Road junction driving auxiliary device for motor vehicle

Abstract

The invention discloses a road junction driving auxiliary device for a motor vehicle. The road junction driving auxiliary device comprises an identification unit, a distance measuring unit, a speed measuring unit, a central processing unit and an early warning prompting unit, wherein the identification unit is used for collecting information of images in front of the motor vehicle in real time and analyzing and identifying the information, as well as sending related information to the central processing unit when a traffic light and a stop line at a road junction are identified; the distance measuring unit and the speed measuring unit are respectively used for sensing real-time speed of the motor vehicle and a distance between the motor vehicle and the stop line, and feeding the measured data back to the central processing unit; the central processing unit is used for calculating so as to judge whether the motor vehicle can safely pass the road junction or not according to the received data and image information, and corresponding voice prompt can be given by the early warning prompting unit. According to the device, the problem that a driver can not accurately judge whether the motor vehicle can safely pass the road junction or not is solved, and a good human-computer interface is provided, so that the burden of the driver is reduced, the driving safety is improved, and the transportation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of monitoring and early warning, and more specifically relates to an intersection driving assistance device for motor vehicles. Background technique [0002] Drivers at intersections with traffic lights are often frustrated by the inability to accurately judge whether they will be able to cross the stop line before the light turns red. Due to unfamiliarity with the road and insufficient grasp of their own speed and distance, many drivers may choose to speed up after making a prediction that they can pass in time when faced with the above situation, and cause violations or safety accidents. According to statistics from the Ministry of Public Security, in 2012, there were 46,000 intersection traffic accidents involving casualties reported nationwide, resulting in 11,000 deaths and 50,000 injuries, and the situation is becoming increasingly serious. [0003] Another typical situation is, in order not to run a ...
