Audi has been introducing advanced technologies to its vehicles to improve driving safety and portability. Here are some important aspects of ADAS technology in Audi:
① Audi Pre Sense system: Audi Pre Sense is an advanced safety system that detects potential collision risks. It uses radar, cameras and other sensors to monitor the road ahead and traffic conditions. When the system detects a potential risk of collision, it can automatically take actions, such as emergency braking, emergency braking preparation and seat and window pretensioning, to mitigate the effects of a collision.
② Audi Adaptive Cruise Control（ACC): ACC is an intelligent cruise control system that automatically adjusts your vehicle's speed based on the speed and distance of the vehicle ahead. This system makes driving easier, especially on the highway, as it helps you maintain a safe distance between vehicles and reduces driving fatigue.
③ Audi Lane Keeping Assist：The Audi Lane Keeping Assist system uses cameras to monitor your vehicle's position on the road to ensure it stays in the correct lane. If the vehicle begins to deviate from its lane, the system will alert the driver with slight directional intervention or a vibration warning to avoid unintentional deviations from the road.
④ Audi Traffic Jam Pilot: This is a type of autonomous driving technology that allows vehicles to drive autonomously under certain conditions, such as traffic jams. On supported roads, Traffic Jam Assist can control the vehicle's acceleration, braking and steering to reduce driver stress in traffic jams.
⑤ Audi Park Assist：Audi's Park Assist system can help drivers perform parallel and perpendicular parking, even in tight spaces. This system uses sensors and cameras to detect parking spaces and then controls the vehicle through an automated steering wheel, making parking easier.
In short, Audi's ADAS technology is constantly developing to improve driving safety and convenience. These systems combine sensors, cameras and advanced software to ensure that drivers can operate their Audi vehicles more easily and safely on the road. Through continuous innovation and improvement, Audi provides drivers with more support and confidence, giving them better control in different driving situations.
The accuracy and reliability of ADAS systems are critical to vehicle safety and performance. Here are some situations that may cause ADAS systems to need to be recalibrated:
① Vehicle collision:
Once the vehicle suffers a collision, especially at the front or side, the sensors and cameras of the ADAS system may be damaged. The damaged sensor or camera may prevent the system from accurately recognizing its surroundings, reducing its functionality.Recalibration is necessary to ensure that sensors and cameras are positioned correctly and provide accurate data.
② Parts replacement:
When parts involving the ADAS system need to be replaced, such as the front bumper, front windshield or sensors, recalibration is often necessary. The installation of new parts may cause small changes in sensor position, affecting the accuracy of the system. Recalibration ensures the new components work in conjunction with other ADAS systems to maintain overall system consistency.
③ Maintenance and adjustment:
Regular maintenance and adjustments to vehicle components may require recalibration of the ADAS system. For example, tire changes, suspension adjustments, or brake system maintenance may produce small changes in the vehicle's dynamic characteristics, requiring recalibration to accommodate these changes. In addition, sensors and cameras may also require periodic cleaning and calibration to ensure they function properly.
④ Environmental factors:
Extreme weather conditions, especially severe weather such as intense rainfall, fog or snow, may affect the performance of ADAS systems. In these cases, sensors and cameras may become obscured, contaminated, or compromised. This may require system recalibration to accommodate different environmental conditions.
⑤ Software update:
Manufacturers may release software updates for ADAS systems to improve system performance, fix bugs, or add new features. Software updates may affect your system's parameters and configuration, so recalibration may be required to ensure your system is compatible with the new software version. Recalibration is an important step to ensure system accuracy and performance are maintained at all times to improve driving safety and comfort. Vehicle collisions, parts replacement, maintenance, environmental factors and software updates can all cause ADAS systems to need to be recalibrated. Drivers and vehicle owners should pay close attention to these conditions and seek professional maintenance services as needed to ensure the proper functioning of their ADAS systems.
① Check the vehicle: Before performing the calibration, the technician will check the overall condition of the vehicle to ensure that it has no obvious damage or problems. If there are any issues, such as collision damage or worn parts, they will be repaired or replaced first.
② Prepare tools and equipment: Technicians need to prepare appropriate tools and equipment, including calibration equipment, laser rangefinders, calibration plates, computers and software to perform the calibration process.
③ Position the vehicle: The vehicle is usually positioned in a specific area to ensure that it does not move during the calibration process. This can be achieved with vehicle position markers or brackets.
④ Calibrating sensors: During the calibration process, various sensors, such as cameras, radars and laser sensors, will be calibrated to ensure that their angles and positions are accurate.
⑤ Adjust parameters: The technician will access the vehicle’s control unit and use specific software to adjust the parameters of the ADAS system to match the results of the sensor calibration. This ensures consistency between the sensor and control unit.
⑥ Road test: After completing calibration, the vehicle usually needs to undergo road testing to ensure that the ADAS system operates normally under actual driving conditions. This covers a variety of driving situations, including highway driving, city driving and parking.
⑦ Confirm calibration: Once the road test is successfully completed, the technician will verify the accuracy of the calibration and ensure that the performance and accuracy of the ADAS system are up to standard.
It should be noted that the AUDI ADAS calibration process may vary depending on the vehicle model and specific ADAS technology. Calibration usually needs to be performed by trained professional technicians to ensure the accuracy and safety of the calibration. This helps ensure that ADAS systems provide accurate information under various driving conditions, thereby improving driving safety and convenience.
