Description

Technical Field

[0001] The invention relates to the technical field of highway transportation, and in particular to an expressway. Background Art

[0002] On January 29, 1886, German Karl Benz obtained patent No. DRP37435 for his "car equipped with a gasoline engine". This day is recognized by the world as the birthday of the car. When cars first appeared, there were many road participants on the existing roads at that time, including horse-drawn carriages, rickshaws, pedestrians, etc. The speed of horse-drawn carriages was about 20km / h, and the speed of rickshaws and pedestrians was even slower. In addition, there were many intersections, and the road speed was slow. In the early 20th century, the maximum speed of cars could reach more than 100km / h, but the speed performance of cars on old roads could not be fully utilized. In 1932, Adenauer, the mayor of Cologne, Germany, invented and built the world's first highway, the "Bonn-Cologne Highway". The highway greatly increased the road speed by reducing the types of participants (only motor vehicles such as cars pass, and horse-drawn carriages, rickshaws, pedestrians, etc. are excluded) and eliminating intersections. It increased from about 20km / h on ordinary roads to more than 100km / h on highways. Expressways have become the "artery" of economic development. Since the completion and opening of China's first expressway, the Shanghai-Jiaxing Expressway, in 1988, China has built nearly 180,000 kilometers of expressways in more than 30 years. China's ordinary roads (non-expressways) have a mileage of more than 5 million kilometers, and the proportion of expressways in traffic is still relatively low. There are both small passenger cars (generally limited to 120km / h) and large vehicles such as buses and trucks (generally limited to 100km / h) on the expressway. The mixing of vehicles of different speed levels leads to a slower overall speed. In addition, the different driving skills and driving styles of different drivers also lead to a slower overall speed. With the maturity of power lithium battery technology, electric drive vehicles are rapidly popularized, and the current penetration rate has exceeded 30%. However, when electric vehicles are driving at high speeds, they consume a lot of power and need to be charged frequently. However, the number of charging equipment in highway service areas is limited and the charging speed is slow, which seriously restricts electric vehicles from traveling long distances on highways.

[0003] Greenhouse gas emissions such as carbon dioxide cause global warming. In order to cope with this climate crisis, many countries have proposed a timetable for "carbon peak and carbon neutrality". It is an inevitable trend for electric vehicles with zero carbon emissions to completely replace fuel vehicles. At the same time, autonomous driving technology is developing rapidly, and autonomous driving on closed roads such as highways has become a relatively mature technology. Therefore, it is necessary to invent a new type of highway to match new technologies such as electric vehicles and autonomous driving to achieve higher speed and more efficient road traffic. Summary of the invention

[0004] The embodiments of the present application provide a highway and a highway traffic system, which can achieve higher travel speed and travel efficiency and longer mileage for electric-driven vehicles, have low construction costs, and are suitable for large-scale construction.

[0005] In a first aspect, an embodiment of the present application provides a highway, including: a highway entrance, a highway driving lane, and a highway exit. The highway entrance includes a vehicle information acquisition and processing device and an entrance opening and closing device.

[0006] The vehicle information acquisition and processing device acquires and processes the information of the vehicle arriving at the entrance of the expressway, determines whether the vehicle's maximum continuous driving speed, the vehicle's automatic driving function, the vehicle's power unit type, and the vehicle's power supply device meet the requirements of the expressway lane, and verifies whether the automatic driving function is in working condition.

[0007] If the vehicle's maximum sustained speed is greater than or equal to the rated maximum speed of the highway lane, and the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control, and the vehicle's power unit type is electric drive, and the vehicle has a power supply device that matches the highway lane power supply device, and the vehicle's automatic driving function is in operation, then the vehicle information processing result is "pass", the entrance opening and closing device opens, and the vehicle is allowed to enter the highway.

[0008] If the vehicle's maximum sustained speed is less than the rated maximum speed of the highway lane, or the vehicle does not have the automatic driving function to autonomously complete driving from any starting point to any end point on the highway according to program control, or the vehicle's power unit type is not electric drive, or the vehicle does not have a power supply device that matches the highway lane power supply device, or the vehicle's automatic driving function is not in working condition, the vehicle information processing result is "fail", the entrance opening and closing device remains closed, and the vehicle is not allowed to enter the highway.

[0009] A power supply device is installed on the driving lane of the highway, and the power supply device includes a first conductor and a second conductor. The first conductor and the second conductor are respectively connected to the positive pole and the negative pole of the power supply. The first conductor and the second conductor are respectively in contact with the positive pole and the negative pole of the vehicle power supply device and supply power to the moving vehicle.

[0010] In this embodiment, since the highway entrance will obtain vehicle information and analyze and process the corresponding technical characteristics, only electric-drive vehicles that can drive automatically on the highway and whose driving speed meets the requirements are allowed to travel on the road. The highway can supply power to the moving vehicles in real time, thereby achieving higher travel speed and efficiency for electric-drive vehicles, as well as a longer mileage.

[0011] In some possible implementations, the vehicle information acquisition and processing device acquires and processes the information of the vehicle arriving at the entrance of the highway, determines whether the vehicle's maximum continuous driving speed, the vehicle's automatic driving function, the vehicle's power unit type, and the vehicle's power supply device meet the requirements of the highway lane, and also determines whether the vehicle's maximum full load mass meets the requirements of the highway lane, and verifies whether the automatic driving function is in working condition.

[0012] If the vehicle's maximum sustained speed is greater than or equal to the rated maximum speed of the highway lane, and the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control, and the vehicle's power unit type is electric drive, and the vehicle has a power supply device that matches the highway lane power supply device, and the vehicle's maximum full-load mass is less than or equal to the maximum full-load mass of vehicles designed to pass through the highway lane, and the vehicle's automatic driving function is in working condition, then the vehicle information processing result is "pass", the entrance opening and closing device opens, and the vehicle is allowed to enter the highway.

[0013] If the vehicle's maximum continuous speed is less than the rated maximum speed of the highway lane, or the vehicle does not have the automatic driving function to autonomously complete driving from any starting point to any end point on the highway according to program control, or the vehicle's power unit type is not electric drive, or the vehicle does not have a power supply device that matches the power supply device of the highway lane, or the vehicle's maximum full load mass is greater than the maximum full load mass of vehicles designed to pass through the highway lane, or the vehicle's automatic driving function is not in working condition, the vehicle information processing result is "fail", the entrance opening and closing device remains closed, and the vehicle is not allowed to enter the highway.

[0014] In this embodiment, since the technical feature of determining the maximum fully loaded mass of the vehicle is added, it is possible to control the mass (i.e., weight) of vehicles on the road, thereby preventing vehicles with excessive mass from damaging the road. By controlling only vehicles with lower mass (i.e., weight) to be on the road, the designed load-bearing capacity of the road can be much lower than that of current conventional highways, and the construction cost can be reduced.

