When you run into an accident on the road, you can't help changing lanes at will, overtaking other cars, running the yellow light, or swearing. Is it true for you? Well, if it is true, you probably have the "road rage"!

According to a survey, more than 30 million vehicles are running on the road at the same time across China, and 60% of the drivers have "road rage" (driver mania).

Among them, 45% was caused by minor conflicts with other drivers in various unexpected circumstances during driving and failure in expressing their thoughts in time.

30% of the drivers raced mainly because some drivers abused the high beam lights at night. The other 25% of road rage was caused by a variety of other reasons, such as failure in hailing a car, frustration at work, and family conflicts.

All in all, "road rage" is mainly resulted from communication barriers while on the go. In response to the rising "road rage" problems, a smart vehicle-mounted rear window LED display connected to a mobile app is rapidly gaining popularity among car owners.

After the corresponding app was installed, the "negative energy" from driving seats gradually reduced and were replaced with rolling texts on the rear windows of cars, for example, "Use turn signals when overtaking. Nohorn.", "Abuse high beam, amuse your life", and "Thank you for giving away". As communication between drivers becomes timely and smooth, traffic accidents will also be reduced. Under the tide of building a"smart city" and building automotive aftermarket service ecology, the"talking" rear window display has been widely received by the industry.

So, how does this magic tool that drives urban street civilization benefit drivers?

Connection between the mobile app and LED display

Highlights

The full suite of the display consists of a cloud service platform system, an app platform, and a smart display. The LTE Cat.4 seven-mode all-frequency ME3630 module provided byZTE IoT is built in the smart rear window LED display. It connects the display to its app by using the mobile network and allows drivers to send instant messages, including the driver's mood, car conditions, road conditions, weather information, government services, and so on. In this way, instant communication is implemented between cars, drivers' mood has tampered, and quality communication is enhanced between drivers.

Only a vehicle-mounted LED display that can be controlled by a mobile app can be called a smart LED display. When the Internet of Vehicle technology is widely applied to the auto parts industry, the long forgotten vehicle-mounted LEDdisplay is also quietly shifting to the "intelligentization" tide.

SmartVehicle-Mounted Rear Window LED Display

This display is controlled by a mobile app in real time. It gets rid of the inconvenience in installation and text modification and the lack of additional features from conventional vehicle-mounted LED displays. The automatic text sending function opens up a window for drivers to express their thoughts and transforms the idle window of each private car to an economic mobile advertising platform. Car owners can conveniently place an automobile advertisement, whose content can be changed in real time and divided by time and area. In this way, the vehicle-mounted LED display makes money for each driver while on the go.

In the case of sudden accidents, the system is considerate in every detail:

The industrial lightens or disposed on the LED display detects lights of the vehicles behind in real time and automatically turns on text messages so that drivers are relieved from high beams at night.

In the event of sudden braking, the display will blink twice to draw the attention of drivers behind.

In the event of a violent collision, the system will automatically send the preset help request and the location where the accident takes place to the present emergency contact.

Although these functions are small, they can greatly reduce injury caused by accidents and ensure the safety of drivers. The LED display that is originally used only for advertising purposes becomes a "soft insurance" during driving.

Roles of ME3630 in the System

This is not the first time that the ME3630 module is applied on Internet of Vehicle. The performance of ME3630 strictly complies with vehicle mounting standards, which ensures its extensive application in in-vehicle infotainment (IVI) systems,in-vehicle hotspots, and safety protection information collection. In addition, with reliable data transmission and excellent environmental performance, theME3630 demonstrates its robust and optimal performance on Internet of Vehicle.

Operating Principles of the ME3630

The ME3630 module provides full-featured support for 4G and GPS. In network mode, you can send instructions to the LED display by using a mobile app, without needing Bluetooth or Wi-Fi. It is quite convenient. The system also features high-precision GPS services on the platform, through which drivers can view the vehicle's position and trail on the app at any time. Thanks to the GPS, advertising coverage of the LED display is accurate to 5 meters. In addition, real-time analysis and statistics performed by the production company on the advertising distribution provide multi-angle, multi-dimensional, and professional advertising guidance for advertisers.

In March 2017, an in-vehicle Wi-Fi function is added to the LED display based on existing technologies to allow drivers to access the Internet within the car. This is another big step forward in the development of Internet of Vehicles. The ME3630 module with the downlink rate of up to 150 Mbit/s has faster speed and lower delay, ensuring stable and reliable mobile Internet data services in the system.

The operating environment is extremely complex in vehicles. However, the wide-temperature performance of MME3630 has been fully tested under the extreme cold and high temperatures and meets the requirements of vehicle specifications under –40℃ to 85℃. The anti-vibration performance of ME3630 can also meet the standards. Therefore, car owners can use it smoothly anywhere.
