Abstract

An embodiment of the invention provides a vacuum booster system of an electric automobile and a pressure measurement method of the system. The system mainly includes that a relative pressure sensor and an absolute pressure sensor are oppositely arranged on a vacuum booster, sensor signals of the relative pressure sensor and the absolute pressure sensor are connected into a vehicle control unit through cables, and the relative pressure sensor and the absolute pressure sensor are used for measuring absolute pressure and atmospheric pressure in the vacuum booster system. According to the vacuum booster system of the electric automobile and the pressure measurement method of the system, the relative pressure sensor and the absolute pressure sensor are oppositely arranged on the vacuum booster, and the sensor signals are connected into the vehicle control unit, so that the absolute pressure and atmospheric pressure in the vacuum booster system of the electric automobile can be accurately and effectively measured, and by the aid of the redundant design of double sensors, the safety and reliability of the vacuum booster system of the electric automobile can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vacuum booster system of an electric vehicle and a pressure measurement method thereof. Background technique [0002] Pure electric vehicles are representatives of new energy vehicles. Since pure electric vehicles do not have a vacuum source provided by the engine assembly, an electric vacuum booster system needs to be added. [0003] Considering the influence of atmospheric pressure on the vacuum booster system, as well as the safety and importance of the vacuum booster system itself, it is necessary to effectively measure the external atmospheric pressure. In the prior art, there is no solution for accurately and effectively measuring the absolute pressure in the vacuum booster system of the electric vehicle and the external atmospheric pressure. Contents of the invention [0004] Embodiments of the present invention provide a vacuum booster system of an electric...
