Abstract
An engine speed matching system for a vehicle with a manual transmission includes a sensor that senses an input shaft speed of the manual transmission during a shift. A control module receives the input shaft speed, determines an engine speed, determines a desired engine speed based on the input shaft speed and the engine speed, and adjusts the engine speed based on the desired engine speed and the input shaft speed before the shift is completed.
Claims15
An engine speed matching system for a vehicle with a manual transmission, the engine speed matching system comprising:
- a sensor that senses an input shaft speed of the manual transmission during a shift;
- and
- a control module that receives the input shaft speed, that determines an engine speed, that determines a desired engine speed based on the input shaft speed and the engine speed, and that adjusts the engine speed based on the desired engine speed and the input shaft speed before the shift is completed,
- wherein the control module disables adjusting the engine speed based on the desired engine speed and the input shaft speed before the shift is completed in response to an accelerator pedal position during the shift.
An engine speed matching method for a vehicle with a manual transmission, the method comprising:
- sensing an input shaft speed of the manual transmission during a shift using a sensor;
- receiving the input shaft speed;
- determining an engine speed;
- determining a desired engine speed based on the input shaft speed and the engine speed;
- adjusting the engine speed based on the desired engine speed and the input shaft speed before the shift is completed;
- and
- disabling adjusting the engine speed based on the desired engine speed and the input shaft speed before the shift is completed in response to an accelerator pedal position during the shift.
