With the rapid development of artificial intelligence, big data, and other technologies, the vast market demand has prompted the research and application of car networking-related products to land, making the whole automotive industry develop in the direction of safety, comfort, and green. Remote intelligent driving technology is a significant development direction in automotive networking and has many application prospects. In complex environments, drivers can use the remote control to command their vehicles, thus enabling safe and reliable driving on rugged roads and introducing manual decision-making on challenging roads, thereby reducing traffic accidents and casualties.

In response to this demand, WiMi has developed a 5G remote driving integrated control system for driverless vehicles and obtained the software copyright. The system realizes a comprehensive network link between the car and the cloud platform, the vehicle and the vehicle, the vehicle and the road, the vehicle and the people, and the interior of the car through a new generation of information and communication technology, mainly realizing the “triple network integration,” i.e., the integration of the in-vehicle network, the inter-vehicle network, and the in-vehicle mobile internet. It fully uses 5G’s low latency, high bandwidth, and high-reliability features. It integrates 5G communication, vehicle-road-cloud collaboration, cloud computing, and automatic control technologies to ensure close cooperation and information interaction between vehicles and systems, and remote control of vehicles by remote drivers, solving the problem of complex operation under dangerous conditions and providing the safe operation of autonomous driving. Through 5G technology, the system can achieve large bandwidth transmission of voice and video data and low latency, highly reliable transmission of remote control commands and strong support for remote intelligent driving operations.

WiMi’s driverless 5G remote driving integrated control system provides omnidirectional monitoring and intelligent remote control with three core components:
- driving data interaction and control,
- 5G network transmission, and
- integrated control.

The controller and the vehicle CAN interface mainly accomplish driving data interaction and control. The remote cockpit system can send control signals, vehicle status information, positioning information, radar information, cameras, and other information. For example, the ECU transmits the vehicle-side information on vehicle speed, motor speed, unique steering axis angles, and additional information to the vehicle-integrated control via the CAN interface, which is analyzed and encapsulated by the vehicle-integrated control and transmitted to the system in the first instance via switches, CPE and other network devices and visualized.

5G network transmission is achieved mainly by the 5G network and QOS technology. RSU, MEC, private lines, and other essential network transmission equipment can transmit data to the platform and intelligent cockpit. The key indicators of the remote innovative driving system are latency and rate, which are related to the layout structure of the network. The system contains a 5G base station + 5G core network, 5G base station + MEC, 5G base station + leased line, etc. Different network architectures will provide different rate and latency guarantees, and other network architectures will be selected according to the user’s needs.

The integrated control mainly consists of a platform and an intelligent cockpit. The platform is responsible for the maintenance and management of data and provides a visual display; the intelligent cockpit collects the user’s driving data and displays images of all aspects of the vehicle, such as the front, left, right, panorama, and interior. The data will be presented on the large screen in real time for the driver to judge the car, road conditions, etc. The cockpit will send all the driver’s movements to the vehicle end to achieve the monitoring of remote traffic.

To achieve autonomous driving, vehicle-road collaboration must be completed in addition to the hardware conditions in place. This requires vehicles, traffic facilities such as street lights, roads, traffic signs, and even buildings to be connected to the internet. WiMi will continue to conduct research on vehicle sensing fusion technology and the optimization of algorithms, computing power, deep learning, and other computing platforms, with a focus on the development and application of technologies such as 5G and satellite positioning and navigation systems, to lead the industry in technological upgrading in the field of autonomous driving.
