AI Technical Summary
Existing technologies only use ambient temperature as the main adjustment parameter for SOC, without considering the vehicle's own state and battery SOC fluctuations. This leads to repeated fluctuations in the electrical balance point, affecting the user's driving experience and failing to meet the requirements for pure electric range.
By acquiring the electric balance parameters of hybrid vehicles, such as the sleep time of the battery management system, the ambient temperature outside the vehicle, and the actual state of charge of the battery, the electric balance state of charge is estimated, and the optimal driving mode is determined, including pure electric mode, hybrid mode and pure fuel mode. The mode is switched according to the electric balance state of charge to meet the driving needs of the vehicle.
It improves the intelligence level of hybrid vehicles, ensures more accurate determination of the battery balance point, avoids repeated fluctuations in the battery balance point, enhances the user's driving experience, and meets the vehicle's driving needs.
