Description

Technical Field

[0002] The invention relates to a control method for realizing automatic driving of a vehicle. Background Art

[0003] At present, the automatic driving control method for vehicles basically relies on a variety of sensors installed on the vehicle itself for environmental perception, including cameras, laser radar (LiDAR), millimeter wave radar, ultrasonic sensors, etc. These sensors are equivalent to the "eyes" and "ears" of the vehicle. For example, Tesla's products and BYD's related products are almost the same. They only use a large number of devices configured on the vehicle body and then use the vehicle's own processing system to calculate data, obtain the vehicle's automatic driving judgment instructions and execute them. This model has greatly increased the repetitive hardware equipment investment, infinite production vehicles and infinitely piled up materials on the vehicle to add automatic driving equipment, and once any of the many equipment in the vehicle fails, it will cause serious consequences. At the same time, the production process causes repeated production of social resources and waste of raw materials. Therefore, it may be necessary to develop a new vehicle automatic driving method that is safer and more reliable and avoids waste of resources and repeated investment as much as possible. Summary of the invention

[0004] By using a highway video laser rangefinder (1001) fixedly installed at a high altitude on the highway, a vehicle driving signal transmitter and receiver (1002) at the control end, and a highway radar wave speedometer (1003), these devices are evenly distributed on the entire highway to ensure comprehensive monitoring and control of all vehicles.

[0005] The installed capacity of the control system hardware is 120% of the maximum number of vehicles that can enter the road to ensure effective control under any circumstances.

[0006] From the moment the vehicle enters the road, it starts to drive by receiving instructions (DT) from the control device through the vehicle-side signal receiver and transmitter (1006) and the vehicle-side automatic driving controller (1007).

[0007] The control end vehicle driving signal transmitter and receiver (1002) and the vehicle end signal transmitter and receiver (1006) in the control system send commands DT and feedback information to each other, ensuring that each command DT can obtain feedback from the receiver.

[0008] Once the interactive signal is terminated, the controlled vehicle will stop immediately to ensure safety.

[0009] The control system also includes a driving system central processor (1004) and a memory (1005) installed at a remote end. These two devices are configured to calculate the vehicle speed, position, distance and other data fed back by the highway video laser rangefinder (1001) and the highway radar wave speedometer (1003).

[0010] The driving system central processor (1004) determines whether these data meet the predetermined conditions based on the calculation results, and sends the corresponding automatic driving instruction DT to the driven vehicle accordingly.

[0011] The driving system central processor (1004) determines the traffic control signal of the highway according to the received traffic signal light data. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a table defining the level of autonomous driving of the autonomous vehicle; Figure 2 is a block diagram illustrating an automatic driving control method according to an embodiment of the present disclosure. DETAILED DESCRIPTION The present invention will be further described with reference to the accompanying drawings and specific embodiments: The control device may include 1001, 1002, 1003 fixedly installed at a high point of the highway and evenly distributed throughout the highway (e.g. Figure 2 ), the control system hardware is installed with 120% of the maximum number of vehicles that can enter this road. From the moment the vehicle enters the road, 1006 and 1007 receive the control device command (DT) to drive. 1002 in the control system and the vehicle-side signal receiver and transmitter 1006 send commands DT and feedback information to each other. Each command DT sent has feedback on the receiving end. Once the interactive signal is terminated, the controlled vehicle stops driving. The control system also includes 1004 and 1005 installed at the remote end. The two devices are configured to calculate whether the speed, position, distance and other data of the driven vehicle fed back by 1001 and 1003 meet the predetermined conditions ( Figure 1 ), and sends the automatic driving instruction DT to the driven vehicle through the calculated data.
