Aspects of the present invention relate to method and to a control system for compensating for variable inertia in a vehicle powertrain, the method comprising: determining whether a torque source is coupled to a wheel; and applying a torque change in dependence on angular acceleration associated with the torque source, in dependence on whether the torque source is coupled to the wheel.

Control system for torque source inertia compensation, method, vehicle and computer program

Aspects of the present invention relate to a method () and to a control system () for controlling at least one electric machine () of a vehicle () to support diagnostic testing of a vehicle system () comprising an internal combustion engine (), wherein the method () comprises: controlling a torque output () of the at least one electric machine () to allow a vehicle drive torque demand () to be met while the internal combustion engine () is operated within at least one torque threshold () for the diagnostic testing or operated at a torque setpoint () for the diagnostic testing.

Controlling an electric machine to support diagnostic testing

Aspects of the present invention relate to a control system and to a method of controlling a total driven wheel torque for a vehicle by controlling torque output of a first torque source of the vehicle and of a second torque source of the vehicle, wherein the first torque source is configured to provide drive torque to a first axle of the vehicle for generating first axle wheel torque, wherein the second torque source is configured to provide drive torque to a second axle of the vehicle for generating second axle wheel torque, the method comprising: receiving a total torque request for total driven wheel torque; producing a first torque request for the first torque source and a second torque request for the second torque source, in dependence on the total torque request for the total driven wheel torque; and when at least one of the first and second torque requests is not satisfiable, modifying at least one of the first and second torque requests to enable a sum of the first axle wheel torque and the second axle wheel torque to approach or satisfy the total torque request, wherein the modification of at least one of the torque requests is controlled by at least one torque rate modifier configured to increase or decrease a rate of change of at least one of the torque requests.
