We are not unfamiliar with intelligent driving technology. Commonly, ACC adaptive cruise, lane departure warning, etc. are within its scope. With the upgrading of consumer demand and the development and innovation of automobile technology, intelligent driving has become the focus of attention of major car companies.
At present, the level of intelligent driving of various car companies is uneven.The Audi A8 claims to be able to achieve the highest level of L3 autonomous driving. Tesla said that its L2.5 level of autonomous driving is mature, and some companies abandon L3 and directly develop L4/L5 level automatic driving.
In the face of the divergent car market, how can we easily and quickly understand the level of intelligent driving technology for a car? What kind of car is the future “potential stock”?
Speaking of the test drive experience, recently, a “new player” that deserves attention has appeared in the new energy vehicle industry, and it is the high-end smart new energy vehicle brand ARCFOX . In terms of intelligent driving technology, the emphasis is on people-oriented, its first mass-produced high-end intelligent pure electric SUV, ARCFOX αT, is equipped with intelligent driving technology developed in cooperation with Bosch. The highest level of automatic driving is between L2-L3, and in some scenarios Down (driving on highway) can achieve L3 level.
It is worth mentioning that even with advanced intelligent driving technology that can meet the driving needs of current car consumers, car companies must remind consumers to stay vigilant and pay attention to road conditions during driving.
I believe many people will also ask, if they encounter a car of their choice, what is the core device that best reflects their intelligent driving technology? What are the criteria for judgment?
Sensors are the key to smart driving technology
In layman’s terms, vehicle sensors are equivalent to human vision and touch, and are the key to obtaining all internal and external information, including clear driving information such as road conditions, other vehicles and the status of the driver, and intuitive human-computer interaction. At present, the sensors of intelligent driving assistance systems are mainly divided into two categories: cameras and radars.
The working principle of the camera is to judge the road conditions by the scene projected on the surface of the image sensor. The judgment of its pros and cons is relatively simple. In the case of similar clarity, the more the better the principle. For example, the α-Pilot driver assistance system equipped with ARCFOX αT uses up to 23 latest-generation high-performance environmental sensing sensors that have been deeply cooperated with Bosch, including one third-generation multifunctional camera and four second-generation surround view sensors. Camera and an infrared camera for facial recognition in the car.
Vehicle radars are relatively complex. The mainstream radar types include ultrasonic radar, lidar, and millimeter wave radar. Each type of radar has different functions.
One of the most practical is millimeter wave radar, which uses the frequency difference caused by electromagnetic wave reflection to measure distance. Short-range millimeter wave radar can be used for blind spot detection, collision warning and collision avoidance, and long-range millimeter wave radar can be used for adaptive cruise and active Brakes etc. The longer the distance measurement, the higher the accuracy, the faster the transmission, and the less affected by the weather, can we receive more and more accurate information and reflect the higher the level of intelligent driving. For example, ARCFOX αT is equipped with five fifth-generation millimeter-wave radars, which can provide a detection range of up to 210m, a maximum field of view of ±75° and higher detection accuracy.
The frequency of ultrasonic radar is low and the transmission speed is slow. It is mostly used for low-speed parking and reversing, that is, common reversing radar. In this regard, ARCFOX αT is equipped with 12 sixth-generation ultrasonic sensors; Lidar is generally installed on the roof or body of the car. The surrounding area has high processing accuracy and large data volume, but the cost is too high. 5G has not yet been popularized and most of its own is in the experimental stage. Lidar is rarely installed on general production vehicles.
As mentioned at the beginning of the article, the current level of intelligent driving technology is uneven. Before the realization of fully autonomous driving, what is the significance of assisted driving technology?
The continuous innovation of assisted driving, the biggest benefit to us is not to liberate our hands, but to focus on improving the driver’s driving experience, through advanced automotive electronic technology and artificial intelligence methods, to bring clear driving information and intuition to the driver Human-computer interaction and intelligent driving assistance. At the same time, it can also provide an attempt to build a driving space in the future autonomous driving environment.
