In the past, everyone’s focus on pure electric vehicles was always on battery life. However, this year there are more voices discussing driving quality and smart technology. This is a good trend, because when we discuss fuel vehicles, , no one is obsessed with how far it can run; with the development of charging networks and the increase in vehicle cruising range, pure electric vehicles can also go where fuel vehicles can go, and "range anxiety" is no longer an issue that should be discussed.
Instead, the driving quality and smart technology of new energy vehicles, especially the latter, including high-level automatic driving assistance systems, high-definition navigation and 5G Internet of Vehicles applications, should become One of the important aspects of future smart cars. At least in the past two years, the high-level automatic driving assistance systems used by various car companies in new cars have been very mature and reliable, especially in terms of active safety, playing a subtle but important role; just like you DISS a car equipped with ten Are the airbags redundant? But if it is used, the protection is 100%.
This year, I have experienced intelligent driving assistance systems from several manufacturers, and they all gave me a very good experience. They changed the "tasteless" image of the past and reduced the driver's burden in actual driving. This is one of the reasons why Cha Ge is increasingly embracing smart cars.
Recently, Brother Cha came to the GAC Aian 4S store to experience the ADiGO 3.0 driving assistance system installed on the Aion V. In addition to conventional functions such as lane keeping/following and forward collision warning, this system also It also supports full-speed hands-free autonomous driving (open as soon as regulations allow), 6-way remote control parking and other functions. At the same time, the Aion? LX is also equipped with this system.
According to Brother Cha’s experience this morning, GAC Aion’s ADiGO? 3.0 autonomous driving system is actually a system that can meet L3 level autonomous driving. Of course, this must be within the permission of the law. The biggest upgrade between it and the conventional L2 level is the "limited release of hands in the full speed range". When the vehicle is in the speed range of 0-120km/h, the system can accurately predict the road conditions 1 kilometer ahead, make the optimal driving route and let the vehicle drive. .
Of course, in order for the vehicle to realize this function and ensure the safety of drivers and passengers, it cannot do without the support of sensing hardware. Taking the Bosch sensing hardware system equipped with Aion V as an example, the entire vehicle is equipped with 12 ultrasonic sensors and 4 high-definition panoramic cameras can provide the vehicle with all-round real-time road data during driving. At present, the ADiGO automatic driving system has traveled more than 46 million kilometers in total. From this point of view, it is quite stable and will not let users be used as "guinea pigs".
In addition to hardware support, the cooperation of high-precision maps is also important. The former includes providing various road data at the millimeter level, such as lane line positions, speed limits, slope curvature, traffic signs/signals and protection Road information such as road barriers is combined with the system during operation to improve the safety of autonomous driving.
However, the current application of high-precision maps also has certain restrictions. Although ADiGO?3.0 has been delivered in large quantities with Aion?V for a long time, L3 autonomous driving scenarios require the support of high-precision maps. , currently this function covers more than 50 key cities and regions including Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, and Hangzhou. This function is temporarily unavailable in other regions.
In actual experience, the human eye cannot tell the difference between high-precision maps and ordinary maps. The former is more like "seeing" specifically for the sensors in the car, and through background analysis and processing, it forms an AR real scene. The map, through projection on the full LCD instrument panel, real-time 3D images + 2D virtual logos, becomes a reality-enhanced navigation, which is far clearer and more three-dimensional than ordinary navigation.
However, the place where this AR navigation and L3 level driving assistance system can play its greatest role is on highways and urban expressways. When we drove the car out of the 4S store, we were faced with a complicated scene with many cars and a road surface. Automatic driving was still possible even at 30-40km/h. Lane assistance and collision prediction systems also played a role, but at this time the driver needed to take over frequently.
It is worth noting that the prerequisite for L3 implementation is legal permission, and my country has not yet introduced such regulations. However, it should be clear that the level is L3, which is also a driving assistance system and cannot be fully automated. Driving; on a highway covered by high-precision maps, you can let the system take over the direction and accelerator pedal, but you must hold the steering wheel and be ready to intervene at any time, and cannot be a "hands-off manager".
When ADiGO?3.0 was designed, it took into account the driver's "lazy" due to the convenience of the system, and is equipped with fatigue driving detection and steering wheel disengagement warning.
Another important innovation of GAC Aion ADiGO? 3.0 is the six-way "one-button remote parking". Compared with cars on the market that support automatic parking, Aion? equipped with this system? V can automatically park in six directions, including "left, front, right X parking in and out", without being restricted by too many angles and scenes. This is especially practical in underground shopping malls and old cities with narrow parking spaces. .
Aion V’s one-touch parking supports two methods: automatic parking and remote control parking. The former requires the driver to sit in the main driving seat and click on vertical parking/parallel parking or parallel parking. In car and other modes, no manual operation is required during the whole process. The system uses the high-definition probe of the car body to generate a 360° panoramic image and a transparent car bottom on the car side, allowing the driver to observe the surrounding conditions of the marked parking space at a glance. In case of emergencies, the system can Stop at any time.
Cha Ge tested the automatic parking function of Aion V several times at different locations from the parking space. The recognition rate and judgment rate were the same as those of experienced drivers. He basically selected vertical or parallel parking. After entering, the system's instructions for parking and correcting the direction appear to be "sophisticated", which is worthy of praise.
When performing remote parking, the system stipulates that the operator and the mobile phone must be within a range of 2-8 meters outside the vehicle. By binding the vehicle's mobile phone, the system uses Bluetooth to communicate with the vehicle under the "GAC Aian" APP. It is connected and can control parking in and out, and it also supports vertical angle remote control parking. This function has not yet been achieved by other brands.
Whether you listen to it or do it, the conditions for remote control parking are more complicated than automatic parking, but its advantage is that when you encounter an extremely narrow parking space, after parking the car, you avoid the need for people to The embarrassment of "crawling" into the passenger seat or "getting" out from the crack in the door has been something that Brother Cha has experienced many times.
It is true that the current remote control parking also has its limitations. For example, the mobile phone needs to be connected to the vehicle via Bluetooth. If the Bluetooth signal is interrupted during parking, or in an underground parking lot with a linear area of ??less than 2 meters ( Or affecting Bluetooth transmission), the entire parking process cannot continue. In fact, during the process of remote parking, I did encounter this kind of confusion once. The Bluetooth signal between the mobile phone and the vehicle was interrupted. Fortunately, after reconnection, the vehicle quickly parked in the correct position "on its own". The current operation convenience is not as good as automatic parking, but it is also a good supplement.
In fact, the ADiGO? 3.0 driving assistance system can help drivers in many ways, but Brother Cha thinks that netizens who are interested in this may wish to go to the GAC Aian 4S store near you for a test drive experience. Because even if I take photos and present functions such as remote control parking and AR real-time navigation, what I can see is only the superficial feeling. However, these functions need to be experienced personally to understand which ones can really assist you in driving and which ones are temporarily unavailable.
Cha Ge’s words:
Finally, back to the original question, are high-level driving assistance systems useless for experienced drivers? If Brother Cha answers no, it is estimated that many experienced drivers will talk about their rich driving experience. In the past, without these assistance systems, they could not drive the car well. However, according to the research statistics of a certain car brand, since the introduction of driving assistance systems, After the system is installed, the vehicle after-sales maintenance rate has been on a downward trend; it can be seen that its greatest value is not to "change" but to "assist" new and old drivers, reducing the chance of errors and reducing the driver's driving pressure; from this point of view, a cost-effective Is the mature and stable driving assistance system just for novices? ?
