Background Art

[0061] The present application will be further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0062] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0063] Terms such as "upper," "lower," "left," "right," and "center" used in this application are generally intended to facilitate intuitive understanding when compared with the accompanying drawings and are not intended to be absolute limitations on positional relationships in actual products. Changes to these relative positional relationships are considered within the scope of this application without departing from the technical concepts disclosed herein.

[0064] Example

[0065] In order to integrate existing smart connected vehicles and electric vehicles, to further expand the concept of networking in smart connected vehicles and integrate the power contact network, to concretize and harden smart connected vehicles, and at the same time to improve cost performance and make smart connected vehicles more popular, this application proposes a contact network device that can be installed on a smart car, and a smart connected system used in conjunction with the contact network device.

[0066] The inventors consulted relevant materials and found that in the article "Technical and Economic Analysis of Electrified Highways and Electric Vehicles" written by Zhang Yaoping and Liu Benlin, 1.3 Electric Vehicle Power Collection Scheme, (2) Side Power Collection, it is recorded: "The disadvantage of side power collection is that it requires high accuracy for electric vehicles to travel along the road, that is, the vehicle must maintain an appropriate distance from the power supply device on the road during the power collection process and cannot deviate excessively; the side power collection pole must have a high positioning accuracy, such as the upper and lower deviations of the power collection brush cannot be too large, otherwise it will not be able to contact the grid normally for power collection." Therefore, there are still many problems with the current side power collection technology, and the existence of these problems limits the production and application of the side power collection technology.

[0067] The touch-network device provided in this application, and the intelligent network connection system used in conjunction with the touch-network device overcome the shortcomings of side power collection. Applying them to smart cars solves the charging and endurance problems of electric vehicles, and also redefines smart network connection cars. This new network connection system is a major breakthrough and improvement based on the original smart network connection car.

[0068] This application installs the contact network device provided by this application on the basis of the original smart car, and obtains a new smart connected car. Furthermore, on this basis, an intelligent connected system is set up for use with the contact network device, and a new transportation system is constructed as a whole. Specifically, the transportation system is mainly divided into a smart car part and a connected part; the connected part can be divided into an information system (Internet) and a power supply system (contact network). The connected part can be erected in the middle of the road or about 80 cm away from both sides of the road. When the smart car is driving on a road with connected facilities, the connected part provides electricity and basic sensor information to enable the car to move forward, and the connected part can charge the car's battery at the same time; when the smart car is driving on a road without connected facilities, it is powered by the battery or internal combustion engine in the car, and can be driven by a person or provided with information by a simple remote control driving system to enable the car to move forward.

[0069] Therefore, the smart car in this application can be driven on roads with connected facilities as well as on roads without connected facilities.

[0070] The system architecture and implementation principles of this new transportation system are described in detail below with reference to the accompanying drawings.

[0071] 1. Smart car part

[0072] The smart car in this application is based on the existing smart car, with an added network device, see Figure 1 The main principle is: the smart car 1 is connected to the contact network 3 (a power supply device belonging to the intelligent network system) built on the road through the contact network device 2 installed in the front (of course it can also be on the side or rear). The contact network 3 provides electricity to enable the vehicle to move forward safely at high speed, and at the same time charge the battery.

[0073] The contact network device 2 can be installed on the underframe of the automobile chassis, and can be divided into two parts: a fixing seat 21 and a telescopic rod 22.

