Intelligent driver assistance systems are playing an increasingly important role in vehicles today, as drivers are increasingly overwhelmed by urban traffic and spend too much energy in traffic jams. Urban intelligent driving can solve this problem to a certain extent and reduce driving fatigue.
At present, many brands can already achieve an excellent experience at the high-speed NOA level, but the urban NOA level has always been lacking. This is due to the different traffic complexities of the two, the highway traffic conditions are relatively simple, almost only need to overtake slow cars, avoid obstacles and access ramps, but urban road conditions have to face frequent congestion, sudden jumping pedestrians and electric vehicles, complex markings and road signs, these are still for the driver to be careful, for the driver assistance system is extremely difficult, this is the difficulty of urban NOA.
Urban NOA is also one of the directions of the current involution of many brands, not only new power car brands, but also traditional brands are sparing no effort to develop higher-level intelligent assisted driving systems. Zhiji Auto is one of them, on the occasion of the 2024 New Year, Zhiji Auto has pushed the urban NOA system covering the main urban area of Shanghai, and the official description of this system is "more like people", which is also an important experience pursued by the current urban NOA in addition to accuracy and safety.
IM AD City NOA is softer and silkier
When driving in the city, you will often face a mixed flow of people and vehicles, so it is especially important to avoid pedestrians and move forward steadily. IM AD uses deep learning models to imitate the decision-making and operation methods of excellent human drivers, and the system makes a series of deceleration avoidances in time, flashes left and right to avoid risks, and passes through complex road conditions and intersections smoothly, so that drivers do not feel nervous.
Dealing with congestion is also one of the difficulties of urban NOA, if it is too conservative, it is easy to be plugged by others, and if it is too aggressive, it is easy to affect other vehicles that change lanes normally. IM AD can neither bump hard, nor stupid, etc., at the right time, complete the optimal choice, dynamic lane change to avoid congestion, not only to ensure safety, but also to improve the efficiency and continuity of traffic.
IM AD even takes into account the scenario of avoiding buses, as buses change lanes when entering and exiting the station, which is also one of the complex scenarios. At this time, the driver's vision is easily obscured, and the trajectory of pedestrians and motor vehicles is more random, and the potential risk is higher. When approaching the bus harbor, IM AD City NOA takes the initiative to make a small lateral avoidance in the lane, increasing the safe space and enhancing the user's sense of security.
The above is the accurate and efficient aspect of IM AD, and after doing this, it is necessary to pursue comfort, that is, to drive more like that of a skilled driver. For example, it has a silky smooth experience in scenarios such as horizontal and longitudinal speed control, automatic lane change, and automatic parking, like an old driver bringing you the high-end texture you need, rather than unexpected fright. The acceleration and deceleration movements of intelligent driving are more silky and gentle, thanks to the millisecond-level calculation and response speed of the autonomous driving system, which can obtain a smoother and softer acceleration and deceleration effect than human driving.
Precision and safety remain the number one factor
The silky and smooth side of IM AD has been introduced earlier, which is also the most noteworthy of Zhiji's urban NOA, because it can imitate human driving habits while being accurate and safe, making passengers more comfortable and not nervous. Next, we have to talk about the most fundamental thing as an assisted driving system - safety, which is also the foundation of the assisted driving system.
Unprotected left and right turns in one of the scenarios is a common scene for urban traffic. In the case of a large number of vehicles and non-motorized vehicles driving in the opposite lane, the self-driving game can slowly explore and move forward, wait for the right turning time, ensure safety, and smoothly pass through the intersection, taking into account efficiency and safety.
Zhiji City NOA pursues a three-in-one commute of safety, comfort and efficiency; After meeting the high standard of safety and comfort experience, based on powerful real-time perception and integrated planning capabilities, IM AD City NOA intelligently selects the optimal passable lane at the intersection to provide users with higher traffic efficiency. This system will not blindly change lanes, but judge the movement of the vehicle in front, so as to minimize the situation of blocking the lane when going to that lane on the most unobstructed lane, because it is easy for people to sit in the car to achieve obstruction, and the vehicle's camera and radar are more accurate.
The subsequent commuting mode is even more pleasantly surprised
This year, Zhiji will also bring a surprise to car owners, the commuting mode is planned to be launched within the year, this system is one step closer to the current stage of NOA, more intelligent. This system allows the vehicle to operate at intersections even when it is not in urban NOA mode.
By visually recognizing the traffic lights and stop lines of the driving lane, and automatically braking at a red light, there is no need to worry about running a red light due to distraction. When the red light turns green, the vehicle in the straight lane automatically starts to pass through the intersection; In the left and right turning lanes, the system prompts the driver to take over at the first time, avoiding the urging of the rear car and not delaying the time because the start is too slow. If a green light is encountered at an intersection, the vehicle can autonomously pass through the intersection in the straight lane.
In other words, Zhiji's urban NOA will soon be able to provide passengers with all-round safety guarantees, even if the assisted driving system is not turned on, they can pass through the intersection quickly and safely, even if the driver is occasionally distracted, there is no need to worry. Of course, I would like to remind all drivers that the current stage of the assisted driving system cannot completely replace people, and it is still necessary to perceive the surrounding environment and be ready to take over the vehicle at any time under different road conditions.
In the near future, this system will open up more urban car environments outside of Shanghai.
Summary. After the battery life and charging speed of various brands of electric vehicles, the competition in the assisted driving system is still fierce. As a car**We have also experienced a lot of urban NOA, but except for Tesla and Huawei, which are more satisfactory, there is still a certain gap between the rest of the brands. Zhiji has always made its own achievements in the city NOA, of course, we have to go through the follow-up actual experience to know how this system is. However, the active competition of major brands is also a good thing for consumers, and we will soon be able to experience a good enough driver assistance system on lower-end models.
