Abstract
An apparatus for shift control in a vehicle includes: a transmission; an acceleration apparatus; and a control circuit electrically connected with the transmission and the acceleration apparatus. The control circuit shifts the transmission from a drive state to a neutral state when an activation condition for coasting is satisfied during travel of the vehicle, and corrects an oil pressure for release of a clutch in the transmission at the time of a kickdown shift, when a driver's input for kickdown is detected through the acceleration apparatus during the coasting.
Claims18
An apparatus for shift control of a vehicle, the apparatus comprising:
- a transmission;
- an acceleration apparatus;
- and
- a control circuit electrically connected with the transmission and the acceleration apparatus,
- wherein the control circuit is configured to:
- shift the transmission from a drive state to a neutral state when an activation condition for coasting is satisfied during travel of the vehicle,
- determine whether a driver's input to the acceleration apparatus is an operation for a kickdown, based on an input pattern for the acceleration apparatus, and
- correct an oil pressure for release of a clutch in the transmission at the time of a kickdown shift, when the driver's input for the kickdown is detected through the acceleration apparatus during the coasting.