[0074] Above-mentioned holder 21 can directly adopt the telescopic device of automatic telescopic door, only adds a clutch in addition at the output shaft end of reduction motor, on clutch shaft (or on belt gear shaft), also be equipped with steering angle sensor and torque sensor, for automobile electronic control unit (ECU) provides steering information. Certainly, on holder 21, also can install mechanical steering device (left-hand turn pin 211 and right-hand turn pin 212), when clutch is in closing state, left-hand turn pin 211, right-hand turn pin 212 on holder 21 are retracted in original position, when clutch is in leaving state, left-hand turn pin 211 and right-hand turn pin 212 are pushed forward, when the relative displacement of automobile and contact network deviates from and surpasses certain distance like this (about 20 centimetres), the protruding pin on telescopic rod 22 touches right-hand turn pin 212 (or left-hand turn pin 211), makes automobile to left (or right) slew by the direction control lever action of steering brake line pulling automobile; Change left and right turning pin into sliding rheostat, also can provide different resistance values for rotation, control left and right rotation.

[0075] The telescopic rod 22 is mainly composed of: an electric push rod 223, a larger than mark bayonet 224, an electromagnetic latch lock 222, a flat steel with appropriate elasticity 226, an electric contact shoe 227, a rotating device 221 and a sensor. The structural characteristics of each component are described in turn below:

[0076] Electric push rod 223: Choose one with a slightly larger stroke, such as about 400mm.

[0077] Greater than bayonet 224: When the car is running, it is impossible to be absolutely stable, and it is inevitable that there will be a certain amount of up and down shaking, which needs to be adapted. A graphite slider is clamped at the bottom of the bayonet.

[0078] Electromagnetic latch bolt lock 222: When the neutral wire of the contact network (which also functions as a track) is stuck in the larger-than-size slot, the electromagnetic latch bolt lock is required to hold the neutral wire firmly in place to prevent it from falling out. When the car is about to leave the contact network, the electromagnetic latch bolt lock is energized and opened, and at the same time the clutch is engaged, the motor is started, and the telescopic rod is retracted.

[0079] Flat steel 226 with appropriate elasticity: mainly to adapt to the bumps that may occur when the car is running, and its elasticity mainly has a certain value in the up and down directions.

[0080] Electric contact shoe 227: The graphite slider is clamped between steel plates to form an electric contact shoe, which is the same as the electric contact shoe of trolleybus.

[0081] Rotating device 221: If the electric shock boot 227 is extended directly, it will touch the live wire shield 311, so first use the rotating device 221 to rotate the electric push rod 223 90 degrees, then turn on the electric push rod 223, push it to the top and then rotate it 90 degrees back, then retract the electric push rod through the limit switch about 12 cm, so that the graphite electric shock boot is stuck on the live wire (or a 90-degree pull-folding device can also be used).

[0082] Sensors: Mainly ultrasonic radar sensors (belonging to the ultrasonic radar ranging system used for distance measurement) and cameras installed in the area larger than the bayonet 224. The ultrasonic radar ranging system mainly detects the distance between the car and the contact network, and controls whether the telescopic rod is extended according to the set data; the camera is set for the driver to observe the contact network neutral line through the screen in the car.

[0083] For details, see Figure 2-6 One end of the fixing seat 21 of the contact network device 2 provided in the present application (for ease of understanding, you can refer to the automatic door, which is the place where the glass door is clamped on the sliding rail of the automatic door) is provided with a connecting piece 213 for connecting the telescopic rod 22; the telescopic rod 22 includes an outer cover tube 225 installed on the elastic flat steel, a rotating device 221 is provided in the outer cover tube 225, and an electric push rod 223 connected to the rotating device 221, and the free end of the electric push rod 223 is provided with a receiving Antenna 229, insulator 228 and electric shock shoe 227, one end of the outer cover tube 225 is provided with a larger than bayonet 224, and an electromagnetic inclined tongue lock 222 is provided on the larger than bayonet 224; the electric push rod 223 is driven to extend or retract from the end of the outer cover tube 225 provided with the larger than bayonet 224; the larger than bayonet 224 is used to connect the contact network neutral wire 310, and the electromagnetic inclined tongue lock 222 is used to clamp the contact network neutral wire; the electric shock shoe 227 is used to connect the contact network live wire.

