TRACTION ASSISTANCE SYSTEM FOR FOUR WHEEL DRIVE ELECTRIC VEHICLE
2015
The increasing prospect of electric vehicles has led to many different control schemes to be applied on the driving system. The Front and rear wheel drive electric vehicles are being developed as the next generation electric vehicle with ideal characteristics of driving performance of all types of propulsion systems and various driving conditions. By analysing the power distribution of the given driving cycle, the energy efficiency of the traction machine over the driving cycle can be characterized against a number of driving conditions and the control optimization can be carried out with respect to the conditions. The main objective is to analyse the condition of the driving mechanism and automatically convert the driving (2/4 wheel drive) mechanism during starting time, slope conditions, long driving and braking times. Also the parameters during various driving modes such as 2 wheel modes, 4 wheel modes and automatic drive changing modes are analysed and compared. The analysis and control actions are taken in LabVIEW software automatically and the data for various driving modes are recorded and the analyses for power consumption, efficiency, driving distance, etc., are validated.
