Problems solved by technology

After the implementation of the new traffic rules, when many vehicles saw the green light, they didn’t know how long it would take to turn the light yellow. This caused many vehicles to panic when they saw the green light. Even when they reached the stop line, the green light turned yellow and suddenly braked. , causing the vehicle to rear-end

Abstract

The invention provides a signal lamp state detecting method. The signal lamp state detecting method comprises the following steps of acquiring position information of a vehicle and position information of a signal lamp; acquiring the running distance of the vehicle on a road junction with the signal lamp according to the position information of the vehicle and the position information of the signal lamp; acquiring state information and state conversion time of the signal lamp; acquiring running time of the vehicle which runs to the road junction with the signal lamp according to the speed and the running distance of the vehicle; and judging whether the running state of the vehicle is required to be changed or not according to the running time and the state information and the state conversion time of the signal lamp. According to the signal lamp state detecting method in an embodiment, changing conditions of the signal lamp can be accurately controlled, a user can be reminded, so that illegal behaviors or vehicle accidents can be avoided, and the driving safety of the vehicle is improved. The invention also provides a signal lamp state detecting system and a vehicle-mounted control device.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a method for detecting the state of a signal light, a system for detecting the state of a signal light, and a vehicle-mounted control device. Background technique [0002] After the implementation of the new traffic rules in 2013, vehicles that have passed the stop line at the time of the yellow light can continue to pass, and vehicles that do not pass need to stop, but vehicles that passed the yellow light before will not be deducted points. After the implementation of the new traffic rules Finally, when the yellow light is on, vehicles passing the stop line can continue to communicate, and vehicles that fail to pass must stop, and those who run through the yellow light will also be deducted points. After the implementation of the new traffic rules, when many vehicles saw the green light, they did not know how long it would take to turn the light yellow. This caused many ...
