In the face of the “internet+†wave that swept the world, the automotive industry is also surging. The automotive driverless technology has been continuously developing, and companies such as Google and Audi continue to make efforts in the driverless area. Another type of technology that is also subordinate to drones is the remote-control driving technology. Just a few days ago, Mercedes-Benz broke out the new E-class will have remote parking, today we talk about the car's remote driving technology. The remote control driving technology refers to the fact that the driver uses a remote control driving controller outside the vehicle within a visual range of 10 meters to safely control the start, advance, retreat, and steering of the vehicle and control the vehicle to run at a low speed, thereby solving the narrow lane picking and narrow lane parking. Narrow lanes and other problems. It is natural to think that remote control driving technology is associated with BYD's sharp sharpness. It can be said that the industry is second to none. In early 2013, BYD announced the launch of its second-generation technology for remote control driving, breaking through technical difficulties and achieving simultaneous steering and movement operations. In fact, remote control driving technology has a long history. In real life, we can actually feel this technology, ranging from children's remote control toy cars to military drones. In general, remote control driving technology can be divided into radio remote control, infrared remote control and ultrasonic remote control from the carrier of the propagation signal. Infrared remote control technology Infrared remote control technology is widely used in daily life, and TV remote control is one of them. The use of infrared technology to transmit signals has a low threshold, simple structure, and low cost. However, the disadvantages are obvious. First of all, it is easy to be blocked, poor penetration ability, short-distance distance, and easy to be disturbed when the sun is strong. Therefore, it is generally suitable for indoor use in such a short distance environment. Ultrasonic remote control technology Ultrasonic technology is similar to infrared, and the remote control distance is also short. However, strong directionality is a major feature of ultrasound, and radioactivity is excellent at different interfaces. Common reversing radar is relying on ultrasonic ranging. Therefore, the reflection characteristics of ultrasonic waves are generally used, and they can also be used to detect distances, water depths, and the like. Radio remote control technology The radio remote control has a long remote control distance with respect to the first two technologies, and has no directionality and the advantage of being able to penetrate obstacles. However, radio remote control devices are relatively susceptible to mutual interference, and the solutions are generally differentiated by using different carrier frequencies and identification codes. Regardless of the carrier used to transmit signals, the basic components of a set of remote control devices include transmitters (remote controls), receivers, and servos. Although most of us are remote control technologies that we know from home appliances and remote-controlled toys, we may feel that it is of no importance. In actual fact, remote control data is an important piece of information and must meet four criteria: confidentiality of information, prevention of illegal disclosure of information, integrity of information, protection against unauthorized modification, availability of information, prevention of illegal detention and reuse, and controllability of information. Meet the requirements of legal monitoring. BYD Remote Control Driving Technology BYD can be said to be the pioneer in remote-control driving technology. In August 2012, with the launch of Su-Rui, the world's first car to use remote control technology to achieve unmanned and put on the market was born. At the beginning of the debut, there were many netizens who questioned the security of this technology. First of all, the speed of the vehicle is very low, from the initial design of 5 km/h to 2 km/h, which is slower than walking. SpeedRider's remote control driving technology relies on radio waves to transmit, and the remote control transmitter frequency is 315MHz. 315MHz is the frequency adopted by currently used car central locking remote controllers. Transmission through this frequency saves research and development costs and is also in line with the country's limitations on the frequency of remote controls, but the anti-jamming capability may have a slight effect. In September 14th, BYD announced the new G5. The car was BYD's definition of “Smart Car Based on Internet Thinkingâ€. At the same time, “driving without driverâ€, which represents the future development direction of the automobile, also appeared in this model. In the remote control method, as long as the owner downloads a Bluetooth key APP on the mobile phone, the mobile phone can become the key of the vehicle. Through the mobile phone APP, the owner can complete the remote control driving within 30 meters outside the vehicle. Land Rover Mobile Phone Remote Control Car Technology In June, Jaguar-Land Rover released the newly developed autopilot technology and also announced for the first time a remote-controlled Range Rover Sport R&D vehicle. The driver can control the entire process of the vehicle from outside the car through a smartphone. The smart phones have