Embodiment Construction

[0029] The vehicle controller of the present invention includes vehicle CAN network topology optimization, vehicle body state monitoring, driver intention analysis, energy state monitoring, fault alarm diagnosis, and vehicle operation guarantee;

[0030] In conjunction with the accompanying drawings, the specific description is as follows:

[0031] exist figure 1 In, the communication between the vehicle controller and some peripheral devices is introduced.

[0032] exist figure 2 Among them, the electric vehicle vehicle control system adopts the CAN bus communication method, and the vehicle controller is used as the controller for the control strategy and also as the CAN communication gateway to connect the battery management system, motor controller and other electronic control units.

[0033] exist image 3 Among them, the vehicle CAN network is composed of 3 independent CAN buses, which are respectively designated as CAN1 vehicle status bus, with a communication rate o...

Abstract

The invention relates to a vehicle control unit for a pure electric vehicle. A vehicle control board with an ARM9S3C2440 master module and multi-site CAN (Controller Area Network) bus communication are adopted, and a power management system and a motor controller are combined to form a vehicle CAN control communication network. The vehicle body status monitoring, driver intention analysis, energy status monitoring, fault alarm monitoring, and vehicle running guarantee functions and the like are realized. The control unit is integrated with the status information of various parts such as an acceleration pedal, a brake pedal, a vehicle-mounted energy source and a driving motor to decide the currently taken control strategy; the warning forecast of the fault in the movement process of the vehicle is carried out; and when the vehicle decelerates and brakes, the whole power and an energy storage system work in an energy feedback status by control instructions. Meanwhile, the multi-site CAN bus technology is used, so that the stability of the whole control unit is substantially improved, and the cost is effectively saved.

Description

technical field [0001] The invention relates to a vehicle controller for a vehicle, in particular to a vehicle controller for a pure electric vehicle. Background technique [0002] In order to meet the needs of production and life, human beings invented the automobile in 1886. However, automobiles have brought convenience, comfort and fast modern life to human beings, but they have also brought increasingly serious environmental pollution and energy crisis. Especially in the past ten years, environmental pollution and energy crisis have become two major problems facing the development of countries all over the world. [0003] A pure electric vehicle is a "zero-emission" vehicle that saves petroleum energy and has no pollution. Electric vehicles include fuel cell vehicles, hybrid vehicles and pure electric vehicles, which are the most mainstream new energy technologies in the world. Compared with the traditional ones, electric vehicles have the advantages of high ef...
