Abstract
An automotive vehicle includes an engine and at least one controller. The at least one controller receives information about steering angle velocity or steering input torque during an engine auto stop event, and determines whether to allow the engine to auto stop based on the received information.
Claims15
An automotive vehicle comprising:
- an engine;
- and
- at least one controller configured to (i) receive information about steering angle velocity or steering input torque during an engine auto stop event, (ii) detect an engine auto stop inhibit condition when one of the steering angle velocity or steering input torque exceeds a threshold value, and (iii) inhibit an auto stop of the engine in response to detecting the engine auto stop inhibit condition.
A method for controlling an automotive vehicle engine comprising:
- receiving information about steering angle velocity or steering input torque during an engine auto stop event;
- detecting an engine auto stop inhibit condition when one of the steering angle velocity or steering input torque exceeds a threshold value;
- and
- inhibiting an auto stop of the engine in response to detecting the engine auto stop inhibit condition.

A micro hybrid vehicle comprising:
- an engine;
- and
- at least one controller configured to determine whether to allow the engine to auto stop based on information about steering input torque or rate of change of steering angle.
