Problems solved by technology

[0002] The duration of the red light and the duration of the green light at each traffic light intersection are fixed, and the vehicle can only see the remaining time of the green light or the remaining duration of the red light during driving. The driving vehicle cannot correctly estimate whether the current driving speed can pass the next traffic light. Often when you fail to pass the intersection after speeding up, the green light has turned into a red light. At this time, you have to step on the brakes suddenly. This situation is not safe, but also damages the vehicle

Embodiment 1

[0024] Example 1: If the electronic map ranging module measures the distance between the nearest traffic light and the vehicle in the path planned by the vehicle navigation system on the electronic map data module is 100 meters, the current green light end time is 5 seconds, the next time The turn-on time of the green light is 10 seconds, and the end time of the next green light is 15 seconds. Through the GPS positioning unit, it can be known that the speed limit of the current road section is 80 km / h, then the speed range displayed on the display unit is 72-80 km / h and 24 km / h. ~36 km / h, and the current green light end time is 5 seconds, the next green light turn-on time is 10 seconds, and the next green light end time is 15 seconds, which are displayed on the display unit at the same time.

Embodiment 2

[0025] Example 2: If the distance is 100 meters, the current green light end time is 2 seconds, the next green light turn-on time is 7 seconds, and the next green light end time is 12 seconds. The GPS positioning unit shows that the current road speed limit is 80 km / hour, then the speed range displayed on the display unit is 30-52 km / h. Since the speed obtained by dividing 100 meters by 2 seconds is 180 km / h, which exceeds the limit speed of 80 km / h, the system does not To be considered, the speed range displayed by the display unit is 30-52 km / h, and the current green light end time is 2 seconds, the next green light turn-on time is 7 seconds, and the next green light end time is 12 seconds. superior.

Embodiment 3

[0026] Example 3: If the distance is 100 meters, the current green light end time is 0 seconds, the next green light turn-on time is 5 seconds, and the next green light end time is 20 seconds. The GPS positioning unit shows that the speed limit of the current road section is 80 km / hour, then the speed range displayed on the display unit is 18-72 km / h, and the current green light end time is 0 seconds, the next green light turn-on time is 5 seconds, and the next green light end time is 20 seconds. superior.

Abstract

The invention discloses a system and method for calculating traffic lights based on the Internet of Things, including a vehicle navigation system, the vehicle navigation system includes an electronic map data unit, a GPS positioning unit and a display unit, and the electronic map data unit includes an electronic Map data module, traffic light display state duration statistics module and electronic map distance measurement module, GPS positioning unit measures the nearest traffic light in the route planned by the vehicle navigation system on the electronic map data module through the electronic map distance measurement module The distance data between the vehicle and the vehicle, the distance data is input to the traffic light display state duration statistics module, and the display unit displays the speed range of the vehicle passing the nearest traffic light, and the system calculates the speed required for the traffic lights to be counted Interval, the calculated speed interval is used as a reference for the driver, which can effectively prevent the driver from running a red light and braking suddenly when crossing a traffic light intersection, saving fuel.

Description

technical field [0001] The invention relates to a vehicle navigation system, in particular to a system and method for passing traffic lights in vehicle navigation. Background technique [0002] The red light duration and green light duration of each traffic light intersection are fixed. The vehicle can only see the remaining green light duration or the remaining red light duration during driving. The driving vehicle cannot correctly estimate whether the current driving speed can pass the next traffic light. Often, when accelerating and failing to pass the intersection, the green light has turned into a red light, and you have to slam on the brakes. This situation is not safe and causes damage to the vehicle. Therefore, in order to allow drivers to clearly understand how many yards they can pass the next traffic light when passing through the traffic light intersection, and to pass the traffic light without a try mentality, a traffic light passing computing system based on th...
