A vehicle includes an engine and a non-selectable-gear transmission having an electric machine mechanically coupled to the engine. The vehicle may have one or more controllers programmed to, in response to a request for passive neutral mode, pull-down the engine and inhibit engine pull-up while disabling the electric machine such that the vehicle coasts with minimal rotational inertia and electrical losses. The one or more controllers may be further programmed to, in response to a subsequent request for drive mode during the passive neutral mode, permit engine pull-up while enabling the electric machine such that the vehicle resumes drive.

Method and system to enable a coast-down mode

A hybrid-electric powertrain and control method for a vehicle having forward traction wheels and rearward traction wheels in an all-wheel drive configuration. An engine and an electric motor deliver power through delivery paths to the traction wheels. The power delivery paths may have multiple ratio gearing so that more power can be delivered mechanically to improve powertrain performance and to allow the electric motor size to be reduced. The powertrain includes a controller for automatically balancing power distribution to the forward and rearward traction wheels to avoid wheel slip.

Powertrain for a hybrid vehicle with all-wheel drive capability and method for controlling wheel slip

A hybrid-electric powertrain for a wheeled vehicle having an internal combustion engine, an electric generator, an electric motor and a battery. Transmission gearing establishes multiple torque flow paths including a forward drive torque flow path and a reverse drive torque flow path, the motor being isolated from forward drive gearing elements as it acts as a sole reverse drive power source.