[0084] The outer cover tube 225 of the telescopic rod 22 is a square cylindrical tube. The outer cover tube 225 is installed at one end of the flat steel 226. The other end of the flat steel 226 is connected to the connecting piece 213. The end of the outer cover tube 225 with a bayonet is facing the contact network.

[0085] The greater than sign bayonet 224 is V-shaped, with the fork on the bayonet facing away from the electric push rod 223; a graphite slider is clamped at the bottom of the bayonet; and the electric shock shoe is composed of steel plates and a graphite slider clamped between the steel plates.

[0086] The aforementioned rotating device is used to rotate the electric push rod. Driven by the rotating device and the electric push rod, the electric contact shoe approaches the external contact network and is connected to the live wire of the external contact network. A cable drag chain 2210 is also provided within the outer housing 225. In one embodiment, this cable drag chain 2210 can be replaced with a spiral wire. As the electric push rod retracts and retracts, the cable drag chain 2210 prevents the wires drawn from the electric contact shoe from becoming tangled. Similarly, a cable drag chain is also provided within the fixing base 21. In one embodiment, this cable drag chain can be replaced with a spiral wire. As the telescopic rod 22 retracts and retracts, the cable drag chain prevents the wires drawn from the connector 213 from becoming tangled.

[0087] When the smart car provided by this application is traveling on a highway with a contact network, the telescopic rod of the contact network device on the vehicle is clamped on both sides of the contact network's live and neutral wires (the clamping force can be set to approximately 10 kilograms). The car automatically drives along the contact network, charging while driving. The neutral and live wires of the power supply contact network also serve as tracks. Even if the car accidentally experiences up and down bumps or swaying forward, the contact shoe and the conductive wire can still maintain close contact. Only the relative displacement (left and right) of the contact network device fixing base and the telescopic rod changes. This also facilitates the use of this change to set sensors and automatically control steering. Furthermore, the general car steering control has an automatic self-centering function, so an automatic self-centering interval of approximately 40 centimeters should be set between the relative displacement of the fixing base and the telescopic rod.

[0088] In this way, the smart car can easily go offline, touch the line and overtake. When driving on other roads without power supply systems, the contact network device can be retracted into the car and only extended to connect to the contact network in places with network facilities.

[0089] Since the smart car provided in this application uses the contact network as a power source, its power will be very strong, and naturally the running speed will be greatly improved accordingly.

[0090] Furthermore, the smart car provided by this application can be equipped with a neutral-contact track brake device to disperse the car's inertial energy onto the more robust neutral track. The brake disc of this device can be positioned adjacent to the neutral track and only extends toward and securely grips the track when emergency braking is required. Due to the presence of the track, the car will not fling out or roll over even after a collision.

[0091] 2. Internet Information System

[0092] The networked part of the new transportation system proposed in this application includes a networked information system (Internet) and a networked power supply system (contact network).

[0093] The network information system mainly consists of: optical cables, wifi routers, leaky cables, ultrasonic radars, cloud software, communication systems, etc. The system is also installed along the power supply contact network in the middle or on both sides of the road. Figure 7 .

[0094] The structural characteristics of each component are described below:

[0095] 1. Optical cable: Optical cables are laid along the contact network and can be connected to the Internet.

[0096] 2. Wi-Fi: Separate the optical fiber from the optical cable and then install the Wi-Fi router 33 in sections. Its power supply is connected to the power line in front of the relay.

[0097] 3. Leaky cable: Use a leaky cable to connect the WiFi antenna interface and distribute it along the contact network; the receiving antenna 229 on the smart car contact network device can receive the Internet signal at a close distance.

[0098] 4. Ultrasonic Sensors (i.e., ultrasonic radars 36): The ultrasonic radars can be numbered and arranged in two parallel groups on the support posts 35 of the overhead catenary 3. The first group detects all objects in the nearest lane, while the second group detects all objects in the secondary lane. The signals are transmitted via Wi-Fi to cloud-based software. After processing, the signals are also transmitted via Wi-Fi to the onboard computer or mobile phone. The first group of radars can generally detect the presence of other large and medium-sized objects within the lane within 500-1000 meters ahead, allowing the cloud-based software to control acceleration and deceleration.

