What does NOA mean? NOA auto-assisted navigation function

NOA means automatic assisted navigation driving or pilot assisted driving, that is, Navigate On Autopilot. After setting the navigation route and entering the available road section of NOA, the driver can start assisted driving. In the process from point A to point B, various functions such as automatic up and down ramps, self-overtaking, self-changing lanes, adaptive cruise, etc. are realized. However, in the final analysis, NOA is still a high-level assisted driving, not a fully automatic driving.

At present, Weilai, Xiaopeng, Zhiji, Tesla, Avita and other brand models already have the navigator assisted driving function, but each company has a slightly different name for it, but in fact it still belongs to NOA.

Different from conventional assisted driving functions such as adaptive cruise and lane centering, the special feature of NOA is mainly in Navigate. If the vehicle wants to enable NOA assisted driving, it must first set the navigation route, and then the vehicle will be in high-precision driving. With the assistance of map and intelligent driving system, automatic navigation driving is realized.

However, as of now, the NOA automatic assisted navigation driving function of most new energy vehicles still cannot be used in all road conditions. The requirements for enabling NOA mainly include: clear and identifiable lane lines, the vehicle is on a high-speed or elevated road section, the navigation route has been set, and the weather conditions are good, etc. Generally speaking, the NOA function of most car companies is still only available in Use it when running at high speed.

NOA auto-assisted navigation function

1. Automatically drive in and out of the highway ramp: After the vehicle turns on NOA, it will realize autonomous up and down the highway ramp according to the navigation route, high-precision map and intelligent assisted driving system, without driver intervention;

2. Automatically assisted lane change: While driving in NOA, the vehicle will select the optimal lane according to the real-time road conditions, and automatically turn on the turn signal to complete the lane change;

3. Automatic assisted overtaking: On the basis of automatic assisted lane change, if the vehicle in front is driving slowly and meets the overtaking conditions, the vehicle will automatically turn on the turn signal and complete the overtaking;

4. Automatic assisted cruise: NOA actually also includes an adaptive cruise function. The vehicle will follow the vehicle within the allowable range of the vehicle speed, and automatically maintain a safe following distance by accelerating and decelerating.

Through the above functions, the vehicle can realize high-level assisted driving from point A to point B after turning on NOA automatic assisted navigation driving. However, at this stage, most car companies need to charge for NOA, and basically It can only be used on highways, and currently only a few car companies support NOA in urban areas.
