Hybrid power commercial vehicle energy management method based on intelligent networking information

The invention relates to the technical field of hybrid electric vehicle control, and discloses a hybrid electric commercial vehicle energy management method based on intelligent network connection information, the current power demand P0 of the whole vehicle is calculated according to the accelerator opening degree and the vehicle speed of a driver, and mode judgment including a pure electric mode, a pure engine mode and a hybrid mode is performed in combination with the SOC of a power battery. The method comprises the following steps: acquiring engine required power PE0 and motor required power PM0, acquiring gradient information and traffic light information through intelligent network connection information, performing fuzzy logic control based on the gradient information and the traffic light information, determining an engine power correction coefficient lambda, and calculating to obtain final engine required power PE1 = PE0 * lambda and final motor required power PM1 = P0-PE1. According to the hybrid po
