Embodiment Construction

[0015] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0016] reference figure 1 According to an embodiment of the present disclosure, a driving system 10 is shown. In this example, the system 10 may include an induction motor subsystem 12, and may also include a traction inverter and control system 14 (hereinafter referred to as "inverter system 14"). The inverter system 14 may include an electronic controller 16 and communicate with a processor-controlled vehicle engine control unit (“ECU”) 18. The induction motor subsystem 12 is used at the same time to provide motive power to drive the left wheel 20 and the right wheel 22 of a motor vehicle such as a car or a truck. However, it will be immediately understood that the system 10 is not limited to being used only in automobiles, and in fact is expected to find utility on any type of wheeled vehicle in which the wheels are driven by electric motors and the vehicle needs to be p...

Abstract

The invention relates to a drive system with a limited slip electric differential drive unit. A limited slip electric drive system for a motor vehicle is disclosed. The system uses an induction motorhaving a stator, and first and second rotors disposed for independent rotation within the stator. The rotors are each independently associated with one wheel of the vehicle and are able to slip when the vehicle goes around a turn. A traction inverter and control system monitors angular speeds of the rotors and determines which of the rotors is turning slower than the other, and controls the induction motor in accordance with the rotor having a lower speed so that a torque signal is generated in accordance with the rotor having the lower speed.

Description

Technical field [0001] The present disclosure relates to a drive system for an electric vehicle, and more particularly to a drive system that uses an induction motor to drive a pair of wheels of the vehicle, and wherein the induction motor includes a completely independent and The uncoupled induction rotor is used to independently drive a pair of wheels, without the need for conventional mechanical differential devices. Background technique [0002] This section provides background information related to the present disclosure that may not be prior art. [0003] Currently, electric vehicles such as electric cars can use induction motors to provide propulsion to a pair of wheels. Typically, the front wheels are energized, but in some instances, all four wheels of the vehicle are energized: one motor is used to power the front wheels, and a separate motor is used to power the rear wheels. It is also possible to use a single electric motor to power the rear wheels of the vehicle. I...
