Abstract

The invention relates to the technical field of electric vehicle whole vehicle control simulation, in particular to a pure electric vehicle control strategy simulation verification system and a manufacturing method thereof, comprising a whole vehicle power transmission system simulation model based on CRUISE software and a whole vehicle control strategy simulation model based on MATLABSIMULINK software, the whole vehicle control strategy model is used for simulating a control strategy and outputting the control strategy to the AVL Cruise interface module, and the AVL Cruise interface module receives a simulation data result of the CRUISE Interface module and feeds back and outputs the simulation data result to the whole vehicle control strategy model to form a closed loop for control strategy simulation verification. According to the pure electric vehicle control strategy simulation verification system and the manufacturing method thereof, joint simulation is conducted through MATLABSIMULINK software and CRUISE software, the control strategy is verified through a power transmission system simulation result, a closed-loop system can be formed, the integrity and correctness of the control strategy are effectively improved, and the system has good engineering practical guiding significance.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control simulation technology, in particular to a pure electric vehicle control strategy simulation verification system and a manufacturing method thereof. Background technique [0002] Increasingly serious environmental and energy issues drive the development of automobiles towards clean, efficient and sustainable development. Pure electric vehicles can be considered to have no exhaust emissions, and have the advantages of energy saving, environmental protection, and low cost of use. Therefore, the development of pure electric vehicle projects has attracted more and more attention from the industry. The biggest difference between pure electric vehicles and traditional vehicles is that they use batteries as the energy source and motors as the power output. The technology of controlling the driving of the whole vehicle has become the technical core of pure electric vehicles. In order to a...