[0099] The steering of the car can also be controlled by ultrasonic radar so that the car travels along the contact network. The radar can be installed on the side of the car near the contact network or on one end of the fixed base 21 near the contact network. If the left and right distances between the car and the side of the contact network are greater than 1 meter, the radar setting value (i.e., the farthest distance setting value) is exceeded, and the relay is closed, and the motor of the power steering system is connected to control the wheels to turn inward (i.e., turn in the direction close to the contact network); if the distance is less than 1 meter, the relay is disconnected, and the car automatically returns to the center; if the distance is less than 0.5 meter, the radar setting value (i.e., the closest distance setting value) is exceeded, and another relay is closed, and the motor of the power steering system is connected to control the wheels to turn outward (i.e., turn away from the contact network); if the distance is greater than 0.5 meter, the relay is disconnected, and the car automatically returns to the center. That is, it is ensured that the car travels along the contact network within a range of 0.5 to 1 meter from the contact network. The above-mentioned farthest distance setting value and the closest distance setting value can be set manually.

[0100] 5. Cloud software: You can directly use existing software or develop new software.

[0101] 6. Communication system: It is difficult to install Wi-Fi and radar in places where there are no contact network facilities (such as intersections). Therefore, it is necessary to build other wireless communication systems, such as 5G, to provide protection for remote control driving.

[0102] The networked information system in this application is used to realize the information interconnection of the networked power supply system, the contact network device and the smart car. Generally speaking, the networked information system includes an optical cable set along the contact network, optical fibers branched from the optical cable, and Wi-Fi routers set in sections on the optical fibers. The Wi-Fi antenna interface is connected to a leaky cable distributed along the contact network; the networked information system also includes an ultrasonic radar ranging system installed on a pillar. The ultrasonic radar ranging system is used to detect the position of all objects in the lane and transmit the detected signal to the cloud via Wi-Fi (in a specific application example, it can be the cloud of the main station control center). The signal output by the cloud processing is then transmitted via Wi-Fi to the electronic control unit and screen of the smart car, as well as the car controller or mobile phone.

[0103] In one embodiment, two sets of ultrasonic radar ranging systems are installed along the contact network, one set of ultrasonic radar ranging systems is used to detect the positions of all objects in the first lane, and the other set of ultrasonic radar ranging systems is used to detect the positions of all objects in the second lane; the cloud or the main control center processes the signals received from the ultrasonic radar ranging systems into control signals for controlling the steering, acceleration, deceleration and braking of the smart car.

[0104] Of course, in order to adapt to places where there is no contact network, the networked information system also includes a wireless communication system installed in the location where there is no contact network. The wireless communication system is interconnected with the main station control center and the electronic control unit of the smart car to take over the networked information transmission at the contact network location.

[0105] 3. Networked Power Supply System

[0106] The interconnected power supply system primarily refers to the overhead power line system connected to the substation, referred to as the catenary in this article. The catenary is not an overhead line, but rather a "side line" installed at a relatively low position (about 80 centimeters above the ground) along the side or center of the highway.

[0107] See also Figure 7 The overhead contact network 3 is constructed along the road in the middle or on both sides of the road and mainly consists of the overhead contact network live steel bare wire 37, live aluminum cable 38, insulator 39, overhead contact network neutral wire 310, live wire protective cover 311, top protective cover 31, and support 35. The structural characteristics of each component are described below:

[0108] 1. Live steel bare conductor of contact network: It refers to the conductor in contact with the electric shock shoe, and can be round.

[0109] 2. Live wire aluminum cable: Due to the high resistivity of steel conductors, aluminum conductors are needed to assist in carrying large currents.

