Abstract
A shift by wire-based transmission system and a method for controlling the same, may include a transmission lever, a main controller that determines a target gear stage and a current control delay time of an actuator based on a manipulation signal received from the transmission lever and controls driving of the actuator based on the determined target gear stage and the current control delay time to determine a gear stage position in a response to the driving of the actuator, and a transmission control unit that controls a hydraulic pressure based on the gear stage position determined by the main controller.
Claims18
A shift by wire-based transmission system comprising:
- a transmission lever;
- a main controller configured to determine a target gear stage and a current control delay time period of an actuator based on a manipulation signal received from the transmission lever and to control operation of the actuator based on the determined target gear stage and the current control delay time period to determine a gear stage position in a response to the operation of the actuator;
- and
- a transmission control unit connected to the main controller and configured to control a hydraulic pressure of a transmission based on the gear stage position determined by the main controller,
- wherein the main controller is configured to determine the current control delay time period of the actuator upon determining that the manipulation signal of the transmission lever is received during traveling of the vehicle in a regenerative braking control state.
A method of controlling a shift by wire-based transmission system, the method comprising:
- determining, by a main controller, a target gear stage and a current control delay time period of an actuator based on a manipulation signal of a transmission lever;
- controlling, by the main controller, operation of the actuator based on the determined target gear stage and the current control delay time;
- determining, by the main controller, a gear stage position in a response to the operation of the actuator;
- and
- controlling, by a transmission control unit, a hydraulic pressure of a transmission based on the gear stage position determined by the main controller,
- wherein the determining of the target gear stage and the current control delay time period of the actuator includes:
- determining the current control delay time period of the actuator upon determining that the manipulation signal of the transmission lever is received during traveling of a vehicle in a regenerative braking control state.
