Electric whole passenger vehicle control system based on programmable logic controller technology

Abstract

The invention discloses an electric whole passenger vehicle control system based on a programmable logic controller technology. The electric whole passenger vehicle control system comprises a programmable control logic operation unit and a plurality of executing units. The programmable control logic operation unit executes PLC commands established by a whole vehicle factory, and the executing units are adopted to control the electric whole passenger vehicle control system to be externally arranged. The electric whole passenger vehicle control system has the advantages that by means of the electric whole passenger vehicle control system based on the programmable logic controller technology, the whole vehicle factory is made to conduct programming and testing according to a whole vehicle control strategy of the whole vehicle factory, one control system is suitable for vehicles of different models or functions, the whole vehicle factory only needs to conduct simple modification on a PLC program to meet the requirement, and the system is good in transplantation and universality.

Description

technical field [0001] The invention relates to a whole vehicle control system of an electric passenger car, in particular to a whole vehicle control system of an electric passenger car based on programmable controller technology. Background technique [0002] In response to the new energy vehicle strategy proposed by the state and the market development needs, various domestic OEMs have successively launched their own electric buses. Different from conventional cars, the power of electric buses comes from batteries. OEMs need vehicle controllers to distribute energy to each unit in the vehicle according to the battery power, and manage the charging and discharging of batteries. Different models have different control strategies. At present, various OEMs customize controllers from institutions of higher learning, scientific research institutions, technology companies, etc. As a result, one controller can only implement one vehicle control strategy, and the system has poor po...