[0110] 3. Insulator: Insulators are only installed at the live wire, and you can buy the appropriate model on the market.

[0111] 4. Contact network neutral wire: It should be made of square steel to allow the oblique tongue lock to work; since it also serves as a track, it should be made stronger.

[0112] 5. Live wire protection cover: It is mainly used to protect the live wire and prevent short circuit.

[0113] 6. Top protective cover: It is mainly used to protect the entire contact network system and prevent the influence of rain, snow and other foreign objects.

[0114] 7. Pillar: It is used to support the contact network and protective cover. In particular, the contact network pillars should be stronger and have a higher distribution density.

[0115] The power supply system of the networked power supply system in this application can be optionally 220V AC, which is convenient for connecting and using WiFi and radar equipment; the live wire in the conductive wire is protected by an insulating protective cover, and then protected again by a top protective cover. At the same time, when constructing the contact network, relays are installed at certain intervals to connect and shut down the contact network power supply according to the operating conditions of the car (which can be obtained through WiFi), to prevent no-load power consumption, and to prevent accidental electric shock to ensure safety.

[0116] 4. Autonomous Driving and Unmanned Driving

[0117] The networked part of the new transportation system proposed in this application cooperates with smart cars to realize automatic driving and unmanned driving. Specifically, automatic driving and unmanned driving can be divided into unmanned driving along the contact network and simple remote control driving.

[0118] (1) Unmanned driving along the contact line

[0119] Unmanned driving along the catenary means that the telescopic rod is locked in the left and right directions by the live and neutral wires of the catenary. The relative displacement of the fixed base and the telescopic rod controls the steering of the vehicle. There are two types of steering control: electronic and mechanical.

[0120] The electronic type means that a steering angle sensor and a torque sensor are installed on the clutch shaft of the fixed seat (or on the belt gear shaft) to provide information to the vehicle's electronic control unit (ECU).

[0121] The mechanical type means that the best position is when the extended shaft connecting the car telescopic rod and the fixed seat is in the middle position of the fixed seat. When the deviation to the left (or right) exceeds 20 cm, the protruding pin on the telescopic rod touches the left and right turning pins on the fixed seat, and the car steering joystick is pulled through the brake wire to make the car turn right (or left).

[0122] In addition, cloud-based software can control steering angles based on Wi-Fi installed on the contact line and the vehicle's current location. Radar can also detect the presence of other large and medium-sized objects within the lane within 500-1000 meters ahead of the vehicle, allowing acceleration and deceleration to be controlled through cloud-based software. Generally, braking commands are only issued in emergencies due to the long prediction distance.

[0123] Furthermore, we can also use ultrasonic radar to control the steering of smart cars so that they can drive along the contact line.

[0124] In summary, of the four steering methods mentioned above, the electronic method is not easy to set the return range and is prone to serpentine swing, so it still needs improvement; the mechanical method is relatively reliable and compatible with other methods, and should be used as the standard steering structure; the cloud-controlled method requires a large amount of data and is easily affected by network system failures and hacker viruses; the radar ranging method is relatively simple and direct.

[0125] In short, no matter which unmanned driving method is adopted, the catenary track ensures that the car follows the catenary. Even if the wheel steering fails to meet the requirements, considering that the car can drift, as long as the catenary has sufficient stability to resist the inertia of drifting, it will be sufficient.

[0126] (2) Simple remote control driving

[0127] Simple remote control driving mainly consists of a multi-channel GSM remote control switch, a remote control device (such as a mobile phone, computer, remote control, or voice control device), a camera, a communication network (such as a 5G communication network or a WiFi network), etc. The structural characteristics of each component are described below:

[0128] A. Multi-channel GSM remote control switch: For example, one switch controls the throttle motor's forward rotation (fast acceleration), another controls the throttle motor's reverse rotation (de-acceleration), and another controls whether the relay is connected to a high or low voltage, i.e., speed. For greater safety, two GSM remote control switches are required to provide a backup in case of signal problems.

