What is the difference between a car s driver assistance features and autonomous driving?

Autonomous driving encompasses assisted driving, ever"Autonomous driving"It seems that it has become synonymous with Tesla overnight. Tesla's exaggerated propaganda misleads consumers, indirectly causing consumers to not realize their monitoring responsibilities while driving, taking it lightly and even falling asleep, and many tragedies have occurred. Driving a car with only Level 2 driver assistance system, sleeping is equivalent to suicide!

Although Tesla's official website has already been"Autonomous driving"Changed to"Autopilot", but I personally believe that it is necessary to let the public understand the difference between assisted driving and autonomous driving.

Remember: Level 2 and below is called assisted driving!

It wasn't until Level 3 that it began to be called "autonomous driving", allowing drivers to avoid constant monitoring. But it is also a specific traffic situation that allows the driver not to control and monitor the car, and once a change in the environment is detected, it is possible to return to the driver's driving mode.

A brief introduction to the main functions of assisted driving

Autonomous Emergency Braking (AEB).

As the most basic active safety function, it will alert when it detects a vehicle, pedestrian or obstacle within a certain distance ahead. When it is less than a safe distance, even if the driver does not have time to apply the brakes, the system automatically brakes to reduce injury.

Adaptive Cruise Control (ACC).

The ACC basic version is based on the automatic cruise function, and monitors the vehicle in front through sensors such as cameras or millimeter-wave radar to keep pace with the vehicle in front. The more advanced version of the ACC can also be used in traffic jams, following the preceding vehicle to stop or start.

Lane Keep Assist System (LKAS).

The system can identify the driving lane, and try to keep the car in the lane by controlling the steering wheel.

Lane Change Assist (LCA).

The first three functions belong to the standard functions of the assisted driving system, and now there are many car companies such as Mercedes-Benz and Nissan have begun to provide passive or active lane change assistance functions, and the driver puts forward the requirements for steering and changing lines to the system by turning the turn signal, and the system controls the steering wheel and speed according to the surrounding traffic flow to implement lane changes. Due to the high requirements for the detection accuracy of surrounding vehicles, cameras and millimeter-wave radars are generally equipped at the front and rear to achieve accurate vehicle information.

MiscellaneousIn addition to the above-mentioned mainstream driver assistance functions, there are also automatic parking, blind spot display, lane departure warning, front vehicle collision warning, traffic sign recognition, driver fatigue detection, high and low beam assist functions, and so on.

Because I paid the intention money in December last year, and now it has been delivered. As the owner of the Xpeng P7, I think the overall driving feeling of the Xpeng P7 is very comfortable, and I think that soon Xpeng Motors will be very popular in the market. Xpeng Motors has a very good quality control, and has achieved excellent results from battery safety to body structure safety.

So I've been driving for a while and haven't found any problems, so I can be absolutely assured of the quality. The city commute is very crisp because of the abundant power on call, which I like very much. Its intelligence is really fragrant, Xiaopeng's Xpilot, for example, in the middle of the highway, the vehicle automatically centers to drive, which greatly reduces the fatigue of driving.

Imagine a congested loop of one to more than ten kilometers, you only need to hold the steering wheel throughout the whole process, that is an easy ah, plus voice control, put **, open and close the window air conditioner, etc., only need to say, which makes me very satisfied, and it is really cool to drive.

Last year, I had a test drive of Xiaopeng P7, after the test drive, I feel that its intelligence is definitely not in vain, giving people a high degree of convenience. A few days ago, because the test drive experience was so good, I was ready to buy Tesla, but then I occasionally heard about Xiaopeng P7 from a friend, and then I went to learn about it, and I thought it was very good, so I decided. After the test drive, I felt that it was very good, gave me a lot of driving convenience, and the intelligence was amazing.

Imagine after work on a tiring day, driving Xiaopeng P7, if you want to listen to the song, you only need to say, turn on automatic assisted driving on congested roads, you only need to hold the side plate, you don't have to spend so much energy to drive, this gives you a relaxed body and mind, what a great experience, quality control is not to worry, overall, it is very good, I have started, just waiting to pick up the car.

