Mercedes-Benz held a briefing on the road test of driverless cars in Japan on April 14th, stating that Mercedes-Benz will realize automatic parking in 2015, by 2020 Achieve unmanned driving on the highway.
In fact, Mercedes-Benz has carried out the driverless test on the “Bertha Benz Memorial Route†as early as August 2013. The experimental car S500 INTELLIGENT DRIVE has completed more than 100km from Mannheim to Pforzheim in Germany at 120 km/h, and it The entire process has adopted the autonomous driving technology to pass the test of various complicated road conditions in the city and the suburbs.
"Bertha Benz Memorial Route" is a very historic road for Mercedes-Benz. In 1888, he continued to support his wife Bertha Benz behind his Benz. He drove his Mercedes-Benz car to the grandmother more than 100 kilometers. Before that, no car in the world could travel so far, so this driving became a historic initiative, and Mercedes decided to carry out its driverless test on this road, probably also hope that the test is the same Can be a milestone.
Marc Boderke, vice president of Mercedes-Benz, Japan, said: "In the past, people felt that driverless costs were high, they were immature and they might break the law, but now everyone's concept has changed. Car owners are hoping to encounter traffic jams and other conditions. The vehicle can drive by itself, and then the car itself can do everything when it comes to difficult parking, etc. The young people want to be able to play mobile phones or watch movies while driving, which can only be driven by autopilot. achieve,"
Dieter Zetsche, CEO of Mercedes-Benz Group
The group's CEO Dieter Zetsche said that for Mercedes-Benz, "Intelligent drive" is the key technology that represents the future of Mercedes-Benz. One of Mercedes-Benz's future goals is to keep people away from traffic accidents and achieve unmanned experience.
All of Mercedes-Benz's unmanned core technology has been applied to its new S-Class sedan. The new Mercedes-Benz S-Class and even the new-generation E-Class have been able to achieve autonomous driving to a certain extent, while Mercedes-Benz's driverless car "Mercedes-Benz S500 Intelligent Drive" is an upgraded version of the Mercedes-Benz S500. From a technical point of view, Mercedes-Benz is Driverless technology is quite mature.
Now let's take a look at what technologies have been used in "Intelligent Drive" and what features have been implemented.
Chassis technology
Mercedes-Benz's Intelligent drive system has commercialized the Magic Body Control, which can proactively determine the road ahead and react to it, in the new S-Class. With a stereo camera on the windshield, a car equipped with a Magic Body Control can detect uneven roads in front of the car. The body balance is then maintained by adjusting the damper damping. Let the car be on the road.
Safety at night
The system also uses Night View Assist Plus, which does not rely on heat. Instead, the infrared reflected waves are identified by using multiple sets of illumination systems and cameras, and the identified data is transmitted to the driver in the form of an image relative to the naked eye. Night View Assist Plus captures the details of the darkness more clearly and completely, and is better able to expand the driver's field of vision.
Strong winds cause safety hazards
This system has also updated some techniques. It uses Crosswind Assist to improve the car safety factor. When the vehicle is driving to a strong crosswind section. There is a potential danger of sudden departure from the lane, and the system can perform braking intervention on the windward side wheels of the vehicle through the vehicle stability driving system sensor to counteract the influence of strong winds and reduce the possibility of the vehicle deviating from the lane.
Brake safety factor
In addition to reducing the effects of strong winds, the system also increases the safety factor when braking. Introduced a new brake system - PRE-SAFE Brake. It detects pedestrians and automatically brakes to avoid full collisions at speeds above 50 km/h, greatly reducing the damage of collisions at speeds of over 72 km/h. The upgraded version of Pre-Safe Plus protects the car from damage. The last barrier to the accident. Whether in driving or parking, the radar behind the car is constantly scanning the rear vehicle. Especially in the same way as the car. If the rear vehicle is too close, the brake light automatically flashes high-frequency to remind the rear car to decelerate or brake, and if the rear anti-collision is unavoidable, the system activates the passenger protection mechanism.
Traffic intersection accident
For accidents with traffic speeds of up to 72 km/h, the system introduces the BAS PLUS With Cross-Traffic Assist (Enhanced Brake Assist with Cross-Traffic Assist) when the detection system senses the direction of travel through the camera and radar. When there is a cross-flow, and a collision may occur, the owner will be warned by both sound and visual warnings. Usually, the owner will only step on the brakes in a preventive manner. At this time, the BAS PLUS system will automatically increase the braking force or even the full force. Brake to ensure the safety of the vehicle. However, this system can only work at speeds of 72km/h or less, but generally no one will cross the road at a higher speed. In 27% of the time. This system is effective in preventing accidents and collisions.
Anxious discomfort
When driving, the owner of the vehicle has a corresponding solution to the anxiety discomfort caused by the constant adjustment of the distance from the front vehicle. The Distronic Plus with Steering Assist is the Distronic Plus with Steering Assist. This system automatically judges the road conditions based on the data returned by different bands of radar, including the speed of the preceding vehicle, the distance to the preceding vehicle, and intelligently adjusts the safety distance and speed, so the system can still maintain the vehicle in the center of the lane even in small corners. And to maintain a safe distance, the biggest difference from ACC active cruise is that this system does not need to be manually turned on. The system automatically controls the distance and speed as needed, which is especially worth mentioning. In low-speed traffic and even traffic jams, the system does not even need to detect lane markings, as long as it is always in front of the car. The biggest credit of this system is to liberate the car owners to follow the frequent acceleration and deceleration of the car to bring fatigue.
