Description
Technical Field
[0001] This invention relates to the technical field of unmanned vehicle transmission systems, and specifically to an H-type transmission configuration system for unmanned vehicles. Background Technology
[0002] The H-type drivetrain configuration is a vehicle power transmission system layout characterized by multiple drive units arranged in an "H" shape, achieving efficient power transmission and flexible control. This configuration is commonly used in unmanned vehicles to meet power distribution requirements under complex operating conditions. The H-type drivetrain configuration is named "H-type" because its power transmission structure has an "H" shape in its system layout. It typically includes front and rear driveshafts or electric drive modules, as well as a central connecting module, such as a transfer case or power management unit. The core purpose of this structure is to achieve flexible distribution of power output between the front and rear of the vehicle, and combined with intelligent control, to optimize transmission efficiency and stability.
[0003] With the rapid development of autonomous driving technology, more and more driverless vehicles are adopting complex transmission systems to achieve efficient and stable driving performance. In traditional vehicle transmission systems, a single transmission path or a simple multi-transmission path design is usually used. However, under complex road and environmental conditions, traditional transmission systems often cannot respond efficiently to changes in road conditions, resulting in insufficient energy efficiency and slow vehicle response speed.
[0004] Many unmanned vehicle transmission configurations have been developed. Through extensive research and reference, we found that existing unmanned vehicle transmission configurations, such as those disclosed in publication numbers CN112874255A and CN105235467A, generally include: a transmission configuration body, a data acquisition terminal, and an analysis and control terminal. The transmission configuration body supports the unmanned vehicle and enables transmission; the data acquisition terminal acquires the unmanned vehicle's operating status; and the analysis and control terminal analyzes the unmanned vehicle's operating status and parameters to generate control commands. Because the operation process of these unmanned vehicle transmission configurations is relatively simple and lacks efficiency and safety analysis, unmanned vehicles are prone to malfunctions and accidents during operation, resulting in decreased transmission stability.