The assisted driving of the car means that people also need a certain amount of operation. Autonomous driving, on the other hand, does not require people at all.

Autonomous driving encompasses all the functions of assisted driving, but it can also allow the driver to free up traffic and control the vehicle to do other things.

Assisted driving refers to the assistance provided by the machine, such as reminding you to turn on the lights to change lanes, pay attention to pedestrians, and the main body of driving decisions and execution is still the human driver.

Autonomous driving, on the other hand, refers to a vehicle that can automatically sense its surroundings and navigate itself without human intervention.

The key to judging the difference between assisted driving and autonomous driving is "no human intervention", that is, the machine system will automatically perceive the surrounding environment, automatically analyze and judge the decision, which way to go, accelerate or decelerate, turn or go straight, and automatically control the vehicle to execute the decision.

The driver assistance function does not reach the level of automatic driving, but only assists you in driving.

To be precise, assisted driving needs to be operated by humans, and autonomous driving relies on technology.

Both of them use a variety of sensors installed on the vehicle to collect data, and combine it with map data for systematic calculation, so as to realize the planning of driving routes and control the vehicle to reach the predetermined goal.

However, there is an essential difference between the two: assisted driving is driven by the driver, and autonomous driving technology plays an auxiliary role; Autonomous driving, to be precise, is completely dependent on machines to drive cars.

Advanced driver assistance (ADAS) can be regarded as the premise of driverless cars, belongs to the L2 stage, and has been commercialized, and its main functions include adaptive cruise, collision warning, emergency braking, lane departure warning, etc.;

Unmanned driving, including autonomous driving under specific conditions and in all conditions, emphasizes the autonomous driving of the vehicle to achieve a comfortable driving experience or labor cost savings.

With assisted driving, you still have to pay attention to it, and automatically you can get rid of it.

Assisted driving is just for the convenience of driving, and it is still people who drive, and automatic driving is to set a good route and the car will go by itself.

In the case of assisted driving functions, it should still need to be controlled by a human, and in the case of autonomous driving, it should be much easier for people.

Assisted driving is only to make driving more convenient, and autonomous driving is to completely let the computer control the driving.

Assisted driving is still manned and computer-assisted, while autonomous driving is completely driven by the car itself.

A driver assistance vehicle is a vehicle that assists the driver in driving, accelerating, decelerating, and other activities, and the default system in which the driver is able to complete the remaining dynamic driving activities. In other words, in assisted driving, the driver is still the main controller of behavior. Assisted driving can make driving more comfortable, but it can't replace you.

<> autonomous driving refers to the system that controls the vehicle both longitudinally and laterally, allowing the driver to take some or even complete step off the wheel. Some say that autonomous driving means that the car can drive itself partially or completely on its own, but humans must act effectively when necessary.

Assisted driving does not mean autonomous driving. The driver still has to supervise the vehicle at all times, first of all, we need to be clear that assisted driving and autonomous driving are two completely different things: assisted driving is to reduce driving fatigue and cannot replace all the actions of the driver.

In short, the drive power can also be an auxiliary drive configuration.

Autonomous driving can anticipate all the actions of the driver, including steering, emergency actions, etc. Theoretically, autonomous driving can be done without the intervention of the driver at all, or even the cockpit. Autonomous driving is a computer with the ability to think for itself and is used to steer a vehicle.

However, there may be a misconception among the average consumer that driver assistance is indistinguishable from autonomous driving. While they seem to have the ability to drive autonomously, there are big differences between them. They can also be divided into two different systems.

Basically, the core of driver assistance systems is environmental awareness, which then relies on fixed decision-making procedures and finally execution. Autonomous driving is artificial intelligence, and the operating systems of the two are very different.

Autopilot assists autopilot.

Tesla is the most aggressive of the car companies pushing for self-driving. Tesla's autopilot function, directly translated into Chinese, is "autopilot" or "autopilot". It's easy for the name to give the wrong suggestion and make consumers think of fully automated driving.

Tesla's additional FSD (Fully Self-Driving Car) feature is directly translated as "Full Self-Driving". The name is not implicit, but explicit. However, this "full self-driving" still has to be performed by the driver.

