Abstract
An apparatus and a method for controlling shifting of a vehicle are provided. The apparatus includes a transmission configured to transmit power generated from by a motor to a vehicle wheel, and a controller configured to control an operation of the transmission. The controller is configured to enter a LURCH control mode when sensing shifting of a shift lever between a D range and an R range during driving to maintain a clutch torque in the transmission, to decrease a vehicle speed by controlling a motor speed, and to shift a gear of the vehicle by changing a motor torque when the vehicle speed reaches a threshold speed.
Claims20
An apparatus for controlling shifting of a vehicle, the apparatus comprising:
- a transmission configured to transmit power generated by a motor to a vehicle wheel;
- and
- a controller configured to control an operation of the transmission, wherein the controller is configured to enter a LURCH control mode when sensing shifting of a shift lever between a D range and an R range during driving to maintain a clutch torque in the transmission, to decrease a vehicle speed by controlling a motor speed, and to shift a gear of the vehicle by changing a motor torque when the vehicle speed reaches a threshold speed.
A method for controlling shifting of a vehicle, the method comprising:
- entering a LURCH control mode when sensing shifting of a shift lever between a D range and an R range during driving;
- maintaining a clutch torque in a transmission when entering the LURCH control mode to decrease a vehicle speed by controlling a motor speed;
- and
- shifting a gear of the vehicle by changing a motor torque when the vehicle speed reaches a threshold speed.
A vehicle comprising:
- a vehicle wheel;
- a motor;
- a transmission configured to transmit power generated by the motor to the vehicle wheel;
- and
- a controller configured to control an operation of the transmission, wherein the controller is configured to enter a LURCH control mode when sensing shifting of a shift lever between a D range and an R range during driving to maintain a clutch torque in the transmission, to decrease a vehicle speed by controlling a motor speed, and to shift a gear of the vehicle by changing a motor torque when the vehicle speed reaches a threshold speed.
