Abstract
A system of controlling shift for a vehicle may include a data detector configured to detect data for a shift control; a road shape determiner configured to determine a road shape of an inclined road based on the data; an engine brake tendency determiner configured to determine an engine brake operating tendency of a driver based on the data; and an engine brake operating stage determiner configured to determine an engine brake operating stage based on the road slope and the engine brake operating tendency of the driver, wherein the system controls the shift according to the engine brake operating stage determined by the engine brake operating determiner.
Claims14
A system of controlling shift for a vehicle comprising:
- a data detector configured to detect data for a shift control;
- a road shape determiner configured to determine a road shape of an inclined road based on the data;
- an engine brake tendency determiner configured to determine an engine brake operating tendency of a driver based on the data;
- and
- an engine brake operating stage determiner configured to determine an engine brake operating stage based on the road shape and the engine brake operating tendency of the driver,
- wherein the system controls the shift according to the engine brake operating stage determined by the engine brake operating determiner.
A method of controlling shift for a vehicle comprising:
- detecting data for a shift control;
- determining whether the vehicle currently coasts on a downhill road;
- determining whether a shift mode of the vehicle is a manual shift mode when the vehicle currently coasts on the downhill road;
- determining an engine brake handling tendency index when the shift mode of the vehicle is the manual shift mode;
- determining an engine brake operating stage based on the engine brake handling tendency index;
- and
- controlling a shift according to the engine brake operating stage when the shift mode of the vehicle is an automatic shift mode.
