When you are driving, what are the last roads you want to drive manually? What I don't like the least is the long highway, not only boring and easy to sleepy, but also often because of the wrong on-ramp, I can't move to drive more than 100 kilometers in regret.
So the highway pilot assist function is my favorite, but also I just need to configure when buying a car, if you are the same as me, then the following [high-speed pilot assist function] may be able to help you!
What is High Speed Navigator Assist?
Regarding the high-speed pilot assistance function, the abbreviations given by each family are different, some are called Pilot, some are called Assistant, but it is actually an auxiliary driving function and cannot replace human driving.
We can understand that the pilot assistance function is that after entering the limited road section, the system can prompt the driver to enable, and the vehicle can automatically select the correct route along the navigation in the enabled state, and the middle will reasonably avoid, overtake, change lanes and other actions according to the traffic environment.
Because the highway scene is relatively simple, the pilot assistance driving function at this stage is realized on the highway, and when the vehicle of the function enters the highway, elevated road and urban expressway covered by the high-precision map, the Pilot function can be activated.
After the system is activated, the vehicle can change lanes autonomously, go up and down ramps autonomously based on navigation routes, and trigger automatic lane changes when encountering slow cars on the road to ensure that its vehicles are on the optimal road.
Although all the throttles, brakes, and steering wheels are automatically controlled by the machine during the entire system activation process, the driver cannot be idle, and must keep his eyes on the six roads, listen to the eight directions, and keep his attention on the line at all times.
Because the current stage of artificial intelligence can not solve all the scenes encountered on the road, especially the construction pile barrels on the road, construction railings, and the parallel road during congestion, they are outside the scope of the system's capabilities, and someone must take over the control in advance.
AutoLab organized a winter review of assisted driving last year, most of the models in the driving table departed from Shanghai to Shenzhen, the whole journey was about 1800km, all the Pilot functions have encountered scenes that cannot be solved, especially the sudden Cut in the big truck, if not taken over in time, basically have to pick up the whole village to eat.
Since it still needs people to drive, and there are operational risks, is the high-speed pilot auxiliary function reliable? Is it necessary to buy it?
Believe me, if you standardize the use of high-speed pilot auxiliary function, this function must be reliable, and very fragrant, many car owners have said that they can't go back when they use it, and they no longer want to open the high-speed with their bare hands.
How to standardize the use of Pilot function?
If you think the high-speed pilot assist function is very chicken, it is most likely not used, or have not carefully studied it before.
According to the specifications given by the car company, it is the basis to keep both hands on the steering wheel and keep your eyes on the road ahead during use, because this provides the basis for being able to take over the vehicle at any time.
But that doesn't mean your nerves are going to be highly tense. People instinctively avoid danger, so keep their regular eyes ahead, as long as they don't fall asleep, they can detect danger in advance and take over in advance.
This is equivalent to the high-speed pilot assist enabled when your brain is in a "low energy" state, the thinking link will be much shorter, do not have to do vehicle control in the conventional environment, do not have to consider the route and change ramp.
Full manual driving, cruise control, adaptive cruise + lane keeping, high-speed pilot auxiliary functions, these four can be compared to the application questions, multiple choice questions, fill-in-the-blank questions, and judgment questions you do in the exam.
Although you need to use your brain to think about the problem and write the answer, the "energy consumption" of the brain is completely different. I believe that even if you are a bully, you are more willing to do judgment questions.
Different "energy consumption" corresponds to the difference between the error rate and the "endurance", the easier the brain is during the driving process, the lower the probability of mistakes when encountering important choices, and the safer it is to drive at high speed.
And because most of the brain state is relaxed, so the brain "endurance" is also longer, not only in the driving process can alleviate fatigue, a breath can drive farther, and to the destination, but also more spirit to continue to play.
In my case, if I drive it purely by hand, the limit of the ramp is from Shanghai to Qiandao Lake, about 400km, and when I reach the destination, I don't even want to eat fish heads, I just want to sleep. If you use high-speed navigation assistance for the same journey, you can still dry two large bowls when you reach the destination.
What's the difference between the high-speed Pilot experience?
Although the table lists 9 models, in fact, everyone's experience is completely different, the most special of which is the Super Cruise of cadillac CT6, although it is also a pilot assist function based on high-precision maps, but it cannot achieve autonomous ramping.
In addition to the differences in the definition of functions, the most affecting user experience of the high-speed pilot assistance function is the coverage, optimization for different road conditions, and visual interaction.
The coverage of the system is currently determined by the HD map, and the problem of RTK loss of tunnels and urban canyons has been solved by most car companies at this stage, and the roads covered by the HD map can be enabled.
AutoNavi and Baidu are the main suppliers, and in terms of coverage, both of them have basically achieved full coverage of elevated roads and expressways in core cities such as national highways, north, Shanghai, Guangzhou, and Shenzhen.
Optimizing for different roads can improve the user experience, but this piece is a slow work, and the cost and time period are very high. At present, Xiaopeng NGP and Weilai NOP have done a good job.
At the same time, in addition to being able to have a good functional experience, visual interaction is also necessary, after all, it is a human-machine co-driving, effective information interaction can make the driver more clear in the process of using the machine intention, psychologically more assured, and take over more timely.
At this stage, there are still relatively few models equipped with high-speed pilot auxiliary functions, but as more and more technology companies begin to provide high-speed pilot auxiliary function solutions for car companies, it is believed that by about 2025, major automobile brands will launch models with high-speed pilot auxiliary functions.
