20120232737 | ELECTRONIC CAR AND CONTROL METHOD THEREOF - The present invention relates to an electronic car and a method of controlling same. More specifically, the present system enters a non-slip mode when a vehicle is on an incline and the brakes are applied making the vehicle come to a stop. When a preset brake sensor value is met, an anti-slip torque value is calculated and when the vehicle begins to move again on the incline, the calculated torque value is applied from the engine in the direction opposite to the slip as the operator moves from the brake pedal to the accelerator pedal. In this way, slippage is prevented during the duration of the switch in pedals. | 09-13-2012 |
