Abstract
Methods and system are provided to control engine torque of an engine of a vehicle. The methods comprise determining a drive torque demand on a crankshaft of an engine; determining an accessory torque demand on the crankshaft, the accessory torque demand comprising a first torque demand from a first e-machine and a second torque demand from a second e-machine; determining whether the sum of the drive torque demand and the accessory torque demand is greater than a usable torque capacity output from the engine crankshaft, and increasing a speed of the engine in response to determining that the sum of the drive torque demand and the accessory torque demand is greater than the usable torque capacity output from the engine crankshaft.
