Abstract
A controller may be configured to adjust a brake apply and release detection calibration based on a detection sensitivity associated with a predicted driver start/stop intention for a vehicle and an associated confidence level indicative of a likelihood of the predicted driver intention; and perform at least one of engine startup and engine shutdown according to the adjusted brake pedal detection calibration.
Claims20
A hybrid vehicle comprising:
- an engine configured for automatic shutdown and restart;
- and
- a controller configured to
- adjust a brake apply and release detection calibration based on a brake detection sensitivity level associated with a predicted driver start/stop intention for the vehicle and a confidence level indicative of a likelihood of the predicted driver intention derived from classified driving situation and event information, the calibration including a first brake pedal pressure threshold value at which the engine is shutdown, and a second brake pressure threshold value at which the engine is started;
- and
- perform at least one of startup of the engine and shutdown of the engine according to the adjusted brake pedal calibration.
