The invention provides a self-balancing vehicle. The self-balancing vehicle comprises a vehicle body, two vehicle wheels, a manipulation rod component and a drive control unit, wherein the drive control unit controls rotation of the two vehicle wheels so as to control the advance speed and direction of the self-balancing vehicle. The self-balancing vehicle further comprises a safety device, wherein the safety device comprises at least one swing arm, a first end of each swing arm is connected with the vehicle body, a rotatable idler wheel is arranged at a second end of each swing arm, each swing arm can move between a retract position and at least one advance position, each swing arm does limit pitching angles of the vehicle body relatively to the horizontal plane at the retract position, each rotatable idler wheel keeps away from the vehicle wheels and deviates from the ground for a preset distance at the at least one advance position, and therefore the pitching angles of the vehicle body relatively to the horizontal plane are limited in a preset range, and then the maximum advance speed of the self-balancing vehicle is limited. When each rotatable idler wheel is landed, each rotatable idler wheel and the two vehicle wheels form a triangular support structure, the vehicle body can stably stand, and a safe protection function is achieved. The invention further provides a safety control method of the self-balancing vehicle.
