Description

Technical Field

[0001] This utility model relates to the field of car chassis, and in particular to a car chassis that combines manned and unmanned operation. Background Technology

[0002] With the continuous application of vehicle intelligence technology, vehicles capable of switching between human-driven and driverless modes have been developed. These vehicles combine autonomous driving technology with traditional driving methods, aiming to improve traffic efficiency, safety, and driving experience. A car chassis is an essential component in the construction of such vehicles.

[0003] To enable both manned and unmanned driving functions, existing car chassis typically separate the driving space from the space for intelligent driving equipment. This allows for the installation of manned and unmanned driving devices and structures within the corresponding areas. However, when the vehicle travels on muddy roads, mud adheres to the sides of the wheels. If this mud is not removed promptly, it can cause the wheels to slip on hard surfaces, affecting safe driving. Therefore, this solution proposes a car chassis that combines manned and unmanned driving capabilities to address these issues. Utility Model Content
