Directly attacking the pain points of complex road conditions in China, the ideal ONE technology delivery upgrade realizes safe and intelligent driving
Text/Su Jin Ji
Unmanned driving is still in the exploratory stage for our current technology, but intelligent assisted driving and active safety are in the current time node, but for now, we need to gradually improve it before we can break through to the next stage. Therefore, many car manufacturers are now intensively arranging intelligent assisted driving and active safety for their models, but the effect is uneven.
In order to be able to screen out models that are more suitable for domestic road conditions and safer, an AEB test has been launched in China. There are hundreds of models participating in the test, including many luxury brands, as well as independent brands and joint venture brands. In the end, under the elimination of layers of tests, only a few models entered the final group.
However, after the test, the Ideal ONE won the first place with excellent test results, and was also the only model in the final group that had the ability to identify two-wheelers and transverse cars. Because most of the domestic cities, so the road conditions are relatively complex, in addition to the car, many people will choose to walk out, or choose to ride, and then such recognition ability corresponds to the domestic way of travel, but also more practical.
In the past year, the 2021 Ideal ONE delivered the basic ADAS as well as AEB functions in June 2021, but in December of the same year, the Ideal ONE 2021 delivered NOA navigation assisted driving as well as full AEB (Active Safety) functions. This set of complete AEB functions integrates visual perception algorithms, and Ideal Auto is also the first car manufacturer in China to integrate vision into AEB.
What is the difference between a basic AEB and a full AEB
The basic AEB mainly relies on the detection results of millimeter-wave radar, but millimeter-wave radar has a detection range, as long as objects within this range are detected by millimeter-wave radar, it will be fed back to the driver indiscriminately. For example, vehicles parked around are just within the radar detection range, and even if there is no danger, they will be mistaken by radar as dangerous goods.
Then it will give the driver a danger warning, at this time the warning is a false alarm, which can easily affect the normal judgment of the driver. In order to control such false positives, a lot of data had to be filtered out eventually. However, in the process of filtering data, it is difficult to keep the accuracy of the radar at the equilibrium value, so this also leads to the instability of the radar recognition accuracy.
In order to control the radar accuracy at infinity close to 100%, the ideal car chooses to integrate visual perception into AEB, so the complete AEB after the introduction of vision can accurately detect pedestrians and cyclists, when the driver has not yet reacted, the algorithm combined with visual induction will replace the human brain response to make brakes, and give timely warnings.
Why choose the Horizon J3 chip
Ideal Car is the world's third car manufacturer with full-stack self-development capabilities after Tesla and Xiaopeng, and the vast majority of models on the market are equipped with AEB functions from suppliers, although the supplier's technology is relatively mature, but because of the lack of technical interoperability, car companies can not redefine it according to their own wishes.
Therefore, it is also limited to the full-stack self-development of ideal cars for intelligent driving, so at the end of 2020, ideal cars stopped cooperating with Mobileye and turned to the use of Chinese brands - Horizon J3 chips to launch a full-stack self-development of intelligent driving. Therefore, ideal cars have developed noa navigation assisted driving.
What are the advantages of NOA navigation assisted driving?
The function of the basic ADAS belongs to the ordinary L2 level assisted driving, its self-judgment ability is limited, and the application scenarios covered will be very limited, even if the lights change lanes, it also requires human intervention. NoA, on the other hand, has more autonomy, and is even able to react one step ahead of the human brain.
The NOA can enter and exit the ramp according to the route set by the navigation, switch to high speed, and reduce the speed according to the maximum speed limit of different sections of the road, avoiding speeding when the user does not react. It can also identify the surrounding traffic speed and remind the user to enter the fast lane and overtake at the appropriate time. This can help novice drivers to complete high-speed driving, but also avoid drivers because they are not familiar with the road conditions, fatigue, distraction and miss or take the wrong ramp, exit.
summary:
The ideal ONE is to hope that it can provide users with a safe and comfortable intelligent driving experience, so the ideal car has completed the intelligent driving revolution in 2021. The emergence of complete AEB and NOA further improves the safety efficiency and ease of control of users. In fact, self-developed visual AEB is just as easy as it sounds, but it is very challenging to actually practice, which will cost a lot of money, manpower, physics, and even time. The ideal ONE's insistence on self-development now has substantial significance, which is beneficial for both drivers and pedestrians. At the same time, Ideal Car decided to implement AEB and NOA navigation assistance driving as standard, thereby reducing the opportunity cost of users participating in intelligent driving and meeting the user's travel intelligent safety needs.
