Title:
HYBRID VEHICLE AND POWER GENERATION CONTROL METHOD AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/062883
Kind Code:
A1
Abstract:
Disclosed are a hybrid vehicle and a power generation control method and device thereof. The control method comprises: acquiring an inclination, an accelerator depression amount, and a power of a power consumer of the hybrid vehicle to determine a target power consumption level of the hybrid vehicle (S1); acquiring an SOC value and an SOC balance point of a traction battery of the hybrid vehicle to determine the required power generation level of the hybrid vehicle (S2); acquiring the maximum allowed power generation power of a secondary motor of the hybrid vehicle, a power generation output power of an engine in a preset optimal economic region, and an allowed charging power of the traction battery in order to determine a power generation capacity level of the hybrid vehicle (S3); and determining a final power generation level of the hybrid vehicle in accordance with the target power consumption level, the required power generation level and the power generation capacity level, and controlling the power generation of the hybrid vehicle according to the final power generation level (S4). Therefore, control over the power generation is combined with the power consumption situation, the power protection capability of the entire vehicle is improved, and the user experience is improved.