[0015] In some possible implementations, the maximum fully loaded vehicle mass required by the highway lane is a specific mass selected between 1500kg and 5000kg, for example, 1500kg, or 2000kg, or 3000kg, or 4000kg, or 5000kg, etc.

[0016] In this embodiment, since the maximum fully loaded mass of vehicles that can be on the road is limited to only 3% to 10% of the conventional highway design load of 55,000 kg, a significant reduction in construction costs can be achieved.

[0017] In some possible implementations, the rated maximum speed of the highway lane is a specific speed selected between 150km / h and 450km / h, such as 150km / h, 200km / h, 250km / h, 300km / h, 350km / h, 400km / h, 450km / h, etc. The highway is set with corresponding rated speeds according to the actual conditions such as the curvature of each section, and the vehicle automatic driving function travels according to the rated speed of each section.

[0018] In this embodiment, since the highway lanes are set with a rated speed, and the rated speed is higher than the current conventional 120km / h, all vehicles on the lanes automatically travel at the rated speed, thereby achieving the purpose of improving road speed and traffic efficiency.

[0019] In some possible implementations, the vehicle information acquisition and processing device acquires information about vehicles arriving at the entrance of the highway in order to directly obtain information related to the vehicle's maximum continuous driving speed, automatic driving function, power unit type, power supply device, maximum full load mass, and whether the automatic driving function is in a working state.

[0020] In some possible implementations, the vehicle information acquisition and processing device acquires and processes the information of the vehicle arriving at the entrance of the expressway. To obtain the unique code of the vehicle, the vehicle's maximum continuous driving speed, automatic driving function, power unit type, power supply device, and maximum full-load mass related information corresponding to the unique code that are pre-stored are retrieved, and the vehicle technical characteristics required by the expressway lane are compared and analyzed to determine whether the vehicle technical characteristics meet the requirements of the expressway lane. Alternatively, the vehicle information acquisition and processing device compares and analyzes the vehicle related information corresponding to the unique code of each vehicle with the vehicle technical characteristics required by the expressway lane in advance, and determines whether the vehicle technical characteristics meet the requirements of the expressway lane, and stores the results. After acquiring the unique code of the vehicle, the result of whether it meets the requirements of the expressway lane can be directly obtained. In addition, the vehicle information acquisition and processing device also acquires and processes the information on whether the automatic driving function of the vehicle is in working state.

[0021] In this embodiment, since the relevant information of the vehicle itself is obtained by obtaining the vehicle unique code, the type of information obtained is simplified. In addition, since "whether the vehicle's automatic driving function is in working state" is dynamic information and cannot be associated with the vehicle unique code, it is necessary to obtain the dynamic information separately.

[0022] In some possible implementations, obtaining the unique code of the vehicle is obtaining the license plate number of the vehicle.

[0023] In this embodiment, since the vehicle license plate number is obtained, it can be obtained by using existing camera shooting, which is low-cost and easy to implement. In addition, since "whether the vehicle's automatic driving function is in working state" is dynamic information and cannot be associated with the vehicle's license plate number, the dynamic information is obtained by other means.

[0024] In some possible implementations, the first conductor and the second conductor are both installed on the road surface of a highway driving lane.

[0025] In some possible implementations, the highway carriageway is an elevated structure.

[0026] In this embodiment, due to the use of an elevated structure, the occupied area is greatly reduced, and the land acquisition cost of a newly built elevated expressway is much lower than that of a ground expressway; the elevated structure can also achieve better road surface flatness; under the condition of limiting the maximum full-load mass of vehicles on the road, the strength requirements of the elevated structure are reduced, and the construction cost is correspondingly greatly reduced.

[0027] In the second aspect, the embodiment of the present application provides a highway traffic system, comprising: a highway as described in any of the above-mentioned embodiments, and a vehicle composition whose technical characteristics meet the requirements of the highway. When a vehicle drives to the entrance of the highway, a vehicle information acquisition and processing device acquires and processes the vehicle information, and after judging that the vehicle's technical characteristics meet the requirements of the highway, the vehicle is allowed to enter the highway, the positive and negative electrodes of the vehicle power supply device contact and draw power from the power supply device of the highway lane, the vehicle drives automatically throughout the entire process, the vehicle accelerates to the rated speed of the highway lane, and maintains the rated speed of each section.

[0028] In this embodiment, the expressway and the vehicles constitute an expressway traffic system. The technical characteristics of the vehicles match the requirements of the expressway. Only vehicles that meet the technical characteristics required by the expressway can enter the expressway. The power supply device on the expressway lane supplies power to the vehicle, and the vehicle does not have to worry about running out of battery power during the entire high-speed driving process; the vehicle automatically drives at the rated speed of each section of the expressway lane throughout the expressway, avoiding acceleration, deceleration, lane changing and other situations that are prone to occur in human driving and cannot maintain the rated driving speed, thereby improving the overall driving speed and traffic efficiency of the traffic system.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0035] Figure 1For existing expressways, the overtaking lane 101, the driving lane 102 and the emergency lane located outside the driving lane 102 together constitute the expressway lanes. Since the emergency lane is only for emergency use and is basically not used in daily life, for the sake of simplicity, all the drawings of this specification do not draw the emergency lane, but it does not mean that there is no emergency lane. It should be noted that although the emergency lane is not drawn, all expressways are equipped with emergency lanes on the outermost side. The middle isolation belt 104 separates the lanes in two directions. The lane 105 is the opposite expressway lane, and its vehicle traffic direction is opposite to the vehicle traffic direction of the overtaking lane 101 and the driving lane 102. Motor vehicles such as passenger cars 103, buses 106, and trucks 107 can travel on the expressway. Under normal circumstances, the maximum speed limit of passenger cars 103 is 120km / h, and the maximum speed limit of buses 106 and trucks 107 is 100km / h; in special sections such as mountainous areas, tunnels, and bridges, the maximum speed limit is lower. Expressways also have controlled entrances, and only motor vehicles can enter through the entrances. Non-motor vehicles, pedestrians, etc. are prohibited from taking to the road. Compared with ordinary roads, expressways reduce the types of traffic participants through entrance management, and also eliminate intersections, thereby achieving improved travel speed and efficiency. However, the speed levels of participating vehicles on existing expressways are different. The appropriate speed for passenger cars is above 120km / h, and the appropriate speed for buses and trucks is below 100km / h. Even if passenger lanes and large lanes are divided, due to the prevalence of overtaking and changing lanes, vehicles of different speed levels will inevitably affect each other, resulting in a reduction in the overall travel speed; in addition, different drivers have different driving skills and driving styles. Some can drive according to the expressway speed limit of 120km / h, some may like to drive at a speed of 80km / h~90km / h, some like to change lanes frequently, and some seldom change lanes. Different types of drivers have different driving skills and driving styles. Vehicles driven by drivers will inevitably affect each other, which makes it difficult for the average speed of vehicles on existing highways to reach the upper speed limit of 120km / h (passenger cars) and 100km / h (large vehicles). In the era of "carbon peak and carbon neutrality", electric vehicles are accelerating their popularity, but the unit power consumption of electric vehicles at high speeds is much higher than that of low-speed driving on urban roads. Electric vehicles traveling at high speeds need to be frequently recharged, but there are not many charging piles in highway service areas at present, and the charging speed is slow. Frequent recharging takes a lot of time, which further reduces the average driving speed of the entire journey. With the maturity of the electric vehicle industry chain and the continuous decline in the price of electric vehicles, the number of electric vehicles will accelerate, but the speed and efficiency of existing highways have obvious bottlenecks, which cannot meet the needs of more electric vehicles for faster travel. There is an urgent need for new highways and highway transportation systems that are compatible with electrified, intelligent, and networked electric vehicles.

