Understanding and Liberating Experience Volvo XC90 Intelligent Autopilot Assisting Technology

How to deal with pedestrians who suddenly rush into the middle of the road in Lu Yu?

A. honk the horn repeatedly to urge pedestrians to avoid.

B. Drive into the reverse lane in an emergency to speed up avoidance.

C. Accelerate the passage in front of pedestrians

D. Brake and stop in time to let pedestrians go first.

This is an exercise of driving test subject four, and there is no suspense to send sub-questions. No matter from the aspects of traffic regulations, driving ethics, or from the perspective of family happiness of drivers and pedestrians, we all know how to deal with it correctly.

The topic of the exam is very simple, but the reality often surprises you in a cold sweat. When you stop, you can at most greet the families of pedestrians in your heart or roll down the window. But what if your reaction speed is not so fast? Or do pedestrians have a running speed close to Bolt? Even in the critical 0.01 second, if your brain can’t accurately judge which of the two pedals under your feet is the brake pedal to save each other’s fate, what should you do?

Today, we don’t talk about the Luther problem of pedestrians and drivers. Chicken soup that has risen to a moral level is difficult to solve the fundamental problem. Then the next question is, can a safe high-tech car save our driving?

Four stages of autonomous driving

Like unmanned driving? V2X? The Internet of Vehicles of the Internet of Everything? ADAS technology? Maybe 90% of consumers can only understand the first one. . . In fact, these difficult technical terms belong to the field of intelligent automatic driving, and the current intelligent driving is divided into the following four stages. Let’s interpret them in plain language.

The first stage — — Driver assistance: such functions as lane departure warning, frontal collision warning and blind spot information system will give the driver an accurate warning.

The second stage — — Semi-automatic driving: automatic control of danger detection and response, the vehicle can achieve emergency automatic braking, automatic follow-up and other functions.

The third stage — — Highly automatic driving: under the condition of specific road conditions and driver’s monitoring, let the car provide automatic control driving for a long time or a short time.

The fourth stage — — Fully automatic driving: the car can fully realize automatic driving without the intervention of the driver.

At this stage, all the auto-driving technologies that have been introduced are at the level of auto-driving assistance. In this level, the vehicle cannot completely take over the driving function, but the driver is always reminded to concentrate on driving to ensure safety.

Experience the advanced autopilot assistance of Volvo XC90.

So what is the experience of driving a car with advanced autopilot assistance? After a day with Volvo XC90 (hereinafter referred to as Volvo XC90), let me share my own experiences.

If we encounter the problem at the beginning of the article, the correct way is to brake. But if you don’t see pedestrians at all (who would have thought someone was running through a red light); Or at that time, due to the stimulation of unexpected situations, the temporary neural connection in the cerebral cortex was interrupted — That is, we often say that "the brain is blank" and there is no response at all, Volvo XC90 will help you and the other party at this time.

XC90 comes standard with City Safety urban safety system, which will give early warning to the driver when the vehicle detects obstacles on the driving route. If the driver does not take braking measures, the urban safety system will take the initiative to slow down and brake.

In addition to the sudden appearance of pedestrians, Volvo XC90 will respond to cars, bicycles, large animals and other obstacles in time, and even avoid or alleviate the sudden collision with vehicles at the fork in the road when turning. This is the first time that the world’s first technology has been applied to Volvo XC90. Recalling the fear of being dominated by unscrupulous pedestrians, electric bicycles for food delivery, modified electric tricycles for express delivery, and drivers with two knives, I silently praised XC90′ s urban security system.

I’m not tired when I’m stuck in traffic/following a car

Driving in a big city, apart from emergencies, the most troublesome thing is traffic jam. The experience of braking with one foot on the accelerator all day long has even made the majority of drivers practice thicker right legs, and also made manual drivers practice thicker legs.