control functions that include steering, acceleration and braking, and adjusting the height of the vehicle. These features allow the driver to use the mobile phone to control the vehicle outside the vehicle and safely drive it away from complex road conditions at a speed of no more than 6.4 kilometers per hour, even through severe off-road terrain. In addition to leaving the parking space, when the vehicle is on complex off-road roads, across a stream, or across ice and snow, the driver can also get himself out of the car as a vehicle guide, which can effectively avoid some invisible obstacles and reduce collision avoidance. Danger. The information released by the factory shows that the activation of the remote control function requires that the distance between the controller and the vehicle is within 10 meters, and that the smart key is effectively recognized. If the driver is too far from the vehicle or may be in danger because of a short distance, the system will automatically brake the vehicle to ensure safety. Land Rover’s newly released prototype autopilot also includes a “multi-point steering†function. That is, the vehicle can autonomously complete a 180-degree turn on the road, so that the front of the vehicle is facing in the opposite direction, so that the vehicle can free itself from the most unfavorable road conditions, such as encountering dead ends or in a crowded parking lot, and of course, assisting the driver. Finish what they are not good at. The new BMW 7 Series is also equipped with remote parking. Mainly through the smart key to complete, in the process of enabling the remote parking function, the vehicle can automatically brake, and can achieve a maximum of 10 degrees of steering angle. As long as the button is pressed, the vehicle will automatically stop in the garage or leave the garage according to the position judged by the radar. The latest explosion of the new generation of Mercedes-Benz E-class will also be equipped with mobile phone remote parking features, and the new BMW 7 Series with a display of the key remote parking is different, the new Mercedes-Benz E-class is also a special APP for smartphone remote control. Including forward, backward and steering can all be controlled by APP. Ford develops remote control technology for vehicles As a veteran car manufacturer in the United States, Ford is not to be outdone, testing a car remote control technology based on 4G LTE connectivity. Owners can remotely control vehicles thousands of kilometers away, much like a terrestrial version of a drone. In Alchi's work room, there are three monitors, a racing game steering wheel, and throttle, brake, and clutch pedals. When you sit in this cockpit, you can see that the screen shows a golf cart as far away as 2,400 miles away. A picture of advancing in a parking lot in Atlanta, United States. Ford still believes this technology will be one of the options available for future transportation modes. Because some consumers may not be willing to give the option to the on-board computer when the vehicle crosses the intersection (as a matter of fact, when Ford conducted this experiment, people were also scheduled to stand on the test site so that the connection could be accidentally disconnected. Manual intervention. And this technology is much cheaper than autopilot. Moreover, these sensors can be easily installed in existing models. In addition, this remote control technology can be based on the existing 4G LTE network connection, except that there will be a slight delay in the network speed during peak traffic. “This is actually a real-world application of network connectivity. I can't say that this technology is now mature, but it can be said that the results of this experiment have given us great confidence in making full use of existing infrastructure.†Ford’s vehicle electrification and infrastructure worldwide Director Mike Tinskey said. Ford said that he himself envisions several aspects of the application of this technology in the future. For example, a car rental company can use this technology to remotely control the location of vehicles moving in a parking lot, and car sharing services can reasonably allocate vehicle resources in the case of an excess vehicle in a certain area. You can enjoy your own generation without additional payment. Car parking service, at the same time, you can also use this method to drive remotely for elderly parents during holidays. Use remote control to drive out "loss" ideas As early as 2012, a pair of drunk men and women controlled cars drove on the road and were stopped by the traffic police. The two did not admit drunk driving, claiming that they were only on the remote control car, not in the car, and not touching the steering wheel. The female breasts were even more blatantly insensible and exposed breasts. They attracted crowds of people. Finally, the policemen were poor and unable to release them. Due to legal loopholes, the “drunken drunk†incident of the returnees caused a great uproar in the society. Coincidentally, on the early morning of the day in 2013, a woman fled the parking fee to facilitate driving a car with a remote control approaching the toll booth. When the toll collector was in close view, the driver's seat was empty. At this time, the woman slowly climbed the roof from behind the car. The toll collector mistakenly believes that he has encountered a female ghost. After the toll collector ran, the woman slipped into the toll booth and put away the crossbar. Then she drove away the car.