[0036] The expressway provided in the embodiment of the present application and the vehicles whose technical characteristics meet the requirements of the expressway constitute an expressway traffic system. The expressway traffic system is first introduced below.

[0037] Figure 2 This is a schematic diagram of an application scenario of the highway traffic system for this application. The central business district of the city, such as Zhongguancun 201 in Haidian District, Beijing, gathers many companies and employs a large number of people; Yongqing County 202 in Langfang City, Hebei Province, is located about 100km south of Beijing. At present, the road travel time from Zhongguancun 201 to Yongqing County 202 is about 1.5 hours one way, and it takes more than 3 hours to go back and forth, and it takes longer during the morning and evening rush hours. Due to the long commuting time, there are very few or even no people who work in Zhongguancun 201 and live in Yongqing County 202 every day. The economic development of Yongqing County 202 still has a lot of room for improvement, but due to the long road travel time, the talents, funds, and culture of Zhongguancun 201 are difficult to radiate to Yongqing County 202. After the implementation of the highway traffic system 203 in this application, calculated based on the rated speed of 200km / h, the travel time from Zhongguancun 201 to Yongqing County 202 is only 30 minutes. Combined with the driving time in the urban area, a one-way trip takes only about 40 minutes. Moreover, the 30 minutes on the highway are fully automatic driving, and people can have a full rest in the car. This commuting time is very acceptable, and Beijing's talents and resources can more easily drive the development of surrounding small towns.

[0038] Figure 3This is another application scenario diagram of the highway traffic system for this application. The highway traffic distance from Beijing Financial Street 301 to Shanghai Lujiazui 302 is about 1,200 km. If calculated according to the speed limit of 120 km / h, the driving time is 10 hours, but the actual average speed will be significantly lower than the speed limit. The actual time required is generally 13 to 15 hours. Due to the long time, driving from Beijing Financial Street 301 to Shanghai Lujiazui 302 via the highway is not a comfortable option. There are two main types of higher-speed transportation: airplanes and high-speed trains. The cruising speed of airplanes is about 800 km / h, and the flight speed during takeoff and landing is lower; the speed of high-speed trains is about 350 km / h. Due to the large size of airplanes and high-speed trains, they need to be docked at specially equipped airports and high-speed rail stations. You must go to the station to take an airplane or a high-speed train, and it takes time to go to and from the station. You also need to spend time entering and exiting and waiting in the station. At present, the fastest high-speed rail travel time from Beijing to Shanghai is about 4.5 hours, plus the time of going to and from the high-speed rail station, entering and exiting the station, and waiting time, a total of more than 6 hours; the flight time from Beijing to Shanghai is about 2 hours, plus the time of going to and from the airport, entering and exiting the terminal, and waiting time, a total of more than 4 hours. After the implementation of the expressway traffic system 303 in this application, according to the rated speed of 300km / h, the entire high-speed journey time is 4 hours, plus the driving time in the urban area, the total time from leaving Beijing to entering Shanghai is about 4.5 hours, and you can get on the bus as soon as you leave the door and get off the bus as soon as you arrive at the door, without the need to transfer in the middle, which is more comfortable and convenient, and the time required is close to air travel, which is very practical.

[0039] Figure 4 This is another application scenario diagram of the highway transportation system of this application. The road traffic distance from Beijing Guomao 401 to Shenzhen Qianhai 402 is about 2,200 km. It currently takes more than 22 hours to drive via the highway, which is too long and not suitable as a travel method. The fastest high-speed rail travel time from Beijing to Shenzhen is 8 hours and 10 minutes, plus the time for going to and from the high-speed rail station, entering and exiting the station, and waiting time, a total of about 10 hours; the flight time from Beijing to Shenzhen is about 3 hours, plus the time for going to and from the airport, entering and exiting the terminal, and waiting time, a total of 5 to 6 hours. After the implementation of the highway transportation system 403 in this application, calculated according to the rated speed of 400km / h, the entire high-speed journey time is 5.5 hours, plus the driving time in the urban area, the total time from leaving Beijing to entering Shenzhen is about 6 hours, which is close to the time required for air travel, and is shorter and more convenient than the time required for high-speed rail travel.

[0040] It is understandable that the highway traffic system can also be applied to other short-distance, medium-distance, and long-distance application scenarios, which are not specifically limited in this application.

[0041] Figure 5This is a schematic diagram of an electric drive vehicle involved in this application. The electric drive vehicle 501 is composed of a power battery 502, a drive motor 503, a reducer 504, etc. The answering device 505 can be a Bluetooth device, a WiFi device, or other equipment that can achieve short-range communication; the license plate 506 is installed on the front bumper of the vehicle 501; the power supply device 507 and the power supply device 508 are installed on the bottom plate of the vehicle 501, which can be folded up and put down. After being put down, they can contact the power supply electrode on the ground and draw electricity. The power supply device 507 and the power supply device 508 are connected to the high-voltage electrical system inside the vehicle 501. Since the drive motor can also output high torque at low speed, most electric vehicles only need to be equipped with a single-speed reducer, and do not need to be equipped with a multi-speed gearbox. Most electric vehicles currently on the market have a maximum sustained speed of 180km / h to 200km / h. Electric vehicles with a maximum sustained speed of more than 300km / h have also been mass-produced, such as the Tesla Model s Plaid. Electric vehicles with a maximum sustained speed of more than 400km / h have also been mass-produced, such as the Rimac Nevera. It is completely possible for electric vehicles to achieve a maximum sustained speed of 450km / h, especially when there is a continuous external power supply during driving, without having to consider the capacity, discharge rate, weight, heat dissipation, etc. of the power battery too much, making it easier to achieve. The maximum sustained speed of the current models on sale is around 200km / h, which is the result of comprehensive consideration of many factors, not because the technology cannot achieve higher speeds. The main reason is that the existing highways generally have a speed limit of 120km / h, and the maximum speed of about 200km / h is far higher than the speed limit of the highway, and is sufficient to cope with emergency needs in very few special circumstances. In fact, even higher speeds are rarely used; on the other hand, most models of electric vehicles are single-speed reducers. If the maximum speed of the motor remains unchanged, if the maximum speed of the vehicle is increased, the acceleration performance will be reduced. The acceleration performance may be used every time you start, while the maximum speed is rarely used. Therefore, the OEM tends to improve the acceleration performance and reduce the maximum speed. Thirdly, if the maximum continuous driving speed is increased, the energy consumption will increase exponentially and the cruising range will be significantly shortened when driving at a higher speed. The battery capacity needs to be increased, the cost will increase, and the vehicle weight will increase. Therefore, the maximum speed is the result of taking into account and balancing multiple factors such as road speed limit, vehicle acceleration performance, energy consumption, battery capacity, and vehicle weight. When the speed limit of the highway is increased and real-time power supply can be provided during driving without worrying about energy consumption, it is easy to design and produce electric vehicle products suitable for driving at higher speeds.

