Abstract

The invention discloses a transition system for a high-pressure steering pump and a low-pressure steering pump of a pure electric vehicle and belongs to the technical field of electric automobiles. The transition system comprises a battery management system (BMS), a vehicle controller, a current detection module, a Hall sensor, the high-pressure steering pump and the low-pressure steering pump. Seamless transition between the high-pressure steering pump and the low-pressure steering pump of the pure electric vehicle is achieved, thus the high-pressure steering pump and the low-pressure steering pump can be installed on the pure electric vehicle simultaneously, and the danger brought by the condition that the high-pressure steering pump cannot work is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles. Background technique [0002] At present, domestic pure electric vehicles are developing rapidly. Some electric vehicles use high-pressure steering pumps, and some use low-voltage steering pumps. This is an extremely dangerous thing. [0003] The automobile power steering pump and the steering gear together form the automobile power steering system, which drives the steering wheels of the automobile to realize the steering function of the automobile. There are two types of power steering pumps: high-voltage and low-voltage. The high-voltage input is provided by the power battery through the high-voltage box, and the low-voltage input is provided by the low-voltage small battery. Now pure electric vehicles basically use one of the power steering pumps. Contents of the invention [0004] The purpose of the present invention is to provide a conversion system between the high-pressure s...
