1. A method of implementing a preparation mode for circuit driving of a vehicle,
the method comprising:
acquiring, by a controller, vehicle state information detected by a vehicle state detector while the vehicle is driven on a circuit before racing after entering the circuit, and determining a tire slip rate from a wheel speed and a vehicle speed in the vehicle state information;
determining, by the controller, whether a current vehicle driving state satisfies a preset preparation mode entry condition based on the vehicle state information and the tire slip rate; and
when the current vehicle driving state satisfies the preset preparation mode entry condition, controlling, by the controller, an operation of a warm-up device for warming up a vehicle component that determines driving performance of the vehicle, and warming up the vehicle component.
