In the future, the importance of driver assistance systems will increase significantly. Audi engineers are committed to developing a variety of different solutions designed to make driving easier and safer. The new system will create more convenience for the driver while preventing accidents or at least reducing the consequences of the accident. This article refers to the address: http:// Audi is working on a range of innovative solutions involving sensors, sensor control and inter-module interaction. At the same time, networking interactions between cars and infrastructure and other transportation participants will become very important, and the technology related to this is called "Audi connect" by Audi. Audi's ultimate goal is to create smart cars that are completely immune to accidents. Traffic jam assist The traffic jam assist system is a technology that can share the driver's work when driving has no fun, such as slow driving or full congestion. When the speed is in the range of 0 to 60 km / h, the system helps the driver to control the autonomous steering, acceleration and braking under certain limits. Whether it is highway or urban traffic, as long as the route is not too complicated, traffic jam assistance can be used. Based on an adaptive cruise control system with stop & go function, the system adds a new component for side guidance, and the three sensing systems work closely together. The two latest generation radar sensors cover a 21 degree viewing angle and a sector area within 250 meters. A wide-angle camera is responsible for monitoring lane markings and detecting other cars, pedestrians or guardrails. Eight ultrasonic sensors monitor the front and corner areas of the car. These data are mainly used to maintain a safe distance and complement the information obtained by the camera. If the ACC adaptive cruise function is turned on, the traffic jam assist function will continuously analyze the speed of the car and other vehicles around it. This function can only be used when the vehicle speed is below 60 km/h or when the data indicates that the traffic is in a congested state. If the driver activates the function by pressing the button, the traffic jam assist system will take over the partial control. Under the control of the traffic jam assist system, the "corridor" of the car will be significantly wider than a normal lane, which makes the car and the front car have a certain offset. Because, once it is necessary to make room for emergency rescue vehicles or need to bypass obstacles, the system can also control the vehicle to continue. Here is one of the advantages of the radar sensor: not only can the front car be monitored, but also the vehicle before the car is detected, and the design path is calculated by data. When accelerating and braking, the traffic jam assist system behaves exactly the same as the ACC system and can also react to parallel vehicles. Automatic full brake In the last few meters before the collision, many Audi cars can achieve self-braking when the driver is powerless. At present, Audi is working on further development of this function to target both the pre sense city and the intercity traffic. Pre sense city In urban traffic, the automatic full-force braking system is based on innovative small sensor technology. A few years ago, Audi played an important role in the development of this technology. The PMD sensor (PMD = optoelectronic hybrid) is a small chip that can measure three-dimensional distances more accurately than traditional sensor systems. The advantages of PMD technology that has been successfully applied to entertainment electronics over other sensor systems are not limited to their packaging form. Its picture blender detects moving and stationary targets, working in the dark, in the rain or in the bright sunshine. The pre sense city system warns the driver with a short brake when the speed is below 65 km/h and the accident of the rear-end vehicle is about to occur. If the driver does not respond, the system will fully brake approximately 1 second before the collision, reducing the impact speed to 30 km / h. Another important function of the pre sense city system is the protection of pedestrians. The PMD sensor detects objects and pedestrians within 20 meters. If the sensor reports a dangerous situation, such as a pedestrian walking on the road, the system will determine if it is necessary to perform full braking. If necessary, the system will also fully brake approximately 1 second before the collision. It can reduce the impact speed by up to 30 km/h. This means that in some cases, the car can stop in time. Pre sense city Preventive overall safety technology provides excellent protection for pedestrians and cyclists. At the same time, this intelligent system can also provide good protection for passengers on the car during the rapid deceleration. Active emergency braking Audi is developing a pre sense system that can brake at full speeds of over 65 km/h. The core is a laser scanner that offers a wider range, wider field of view and higher precision. The laser can take advantage of its wide field of view to scan the area on the front and sides of the car, so it can also monitor buildings and other conditions on both sides of the vehicle. If there are obstacles ahead, such as the sudden discovery of the front of the traffic jam, the system can assess whether the driver still has the opportunity to take evasive behavior. If the opportunity to avoid has not existed, the system will promptly warn and automatically start full braking when necessary. Even if the driver is unable to respond on his own due to other