| 摘要 |
A method of controlling an electric vehicle including an internal combustion engine, a battery having a state of charge (SOC) and an open circuit voltage (OCV), is provided. The method includes establishing a system for estimating battery SOC. The system includes an OCV estimation subsystem including an adaptive observer for estimating battery OCV. Estimated battery OCV is related to estimated battery SOC by a nonlinear mapping. An output is generated based on the estimated battery SOC.
