Scenarios
5G vehicle-to-road signal coordination & blind zone early warning
The 5G vehicle-road coordination signal coordination system can realize the priority given by the traffic signal system to the "time" of the zhilian bus, which is mainly reflected in: vehicles with V2X function drive to the traffic light control intersection, and when the road data and signal light real-time status data sent by the 5G roadside unit (RSU) are received, the speed guidance system will give the driver a recommended speed, so that the vehicle can pass through the intersection economically and comfortably, and ensure that the vehicle passes through the traffic lights to the greatest extent.

5G OTA Upgrade & Remote Driving
Combined with 5G large bandwidth, low latency and remote driving technology, remote takeover and real-time control of autonomous vehicles are realized, and problems such as stuck or system failure caused by vehicles due to special roads and other conditions are solved, and the operation delay is within 20ms to ensure that the vehicle is operated without safety personnel. At the same time, it realizes stable and fast remote upgrade (OTA) of intelligent electronic components software functions, and increases the speed by 100 times.
Through the simulation devices such as the steering wheel, throttle, and brake at the cockpit end, the 5G high-bandwidth and low-latency characteristics are used to realize the remote takeover and control of the autonomous vehicle, and improve the scene adaptability of the autonomous vehicle. When the operation scenario exceeds the ODD of the automatic driving system, the cabin safety officer can remotely control the vehicle for safe driving, and when the operating conditions of the automatic driving system are re-met in the operation scenario, the automatic driving can be retaken by the automatic driving vehicle for automatic driving. By using a 5G remote driving system, the vehicle side can reduce the configuration of safety officers, and one cabin safety officer can monitor multiple autonomous vehicles at the same time and take over the problem vehicles as necessary, thereby reducing personnel investment and improving operational efficiency.
