A smart electric vehicle of the present invention comprises a smart control unit (100, SCU) for realizing a parking assist system (PAS) which promptly responds to a sudden appearance of an obstacle in the rear parking without the driver's operation and a vehicle control unit (11, VCU) for controlling a vehicle at the best level by intercommunicating with a motor control unit (12, MCU), an anti-brake system (20, ABS) and a motor driven power steering (30, MDPS) by a CAN network (200), sending an obstacle approach alarm sound to a human machine interface (HMI) according to the detected obstacle approach distance provided by the SCU (100) when executing the PAS by checking a R gear shift step of a gear shift lever and including an operation algorithm that controls the speed of a motor (13) by sending to the MCU (12) a revival torque value calculated according to the detected obstacle approach distance or controls the speed of the motor (13) by sending to the MCU (12) a limit torque value in which the operation of an accelerator of the driver is not reflected, thereby promptly responding to the sudden appearance of the obstacle in the rear parking by the torque control of the motor (13). |