[0129] B. Remote control device: Generally, in an environment without interference, such as at home, you can use voice control, or you can use a computer or remote control to control it. When you are out or in situations where the above three types of control are inconvenient, you can use mobile phone application software for control.

[0130] C. Camera: The main camera is installed at the driver's eyes, and other auxiliary cameras can be installed selectively according to the driver's preference.

[0131] D. Communication network: The above components can be connected together by this communication network.

[0132] Although the remote control is just a switch, it can control the depth, speed, and speed of braking, accelerating, and steering by adjusting the time (inching frequency and interval) and speed level (e.g., speed). For example, the braking commands include: fast brake, slow brake, and back brake; the accelerating commands include: fast acceleration, slow acceleration, and back acceleration; and the steering commands include: turn left, turn right, and return to center.

[0133] When the smart car provided in this application is traveling on other roads without contact networks, it can be simply remotely controlled through the existing 5G communication network. Unlike existing remote-controlled cars, this simple remote-controlled driving does not require expensive lidar and autonomous driving intelligent software compared to existing unmanned autonomous driving technology. It has a low cost, a simple principle, and is easy to implement.

[0134] This application sets up a contact network device on the smart car, which has a reliable and stable structure. It not only allows the electric car to overtake freely, but also provides sensor information of the electric car traveling along the contact network, and can adapt to the swing and bump of the electric car, basically meeting all road conditions for the use of electric vehicles.

[0135] The structure of the contact network proposed in this application is different from that of the contact network of electrified railways and trolleybuses. The structure of the contact network is relatively simpler, low-cost, easy to construct and maintain, and is not prone to generating electric sparks and arc discharges.

[0136] The proposed transportation system's interconnected components involve laying leaky cables along the catenary, while also building a central control center. This allows the central control center to exchange information with the computer terminals of multiple electric vehicles. Wi-Fi can also be used in vehicles, facilitating their electrification and intelligence, ultimately achieving the goal of a connected vehicle network.

[0137] When the transportation system provided in this application is implemented, the main construction process can be briefly described as follows:

[0138] 1. Purchase relevant parts to make the network contact device. First, assemble the telescopic rod, then connect the telescopic rod to the fixed seat slide rail to obtain the network contact device. Then, install the network contact device on the chassis of the existing smart car to make the smart connected car.

[0139] 2. On suitable sections of road in the autonomous driving demonstration zone, construct and install the intelligent connected system (i.e., the connected power supply system and connected information system built in the middle or on both sides of the road along the road), install and connect the power supply, optical cable, Wi-Fi, ultrasonic sensors, etc., and implement the implementation of the connected part.

[0140] To more vividly illustrate the use scenarios of the intelligent connected vehicle provided by this application, the following exemplary scenarios are given below:

[0141] For example, someone in a certain area of City A wants to travel to a certain area of City B. They drive their car, powered by a battery, either by themselves or by a remote control company. Assuming they drive about 5 kilometers to a location in City A where a catenary system is installed, the car's contact mechanism automatically or controlledly extends when it reaches within 1.5 meters of the catenary. The electromagnetic latch locks the car to the neutral line of the catenary through a larger-than-large latch. The latching action provides a switching signal, releasing the electromagnetic clutch mounted on the mounting bracket and activating the rotating mechanism. The mechanism rotates 90 degrees, activating the electric actuator. After reaching the top, it rotates 90 degrees back, retracting the actuator about 12 centimeters via a limit switch, allowing the graphite contact shoe to engage the live line. This controls the relay, recharging the car and replenishing the consumed energy. At this point, the driver can drive themselves (less hassle-free) or hire a cloud-based driving service for a lower fee. During driving, if there are no other vehicles ahead, the car can accelerate to 300 kilometers per hour. Before arriving at an exit in City B, the electric push rod in the contact network device is pushed out 12 cm, rotated 90 degrees, retracted again, and then rotated 90 degrees. Then the electromagnetic latch lock is opened and the clutch is closed. The telescopic rod retracts, leaving the contact network, and then the contact network device is retracted into the car, and finally reaches the destination.