[0042] It should be noted that in order to achieve the above-mentioned rated speed of 200km / h, 300km / h, or 400km / h of the highway traffic system, the highway and vehicles need to meet the corresponding technical conditions at the same time. In the case that the highway has met certain technical conditions, the incoming vehicles may not necessarily meet the corresponding technical conditions. For example, if the maximum continuous driving speed of the vehicle is not up to the rated maximum speed of the highway, if such a vehicle enters the highway, it will prevent the following vehicles from driving at the rated speed of the highway, resulting in a decrease in the overall speed.

[0043] To this end, this application provides a highway, Figure 6 A schematic diagram of a highway provided in an embodiment of the present application, such as Figure 6 As shown, the expressway includes an expressway entrance 601, an expressway lane 602, and an expressway exit 603. It should be understood that only a small section of the expressway is drawn in the figure, and the expressway may have multiple expressway entrances 601 and multiple expressway exits 603. The same expressway may include an opposite expressway lane 608, and the driving direction of the expressway lane 608 is exactly 180 degrees different from the driving direction of the expressway lane 602, that is, exactly in the opposite direction. There is a separation belt 607 between the expressway lane 602 and the opposite expressway lane 608, and the separation belt 607 separates the lanes in different directions. In some cases, a expressway may also include only lanes in one direction, and does not include lanes in the opposite direction. The lanes in different directions are exactly the same in principle, so the embodiment of the present application is only described with the expressway lane in one direction. The copper conductive plates 801 and 802 are laid on the highway lane 602 , and the copper conductive plates 801 and 802 are parallel to the highway lane 602 .

[0044] Figure 7 A schematic diagram of a highway entrance provided in an embodiment of the present application, such as Figure 7 As shown, the highway entrance has a limit bar 702 and a rotating device 701 that drives the limit bar to be raised or lowered. The rotating device 701 and the limit bar 702 together form an opening and closing device. Under normal circumstances, the limit bar 702 is in a lowered state (horizontal state), blocking the passage of vehicles, that is, the highway entrance is in a closed state. The rotating device 701 can drive the limit bar 702 to rotate upward, adjusting the limit bar 702 from a horizontal state to a vertical state, and vehicles can enter through the highway entrance, that is, the highway entrance is in an open state.

[0045] The entrance of the expressway is equipped with a vehicle information acquisition device 703, which can be a Bluetooth device or a short-distance communication device such as a WiFi device, and is not limited here. The information acquisition device 703 sends the acquired information to the information processing device 704, which processes the received information and obtains a processing result of "pass" or "fail". The information processing device 704 is connected to the rotating device 701. When the processing result of the information processing device 704 is "pass", the information processing device 704 controls the rotating device 701 to rotate, driving the limit rod 702 to rotate upward, opening the entrance of the expressway, and vehicles can enter through the entrance of the expressway; when the processing result of the information processing device 704 is "fail", the information processing device 704 controls the rotating device 701 not to rotate, and the limit rod 702 remains in a dropped state, keeping the entrance of the expressway closed and blocking vehicles from passing.

[0046] The transponder 505 on the vehicle 501 is used in pair with the information acquisition device 703. If the information acquisition device 703 is a Bluetooth device, the transponder 505 is also a Bluetooth device; if the information acquisition device 703 is a WiFi device, the transponder 505 is also a WiFi device.

[0047] When the vehicle 501 enters the vehicle identification area 705, the information acquisition device 703 establishes a communication connection with the response device 505 on the vehicle 501. The information acquisition device 703 sends a request to the response device 505 of the vehicle 501 to obtain the vehicle's technical feature information. The requested vehicle technical feature information includes: (1) maximum continuous driving speed, (2) automatic driving function, (3) power device type, (4) power device parameters, and (5) whether the automatic driving function is in working state. The response device 505 of the vehicle 501 sends the corresponding vehicle technical feature information to the information acquisition device 703.

[0048] The information acquisition device 703 transmits the collected technical feature information of the vehicle 501 to the information processing device 704. The information processing device 704 processes the technical feature information and obtains a result of "pass" or "fail". The information processing process of the information processing device 704 is described in detail as follows.

[0049] If the rated maximum speed of the highway lane is 200km / h, the rated maximum speed of 200km / h means that under normal circumstances, vehicles should travel at a speed of 200km / h on most sections of the lane. In the case of a few sections with large curvature, the rated speed is slightly lower than 200km / h, and vehicles should also travel at the corresponding rated speed.

[0050] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is as follows: (1) The maximum continuous driving speed of the vehicle is 200 km / h, that is, the vehicle can travel continuously at a speed of 200 km / h for a long time; (2) The vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) The vehicle's power device type is electric drive, that is, the wheels are driven by the motor, and it can be a pure electric vehicle, an extended-range electric vehicle, or even a plug-in hybrid vehicle, etc., which is not limited here, but it must be required that the motor alone can drive the vehicle and can reach the rated maximum speed of 200 km / h on the highway lane; (4) The vehicle has a power supply device that matches the power supply device of the highway lane, that is, the position, size, and adaptive voltage of the vehicle's power supply device are exactly matched with the power supply device of the highway lane, and power can be obtained after contact; (5) The vehicle's automatic driving function is in working state. The five technical features of the vehicle meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "passed".

[0051] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 220 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state. The five technical features of the vehicle meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "passed".

[0052] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 199 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state. Item (1) of the five technical features of the vehicle does not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0053] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 210 km / h; (2) the vehicle does not have the function of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state. Item (2) of the five technical features of the vehicle does not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0054] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 230 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is an internal combustion engine drive; (4) the vehicle does not have a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state. Items (3) and (4) of the five technical features of the vehicle do not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0055] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 240 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle does not have a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state. Item (4) of the five technical features of the vehicle does not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0056] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 250 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is not in working state. The technical status of item (5) of the vehicle does not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed". The information acquisition device 703 acquires information from the vehicle 501 every 20 seconds. If item (5) changes to "the vehicle's automatic driving function is in working state", the five technical features of the vehicle meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "passed".

