Abstract: The present disclosure provides a vehicle, a start control method for the vehicle, and a start control system of the vehicle. The method includes: when a door of the vehicle is in an open state, determining a position of a key; when the key is in the vehicle, controlling a first high-voltage module group of the vehicle to perform power on; when the door of the vehicle is changed from the open state to a closed state, determining the position of the key and detecting a state of a brake pedal of the vehicle; and when the brake pedal of the vehicle is depressed and the key is in the vehicle, controlling, according to a start instruction, a second high-voltage module group of the vehicle to perform power on, so that the first high-voltage module group is controlled, by using a time for a user to open and close the door, in advance, to perform power on, reducing a time for the user to start the vehicle after inputting a start instruction, effectively shortening a time for the user to wait for the vehicle to start, and improving user experience.
