Vehicle control unit of new energy vehicle

Abstract

The invention belongs to the field of new energy automobile application control equipment, and particularly relates to a vehicle control unit of a new energy automobile. The vehicle control unit comprises a 32-bit embedded Power-architecture MCU chip, a power management module, a digital quantity signal input module, a high-side driving module, a low-side driving module, an analog quantity signalinput module and a CAN network communication module, wherein the power management module, the digital quantity signal input module, the high-side driving module, the low-side driving module, the analog quantity signal input module and the CAN network communication module are communicated with the MCU chip. According to the vehicle control unit of the new energy automobile, through the32-bit microcontroller, processing efficiency is improved, and available resources on the board are increased; rapid prototype development based on a simulink model is supported, simulation and debugging are facilitated, and the program development efficiency of the vehicle control unit is greatly improved; and a 32-bit Power architecture is used, so that function safety is specially realized, the integrity level of ISO26262 ASIL-D is met, and the highest function safety standard suitable for automobile and industrial function safety application is met.

Description

technical field [0001] The invention belongs to the field of new energy vehicle application control equipment, and in particular relates to a new energy vehicle vehicle controller. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. [0003] The vehicle controller is the core control component of the entire vehicle, which is equivalent to the brain of the vehicle. It collects accelerator pedal signals, brake pedal signals and other input signals, and after making corresponding judgments, it controls ...