reasons such as illness, the system can automatically and significantly slow down, greatly reducing the severity of the accident. This makes it possible to avoid high-speed collision accidents by braking under certain conditions. Active belt buckle Audi is also constantly optimizing its on-board restraint system. The rear passenger active belt buckle, driven by a small electric motor, will likely become an innovative technology of the future. When the rear door of the Audi car is opened, the active safety buckle will protrude a few centimeters upward from the seat cushion to facilitate the passenger to fasten the seat belt. After that, it will return to its original position. In the event of an imminent collision, the active belt buckle will move slightly downward to tighten the seat belt. This process is reversible. Audi's adaptive restraint system will be more closely networked in the future with a new set of assistive technologies. Forward-looking sensors such as PM diodes typically identify potential accident hazards a few seconds before a collision occurs, while assessing the speed and size of the other vehicle. The adaptive seat belt force limiter and adaptive front airbag will be activated based on this information, allowing both systems to better protect passengers than they are now. Intersection assist Many traffic accidents occur at intersections or road junctions and often have very serious consequences. Side impact is the second most common cause of traffic accidents in Europe. Audi is working on the development of intersection assistance systems designed to prevent accidents or at least mitigate the consequences of accidents. The intersection assist system uses two radar sensors and a wide-angle camera to scan the front and sides of the car. Among them, the radar sensor data plays a major role, and the camera provides reference data. If the sensor detects that a car is coming from the side, the system will issue a warning and notice to the driver at different levels. Audi is also developing additional auxiliary systems as an extension of the intersection-based system based on sensor technology. It is based on car-x technology, specifically, the system is based on radio links between two vehicles that may have an accident. At some intersections where accidents occur, reporting the status of traffic lights through a modem is another possibility. According to the car WLAN (Wireless Local Area Network 802.11p) standard, these data transmissions can be done by radio. Although far from being widely used, car-x technology has many advantages, including when the intersection sensor's line of sight is blocked. The technology can cover a large distance and transmit detailed information of the car, so that the airbag can be adjusted according to the weight of other cars. The combination of car-x technology and on-board sensors can greatly improve safety. Parking guidance Small vertical parking spaces, garages for motor vehicles/non-motor vehicles – parking spaces are often very compact, and it is difficult for drivers to get off the bus after parking. It is also possible to damage the doors when opening the door. Parking guidance technology will solve these problems as an auxiliary system for Audi's future. With the technology from the Audi prototype, the driver can get off the garage before parking and then issue commands via a wireless key or smartphone to let the car complete the parking itself. With the help of an ultrasonic sensor, the car will automatically stop in the parking space or garage. If the system detects an obstacle, it will stop immediately. When the final position is reached, the system automatically shuts down the engine, closes the ignition key door and the door, and finally sends a confirmation message to the driver. Reversing warning system Reversing from a vertical parking space is often tricky. The driver can't see the traffic situation behind the car, and can only be forced to drive with caution and "feeling". Another future solution from Audi – the reversing warning system will simplify the process. The system uses two Audi side-assisted radar sensors mounted at the rear of the vehicle to measure, evaluate distances, speeds, and possible travel paths of detected vehicles, and inform the driver of possible collision risks. Open the door warning The get-off warning system also utilizes the Audi side-aided radar sensor. This is a great help for getting out of the car when the line of sight is limited. When the occupant tries to open the door, the system will check if there is a car or bicycle coming close to the car. In dangerous situations, the system will warn the occupants through the bright light signal at the door and accompanying the sound signal. In addition, Audi plans to inform the occupants of the danger through tactile warnings. Trailer assistance The Trailer Assist System is a future technology that supports reversing when a vehicle is towing a vehicle. The system automatically performs steering control, reducing the burden on the driver to constantly correct the steering. The system uses the sensors on the trailer hitch for steering control, ensuring that the swing angle between the tractor and the trailer remains stable. The driver does not need to use the steering wheel to control, but more to use the large knob of the MMI control system. The trailer assist system must operate within the specified speed range to prevent the tractor from colliding with the trailer by limiting the maximum swing angle. The system can also be automatically adjusted to the size of the trailer. We specialize in Cable Assembly overmolding.
