PREVENTING ELECTRIC VEHICLE BRAKE TORQUE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18123048 titled 'PREVENTING ELECTRIC VEHICLE BRAKE TORQUE
Simplified Explanation:
The patent application describes a controller that activates an engine for vehicle propulsion when the motor is deactivated and the corresponding inverter is disabled. The controller ensures that the motor rotates at a speed based on the vehicle's speed limit, resulting in zero braking torque and zero charging current flow to the traction battery.
- The controller activates the engine for propulsion when the motor is not in use.
- The motor rotates at a speed determined by the vehicle's speed limit.
- The controller commands variable voltage control circuitry to generate a target input voltage for the inverter.
- The target input voltage is based on the vehicle's speed limit to ensure zero braking torque and charging current flow.
Key Features and Innovation:
- Activation of engine for propulsion when motor is deactivated.
- Motor speed controlled based on vehicle speed limit.
- Zero braking torque and charging current flow to traction battery.
- Variable voltage control circuitry for inverter.

Original Abstract Submitted
A controller, while a motor is deactivated and a corresponding inverter is disabled, enables an engine for propulsion of a vehicle such that the motor rotates at a speed due to the propulsion, and commands variable voltage control circuitry to generate a target input voltage for the inverter that is based on a speed limit for the vehicle such that the speed of the motor corresponding to the vehicle travelling results in zero braking torque from the motor and zero charging current flow to a traction battery.
