Design of distributed drive electric vehicle control architecture based on module division

Abstract

Abstract At present, with the deepening of vehicle intelligence and electrification, the logic chaos of the whole vehicle control architecture leads to complex procedures, which cannot adapt to the large-scale, team, and parallel development work, and is not conducive to the later maintenance, upgrading, and platform of the controller. This paper analyzes the types and functions of the vehicle electrical appliances, compiles the vehicle electrical control circuit and CAN (Controller Area Network, CAN) communication network, decouples the control program design from the hardware input signal by reasonably dividing the signal processing flow of the control program, and then divides the vehicle control program into modules to meet the platform-based requirements of the control strategy.
