Abstract:
1. A control method for shortening a start time of an in-wheel motor vehicle comprising: comparing, by a vehicle control unit (VCU), a DC-link voltage in an inverter for driving a driving motor with a first reference value in a state in which the connection between a main battery and a vehicle system is released; checking, by the VCU, a remaining voltage in a vehicle driving system and comparing the checked remaining voltage with a second reference value, when the DC-link voltage in the inverter is no less than the first reference value; removing the remaining voltage by operating an electric load in the vehicle to consume remaining electricity in the vehicle system, when the remaining voltage is no less than the second reference value; and connecting the main battery to the vehicle system by turning on a pre-charge relay and a main relay, wherein the remaining voltage in the vehicle driving system is a voltage at an input or output terminal of a motor control unit (MCU) for controlling the driving motor in the vehicle driving system.
