Estimating operation modes for the individual wheel electric drive of the all-wheel drive vehicle with the use of the driving simulator

With the development of the electric drive systems and vehicle on-board power sources the electric transport is becoming more popular, in particular wheeled vehicles with individually driven wheels, while the question of choosing power plants for this type of transport remains unresolved. In the presented article, the authors illustrate an approach to determining the requirements for power plants of such vehicles by an example of a four-wheel drive car equipped with an individual electric wheel drive. The approach is based on the use of the real-time driving simulator allowing the operator to drive the vehicle along typical routes. The typical routes for the driving simulator are generated from the known statistical data on the excitation inputs during the vehicle motion. Thus, the developed driving simulator provides analysis of the vehicle traction motors operation in the conditions most close to the actual ones and collection of the necessary statistical data which can be used for statement of the requirements for new electric machines which would provide their most effective use on the vehicle.