[0057] The above lists two examples in which the technical features and technical status of the vehicles meet the requirements of the highway lane, and the processing result of the information processor 704 is "passed"; in addition, there are also examples in which the single technical features or technical status of four vehicles and the two technical features of one vehicle do not meet the requirements of the highway lane, and the processing result of the information processor 704 is "failed". It can be understood that if any two, or any three, or any four, or all five technical features and technical status do not meet the requirements of the highway lane, the processing result of the information processor 704 is "failed", which are not listed one by one here.

[0058] In the above embodiment, the rated maximum speed of the highway lane is 200 km / h. It can be understood that the rated maximum speed of the highway lane is 150 km / h, or 300 km / h, or 400 km / h, or 450 km / h, or other values. The information processing process of the information processor 704 is the same. The rated maximum speed of the highway lane is compared with the maximum continuous speed of the vehicle. When the maximum continuous speed of the vehicle is greater than or equal to the rated maximum speed of the highway lane, the technical feature information of the maximum continuous speed of the vehicle meets the requirements of the highway lane.

[0059] When the information processor 704 processes the vehicle's technical features and technical status information and the result is "pass", the information processor 704 controls the rotating device 701 to rotate, and the rotating device 701 drives the limit bar 702 to rotate upward, adjusting the limit bar 702 from a horizontal state to a vertical state, allowing the vehicle to enter the highway. When the information processor 704 processes the vehicle's technical features and the result is "fail", the information processor 704 controls the rotating device 701 not to rotate, keeping the limit bar 702 in a dropped state (horizontal state), blocking the vehicle from entering.

[0060] like Figure 8 As shown, it is a cross-sectional schematic diagram of a highway lane 602. Copper conductive plates 801 and 802 are installed on a roadbed 804. Insulation measures are taken between copper conductive plates 801 and 802 to prevent direct conduction and short circuit. Pavement 803 is laid on the roadbed 804. Pavement 803 is an asphalt pavement or a cement pavement. Pavement 803 is an insulator. Copper conductive plate 801 is connected to wire 805. Copper conductive plate 802 is connected to wire 806. Wire 805 and wire 806 are buried in the roadbed 804 and extend outside the roadbed 804. Wire 805 is connected to the negative pole of the power supply. Wire 806 is connected to the positive pole of the power supply. A potential difference is formed between copper conductive plate 801 and copper conductive plate 802. The potential difference is 400V.

[0061] like Fig. 9 As shown, vehicle 501 is traveling on a highway lane 602. During the driving process of the vehicle, the negative pole 507 of the vehicle power taking device is in contact with and conducted with the pavement copper conductive plate 801, and the positive pole 508 of the vehicle power taking device is in contact with and conducted with the pavement copper conductive plate 802. The pavement copper conductive plates 801 and 802 provide power for the moving vehicle 501.

[0062] In the embodiment of the present application, a vehicle information acquisition device 703 and an information processor 704 are installed at the entrance of the expressway to strictly identify vehicle information. The vehicle is allowed to travel on the expressway only when the above-mentioned five technical features and technical status of the vehicle meet the technical requirements of the expressway for vehicles. If any of the above-mentioned five technical features and technical status of the vehicle does not meet the technical requirements of the expressway for vehicles, the vehicle will not be allowed to travel on the expressway and cannot enter the expressway.

[0063] Before a vehicle that meets the technical requirements enters the expressway, it sets the destination it needs to reach on the vehicle navigation system. The navigation system automatically calculates and plans the route, finds out which exit of the expressway it needs to exit from, and turns on the automatic driving function. After the vehicle enters the expressway, it is driven autonomously throughout the entire journey on the expressway. Since the expressway in the embodiment of the present application is a highly structured road, there are no non-motorized vehicles such as pedestrians, no intersections, no human drivers with different speed preferences, etc., it is very easy to achieve autonomous vehicle driving. For example, autonomous driving on the expressway can be achieved through the currently mature technologies ACC (full-speed adaptive cruise control) and LCC (lane centering). The current automatic assisted navigation driving (NOA, Navigate on Autopilot, the English name is different for each company) technology is also very mature, which can achieve autonomous on and off ramps and enter and exit the expressway. After the vehicle's automatic driving system is turned on, the vehicle accelerates to the rated speed of 200km / h on the ramp section entering the highway and merges into the highway lane. It maintains this speed during normal driving and keeps driving in the center of the lane. It can also keep driving in the center for curves with a certain curvature. When the curvature of the curve is large, the rated speed of the corresponding section is lower than 200km / h. For example, if the rated speed is 150km / h, the automatic driving system controls the vehicle to drive at the rated speed of the section. When it is necessary to exit the highway, the vehicle slows down after entering the ramp leading to the highway exit. During driving, the vehicle's power supply device contacts the metal conductor of the road surface, and the external power supply forms a loop with the vehicle's high-voltage power system through the metal conductor of the road surface and supplies power to the moving vehicle.

[0064] Since the vehicle is driven autonomously throughout the entire process of driving on the highway, the unstable speed control that may occur when driving manually can be avoided, so that the rated speed can be reached or close to it during the entire process of driving on the highway. Similarly, if the rated speed of the highway is 300km / h or 450km / h, and the vehicles entering the highway meet the technical requirements of the highway, then in actual driving, they can reach or close to the rated speed of 300km / h or 450km / h. The highway in the embodiment of the present application is only open to electric vehicles, and does not accept pure fuel-driven vehicles. The reason is that: under the background of carbon peak and carbon neutrality, it has become a historical necessity for electric vehicles to replace fuel vehicles. As a new type of highway, it must of course match the products of the new historical trend; another more realistic reason is that after the driving speed exceeds 120km / h, especially reaching 200km / h, or even 300km / h and 400km / h, the unit mileage fuel consumption of fuel vehicles increases exponentially with the increase in speed, and carbon emissions increase accordingly, which runs counter to the emission reduction target, and the fuel cost will be very high, which greatly reduces the practicality. As the driving speed increases, although the power consumption also increases exponentially, there is a lot of room for the development of clean energy such as solar energy and wind energy, which can make the cost per kilowatt-hour lower and lower, and there is no worry about carbon emissions. Therefore, the use of electric drive has neither environmental burden nor economic burden, and the economic benefits are significant, which is very practical.

