Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a vehicle speed limiting method, a roadside control device, a vehicle and an Internet of Things system. Background Art

[0002] As environmental protection and safety requirements become increasingly stringent, major cities in China have tightened their management of urban construction dump trucks, generally requiring dump trucks to drive at a limited speed in urban areas or operate on designated routes. If they exceed the specified area, the vehicle will be locked to limit the torque.

[0003] However, with the increasing urbanization, the transportation area of ​​​​dump trucks may exceed the scope of the city. For example, the place where the garbage is dumped is located in the suburbs outside the city. The requirements for transportation efficiency for long-distance transportation also increase accordingly. Therefore, it is required that the speed limit of dump trucks be lifted when driving outside the urban area.

[0004] The existing technology uses electronic fences to limit the vehicle's operating area and issue an alarm when it exceeds the operating area. However, for roads with complex transportation conditions or when speed limits are only imposed on certain sections of the road, the electronic fence may not be accurately identified, resulting in erroneous speed limits and the vehicle being locked.
