Abstract
A method of parking control for a vehicle equipped with an electric motor independent from a transmission includes calculating external force applied to wheels when predetermined conditions including shifting to a parking (P) stage are satisfied, determining whether a drive shaft fixing apparatus activated according to shifting to the P stage is combined, and controlling the electric motor such that a torque having a magnitude less than the external force is applied to the wheels in a direction opposite to the external force when the drive shaft fixing apparatus is determined to be combined.
Claims20
A method of parking control for a vehicle equipped with an electric motor independent from a transmission, the method comprising:
- calculating external force applied to wheels when predetermined conditions including shifting to a parking (P) stage are satisfied;
- determining whether a drive shaft fixing apparatus activated according to shifting to the P stage is combined;
- and
- controlling the electric motor such that a torque having a magnitude less than the external force is applied to the wheels in a direction opposite to the external force when the drive shaft fixing apparatus is determined to be combined.
A vehicle comprising:
- a transmission;
- an electric motor independent from the transmission;
- a drive shaft fixing apparatus configured to be activated according to shifting to a parking (P) stage;
- and
- a controller configured to:
- calculate external force applied to wheels when predetermined conditions including shifting to the P stage are satisfied and to determine whether the drive shaft fixing apparatus activated according to shifting to the P stage is combined;
- and
- determine a target torque of the electric motor such that a torque having a magnitude less than the external force is applied to the wheels in a direction opposite to the external force when the drive shaft fixing apparatus is determined to be combined.
