Among various driving assistance technologies, not only cruise control or rearview cameras, active distance control cruise systems, lane keeping and change assist systems, advanced emergency braking systems and active front-wheel steering systems are all part of the driving assistance technologies. The system is realized through the intelligent combination of MEMS inertial sensors and perception systems such as cameras, radars or optical radars. The automatic assisted navigation driving function is not a required option in Tesla cars. Data chart of the automatic assisted navigation driving function in Tesla. On June 13, a Tesla Model 3 was driving at high speed on the busy 405 Highway in Los Angeles. , the driver actually fell asleep, and the car drove at least 30 miles under automatic driving. Then the driver next to him called the police. However, the police did not arrive until the Tesla exited the 405 Freeway, so they took a video and posted it on social media, which attracted the attention of netizens. Not long ago, Tesla launched the automatic assisted navigation driving function to Chinese car owners. This function allows the vehicle to complete functions such as automatically changing lanes to overtake, enter and exit ramps on the highway based on navigation routes. The automatic assisted navigation driving function is called Navigate on Autopilot in English, or NoA for short. This function can autonomously complete operations such as lane changing, overtaking, and automatic entry/exit of ramps under the driver's supervision. It is worth mentioning that the automatic navigation-assisted driving function is a feature of Tesla's FSD (fully autonomous driving capability), and FSD is an optional part of Tesla models. The optional price is 56,000 yuan. If it is not selected, Tesla owners equipped with this configuration will currently not be able to drive with Auto Navigation. Inertial sensors help predict the path and connect that path to obstacle detection. Data map Active distance control cruise technology Among various driving assistance technologies, the active distance control cruise system (ACC) requires more specific experience than the cruise control function. This is because, although traditional cruise control technology can save fuel consumption and make long-distance driving easier, it still has to switch the cruise control switch from time to time based on the speed of nearby vehicles. In order to maintain a safe distance from other vehicles, ACC can adjust the vehicle speed as needed rather than maintaining a fixed speed. ACC mainly uses radar, cameras or lasers to measure the distance to objects. Similar inertial sensors that can enhance ESC (automotive electronic stability control system) can also be applied to ACC. Inertial sensors help predict a path and then connect that path to obstacle detection. A similar inertial device can also feature hill-climbing control, allowing the low-gravity sensor to use the downward direction of gravity to determine the inclination so that the vehicle going uphill will not slide backwards. Active Steering Technology Active Steering is another driver assistance technology that reduces the amount of steering angle change with each wheel turn at higher speeds. This feature can improve the accuracy of highway driving, and the yaw rate sensor can provide information about unexpected situations. The good news is that not only luxury sedans, but also some mid-priced cars are equipped with driver assistance systems. BMW has been launching cars with active steering on the market for quite some time, and Ford's Ford Edge also has active steering; I believe other automakers will soon follow suit. Similarly, inertial sensors also use cameras, radars and lasers to assist driving. Technology can achieve autonomous driving by predicting the movement of cars. -------------------------- Author: Sensor information source: Sensor Expert Network Original text: //www.sensorexpert.com.cn/article/1322.html Copyright Statement: This article is compiled and published by Sensor Expert Network.