[0065] In some embodiments, when the vehicle 501 enters the vehicle identification area 705, the information acquisition device 703 establishes a communication connection with the response device 505 on the vehicle 501. The information acquisition device 703 sends a request to the response device 505 of the vehicle 501 to obtain the vehicle's technical feature information. The vehicle's technical feature information requested to be obtained includes: (1) maximum continuous driving speed, (2) automatic driving function, (3) power device type, (4) power device parameters, (5) whether the automatic driving function is in working state; the vehicle's technical feature information requested to be obtained also includes: (6) the vehicle's maximum fully loaded mass. The vehicle's maximum fully loaded mass is also known as the maximum design gross mass or the maximum allowable gross mass. It refers to the maximum fully loaded mass technically permitted by the automobile manufacturer, including the vehicle's own weight, the total mass of the vehicle when fully loaded, including the passengers (including the driver) and the cargo in the vehicle. The response device 505 of the vehicle 501 sends the corresponding vehicle's technical feature information to the information acquisition device 703. The information acquisition device 703 transmits the collected technical feature information of the vehicle 501 to the information processor 704. The information processor 704 processes the technical feature information and obtains a result of "pass" or "fail". The information processing process of the information processor 704 is described in detail as follows.

[0066] If the rated speed of the highway lane is 300km / h, the maximum fully loaded mass of vehicles allowed to pass is 4000kg.

[0067] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 310 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state; (6) the vehicle's maximum full load mass is 3950 kg. The six technical features of the vehicle meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "passed".

[0068] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 290 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state; (6) the vehicle's maximum full load mass is 4000 kg. Item (1) of the six technical features of the vehicle does not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0069] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 280 km / h; (2) the vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle's power device type is electric drive; (4) the vehicle has a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state; (6) the vehicle's maximum full load mass is 4100 kg. Items (1) and (6) of the six technical features of the vehicle do not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0070] If a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is: (1) the maximum continuous driving speed of the vehicle is 310 km / h; (2) the vehicle does not have the function of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) the vehicle power device type is internal combustion engine drive; (4) the vehicle does not have a power supply device that matches the power supply device of the highway lane; (5) the vehicle's automatic driving function is in working state; (6) the maximum full load mass of the vehicle is 3900 kg. Items (2), (3) and (4) of the six technical features of the vehicle do not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0071] For example, if a vehicle arrives at the vehicle identification area 705, the technical feature information of the vehicle is as follows: (1) The maximum continuous driving speed of the vehicle is 280 km / h; (2) The vehicle's automatic driving function is capable of autonomously completing driving from any starting point to any end point on the highway according to program control; (3) The vehicle's power device type is electric drive; (4) The vehicle does not have a power supply device that matches the power supply device of the highway lane; (5) The vehicle's automatic driving function is not in working state; (6) The maximum full load mass of the vehicle is 4200 kg. Among the six technical features of the vehicle, items (1), (4), (5), and (6) do not meet the requirements of the highway lane, and the information processor 704 processes the technical feature information of the vehicle as "failed".

[0072] The above lists an example in which the technical features and technical status of one vehicle meet the requirements of the highway lane, and the processing result of the information processor 704 is "passed"; in addition, it also lists four examples in which one, two, three, or four technical features or technical statuses of four vehicles do not meet the requirements of the highway lane, and the processing result of the information processor 704 is "failed". It can be understood that if any one, any two, any three, any four, any five, or all six technical features and technical statuses do not meet the requirements of the highway lane, the processing result of the information processor 704 is "failed", which are not listed one by one here.

[0073] When the information processor 704 processes the vehicle's technical feature information as "pass", the information processor 704 controls the rotating device 701 to rotate, and the rotating device 701 drives the limit bar 702 to rotate upward, adjusting the limit bar 702 from a horizontal state to a vertical state, allowing the vehicle to enter the expressway. When the information processor 704 processes the vehicle's technical feature information as "fail", the information processor 704 controls the rotating device 701 not to rotate, keeping the limit bar 702 in a dropped state (horizontal state), preventing the vehicle from entering the expressway.

[0074] According to some other embodiments of the present application, the rated maximum speed of a highway lane can be set to other values ​​according to actual needs, such as 150km / h, 180km / h, 200km / h, 250km / h, 350km / h, 400km / h, 450km / h, etc.; in some sections with large curvature, the rated speed can be reduced accordingly; the maximum full-load mass of vehicles allowed to pass through a highway lane can be designed to other values ​​according to actual needs, such as 2500kg, 3000kg, 3500kg, 4500kg, 5000kg, etc., and can even be designed to 1500kg, 2000kg, specifically for use by ultra-light vehicles.

[0075] Since the vehicle technical characteristic information requested also includes the vehicle's maximum fully loaded mass, that is, the maximum fully loaded mass of the vehicle that can be on the road is limited, the limit value in the embodiment of the present application is only 3% to 10% of the conventional highway design load of 55,000 kg. As the design load is reduced, the strength requirements of the corresponding structures are also reduced accordingly, thereby achieving a significant reduction in construction costs.

[0076] As a possible implementation, the information acquisition device Bluetooth device 703 automatically completes pairing and establishes a communication connection with the transponder Bluetooth device 505 of the vehicle 501, and the information acquisition device Bluetooth device 703 sends a request to the transponder Bluetooth device 505 of the vehicle 501 to obtain the vehicle's unique identification code. The vehicle's unique identification code is also known as the VIN code, usually referred to as the "vehicle frame number", which is a set of character codes assigned to the vehicle by the vehicle manufacturer. The vehicle's unique identification code is unique worldwide. The transponder Bluetooth device 505 of the vehicle 501 sends the vehicle's unique identification code to the information acquisition device Bluetooth device 703, and the information acquisition device Bluetooth device 703 sends the obtained vehicle's unique identification code to the information processor 704. The information processor 704 retrieves the corresponding vehicle technical feature information from the database through the vehicle's unique identification code. The retrieved vehicle technical feature information includes the vehicle's maximum continuous driving speed, the vehicle's automatic driving function, the vehicle's power device type, the vehicle's power device parameters, and may also include the vehicle's maximum full load mass. In addition, it is necessary to verify whether the automatic driving function is in working state, which is a dynamic information; while the information that can be retrieved from the vehicle unique identification code can only be the technical feature information of the vehicle itself, which can be defined as "static technical feature information". Therefore, the information acquisition device Bluetooth device 703 needs to send another request to the transponder Bluetooth device 505 of the vehicle 501 to request to obtain the information whether the vehicle's current automatic driving function is in working state, and the transponder Bluetooth device 505 of the vehicle 501 sends the information acquisition device Bluetooth device 703 that the vehicle's current automatic driving function is in working state or not in working state. The information processor 704 processes the technical feature information and technical status information retrieved above, and the specific processing process is as described above, and finally obtains the result of "pass" or "fail". When the information processor 704 processes the technical feature information and technical status information of the vehicle as "pass", the information processor 704 controls the rotating device 701 to rotate, and the rotating device 701 drives the limit rod 702 to rotate upward, adjusting the limit rod 702 from a horizontal state to a vertical state, and allowing the vehicle to enter the highway. When the information processor 704 processes the technical feature information and technical status information of the vehicle and the result is "fail", the information processor 704 controls the rotating device 701 not to rotate, keeps the restriction bar 702 in the dropped state (horizontal state), and blocks the vehicle from entering the highway.

