Description

Vehicle safety stop positioning system for path detection

Technical field

The invention relates to a vehicle parking, in particular to a vehicle safety parking positioning system for path detection.

Background technique

China began research on driverless cars in the 1980s. The National Defense University of Science and Technology successfully developed the first truly unmanned car in China in 1992. The world's most advanced driverless cars have been tested for nearly half a million kilometers, of which the last 80,000 kilometers were completed without any human intervention. A driverless car is a smart car that senses the road environment through an in-vehicle sensing system, automatically plans driving routes, and controls the vehicle to reach a predetermined target.

It uses the on-board sensor to sense the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained by the perception, so that the vehicle can travel safely and reliably on the road. It integrates many technologies such as automatic control, architecture, artificial intelligence and visual computing. It is a product of computer science, pattern recognition and intelligent control technology. It is also an important indicator to measure the scientific strength and industrial level of a country. The national economy has broad application prospects.

The anti-lock braking system is actually an unmanned system. Although the anti-lock brake requires the driver to operate, the system can still be used as a representative of the driverless system series, as some of the functions of the anti-lock brake system were previously required by the driver to be manually implemented. When an automobile that does not have an anti-lock system is in an emergency brake, the tire will be locked, causing the car to lose control and slip. When driving a car without an anti-lock system, the driver must repeatedly step on the brake pedal to prevent the tire from locking. The anti-lock braking system can do this instead of the driver - and it works better than manual operation. The system monitors the tires, knows when the tires are about to lock up, and reacts in time. And the timing of the reaction is more accurate than the driver. The anti-lock braking system is one of the early technologies that led the automotive industry toward unmanned driving.

Driverless cars are more used for single-point transmission. For example, in the use of public vehicles, unmanned driving cannot be used. The main reason is that there will be problems with getting off at the station; in the research of unmanned vehicles, The experimental areas are all national roads or high-speed road sections with good road conditions. There are also many provincial and county roads in the country. The road conditions of these road sections are not flat, and there will be some uneven places, so the driverless car wants To achieve large-scale promotion in the market, the above difficulties must be overcome.

Summary of the invention
