Uncontrolled Generation of Traciton Motors in Hybrid Electric Vehicles
Interior permanent magnet synchronous motor (IPMSM) systems are vulnerable to uncontrolled generation (UCG) when the inverter switches loss their drive signals suddenly during flied weakening high speed operation. At this point, uncontrolled rectifier is composed by freewheel diodes in the inverter, the current comes from the motor through the rectifier, and then charges the battery. This paper...
متن کاملHybrid Electric Vehicles
Hybrid Electric Vehicles HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – A hybrid electrical vehicle (HEV) is a vehicle equipped with either an internal combustion engine (ICE) and an electrical motor powered by electrical batteries. In 1997, Toyota sold in Japan the first modern hybrid electric car, the Toyota Prius. Today’s HEVs are an emerging technology in the automotive market, with manufacture...
متن کاملDirect Yaw Moment Control for Electric and Hybrid Vehicles with Independent Motors
Direct yaw moment control is an effective means to enhance vehicle stability and handling. The majority of the latest direct yaw moment control works employ sliding mode control to generate the target yaw moment. This paper proposes a new sliding mode-based direct yaw moment control method for simultaneous tracking of desired yaw rate and vehicle side-slip for electric and hybrid vehicles equip...
متن کاملSpeed-Sensorless Control of Induction Motors for Electric Vehicles
An electric bus system has been operating in the downtown area of Chattanooga, Tennessee for more than four years. The buses use traditional hard-switched IGBT inverters driving special induction motors with a speed sensor (tachometer) and two embedded fluxsensing windings to provide rotor speed and flux information to the motor controller for implementation of high performance field oriented c...
متن کاملECU Testing for Electric and Hybrid Vehicles
The research conducted by the advanced development and production development departments of automotive OEMs and suppliers show that much work is clearly being done on electrically powered vehicles and related mobility concepts. Some products have already advanced beyond the experimental stage, while many others are prepared to follow shortly. This has put systematic testing of vehicle electron...
