Novel vehicle control unit suitable for pure electric vehicle

Abstract

The invention discloses a novel vehicle control unit suitable for a pure electric vehicle. The novel vehicle control unit comprises a power source, a main MCU, an auxiliary MCU, a first signal processing circuit, a second signal processing circuit, a communication module and a power driving circuit; the output end of the first signal processing circuit is connected with the input end of the main MCU, the communication module and the power driving circuit are connected with the output end of the main MCU at the same time, the auxiliary MCU is connected with the main MCU to achieve bidirection communication, the second signal processing circuit is connected with the input end of the auxiliary MCU, and the output end of the auxiliary MCU is connected with the input end of the power driving circuit and the input end of the communication module. In the working process, the main MCU collects signals, calculates and processes the signals and then outputs a corresponding control instruction to a controlled mechanism, the auxiliary MCU collects heartbeat signals of the main MCU in real time, and when the main MCU breaks down, the auxiliary MCU executes the collection control process of the main MCU. Problems of a traditional vehicle control unit in resources, loading capacity, safety monitoring and the like are effectively solved.

Description

technical field [0001] The invention relates to a novel vehicle controller suitable for pure electric vehicles, which belongs to the field of vehicle control. Background technique [0002] The vehicle controller is equivalent to the brain of the car. It performs multiple tasks during the driving process of the car. Drive according to driving expectations; (2) communicate reliably with the motor, DC / DC, lithium-ion battery pack, etc., and collect and input the state and output the control command quantity through the CAN bus (and the analog quantity of key information); (3) Receive and process the information of each component, combined with the energy management unit to provide current energy status information; (4) Judgment and storage of system faults, dynamically detect system information, and record faults; Carry out graded protection for the whole vehicle, and cut off the busbar high-voltage system in an emergency; (6) Coordinate and manage other electrical equipment o...
