate to a control module () for a vehicle powertrain. The powertrain comprises a transmission (), an engine () and an electric machine (). The control module () is configured to receive an input indicative of a requested upshift and in response to the received signal the control module () increases the torque output of the engine () prior to the start of the torque phase (). As the torque output of the engine () increases the control module () decreases the torque output of the electric machine () such that a constant wheel torque is applied to the wheels () during the torque phase () of the upshift.