Lane departure warning
In addition to the techniques mentioned above. In addition, the AccTIve Lane Keeping Assist is activated for lane departures. The ApapTIve Highbeam Assist Plus is composed of more than 100 small LED tubes - capable of being in front of the vehicle. It seems that it is absorbed by the light before it does not affect the line of sight, avoiding glare to the vehicle ahead. At the same time, the system also has "Radar Safety Package" (including Distronic Plus automatic ranging system and Brake Assist Plus brake assist system and Blind Spot Assist blind spot detection system and Lane Keeping Assist lane keeping system and other safety equipment) and through the body Four cameras implement technologies such as 360-degree panoramic camera functions, and these technologies are currently on many models of Mercedes-Benz.
The US Department of Road Traffic Safety (NHTSA) divides the legal level of driverlessness into four levels according to the degree of automation of driverless vehicles. The current unmanned vehicles that can achieve multi-faceted automatic control are still at a semi-automatic level, and the accident liability during driving is also carried out in accordance with the current road traffic laws, while the German Federal Highway Research Institute (BASt) will drive automatically. Technological development is divided into three phases – partial autopilot, highly automated driving and ultimately fully automated driving. In some autopilot stages, the driver still needs to continuously monitor the vehicle's automatic assistance system prompts. The vehicle is unable to make autonomous movements; it is highly automated. The driver no longer needs to continuously monitor the system. The electronic assist system can temporarily replace the driver in certain situations to make certain actions, and the driver can take over the control of the vehicle at any time; and the fully automatic driving phase is somewhat similar to the real "unmanned" state.
Nowadays, it is the positioning, mapping and traffic signals that affect the complete automation of driverless cars. In order to achieve automatic driving, it is necessary to obtain accurate lane line position, signal position, crosswalk, stop line and other information to realize the socialization of driverless driving. In order to popularize unmanned vehicles in the future, map data collection will become an important one. ring.
At present, Mercedes-Benz's mass production vehicles on the market have already achieved partial autopilot. At present, Mercedes-Benz has introduced the Distronic Plus (Enhanced Distance Control System) for low-speed unmanned driving and maneuvering functions such as front and rear left and right directions when introducing traffic jams on the latest S-Class and E-Class vehicles, and according to Mercedes-Benz. The company will introduce the upgrade technology for driverless cars into the C-class models in the future.
Japan's Toyota Nissan, Honda and other traditional large auto manufacturers have announced their pilot cars, while large-scale automakers such as Audi and GM/Volvoford in Europe and the United States have also realized the development of their own driverless cars. The road is measured. As an IT company, Google first announced its own development of driverless cars. And 800,000 km of safe and accident-free road testing has been achieved.
There are many ways to achieve unmanned driving, and Mercedes-Benz's vision of unmanned driving is not only relying on communication between vehicles, vehicles, and roads, but more consideration is based on high-precision image maps that can be applied to automobiles. Autonomous driving - that is, relying entirely on image maps to achieve positioning, and then grasp the surrounding environment through various sensors. Thereby assisting and correcting the unmanned driving of the vehicle.

Mercedes F015 luxury driverless car in the future movie
Mercedes-Benz F015 Luxury in MoTIon offers an innovative perspective on future automotive mobility. The overall shape is sci-fi, with a low front end and a front window that extends even more to the smooth roof.
After knowing the number of passengers, the car can decide to open several doors at its discretion. When in the autopilot mode, the car's LED lights emit blue light. And if someone is manually manipulating, the light will turn white.
Under a technologically savvy look, the F015 uses a combination of cameras, sensors and LED lights to navigate and respond to the presence of pedestrians and other vehicles. Depending on the traffic conditions, the LED lights in the parking space can display prompts such as "slow" or "stop". When a pedestrian is discovered, the car will also project a laser zebra crossing on the ground and use a soft voice and an indicator arrow to encourage the opponent to pass.
The internals of F015 fully take into account the user's need for privacy. After opening all four doors, you will find a spacious interior with wooden floors, smooth white walls and leather lounge chairs. These chairs are all egg-shaped, with a high backrest and an aluminum alloy.
When you fasten your seat belt and close the door, you will see that each back of the door and the back wall of the car are equipped with a 4K resolution touch screen, even the dashboard below the windshield Support for touch and gesture control.
When there is no need to control the car, the front seat passengers can turn the seat to the rear for more direct communication with the passengers behind.
After the vehicle is started. The F015 doesn't feel like the top-end Mercedes Benz, but more like a luxury monorail.
The car's window glass is opaque and has a higher position than the average car. Obviously, Mercedes-Benz hopes that the touch screen in the car can become the focus of the user's attention, not the situation outside the window.
At present, Mercedes-Benz F015 can reach the driving speed of 200 km / h, Mercedes-Benz selected a unique power system - hydrogen fuel cell for F015. In an ideal situation, every 200 kilometers required to charge once, the endurance seems to be insufficient to meet the needs of users.
Recently, the Mercedes-Benz F 015 came to San Francisco, USA, and tested it on the road, and announced a large number of real shot pictures.
It is reported that F 015 is 5.22 meters long, more than 2 meters wide, 1.5 meters high and 3.6 meters in wheelbase.
The futuristic silver streamlined look looks futuristic and attracts a lot of passers-by.
There is no doubt that the Mercedes-Benz F015 presents a more futuristic autonomous car form, which is worthy of recognition. After 15 years, perhaps it will change the way people commute.
