Claim:
1. A method for controlling a vehicle including a drive motor, comprising: determining, by a controller, whether a braking condition is satisfied based on a vehicle speed, a position of an accelerator pedal, and a position of a brake pedal; determining, by the controller, whether a shifting condition is satisfied when the braking condition is satisfied; operating, by the controller, an inverter to increase torque of the drive motor to be maintained as a predetermined value when the shifting condition is satisfied; operating, by the controller, a first hydraulic pressure actuator to begin release of an off-going element and to begin engagement of the on-coming element when the torque of the drive motor becomes the predetermined value; calculating, by the controller, a friction braking torque that corresponds to a sum of a total braking torque corresponding to total braking amount and a coast regeneration torque eliminated as the torque of the drive motor is maintained as the predetermined value, and operating a second hydraulic pressure actuator to cause a wheel cylinder to generate the friction braking torque; and operating, by the controller, the inverter when a speed of the drive motor is synchronized with a speed that corresponds to a target shift stage to decrease the torque of the drive motor to generate regenerative braking torque that corresponds to a regenerative braking allowance.
