A vehicle-mounted terminal that strongly displays traffic light information at intersections ahead in real time

Abstract

The invention discloses a vehicle-mounted terminal capable of displaying traffic light information at an intersection ahead in real time, including a core processing unit, a C-V2X communication unit, a 4G communication unit, and a screen display unit. The core processing unit obtains the vehicle's real-time GPS through the C-V2X communication unit Information, intersection number ahead, and roadside traffic light color duration message corresponding to intersection number, and real-time vehicle GPS information, intersection number ahead, and roadside traffic light color duration message corresponding to intersection number are sent to the screen display unit for display ; The 4G communication unit is connected with the core processing unit for providing network services.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a vehicle-mounted terminal capable of displaying traffic light information at an intersection ahead in real time. Background technique [0002] In recent years, with the increase of the number of motor vehicles in our country, the problem of exhaust pollution has become increasingly serious. Argonne Lab conducted a six-month survey on 400 drivers. The research shows that when drivers can predict the situation of the next intersection signal, they will drive more smoothly, reduce the probability of traffic accidents and reduce pollution emissions. And if every car on the planet knew what to expect at the next intersection light, humanity's overall carbon production would drop by 1.3%. [0003] At present, domestic and foreign vehicle-mounted terminals display traffic light information at intersections ahead. Traffic light information cannot be directly sent from the road...

And if every car on the planet knew what to expect at the next intersection light, humanity's overall carbon production would drop by 1.3%

[0003] At present, domestic and foreign vehicle-mounted terminals that display traffic light information at intersections ahead cannot directly send traffic light information to the vehicle-mounted terminal from the roadside, but need to be processed and forwarded by the server, resulting in serious time delay, poor customer experience and practicality, and potential safety hazards
