Automobile-based automobile incoming prompt system and method

Abstract

The invention discloses an automobile-based automobile incoming prompt system and an automobile-based automobile incoming prompt method. The system comprises a positioning device and a wireless transceiver mounted in an automobile, wherein the positioning device is in communication connection with the wireless transceiver device; the positioning device acquires current position information of the automobile and sends to the wireless transceiver of the automobile; and the wireless transceiver of the automobile sends out the current position and speed information of the automobile and receives data information sent by wireless transceivers of other surrounding automobiles as well as marks automobile incoming situations around the automobile in the positioning device of the automobile or transmits the automobile incoming situations around the automobile to other display devices of the automobile for display. Hence, a driver can clearly know the automobile incoming situations about near roads, particularly under the condition of lower visibility or in curved roads, so that the driver is convenient to take precautionary measures, and therefore, collision accidents with incoming automobiles is effectively reduced and the driving safety is improved.

Description

technical field [0001] The invention relates to the field of automobile electronic equipment, in particular to an automobile-based approaching vehicle prompting system and method. Background technique [0002] With the continuous development of automotive electronics technology, the application of navigation technology in cars has become more mature. The existing car navigation system, its built-in navigation antenna can receive the data information transmitted by the navigation satellites around the earth, combined with the data stored in the car navigation system The electronic map inside can accurately determine the absolute position of the car and mark it on the electronic map. Based on this positioning function, it can also provide the driver with information such as the best driving route and road conditions ahead. [0003] The car navigation system enables the driver to clearly understand the surrounding road conditions from the navigation map, but the surrounding tra...

Problems solved by technology

[0003] The car navigation system enables the driver to clearly understand the surrounding road conditions from the navigation map, but the surrounding traffic conditions cannot be grasped in real time. In the case of poor visibility, or a curve with poor visibility, it often occurs In the event of a collision with an oncoming vehicle

In view of this situation, the method of using infrared scanning sensor to remind the car coming at the curve has been proposed, but its positioning accuracy is not high, and a special infrared scanning reflective sensor needs to be purchased, which increases the complexity of automotive electronic equipment. Easy to market