[0142] Compared with the existing technology, the solution provided by this application has at least the following advantages:

[0145] 3. The touch-network device provided in this application is installed on a smart car and connected to the intelligent network system built on the road, forming a transportation system as a whole. When the car is traveling on a road with intelligent network system facilities, the intelligent network system provides electricity and basic sensor information, so that the car can be driven by people or automatically drive forward; when the car is traveling on a road without intelligent network system facilities, it is powered by a battery or internal combustion engine, and can be driven by people or provided with information by a simple remote control driving system, so that the car can move forward, solving the problems of electric vehicle charging, endurance and automatic driving application.

[0146] 4. The smart car provided in this application is an intelligent connected car. It adopts the contact network device provided in this application, which can provide sensor information for its automatic driving along the contact network, and can also adapt to the swing and bump of the electric car. The structure of the contact network in this application is also different from that of the electrified railway and trolleybus. The structure is relatively simpler, low-cost, easy to build and maintain, and not prone to generating electric sparks and arc discharges.

[0147] 5. In the intelligent network system of the present application, leaky cables are laid along the contact network, and a central control center is built at the same time, so that the central station can exchange information with the computer terminals of multiple electric vehicles, and WiFi can also be used in the car, which is conducive to the electrification and intelligence of the car, thereby achieving the purpose of vehicle networking.

[0148] 6. In the intelligent connected system provided by this application, an ultrasonic radar ranging system is laid out along the contact network. Based on the number of the ultrasonic radar sensor where the running car is located, not only the running position of each car can be known; but also the running status of other cars in each lane in the urban area can be known, thereby drawing an operating status map. People can use this map to know where there is congestion and where there is smooth traffic, thereby promoting the development of smart cities.

[0149] 7. The intelligent connected vehicle provided in this application is low-cost and light-weight, and the battery only requires one-fifth of that of existing electric vehicles. The cost is similar to or even lower than that of fuel vehicles.

[0150] 8. The intelligent connected system in this application has a power supply function, and the investment per vehicle or per kilowatt is about 50% lower than that of the charging pile system.

[0151] 9. The cooperation between the intelligent network connection system and the contact network device in this application enables the car to charge while driving. Generally, there is no need to stop for charging. The driving range can be unlimited in a specific area, and there is no need to worry about charging. When leaving the contact network and driving on other roads, the battery is generally full.

[0152] 10. Through the construction and use of the intelligent network connection system in this application, network intelligent unmanned driving can be easily realized at low cost.

[0153] 11. When the intelligent connected vehicle in this application is traveling on a road with a contact network, it has a strong overload capacity, fast acceleration, high speed (it can reach high-speed rail speed on ideal sections), and is safer.

[0155] 13. The intelligent connected vehicle provided in this application is a major change to fuel vehicles and an important guarantee for the sustainable development of mankind. It surpasses fuel vehicles in terms of cost-effectiveness. At the same price, it has the advantages of strong power, quietness, fast acceleration, convenient electricity use, environmental protection and energy saving.

[0156] 14. The intelligent connected vehicle provided in this application is an evolution of existing electric vehicles. This product solves the rigid demands of ordinary consumers for the price, safety, charging, endurance, service life (residual value) and other aspects of electric vehicles. Its market is very broad. It can be an electric car, an electric truck, an electric commercial vehicle, etc., and it also reduces dependence on lithium resources.

[0157] 15. The intelligent connected vehicle provided in this application is an evolution of the original intelligent connected vehicle.

[0158] In summary, this application provides a contact network device that can overcome the shortcomings of side current collection. It can be installed on a smart car and connected to the intelligent network system built on the road. As a whole, a new transportation system can be built.
