Abstract
A vehicle is provided that includes an engine and an electric machine operable to provide torque to drive the vehicle. A control system, including at least one controller, is configured to selectively and automatically start and stop the engine when the vehicle is in a first operating mode. The control system further includes control logic executable to place the vehicle in a second operating mode wherein the engine can be cranked but not started. The execution of the control logic to place the vehicle in the second operating mode is effected by operation of at least one vehicle system.
Claims20
A vehicle, comprising:
- an engine;
- an electric machine operable to provide torque to drive the vehicle;
- and
- a control system including at least one controller, the control system being configured to selectively and automatically start and stop the engine when the vehicle is in a first operating mode, the control system further including control logic executable to place the vehicle in a second operating mode wherein the engine can be cranked but not started, the execution of the control logic to place the vehicle in the second operating mode being effected by operation of at least one vehicle system.
A vehicle, comprising:
- an engine;
- an electric machine operable to provide torque to drive the vehicle;
- a control system including at least one controller, the control system being configured to effect at least two vehicle operating modes, including a normal operating mode and a first diagnostic operating mode, the normal operating mode including selective and automatic starting and stopping of the engine based at least in part on vehicle power requirements, the first diagnostic operating mode being effective to facilitate cranking of the engine and prohibit starting of the engine:
- and
- at least one vehicle system operable in a predetermined manner to change the vehicle operating mode from the normal operating mode to the first diagnostic operating mode.
A method for controlling an engine in a vehicle having an electric machine operable to provide torque to drive the vehicle, the vehicle including a first operating mode wherein the engine is selectively and automatically started and stopped based at least in part on vehicle power requirements, the method comprising:
- operating at least one vehicle system in a first predetermined manner to change the vehicle operating mode from the first operating mode to a second operating mode, thereby changing the vehicle operating mode without employing the use of a device external to the vehicle, the second operating mode facilitating cranking of the engine and prohibiting starting of the engine.
