A method is provided for determining when to allow a vehicle engine to be placed in an engine standby mode. Various conditions, such as driver-controlled conditions, vehicle conditions, and energy management conditions, are compared to corresponding predetermined conditions. If at least some of the conditions match their corresponding predetermined conditions, the vehicle engine is allowed to be placed in a standby mode.

System and method for controlling stopping and starting of a vehicle engine

Rapidly changing torque demand is coordinated in an automotive vehicle having an engine and at least one motor. An engine base torque level indicating slowly changing torque produced by the engine is received. A motor torque is determined as a difference between a fast desired torque and the engine base torque level. An engine fast torque is determined as a difference between the request for fast desired torque and the motor torque. The motor torque is determined as a motor torque request and the engine fast torque is determined as an engine torque request.

Vehicle fast torque coordination

Torque demand is coordinated in a vehicle. Information defining at least one torque production limitation for a first torque producing device is received. A request for torque is compared with the first torque producing device torque production limitation. If the comparison does not result in the request for torque exceeding a limitation, a first coordinated torque request is determined as the request for torque and a null torque is determined as a second coordinated torque request. Otherwise, a first excess requested torque is determined as the difference between the request for torque and the exceeded limitation, the first coordinated torque request is determined as the exceeded limitation, and the second coordinated torque request is determined as the first excess requested torque.
