MOTOR DISCONNECT CONTROLS FOR ALL WHEEL DRIVE BATTERY ELECTRIC VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17884029 titled 'MOTOR DISCONNECT CONTROLS FOR ALL WHEEL DRIVE BATTERY ELECTRIC VEHICLE

Simplified Explanation

The abstract describes an electric vehicle with two motors and a processor that can disengage and adjust the torque of one motor to zero before disengaging it completely.

  • The electric vehicle has a first motor, a second motor, and a processor.
  • The processor can select the first motor for disengagement from a first axle.
  • The processor can adjust the torque provided from the first motor to the first axle to zero.
  • The processor can disengage the first motor from the first axle.
  • The processor can reduce the speed of the first motor to zero.

Potential Applications

  • Electric vehicles with improved control over motor disengagement and torque adjustment.
  • Enhanced efficiency in electric vehicle operation.

Problems Solved

  • Improved safety by allowing for controlled disengagement of motors.
  • Increased energy efficiency by optimizing torque delivery.

Benefits

  • Enhanced control over electric vehicle operation.
  • Improved energy efficiency and potentially longer battery life.


Original Abstract Submitted

An electric vehicle, system, and method for operating the vehicle. The electric vehicle has a first motor, a second motor and a processor. The processor is configured to select the first motor for disengagement from a first axle, adjust a torque provided from the first motor to the first axle to zero, disengage the first motor from the first axle, and reduce a speed of the first motor to zero.