Assisted driving and autonomous driving are just two words apart, but the difference is not small:

1. The main driver of assisted driving is still a person, and the main body of automatic driving is a car. Of course, assisted driving can achieve autonomous driving in some specific scenarios; Autonomous driving, on the other hand, is autonomous driving in most scenarios, and the driver only needs to intervene occasionally.

2. The degree of intelligence of assisted driving and automatic driving is different. Obviously, autonomous driving is more intelligent.

At present, there are no fully autonomous vehicles, but models such as Jidu ROBO-01 have autonomous driving capabilities to a certain extent, which is what we call high-level autonomous driving.

Lane Keeping Assist provides support for lane keeping while driving. With the help of a camera, the marking lines of the driving lane are recognized.

If the vehicle approaches the recognized markings and is likely to depart from the driving lane, the driver is alerted by the vibrations of the steering wheel.

If Lane Keeping Assist recognizes marker lines on both sides of the lane, the system is on standby. This is indicated by a green indicator in the instrument cluster.

Key Benefits:Crime rate decreases. Artificial intelligence will also be used in police cars in the future.

At that point, criminals will not be able to get out of the chase with driverless cars. For example, if the offender is also driving a self-driving car, then the car can be parked remotely by the police, or the car can be blocked by a door or window and sent directly to the police station.

Sure, they might also drive a regular car, but the AI computing power of self-driving cars and the ability to actually locate maps and road conditions can help police catch criminals faster. What's more, it will be almost impossible to find such a vehicle in the future.

Driving assistance includes many functions, among which the more representative ones are adaptive cruise control (ACC), which is used to follow the car at a fixed speed; Another example is lane keeping, which keeps the vehicle in its lane. The combination of the two is the latest traffic jam driver assistance system, which can control the direction and stop of the vehicle in a traffic jam environment.

In addition to performing all the basic functions of driver assistance, autonomous driving can also allow the driver to free up his or her attention from the traffic situation and control the vehicle to do other things. However, the driver still needs to sit in the car and control the vehicle while the autonomous driving system is not yet activated or exited. Unmanned driving, on the other hand, can be completely autonomous without a driver.

Sogou asked. The current level of autonomous driving.

It can be clearly seen from the ** that several key functions that distinguish the level of autonomous driving include: acceleration, deceleration and steering, monitoring the driving environment, feedback to the dynamic driving environment, and system driving mode. Autonomous driving can be divided into six levels.

Level 0: The reason why it is said to be level 0 is that it must not have any accessibility features. These key functions are all performed manually, without any intervention from the car's own systems.

Level 1: Driver assistance. The system is partially involved in acceleration, deceleration and steering, and may intervene partially (e.g. brake assist) based on the driver's driving habits and current driving situation.

Level 2: Partial automation. On the basis of driver assistance, the system can learn the driver's driving habits, plus judge the current driving situation, and autonomously control acceleration, deceleration and steering.

Level 3: Conditional autonomous driving. On the basis of partial automation, the system can monitor the surrounding road environment and analyze the obtained data to calculate the current set accelerator or brake force and direction.

But the driver can stop the autopilot system at any time and take over the car at any time.

Sogou asked. Level 4: High level of autonomous driving. On the basis of Level 3, in addition to judging the driving condition of the car, the system can also deal with emergencies well, even if the driver has not yet reacted to make timely interventions, the automatic driving system can also respond in time to ensure the safety of the vehicle and the people on board.

Level 5: Fully autonomous driving. Autonomous driving in a variety of environments, and the driving style can be customized by the driver, is it aggressive or soft?

So let's take a look at Tesla, which is currently the hottest in the industry, is it autonomous driving?

Tesla's current "self-driving" is not self-driving!

First of all, it can be determined that Tesla's so-called self-driving system should be more accurately called "driving assistance system". Judging from Tesla's official information, Tesla's system integrates several major functions.

Automatic lane keeping.

Sogou asked. Automatic lane keeping is a driver assistance feature that helps the vehicle stay in its driving lane, combined with intelligent safety tracking with 'adaptive cruise control'.
