Electric vehicle whole vehicle controller capable of identifying vehicle driving state

Abstract

The invention relates to an electric vehicle whole vehicle controller. An electric vehicle is a movable vehicle which is driven by an electromotor through electric energy. The electric vehicle whole vehicle controller comprises a microprocessor module, a CAN bus communication module, a power module, an analog quantity collecting module, a data quantity collecting module, an analog quantity output module and a switch control output module, wherein the controller identifies a vehicle driving state by processing collected external signals through the microprocessor module. The microprocessor module has the function of fault protection and fault processing after the electric vehicle breaks down, a fault processing unit outputs a control instruction suitable for the running of the current electric vehicle according to the vehicle driving state, and the safe and efficient running of the electric vehicle is ensured through the control instruction.

Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to an electric vehicle complete vehicle controller for identifying the driving state of the vehicle. Background technique [0002] At present, the application of electric vehicles is becoming more and more extensive. The existing vehicle controllers only obtain the control output through simple sensor input, without identifying the driving state of the vehicle. In the control process, the output signals of various states are nested with each other. There is no effective and reasonable distinction, which is inconvenient for the operation and management of the vehicle, and it is inconvenient to distinguish the state for processing after a fault occurs. With the development of science and technology, more and more electronic devices are used in electric vehicles, which can be detected by adding sensors. With multiple signals, the vehicle controller has the function of identifyin...

[0002] At present, the application of electric vehicles is becoming more and more extensive. The existing vehicle controllers only obtain the control output through simple sensor input, without identifying the driving state of the vehicle. In the control process, the output signals of various states are nested with each other. There is no effective and reasonable distinction, which is inconvenient for the operation and management of the vehicle, and it is inconvenient to distinguish the state for processing after a fault occurs. With the development of science and technology, more and more electronic devices are used in electric vehicles, which can be detected by adding sensors. With multiple signals, the vehicle controller has the function of identifying the driving state of the vehicle, decoupling the driving state of the vehicle, and finely dividing the driving state of the vehicle, which can control the electric vehicle more efficiently and safely
