Problems solved by technology
[0003] For bumpy and uneven roads, the need to report road condition information is particularly important. The existing technology is relatively complicated and the equipment is expensive to report road condition information through high-precision positioning and calculation of level changes, which is very costly.

Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] The invention is suitable for detection and early warning when a vehicle passes through a "pit". The definition of a "pit" is more than 20cm in diameter and more than 10cm in depth; When it bounces up, the pressure sensor of the main driver will also have an instantaneous pressure change, and the driver will instinctively perform deceleration behavior (if there is no deceleration, there will be speed changes due to friction and pits).

The invention belongs to the technical field of automobiles, and particularly relates to a method and a system for roadblock information detection and early warning in vehicle driving. The system and the method are mainly used for detecting deeper pits on the road surface, and based on the development of the Internet of Vehicles and big data, collected vehicle quantity pressure and vehicle speed information are sent to an operation and maintenance data platform through a vehicle-mounted remote communication terminal, and the operation and maintenance data platform can also synchronize the information to municipal administration, so that the bumpy road surface can be repaired in time, and the maintenance efficiency is improved. And the other path reports vehicle positioning information in real time through a vehicle-mounted wireless terminal GPS module to remind subsequent passing vehicles to avoid, so that the travel of citizens is facilitated, and traffic accidents are reduced.
Description
technical field [0001] The invention belongs to the technical field of automobiles, in particular to a method and system for detecting and warning roadblock information during vehicle driving. Background technique [0002] In many cities, the peripheral roads such as the Fourth Ring Road and the Fifth Ring Road are the only way for heavyweight trucks to come and go. Due to the frequent passage of a large number of trucks on the road surface, the pressure is high, and the renovation is not timely, etc., there are often more serious accidents. Potholes and deep pits on the road often bother the drivers. The speed of passing vehicles on the outer ring is also faster. If the recognition is not timely, there will be serious bumps. Many drivers even temporarily evade and do not pay attention to the left and right. The vehicle has a traffic accident. [0003] For bumpy roads, the need to report road condition information is particularly important. The existing technology is relati...
