Apparatus and method for controlling vehicle having motor

摘要

An apparatus for controlling a vehicle having a motor is provided and includes a driving information sensor that senses driving information of the vehicle including an open value of an APS, an open value of a BPS, a driving wheel speed, a non-driving wheel speed, external temperature, battery temperature, a vehicle speed, and a shift stage. A driving motor generates a driving force and is operated as a power generator when the vehicle coasts to generate electric energy. An ABS that adjusts a braking force applied to a driving wheel. A controller changes a coast regeneration torque subject to regenerative braking by the driving motor when the vehicle is coasting, based on a difference between a driving wheel speed and a non-driving wheel speed, correction temperature determined based on the external temperature and the battery temperature, a friction coefficient of a road, and an operation condition of the ABS.

1. An apparatus for controlling a vehicle having a motor, comprising:
a driving information sensing unit configured to sense driving information of the vehicle including an open value of an accelerator position sensor (APS), an open value of a brake position sensor (BPS), a speed of a driving wheel, a speed of a non-driving wheel, external temperature, battery temperature, a vehicle speed, and a shift stage; a driving motor configured to generate a driving force and operated as a power generator when the vehicle is coasting to generate electric energy; an antilock brake system (ABS) configured to adjust a braking force applied to a driving wheel; and a controller configured to change a coast regeneration torque subject to regenerative braking by the driving motor when the vehicle is coasting, based on a difference between a speed of a driving wheel and a speed of a non-driving wheel sensed by the driving information sensing unit, correction temperature determined based on the external temperature and the battery temperature, a friction coefficient of a road, and an operation condition of the ABS.
