Modelling of an Electric Vehicle for Tractive Force Calculation Along With Factors Affecting the Total Tractive Power and Energy Demand

摘要

In the automotive industry from the past years, the trend has been towards more complicated electronic control system. The new approach for vehicle design has to be multidisciplinary. Developing a simulation model for the vehicle design with an optimal accuracy is a challenging task where only the driving cycles and the vehicle specifications are the inputs for the simulation. In this paper presents an equation-based design approach for the vehicle design to calculate the total tractive power and energy required for propulsion. The output result of this study is constructive to design a new vehicle because it allows you to a trade-off between the range and power source required for particular vehicle either conventional vehicle, electric vehicle and hybrid vehicle. The main goal for this paper is to investigate and quantify the relationship between the dynamic vehicle parameters and its energy consumption along with highlights the three standard drive cycles used for the simulation of the middle-size sport-utility. This proposed model is sufficient to understand the effect of all the resistance forces acting on the vehicle such as wind resistance force, rolling resistance force, grade resistance force, acceleration resistance force and these resistance forces having direct relationship with the vehicle parameters as vehicle mass, frontal area, air density, drag coefficient, rolling resistance coefficient and road angle etc. The circuit is built in the SIMULINK/MATLAB for the verification of the vehicle design. The US06 standard drive cycle is given to the model as input to investigate the performance of the vehicle design under the more real and practical conditions.
