Abstract

The invention discloses a power domain controller system, which comprises a vehicle control unit and a battery management system, wherein the battery management system comprises a low-voltage microcontroller, and the vehicle control unit is connected with the low-voltage microcontroller and is used for carrying out fault monitoring on the low-voltage microcontroller; and after the fault is removed, the low-voltage microcontroller generates a fault removal signal and sends the fault removal signal to the vehicle control unit. Core functions of the vehicle control unit, the battery management system and the motor controller are integrated into a power domain control system, the crossing of the power system controller from three traditional controllers to one single controller is realized, the hardware cost of the power system controller is effectively reduced, and the problems of numerous controllers and complex whole control system in the existing electric automobile are solved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle controllers, and in particular relates to a power domain controller system. Background technique [0002] With the continuous popularization of new energy vehicles and the gradual decline of subsidies, electric vehicles, which use electric energy as a power source, are also facing increasingly severe cost pressures, and the core technology and cost of electric vehicles are concentrated in the controller. Therefore, the cost pressure is gradually decomposed to each controller of the vehicle. In order to ensure the driving functions and service life of electric vehicles and reduce the production cost of enterprises, it is necessary to improve the hardware cost of the controller, and reduce the cost of the controller as much as possible under the premise of ensuring functional safety requirements. [0003] In the current market, the automotive electronic and electrical architecture has alwa...