On the basis of the popular adaptive cruise function, Volvo XC90′ s automatic driver assistance system adds active steering function, which can save your growing right leg. After the automatic driving assistance system is started, the vehicle can realize automatic acceleration, braking and steering functions, so that the driver can drive along the current lane in the traffic flow more comfortably. At the same time, the system can also maintain a more suitable driving speed and distance between vehicles, so that vehicles can maintain a more stable and accurate driving position.

All the driver needs to do is put his hands on the steering wheel and pay attention to the road conditions. The system will take over a series of driving behaviors such as acceleration, deceleration, parking and starting. As long as I adapt to this system and dare not take the initiative to take over the brakes, my body and mind are no longer so nervous during the whole driving process. Personally, I feel more relaxed psychologically than physically.

It’s much easier to drive on the highway.

As a person who drives 1,400 kilometers long-distance expressway to Heilongjiang every year to visit his parents-in-law, I still have some opinions on driving on the expressway. The main feeling is "fatigue, boredom and fear", and the most dangerous situation is that the brain will be "numb". On a straight and scenic highway, even if you are not sleepy, you will lose your vitality because of long-term mechanical sitting and long-term concentration — Even if you turn on the cruise control function.

At the speed of 120km/h, the automatic driving assistance system of Volvo XC90 can drive and turn along the clearly recognizable lane signs on the expressway without the preceding vehicle. All you need to do during the whole process is fasten your seat belt and put your hands on the steering wheel. When you need to turn, you don’t need to hit the direction yourself, and the system will correct the driving trajectory with the road. But for safety, the system still requires you to put your hands on the steering wheel. This kind of experience is a kind of liberation, which goes beyond the degree of liberating the right foot by cruising at a fixed speed, because it is completely spiritual liberation. "Watching the road follow the car" is much easier than "staring at the road and driving".

Saving high-risk lane departure

Another big danger on the highway is lane departure. When you are numb, you simply don’t realize that the vehicle is heading sideways to the next lane or the isolation belt, and the consequences are very terrible. Data show that 50% of fatal traffic accidents in the United States are caused by vehicles deviating from the lane. And I often see the front car "shake" without warning on the domestic expressway.

Volvo XC90 introduces a brand-new Run-off Road Mitigation system, which is the first in the world. When the vehicle speed is between 65-140 km/h, this technology can actively prevent the vehicle from deviating from the road surface.

When the vehicle is about to deviate from the lane, the road departure prevention and protection system helps the driver to keep the vehicle on the road through the active intervention and braking of the steering wheel, which is also commonly known as "saving a hand".

When the vehicle is in danger of deviating from the road, the system will exert force on the steering wheel to help the driver keep driving on a safe route, and if necessary, the system will take the initiative to brake. Of course, the driver has always been in control of the vehicle and can freely control the vehicle according to the situation.

Write it at the end

Going back to our original question, can a high-tech car that is safe enough save our driving?

Through the experience of Volvo XC90 autopilot assistance, my personal feeling is that it enables cars to liberate and understand people from the basic function of supporting people through autopilot assistance. It will have a high degree of artificial intelligence, actively explore and meet people’s needs.

Volvo also insists that human beings should retain the right to drive cars. Compared with the practice of unmanned driving completely taking over the vehicle, autonomous driving can make people enjoy driving pleasure, and improve safety and reliability through manual operation under extreme conditions, thus ensuring the safety of drivers and passengers to the greatest extent.

I’m not very optimistic about when the complete autonomous driving will be realized in China. After all, the road traffic quality of Chinese citizens stays at the level of savagery. However, at present, the automatic driving assistance equipped on the Volvo XC90 has been able to greatly improve the safety of driving and alleviate the fatigue of driving on closed roads. Personally, Volvo XC90 can save my driving and meet my needs.

An egg

It is reported that the Drive Me project launched by Volvo Cars will enter a new stage next year. The fully self-driving car launched belongs to a highly self-driving stage, and the driver can completely hand over the driving work to the self-driving car. This is the first public test of the self-driving technology with a very high level.
