[0002] At a time when the logistics and transportation industry is booming, heavy trucks, as the main force in long-distance cargo transportation, have a direct impact on logistics efficiency and costs due to their performance. Traditional heavy truck drive systems mostly rely on a single engine or a simple motor combination, and their drawbacks gradually become apparent when faced with complex and diverse operating conditions. For example, in congested urban roads, long periods of idling and low-speed driving cause the engine or motor to operate inefficiently, resulting in a large amount of energy waste; and under different operating conditions such as high-speed driving and climbing, traditional drive systems are difficult to flexibly allocate power and cannot meet the vehicle's precise power needs, resulting in low transportation efficiency and increased vehicle wear and maintenance costs.
