Today, with the rapid iteration of the domestic new energy vehicle market, many manufacturers at home and abroad are aiming at this huge cake, and taking advantage of this so-called "new energy" momentum, they have launched one model after another. From the product point of view, although there are many new energy vehicles on the market at present, the quality is actually mixed, and there are not many "good cars" that can really be taken. At the same time, many manufacturers also regard the L3 automatic assisted driving system, which is popular at present, as a configuration to check for missing parts.
This technology configuration is no longer exclusive to luxury cars, although 200,000-300,000-level household scooters are also equipped with this configuration; But to be honest, many friends who have bought cars don’t know what L3 is. Whether it is even practical is still unknown; Today, on the occasion of this test drive of Ai ‘an LX, we have a deep talk with you about the ADiG0 3.0 autopilot system carried by this car.
What is L3 autopilot? What’s the difference between ADiGO 3.0 system?
First of all, briefly talk about L3 autopilot, which is based on the standards formulated by the American Society of International Automotive Engineers. Among them, L3 level is the abbreviation of highly automatic driving when conditions permit, and the car can turn, accelerate and decelerate by itself and respond appropriately to the environment; At the same time, people can also take over and quit autonomous driving. To put it bluntly, L3 automatic assisted driving has been able to get rid of the hands and feet, and there is no need to interfere with the driving of the car in the open state. The ADiG0 3.0 autopilot system equipped by Guangzhou Automobile New Energy Ai ‘an LX, the most important thing is to improve the high-precision map and the more intelligent Mobileyeye EQ 4 camera, which can more accurately perceive the 360-degree environment of the vehicle.
Among them, the difference between this ADiGO 3.0 autopilot system and other assisted driving systems lies in this "high-precision map", which is considered to occupy a unique "geographical position". Compared with other maps in the past, its accuracy has reached 0.1 meter, and it can predict the road conditions 1 kilometer away, which greatly improves the perception of vehicles as a whole. However, the GPS signal is lost due to high-speed road conditions, under the bridge and the weather, and the latest generation MobileyQ4 chip carried by this Ai ‘an LX will not appear, greatly improving the driving experience of the car.
At the same time, ADiGO3.0 system uses the fifth generation millimeter wave radar from Bosch to cooperate with the brand-new high-precision map; Moreover, the system also has the self-learning ability, which can imitate and evolve according to the driver’s daily habits, and will give users a better driving mode as a whole. Moreover, Ai ‘an LX has a more powerful driver monitoring DMS system with vehicle owner fatigue monitoring sensors, which can monitor the driver’s driving state in real time, distracting for more than 3 seconds, that is, actively ensuring safety through warning lights and sound reminders, avoiding fatigue and distraction and improving driving safety; It is reported that this ADiGO 3.0 autopilot system can only be installed through the Aion LX 80 version at present, and the optional price is 39,800 yuan.
Is ADiGO 3.0 system complicated to operate?
As the functions of the automatic driving system are becoming more and more abundant, when you want to turn on or off a driving assistance system alone, you often have to turn it upside down in the menu, and these relatively low-level settings are generally areas that speech recognition can’t control. Take Ai ‘an LX as an example. Although the UI design concentrates the auxiliary systems together, it is necessary to turn on all the horizontal, vertical, blind areas and intelligent parking assistance systems in order to realize all the functions of ADiGO 3.0 system.
At the same time, when driving, the ADiGO 3.0 system is turned on, which is divided into two steps and three buttons in total. Only when the right button is used to turn on the adaptive cruise and set the good distance can the lane keeping function be activated through the left steering wheel pattern button, and the cancellation function can be directly pressed by the adaptive cruise button. On the whole, this combination also invisibly increases the learning cost of drivers.
How is the ADiGO 3.0 system measured?
Through the test drive in the past few days, we have a preliminary understanding of the overall use of ADiGO 3.0 auxiliary driving system carried by this Guangzhou Automobile New Energy Aian LX. However, due to the abnormal working state of the expressway auxiliary system of our Aian LX test drive, the high-precision map cannot be activated normally. Until the test drive is returned, the problem has not been solved, so we can only experience some functions of ADiGO 3.0, and the subjective feelings below are only evaluated based on the current car condition.
Although only part of the functions of the system are used, the sensitivity of the system is extremely high, and the automatic driving and car following functions can be easily realized by turning on the automatic driving system during normal driving.
However, the whole road section referred to in this autopilot system is not all roads. Due to the complex road conditions in China, the current high-precision map only covers 28 urban expressways and urban expressways. Therefore, for safety reasons, when the high-precision map is not activated, we use the adaptive cruise of Ai’ an LX and turn on the autopilot function. When the speed exceeds 80km/h, the car’s automatic lane change can be activated, and its automatic lane change can be completed only by the turn signal. However, Automatic lane change at this speed and above can’t be completely realized. Therefore, in order to get rid of the shackles of hands and feet, it is still necessary to use both hands and feet on high-speed and relatively simple urban expressways, while in urban roads.
Then we talk about lane identification. First of all, when I am driving on a normal paved road, Ian LX will stay in the middle of the lane, and there will be no left/right deviation, and it will stay firmly in the middle of the lane. Relative to the road, this function basically belongs to the state of stopping, and it will automatically tend to drive in the middle from time to time, so this function still requires the use of the road.
At the same time, after the front vehicle slows down or accelerates during driving, the braking system will still keep the whole vehicle at a relatively low speed, and it will not speed up until the front vehicle almost leaves the monitoring range. The overall response seems to reflect the slowdown, but in general, it ensures the safety of the overall driving environment. It is worth noting that most of our test drive encounters morning and evening peaks, so it is "blocked" on the loop to a great extent. In this case, automatic car-following is a more practical configuration for us. After simple testing, the car has four adjustable car-following distance gears, among which the setting distance is adjusted to the latest in congested sections, which is not easy to be jammed; However, the response of the system is usually slow, so it is not recommended to adjust to the nearest distance on extremely congested roads or highways. On the contrary, more space should be left for drivers to respond.
Finally, let’s talk about the automatic parking function that is more suitable for the needs of our car in the configuration of Ai ‘an LX. This function is extremely sensitive and has three functions: parallel parking, vertical parking and parallel parking. Relying on 17 radars (1 forward medium-range millimeter wave, 4 short-range lateral millimeter waves and 12 ultrasonic radars), four panoramic cameras realize more accurate parking and parking functions, but the extreme action of this automatic parking function is too large. At the same time, when looking for a parking space, we should be closer to the surrounding vehicles, so that it will be easier to find the parking position. Generally speaking, this function is also a good practical configuration for people like me who are usually lazy.
Conclusion:
This experience of Ai ‘an LX mainly lies in driving assistance. The overall feeling is quite good. L3 autopilot is natural and smooth, and it is not complicated to open. It is easier to open after proficiency and the process is very friendly. The fly in the ointment is that at present, high-precision maps only support high-speed and urban expressways, which can relieve fatigue to a great extent. However, at present, only a few companies in China have qualification measurement, so there is still room for improvement in high-precision maps. The only pity in this experience is that this Aion LX process is limited by the failure to activate the highway auxiliary system, and it is impossible to truly get rid of the foot on the highway; In urban road conditions, ADiGO 3.0 still has some functional details, such as prompt information and the ability to pass the ramp, which need to be improved in future OTA; At the same time, the test drive model is Ai ‘an LX 80. Although it has not been tested in depth in terms of battery life, after comprehensive use, NEDC’s comprehensive working condition battery life is 650km, which also enables users to travel further.
