Not for female drivers, see Nissan's security strategy from panoramic camera
Panoramic photography is a new thing that has emerged in recent years. Due to the low cost of hardware, this set of things is still mostly used only by "advanced cars". Nissan is a special case in conventional brand models, and it seems to have a special liking for it, and it has been popularized on many models of around 200,000.

Many people, especially male/old drivers, don't have a cold for panoramic camera. The reason is that this thing is also used when assisting parking. It is a typical "professional device for novice female drivers." To be honest, the author also thought so at first. However, along with the new active safety strategy demonstrated by Nissan's new car in the past two years, the author found that the use of Nissan's panoramic camera is really more than just “parking more convenientâ€.
Nissan Smart Interior Rearview Mirror Technology
The value of panoramic camera in the new active safety technology has been developed so far. Passive safety technology represented by body stiffness, energy dispersion and airbags has been improving, but the room for improvement is not large. More and more manufacturers have begun to focus their research and development on active safety technology, which is called prevention. In this respect, the typical representative of the European system is Volvo, while the typical representative of the Japanese is not a Nissan. Nissan can become a representative of Japanese cars, and it has a lot to do with the "zero accident" goal proposed by it. This is certainly not possible, but the vision is always good.
Today, we are no stranger to some new types of active safety technology, such as lane departure warning, collision warning, adaptive cruise, and parallel assistance. The principles and effects of these technologies are different, but a general idea is consistent, that is, to obtain the information outside the vehicle through the sensing element, and then to calculate and judge through the in-vehicle system, and to provide early warning or intervention when necessary. Prevent accidents such as rear-end collisions, deviations from lanes or parallel crossings. Especially in the driver's distraction, fatigue driving or the presence of driving blind spots, the effect is very obvious, greatly reducing the incidence of accidents.
The sensing components of such technologies are generally ultrasonic transmitters, and the safety strategy of Nissan vehicles is no exception. The difference is that Nissan has added panoramic camera to assist in these strategies. For example, the multi-sensor system of its front-view camera will judge the camera by the perception of the camera when the vehicle is close to the front of the vehicle and when there is a pedestrian in front of the vehicle, and prompt the driver to pay attention to avoid accidents in different ways. . Similarly, the blind spot warning system and the lane departure warning system, Nissan also joined the image analysis technology of the panoramic camera monitoring system. Although the ultimate goal is the same, due to the assistance of panoramic photography, the effect is better, the false positive rate is lower, and the expected effect can be achieved more effectively.
Based on panoramic camera technology to develop low-speed early warning precautions Many people contact panoramic cameras from the "parking", and basically think that it is just a "360 ° upgrade version" of the reversing image. Indeed, the most powerful use of panoramic camera is indeed in low-speed conditions, such as parking, turning, low-speed follow-up, etc., its 360° blind zone vision is indeed very pleasant, but its role is Not limited to this.
For the veteran, no 360° image may still be parked, but for the novice, even if there is a 360° blind spot, it is not necessarily foolproof. Why? Because he/she will not care. One did not pay attention, either scraping the pillars or hitting people. Especially the latter is the most terrible and most needy for the driver. Based on this panoramic camera, Nissan has developed a number of derivative active safety technologies. These technologies are not just a good-looking gimmick, but have a real effect.
For example, the Moving Object Detection Technology (MOD) is specially developed for drivers who may ignore pedestrians, especially children, at low speeds. With it, once there is a moving object on the trajectory of the vehicle, it will not only be displayed on the display screen, but also will promptly issue an early warning based on the information collected by the system. This is like having someone outside to help you stare at the moment, and when you issue a warning like "Beware, someone" when necessary, it can greatly reduce the probability of an accident. Of course, the system's early warning is not limited to moving objects, and the Reverse Collision Prevention System (BCI) will also alert you at critical moments. This feels a bit like the reversing radar, but the principle is different and the coverage is not the same.
Using panoramic cameras to prevent extreme driving errors from occurring in common accidents, there are some ridiculous cases. For example, the car inexplicably drove into the restaurant and drove into the river ditch; not only did the car not slow down after hitting the car, but it also ran rampage until it hit a big obstacle and stopped. The scenes of accidents that these old drivers can't understand are mostly the same – novices, when the tension is tight, the throttle is braked, and all the way to the end. Obviously, the damage caused by this misoperation is very large.
In Nissan's safety strategy, there are systems that specifically target such misoperations, such as "incorrectly stepping on the acceleration suppression system." With the current electronic throttle and active brake technology, it is not difficult to "step on the throttle car not to go". The difficulty is how to judge when the driver is mishandling and when is the normal operation of the driver. Nissan's system, judging by the panoramic camera - through panoramic camera information and specialized image analysis technology, coupled with ultrasonic ranging, the system can understand the obstacles in front and rear of the vehicle. If there is an obstacle, the driver will slam on the gas pedal, and the system will judge it as a misoperation, and take a series of measures - suppress the throttle opening to prevent the acceleration from proceeding, and then issue warnings and alarms to alert the driver. If it doesn't work, the driver doesn't know how to brake, and the system will also implement automatic braking. If this technology can be popularized on all models in the future, it is estimated that the inexplicable scene of the accident will never be seen again.
Summary So far, we can find the strategy of Nissan. The previous emphasis on the panoramic camera and the investment seems to be a bit of a gimmick, because this configuration does look dazzling and does not have much value in the eyes of the old driver. However, these years, through the development of panoramic imaging technology, it can be seen that Nissan has proposed new concepts and new preventive safety measures in the layout of security strategies. Nissan's investment in new active safety is gradually turning into product competitiveness. For example, the new Qijun can be equipped with line assist, lane departure warning and panoramic camera on the 2.5L luxury version with a guide price of 238,800, which is still the only one in the same class. The market performance of Xinqijun after its listing is not related to this. There are also new Loulan, the next generation of hackers, should be the beneficiaries of this strategy. Of course, for the author, I am more concerned about the impact of Nissan's strategy – if it can drive other brands together, this will undoubtedly increase the overall safety of the model and reduce the overall accident probability. It is beneficial.
