Problems solved by technology

At present, automotive products have deficiencies in the following three areas: 1. Navigation, 2. Driving, 3. Anti-theft
The obvious disadvantages of this type of equipment are: 1. It does not have the function of self-made maps; 2. It does not have the function of self-driving cars; 3. It does not have the positioning function relative to the ground and ground objects; 4. The positioning error is proportional to the driving speed
Obviously, this is not a very effective method, so active anti-theft technology has become a new research focus

Embodiment Construction

[0051] Please refer to Fig. 1, intelligent car auxiliary navigation of the present invention and automatic and assistant driving system include:

[0052] A visual position finder 1, which locks the image targets in an appropriate manner and calculates their relative position and relative orientation to the visual position finder 1;

[0053] GPS (Global Satellite Positioning System) Position Finder 2, which can be used as a low-precision slow-speed product or a high-speed fast product, is used to measure the absolute position of the car relative to the reference point of latitude and longitude on the earth;

[0054] The real-time vehicle relative positioning device 3 is used to read the output of the visual positioning device 1 and calculate the position and direction of the vehicle relative to the fixed target on the ground in an appropriate manner. The fixed target on the ground includes: the color on the road surface, the outline on the road surface, Road signs, or buildings...

Abstract

This invention relates to a kind of aptitude automobile assistance guidance and automatism double with assistance driving system. On the foundation of GPS position finder and vision position finder, with a bran-new way to realize automobile absolute positioning, automobile relative positioning, electronic map update and self-command, automobile drive trace plan and automobile automatism double with assistance drive. The invention not only can realize automobile assistance guidance in given or unknown environment, also can realize safe automatic drive or assistance steer. Whereas vehicle outer driver could made choice of a series of automatic drive mission, this invention indirectly supply a kind of active form guard against theft technology, so on occasions of automobile lost, owner could long-distance drive car back.

Description

technical field [0001] The invention relates to motor vehicle navigation technology, in particular to an intelligent car auxiliary navigation and automatic and auxiliary driving system. Background technique [0002] Automobile is an indispensable means of transportation in people's daily work and life. Along with the popularity of private cars, automobiles have become one of the important consumer goods of ordinary people, so the consumer market for automobiles is huge. At present, automotive products have deficiencies in the following three areas: one, navigation, two, driving, and three, anti-theft. The specific instructions are as follows: [0003] Car navigation equipment based on satellite signals is being popularized internationally, but it can only provide absolute positioning relative to a fixed electronic map. This type of equipment mainly includes: inherent electronic map, journey information input, (non-real-time) absolute positioning of the car, simulated trac...
