Abstract: With the continuous promotion of China's "dual carbon" goals and the imminent implementation of fourth stage fuel consumption regulations, energy conservation and emission reduction in the heavy truck industry are urgent. Because hybrid technology has excellent carbon emission and fuel consumption reduction capabilities, it has become an important way for heavy truck to meet the requirements of this regulation. This paper focuses on analyzing the classification and characteristics, application scenarios, current application status, and future trends the configuration of hybrid heavy truck. Analysis shows that the configuration of hybrid heavy truck is mainly divided into three types: series type, parallel type, and hybrid type. Hybrid heavy truck require flexible matching of different hybrid configuration based on operating conditions and application scenarios. At present, the series, parallel and hybrid configuration have been applied in the market in different scenarios, among which the P2 parallel configuration is the mainstream application configuration. In the future, the heavy truck hybrid configuration will be diversified, and the efficient integrated special hybrid assembly will be the focus of the future.
