Abstract
Nowadays, the world is in a critical period of energy utilization transformation, and the development of the automobile industry is greatly influenced by energy. New energy vehicles represented by electric vehicles are the new direction of the development of the automobile industry in the future. The AVL-Cruise software system has many features, such as simple modeling function, visual design analysis and research, which provides technical support for the simulation projects under complex working conditions of vehicles. Taking the front wheel drive pure electric vehicle as an example, this paper uses AVL_CRUISE software to establish the power system model of electric vehicle, and uses this software to calculate its dynamic performance. The simulation results show that the maximum speed is 178km/h, the 100km acceleration time is 11.59s, and the maximum climbing slope is 30%. The simulation results show that the electric vehicle meets good design requirements. The total energy consumption is 4608KJ. By changing the data such as air resistance coefficient and vehicle quality, the relationship between the dynamic performance and the influencing factors is explored. The corresponding expression is obtained by fitting the data, which provides data support and reference experience for the optimization of electric vehicles.
