Embodiment Construction
[0026] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background or the following detailed description.
[0027] refer to Figure 1 to Figure 2 , is a schematic diagram of a preferred embodiment of a vehicle navigation system provided by the present invention. The navigation system is preferably used in combination with vehicles, such as cars, trucks, engineering vehicles, etc., and is mainly used to prevent traffic accidents such as running a red light. The vehicle-mounted navigation system is used to navigate vehicles near traffic lights and provide information prompts. After the vehicle-mounted navigation system is installed, traffic accidents such as running red lights and the like can be greatly reduced and prevented. The navigation system i...

The invention discloses a vehicle navigation system and a method. The system includes a first detection module, a processing control module, and a second detection module, a wireless communication module and a positioning module that are connected to the processing control module. The first detection module is used for acquiring and sending traffic light remaining work hour information in real time; the wireless communication module is used for receiving the remaining work hour information; the second detection module is used for acquiring the information of distance from the current position of the vehicle to the traffic lights; the positioning module is used for reporting the longitude and latitude position information of the vehicle to the processing control module; and the processing control module calculates the current running speed of the vehicle according to the position information, calculates the running time of the vehicle from the current position to the traffic lights, compares and judges the time difference between the running time and the traffic light remaining work hour information, and sends different prompt information. The system and the method provided by the invention can provide accurate prompt information to a driver and reduce the occurrence of running the red light.
Description
technical field [0001] The invention relates to the field of vehicle navigation, in particular to a vehicle navigation system and method. Background technique [0002] With the rapid popularization of automobiles, intelligent navigation systems based on satellite navigation technology, geographic information system and modern communication technology are playing an increasingly important role in daily life. In the city, traffic violations caused by cars running red lights occur frequently, causing great harm to people's lives and property. In order to reduce the accidents of running red lights, a new type of vehicle navigation terminal that prevents traffic lights from running is needed to solve the problem. [0003] The current navigation terminal can only remind the driver according to the traffic light information stored on its electronic map, and the stored electronic map cannot be updated at all times, and the distance prompted in the navigation is also calculated by GP...
