Abstract

The invention discloses a power domain control system and an electric vehicle. The power domain control system is applied to the electric vehicle and comprises a whole vehicle energy management system used for carrying out whole vehicle energy control on the electric vehicle, and a whole vehicle energy control content comprises at least one of whole vehicle signal management and diagnosis, whole vehicle electric quantity estimation and battery equalization management; and a power control system is included and is in communication connection with the whole vehicle energy management system and used for carrying out power control on the electric vehicle, and a power control content comprises at least one of main drive motor control, auxiliary drive motor control and gearbox gear shifting control. A technical problem that a power domain control system in the prior art cannot control electronic and electrical parts of the electric vehicle is solved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a power domain control system and the electric vehicle. Background technique [0002] With the continuous development of the electric vehicle industry and the continuous maturity of motor drive, battery management, vehicle control and charging technologies, electric vehicles have become more and more common in people's daily life. But what follows is the continuous increase of on-board controllers, more and more electronic devices, longer and longer lines, various types of signals, and more and more complex vehicle control strategies. Stable operation brings challenges, and also brings pressure on vehicle cost, space and weight. [0003] Starting from the different control domains of the vehicle, there is now the concept of vehicle domain controllers, including cockpit domain, chassis domain and power domain controllers. However, the power domain control system in the prior art...