[0077] As a possible implementation, an optimized method can be used in the link of information processing by the information processor 704, that is, pre-processing the information in advance. When the information processor 704 processes the information of a specific vehicle 501, it only needs to retrieve the "static technical feature information" result corresponding to the unique code of the vehicle 501 from the database, and the result is one of "pass" or "fail". Specifically, when the technical requirements of a highway lane are determined, for example, the rated maximum speed of the highway lane is 400km / h, the vehicle's automatic driving function is required to be able to autonomously complete driving from any starting point to any end point on the highway according to program control, the vehicle power device type is required to be electric drive, the vehicle is required to have a power supply device that matches the highway lane power supply device, and the maximum full load mass allowed for passing vehicles is 3500kg. The information processor 704 of the highway lane pre-processes the information in advance, collects information of various types of vehicles on the market, and analyzes and determines which types of vehicle technical feature information meets the requirements of the highway lane technical parameters, and saves the unique identification codes of these types of vehicles in the database, and saves the corresponding results as "passed" to form a white list; the core fields (such as the first 10 digits of the identification code) in the unique identification codes of these types of vehicles can also be saved in the database, and the corresponding results are saved as "passed" to form a white list. The information acquisition device WiFi device 703 sends the acquired vehicle unique identification code to the information processor 704, and the information processor 704 compares the vehicle unique identification code with the vehicle unique identification code in the database white list. If the vehicle unique identification code is in the white list, the static technical feature information "passed" result is obtained; if the vehicle unique identification code is not in the database white list, the static technical feature information "failed" result is obtained. If the core field in the vehicle unique identification code is saved in the database whitelist, the information processor 704 first extracts the core field in the unique identification code of the specific vehicle 501, and then compares the core field in the vehicle unique identification code with the core field in the vehicle unique identification code in the database whitelist. If the core field is in the whitelist, the static technical feature information is obtained as a "pass" result; if the core field is not in the whitelist, the static technical feature information is obtained as a "fail" result.The processing result of the static technical feature information also needs to be comprehensively judged together with the processing result of the dynamic information "whether the automatic driving function is in working state". For example, if the processing result of the static technical feature information is "passed" and the processing result of the dynamic information "the automatic driving function is in working state" is "passed", then the final processing result is "passed", and the vehicle is allowed to enter the expressway; if the processing result of the static technical feature information is "failed", regardless of whether the automatic driving function is in working state or not, the final processing result is "failed", and the vehicle is not allowed to enter the expressway; if the processing result of the dynamic information "the automatic driving function is not in working state" is "failed", regardless of whether the processing result of the static technical feature information is "passed" or "failed", the final processing result is "failed", and the vehicle is not allowed to enter the expressway.

[0078] As a possible implementation method, an optimized method can also be used in the vehicle information acquisition and information processing links. The information of the vehicle 501 collected by the information acquisition device 703 is the license plate number and the vehicle type. The vehicle 501 can be photographed by taking a photo, and the license plate number and the vehicle type (such as a passenger car, a bus, a truck, a motorcycle, etc.) can be identified by the image recognition system. At present, the image recognition technology is very mature and has been widely used. The information processor 704 pre-processes the license plate number and the vehicle type information in advance. When the information processor 704 processes the information of a specific vehicle 501, it only needs to retrieve the "static technical feature information" corresponding to the license plate number and the vehicle type of the vehicle 501 from the database, and the result is one of "pass" or "fail". Specifically, when the technical requirements of a highway lane are determined, for example, the rated maximum speed of the highway lane is 450km / h, the vehicle's automatic driving function is required to be able to autonomously complete driving from any starting point to any end point on the highway according to program control, the vehicle's power device type is required to be electric drive, the vehicle is required to have a power supply device that matches the highway lane power supply device, and the maximum full load mass of the allowed vehicle is 2500kg. The information processor 704 of the highway lane pre-processes the information in advance, that is, it connects with the vehicle information database of the government vehicle management department, screens out vehicles whose vehicle technical feature information meets the technical parameter requirements of the highway lane, and saves the license plate number and vehicle type of these vehicles in the database, and saves the corresponding "static technical feature information" result as "passed" to form a white list. The information acquisition device camera 703 sends the acquired vehicle photo to the information processor 704. The information processor 704 first identifies the license plate number and vehicle type of the license plate 506 of the vehicle 501, and then compares the license plate number and vehicle type with the license plate number and vehicle type in the database white list. If the license plate number and the corresponding vehicle type are in the white list, the static technical feature information is "passed"; if the license plate number and the corresponding vehicle type are not in the database white list, the static technical feature information is "failed". In addition, it is also necessary to obtain dynamic information "whether the automatic driving function is in working state". As a possible implementation method, the vehicle is in an Internet-connected state, and the vehicle dynamic information "whether the automatic driving function is in working state" can be queried through the Internet. According to the license plate number and vehicle type information that have been obtained, the dynamic information "whether the automatic driving function is in working state" of the corresponding vehicle can be queried through the Internet; as another possible implementation method, the vehicle has an external display screen that can display a QR code (corresponding to a website that can be accessed on the Internet). After the information acquisition device camera 703 takes a photo, it recognizes the QR code and reads the dynamic information "whether the automatic driving function is in working state" of the Internet-connected vehicle online through the parsed website.Of course, the dynamic information of the vehicle "whether the automatic driving function is in working state" can also be obtained through the aforementioned communication devices such as Bluetooth devices and WiFi devices, which are not listed here one by one. The processing result of the static technical feature information is comprehensively judged with the processing result of the dynamic information "whether the automatic driving function is in working state". For example, if the processing result of the static technical feature information is "passed" and the processing result of the dynamic information "the automatic driving function is in working state" is "passed", the final processing result is "passed" and the vehicle is allowed to enter the expressway; if the processing result of the static technical feature information is "failed", regardless of whether the automatic driving function is in working state or not, the final processing result is "failed" and the vehicle is not allowed to enter the expressway; if the processing result of the dynamic information "the automatic driving function is not in working state" is "failed", regardless of whether the processing result of the static technical feature information is "passed" or "failed", the final processing result is "failed" and the vehicle is not allowed to enter the expressway.

