1. A control system for compensating for variable inertia in a vehicle powertrain of a hybrid vehicle having a first torque source comprising an internal combustion engine and a second torque source comprising an electric motor that can drive the vehicle while the first torque source is disconnected from wheels of the vehicle powertrain, the first torque source couplable to a first axle of the hybrid vehicle and the second torque source couplable to a second axle of the hybrid vehicle, the control system comprising one or more controllers, wherein the control system is configured to:
determine whether a torque source is coupled to a wheel; and
apply a torque change in dependence on an angular acceleration associated with the first torque source, in dependence on whether the first torque source is coupled to the wheel;
wherein the torque change is distributed between the first torque source and the second torque source;
wherein at least part of the torque change is provided by the second torque source; and
wherein the angular acceleration is obtained by obtaining the acceleration from a shaft speed sensor downstream of at least one gear train of a transmission, and then converting the acceleration to engine angular acceleration in dependence on a gear ratio of the at least one gear train.
