Temporary engine start or stop using paddle shifter
A vehicle includes an internal combustion engine, a driver interface having a first driver-activated selector, and a controller. The controller selectively operates the engine according to a first mode and a second mode. In the first mode the engine runs continuously. In the second mode the engine is turned off in response to a first set of operating conditions and turned on in response to a second set of operating conditions. The controller further, in response to a driver activation of the first selector, controls the engine according to the first mode and, in response to an anticipated end of a first vehicle acceleration event subsequent the driver activation of the first selector, controls the engine according to the second mode.
1. A vehicle comprising:
an engine; and
a controller configured to operate the engine
in a continuous on mode in response to driver input,
in a stop/start mode in response to an anticipated end of a first vehicle acceleration event following the driver input,
in a continuous off mode in response to further driver input, and
in the stop/start mode in response to an anticipated vehicle acceleration event following the further driver input.
2. The vehicle of claim 1 , further comprising a vehicle steering wheel paddle, wherein the driver input is received via the paddle.
3. The vehicle of claim 1 , wherein the anticipated end of a first vehicle acceleration event is based on a negative change in vehicle acceleration in a forward direction.
4. The vehicle of claim 3 , wherein the negative change lasts for a duration exceeding a predefined time interval.
5. The vehicle of claim 1 , wherein the anticipated end of a first vehicle acceleration event is based on a change in position of an accelerator pedal or a brake pedal.
6. The vehicle of claim 1 , further comprising a display configured to signal a driver that the engine is being operated in the continuous on mode, wherein the controller is further configured to activate the display while operating the engine in the continuous on mode.
7. The vehicle of claim 1 , further comprising a display configured to signal to a driver that the start/stop mode is unavailable, wherein the controller is further configured to activate the display and inhibit operating the engine in the start/stop mode in response to presence of a predefined set of operating conditions.
8. A vehicle comprising:
an engine; and
a controller configured to, in response to driver input, the engine being on, and an engine running requirement not being satisfied, automatically stop the engine and maintain the stop until first occurrence of a vehicle acceleration increase, and in response to additional driver input and the engine being off, automatically start the engine and maintain the engine running until first occurrence of a vehicle acceleration decrease.
9. The vehicle of claim 8 , wherein the vehicle acceleration decrease corresponds to a release of an accelerator pedal or actuation of a brake pedal.
10. The vehicle of claim 8 , wherein the vehicle acceleration increase corresponds to a release of a brake pedal or actuation of an accelerator pedal.
11. The vehicle of claim 8 , further comprising a display configured to signal to a driver that the engine may not be stopped, wherein the controller is further configured to activate the display in response to the driver input and the engine running requirement being satisfied.