[0079] As a possible implementation, Fig.10 A schematic diagram of a highway provided in an embodiment of the present application, such as Fig.10As shown, the expressway includes an expressway entrance 1001, an expressway lane 1002, and an expressway exit 1003. It should be understood that only a small section of the expressway is drawn in the figure, and the expressway may have multiple expressway entrances 1001 and multiple expressway exits 1003. The same expressway may include an opposite expressway lane 1008, and the driving direction of the expressway lane 1008 is exactly 180 degrees different from the driving direction of the expressway lane 1002, that is, it is exactly in the opposite direction. There is a separation belt 1007 between the expressway lane 1002 and the opposite expressway lane 1008, and the separation belt 1007 separates the lanes in different directions. In some cases, a expressway may also include only a lane in one direction, and does not include a lane in the opposite direction. The lanes in different directions are exactly the same in principle, so the embodiment of the present application is only described with the expressway lane in one direction. Aluminum alloy conductive plates 801 and 802 are laid on the highway lane 1002, and the aluminum alloy conductive plates 801 and 802 are parallel to the highway lane 1002. The rated maximum speed of the highway lane in the embodiment of the present application is 300km / h, the vehicle automatic driving function is required to be able to autonomously complete driving from any starting point to any end point on the highway according to program control, the vehicle power device type is required to be electric drive, the vehicle is required to have a power supply device that matches the highway lane power supply device, the maximum full load mass allowed for the vehicle is 3500kg, and the vehicle automatic driving function is required to be in working state. Vehicle 1004 arrives at the entrance 1001 of the highway, and the vehicle information acquisition device 703 acquires the relevant information of vehicle 1004, and determines whether to allow vehicle 1004 to enter the highway after processing. The working process of the vehicle information acquisition and processing device and the opening and closing device at the entrance 1101 of the highway is the same as that described in the previous embodiment, and will not be repeated in this embodiment. Piers 1011, 1012 and 1013 are built on pile foundations, and the tops of the piers are on the same horizontal plane. Highway lanes 1002 are built on piers 1011, 1012 and 1013. Since the highway is built on the piers, it becomes an elevated road. Highways built on elevated roads are mature technologies, and the technical details of elevated roads will not be described here.The advantages of the elevated road of this embodiment are, on the one hand, that it can be very flat, which is conducive to increasing the rated maximum speed of the expressway; on the other hand, combined with the feature that the maximum full-load mass of the vehicles allowed to pass is 3,500 kg, which is only less than 10% of the current design load of 55,000 kg for conventional expressways, the structural strength requirements of the elevated road are greatly reduced, which can greatly reduce the construction cost; thirdly, for existing expressways built on the ground, the land acquisition and demolition costs account for a considerable proportion of the overall cost. After being converted into elevated roads, the land area occupied by the piers is greatly reduced, so the land acquisition and demolition costs are greatly reduced. With more than 100,000 kilometers of expressways in the country, since the construction cost of the new expressways of this embodiment is very low, the construction of a large number of new expressways of this embodiment will not only not become a burden on the social economy or cause waste, but on the contrary, it will become a booster for social and economic development.

[0080] As a possible implementation, Fig.11 A schematic diagram of a highway provided in an embodiment of the present application, such as Fig.11As shown, the expressway includes an expressway entrance 1101, an expressway lane 1102, and an expressway exit 1103. It should be understood that only a small section of the expressway is drawn in the figure, and the expressway can have multiple expressway entrances 1101 and multiple expressway exits 1103. It also includes an expressway lane 1105 in the same direction as the expressway lane 1102. It also includes an expressway lane in the opposite direction, which is the same in principle. Therefore, the embodiment of the present application is only described with only one direction of the expressway lane. The rated speed of the expressway lane 1102 is 200km / h, and the rated speed of the expressway lane 1105 is 300km / h. Copper conductive plates 1106 and 1107 are laid on the expressway lane 1002 in parallel with the extension direction of the road. The copper conductive plate 1106 is connected to the negative pole of the power supply, and the copper conductive plate 1107 is connected to the positive pole of the power supply. The voltage of the power supply is 800V. Copper conductive plates 1108 and 1109 are laid on the highway lane 1005 in parallel with the extension direction of the road. Copper conductive plates 1108 are connected to the negative pole of the power supply, and copper conductive plates 1109 are connected to the positive pole of the power supply. The voltage of the power supply is 800V. Vehicle 1104 arrives at the entrance 1101 of the highway, and the vehicle information acquisition device 703 acquires the relevant information of vehicle 1104. Since the highway has two lanes in the same direction, the rated speeds are 200km / h and 300km / h respectively. Therefore, if the maximum continuous driving speed of vehicle 1104 is greater than or equal to 200km / h and meets other technical requirements, it will be allowed to enter the highway. The working process of the vehicle information acquisition and processing device and the opening and closing device at the entrance 1101 of the highway is the same as that described in the previous embodiment, and will not be repeated in this embodiment.If the maximum continuous speed of vehicle 1104 is greater than or equal to 200km / h but less than 300km / h, vehicle 1104 can only travel on highway lane 1102 and cannot enter highway lane 1105. If the maximum continuous speed of vehicle 1104 is greater than or equal to 300km / h, vehicle 1104 can choose to travel on highway lane 1102 at a rated speed of 200km / h, or choose to travel on highway lane 1105 at a rated speed of 300km / h. Usually, in order to improve the speed and efficiency, the vehicle 1104 will choose to travel on highway lane 1105 at a rated speed of 300km / h. Since highway lane 1105 is on the inside, the process of vehicle 1104 entering highway lane 1105 is as follows: vehicle 1104 passes through the highway lane 1102. After reaching the highway entrance 1101, in the automatic driving mode, the vehicle first enters the highway lane 1102 and maintains a speed of 200 km / h. The power taking device of the vehicle 1104 contacts the copper conductive plates 1106 and 1107 on the highway lane 1102 and obtains power. When there is a large space between the vehicles in front and behind the highway lane 1105, the power taking device of the vehicle 1104 disconnects from the copper conductive plates 1106 and 1107 on the highway lane 1102 and uses its own power battery for power. The vehicle 1104 merges into the highway lane 1105 and accelerates to 300 km / h. Maintaining a speed of 300 km / h, the power taking device of the vehicle 1104 contacts the copper conductive plates 1108 and 1109 on the highway lane 1105. Piers 1111, 1112 and 1113 are built on pile foundations, and the tops of the piers are on the same horizontal plane. Highway lanes 1102, 1105 and highway lanes in the opposite direction are built on piers 1111, 1112 and 1113. Since the highway is built on the piers, it is an elevated road. Highways built on elevated roads are mature technologies in themselves, and the technical details of elevated roads will not be described here. The advantages of elevated roads are that, on the one hand, they can be very flat, which is conducive to increasing the rated maximum speed of highways; on the other hand, they can greatly reduce construction costs. For existing highways built on the ground, the land acquisition and demolition costs account for a considerable proportion of the overall cost. After being converted into elevated roads, the land area occupied by the piers is greatly reduced, so the land occupation and demolition costs are greatly reduced. In addition, this embodiment limits the maximum full-load mass of vehicles using the expressway to within 5,000 kg, which is only about 10% of the current design load of 55,000 kg for conventional expressways. The construction cost of the elevated expressway in this embodiment is further reduced.With more than 100,000 kilometers of expressways already existing in the country, since the construction cost of the new expressways of this embodiment is very low, building a large number of new expressways of this embodiment will not only not become a burden on the social economy or cause waste, but on the contrary, will become a booster for social and economic development.
