Method and device for preventing mistakenly running red light

Abstract

The invention discloses a method and a device for preventing mistakenly running a red light. The method comprises steps: whether the distance between traffic lights and a target vehicle is smaller than a first threshold and larger than a second threshold is judged; if the distance is smaller than the first threshold and larger than the second threshold, the next red light switching time, the red light lasting time and the red light switching period time broadcasted by the traffic lights are received, and a timer is started, wherein the red light lasting time is the time from when the red light is on to when the red light is off, and the red light switching period time is the time from when the former red light is on to when the next red light is on; whether the distance between the target vehicle and the traffic lights is smaller than a third threshold is judged; if yes, the timer is closed; according to the timing time of the timer, the next red light switching time, the red light lasting time and the red light switching period time, whether the vehicle is currently in a red light period is determined; and if yes, a user is reminded so as to prevent mistaken red light running, wherein the first threshold is larger than the second threshold and the second threshold is larger than the third threshold.

Description

technical field [0001] The invention relates to the field of traffic, in particular to a method and device for preventing red lights from running by mistake. Background technique [0002] At present, judging the situation of traffic lights is mainly determined by the owner's visual inspection. However, there are many problems in this way. Blocked by the large truck in front, the traffic light cannot be seen, causing the owner to accidentally run the red light. These situations, in addition to causing car owners to be deducted points and fines, may also lead to various accidents and endanger the life safety of car owners. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a method and device for preventing mistakenly running a red light, which can actively remind users not to mistakenly run a red light during a red light period. [0004] In the first aspect, the present invention improves a metho...
