Abstract
Systems, methods and a processor are provided for adjusting the spark timing of an internal combustion engine. The systems, methods and processor include adjusting the spark timing of an internal combustion engine configured to power a vehicle toward peak torque timing based on an output of a longitudinal acceleration sensor configured to sense a longitudinal acceleration of the vehicle.
Claims19
A method of operating an engine positioned in a vehicle, comprising:
- oscillating spark timing during engine operation at a frequency;
- adjusting a spark timing of the engine toward peak torque timing based on an amplitude of longitudinal acceleration of the vehicle resulting from said oscillating.
A method of operating an engine positioned in a vehicle, comprising:
- adjusting spark of the engine timing during steady vehicle operation;
- further adjusting spark timing toward peak torque timing based on an amplitude of longitudinal acceleration of the vehicle resulting from said adjusting during steady vehicle operation, the longitudinal acceleration indicated by a sensor coupled in an electronic stability system of the vehicle.
A method of operating an engine positioned in a vehicle, comprising:
- adjusting spark of the engine timing during steady vehicle operation;
- further adjusting spark timing toward peak torque timing based on an amplitude of longitudinal acceleration of the vehicle resulting from said adjusting during steady vehicle operation, the longitudinal acceleration indicated by a sensor coupled in a roll-over stability system of the vehicle.
