On electric vehicle traction drives, Induction motor Field Oriented Control is widely adopted.
There are two winding methods for the interior permanent-magnet synchronous motor for vehicle traction: concentrated winding and distributed winding.
The battery pack is the main power source whereas the fuel cell is considered as a range extender that cannot sustain alone the vehicle traction power.
According to the comprehensive modal emission model, the emission of carbon is dependent on three modules each showing a component of energy consumer for vehicle traction: (1) speed module, (2) weight module, (3) engine module.
The research achievements filled the technical gaps in this field of China, totally reached the international advanced level, in which the vehicle traction, disk brake, a new car ATP, sliding switches and other core technology reached the international leading level.
The simulation results show that the proposed control algorithm provides very good acceleration slip regulation in a vehicle traction maneuver on low friction coefficient surfaces when compared with that without the controller.
Vehicle traction control including solutions for engine control, electronic differentials, powertrain and driveline control in general [41, 42, 43], Control of lateral vehicle dynamics, in particular, in terms of yaw rate and vehicle sideslip control [44, 45, 46, 47, 48], Steering control including solutions for electric power steering; active front and rear steering [49, 50, 51].
Their tracks were long, which gave the vehicles good traction but reduced their speed.
Moreover, under common road conditions for heavy commercial vehicles, the traction force can increase up to 13.4 15.6%.
"It took us a long time to rid ourselves of total dependence on oil and carbon fuels, now renewable energy, LED lighting and electric vehicles have traction," Swanson said.
