DC bus voltage control
First Claim
1. A method of controlling a vehicle dc bus voltage, the method comprising:
- generating a first parameter based on a demand associated with at least one of a motoring mode operation and a generating mode operation of a motor associated with the vehicle, the demand being indicated in a message received via a dedicated high speed data bus;
generating a second parameter, the second parameter being based on the first parameter and a usage coefficient; and
controlling the vehicle dc bus voltage based on the second parameter.

Abstract
Provided is a method and controller for controlling a vehicle dc bus voltage. The method includes generating a parameter. The parameter is based on a reference dc bus voltage squared. The method includes controlling the vehicle dc bus voltage based on the parameter and a detected dc bus voltage. The method may also include generating another parameter based on a power demand associated with at least one of a motoring mode operation and a generating mode operation of a traction motor associated with the vehicle. The power demand is indicated in a message received via a dedicated high speed data bus. The method includes controlling the vehicle dc bus voltage based on the another parameter.
