The invention belongs to the field of automobile parking systems, and particularly relates to an automatic parking system for a new energy commercial vehicle and a control method. The service braking unit is connected with the control unit; and the parking braking unit is connected with the control unit, and when the service braking time exceeds a set execution time threshold value, the control unit controls the parking braking unit to achieve automatic parking braking. The control method comprises the following steps that the service braking unit is controlled to conduct automatic service braking; and when the service braking time exceeds a set execution time threshold value, the service braking unit is not controlled to perform automatic service braking, the parking braking unit is controlled to realize automatic parking braking, meanwhile, the automatic service braking is relieved, and after the parking braking is relieved, the auxiliary hill starting is realized by combining the control of the driving motor. The system is simple in structure and method, high in reliability and low in cost, can be widely popularized on new energy commercial vehicles, and becomes standard configuration of the vehicles.
