When it comes to high-end intelligent driving assistance functions, it is difficult not to associate people with the new forces of car manufacturing, and this is easy to understand, after all, their achievements in this area are far more than those of traditional car companies. However, in order to better cater to consumer car demand and compete for car market share, traditional car companies have also entered the market, and today's protagonist - Buick eCruise Pro intelligent assisted driving technology is a clear example.
As of press time, Buick has carried out OTA remote upgrade push for GL8 Evia and GL8 Luzun related models, and added ILC driver command lane change function. The Buick GL8 became the first model of SAIC-GM to upgrade its driver assistance system through OTA, and also gained higher-level intelligent driver assistance functions.
(The model in the text is the 2022 Avenir Evia six-seater sage version)
As for why we chose to upgrade the GL8 model first, instead of choosing Oncovie, Encore Banner or Regal and LaCrosse family cars. In response to this problem, I also consulted the relevant engineers of the manufacturer at the test drive activity site.
Buick GL8 Aivia intelligent driving assistance hardware configuration is relatively high, its forward camera using MobileEyeQ4 fourth-generation image recognition chip, computing power than the previous generation 10 times, can accurately identify vehicles, pedestrians, two-wheelers, lane lines and other target information; 5 millimeter wave radar on the body can penetrate dust fog, rain and snow, and then with 12 ultrasonic radar, 4 megapixel panoramic cameras, can achieve all-weather all-weather work; at the same time, highly integrated inertial guidance using 5-axis gyroscope design, Accurately calculate the trajectory and attitude of the vehicle. In summary, this model has become the first choice for pre-OTA.
After understanding the original intention and the vehicle's driving assistance hardware, we began to experience. In order to highly restore the actual car scene, we first start with the OTA upgrade.
You can see that the screen shows that the installation time is about 55 minutes, in fact, it only takes about a minute to complete, the speed exceeds expectations, the details are done well, and the system will guide the user how to operate in the form of text and voice improvement during installation. After the upgrade, you can see the new "Driver Command Lane Change" function in the Driving Assistance function menu.
This function is actually very easy to understand, when the system is started and the current environment meets the system work, the driver dials the turn signal lever and the vehicle automatically completes the lane change.
(Note: The experience site is a test section)
Basic parameters of the test vehicle:
Powertrain: 2.0T+9AT
Body size: 5219/1878/1799mm
Wheelbase: 3088mm
The driving experience of the Buick GL8 Evia will not be repeated with you, and directly experience the ILC driver command lane change function. In order to activate this function, it is necessary to first open the LCC lane centering system, which means that the function can be used under the clear road conditions of the lane line, and the speed should be higher than 40km/h, the conditions are not harsh, most urban roads can be satisfied, and the highway is not to be said.
The relevant function operation buttons are located in the center of the left side of the steering wheel, which is extremely convenient and easy to use, and with the huD, the driver does not need to look down at the dashboard, which can improve driving safety.
When the green halo on the outer ring of the LCD instrument and the green steering wheel icon below are lit, it means that the ILC driver command lane change function has been turned on and can work at any time. The turn signal lever system will help you change lanes, and it's important to note that only one lane can be changed at a time. Of course, don't think of this action as simple, because there are many factors involved, including the front and rear vehicles and their own speed, which must be calculated repeatedly.
What happens if the vehicle is already on both sides of the road and hits the turn signal on the outside?
When the driver issues the command, the relevant hardware will scan the side of the preconverted road, when it is found that the first time can not change lanes, the side of the lane line on the instrument will become red, for warning, there will be a window period of 10 seconds, during this period, if the system recognizes that the lane can be changed, it will complete the instruction, if more than the above time the system will give a clue that it cannot change lanes.
In addition, we simulated a relatively common situation in which the system that issued lane change instructions would deal with when there were vehicles around the vehicle at the same speed as itself.
As before, the hardware will first scan the target lane, and find that the vehicle in the target lane is consistent with its own speed for a long time or if it is fast or slow, the system will issue a prompt, and the window period is also 10 seconds, during which if the conditions for changing lanes are met, the system will also wait for the opportunity to complete the instruction. If the time is exceeded, it will prompt "There is a danger in changing lanes The instruction to change lanes is not available".
The actual experience of this function can be summarized as three points, one, the operation is simple and there is no difficulty in getting started; second, the system is relatively cautious, the safety index is high, and it can also eradicate the bad habit of changing lanes without turning the signal; finally, it is applicable to a wide range of scenarios, which can be applied in most urban roads, but the experience under high-speed road conditions will be better. In addition, for the driver assistance hardware configuration of the GL8 Aivia model, the manufacturer staff announced that the driving assistance level of L3 can be supported up to the future.
For the ILC driver command lane change function, the owner of the Buick-related model in front of the screen can upgrade the OTA to experience it, which will not disappoint you.
