Abstract

The invention discloses a vehicle power supply safety optimization method. The vehicle power supply safety optimization method comprises the following steps of: judging whether emergency switches are disconnected or not; if yes, grounding the D+ terminal of a generator; and disconnecting a battery. Thus, according to the vehicle power supply safety optimization method disclosed by the invention, if the emergency switches are judged to be disconnected, the D+ terminal of the generator is grounded, and the generator stops running due to the grounding of an excitation circuit, so that the generator stops working, and then the battery is disconnected; and on one hand, the D+ terminal of the generator is grounded firstly, and the generator stops running due to the grounding of the excitation circuit, so that the current generated by the generator due to inertia cannot enter a vehicle circuit, the situation that the vehicle circuit is impacted by a back electromotive force due to only disconnection of the battery is avoided, an electric arc phenomenon is avoided, and the power supply safety of a vehicle is improved. The invention further discloses a vehicle power supply safety optimization device and an automobile comprising the same, which have the same technical effects as those of the vehicle power supply safety optimization method.

Description

technical field [0001] The invention relates to the technical field of vehicle power supply safety, in particular to a method and device for optimizing vehicle power supply safety. Background technique [0002] With the continuous and rapid development of my country's economy and society, the rigid demand for car purchases is strong, and the car ownership continues to show a rapid growth trend. In 2015, the number of newly registered cars reached 23.85 million, with a net increase of 17.81 million vehicles, both of which are the highest in history. The ratio of automobiles to motor vehicles has increased rapidly. In the past five years, the ratio of automobiles to motor vehicles has increased from 47.06% to 61.82%. The motorized travel mode of the masses has undergone a transformation from motorcycles to automobiles, and the traffic structure has undergone fundamental changes. The rapid increase in the number of motor vehicles and drivers brings convenience to people's produ...
