AutoBeta(AutoBeta.net)05/29 Report--

Electronic rearview mirrors have been promoted in concept cars of major manufacturers for many years, but they have not been applied to actual mass production vehicles, but this barrier is about to be broken by Japanese manufacturers. Toyota earlier announced that the Lexus ES, which went on sale in Japan in October, would provide electronic rearview mirrors. Toyota also said it was the world's first mass-produced model with electronic rearview mirrors.

Honda may not be able to sit still under Toyota's lead. Honda has officially announced that it will replace traditional rearview mirrors with electronic rearview mirrors on the upcoming Honda e-car, becoming a standard feature in the car.

It can be seen that the traditional exterior rearview mirror has been replaced by two prominent electronic cameras, which project an image of the rear side of the vehicle onto two six-inch screens on both sides of the dashboard.

At first glance, it will feel a little strange in the visual effect, but from the manufacturer's point of view, this can make the overall shape of the car look smoother, and more importantly, it can reduce wind resistance and reduce wind noise. Honda said the camera system would reduce air resistance by about 90% compared with traditional rearview mirrors, while the air resistance of the vehicle would be improved by 3.8%. This is of great significance for a miniature electric vehicle. After all, the battery capacity of the car body is limited, and the battery life of each 1km promotion is very important for the vehicle.

Honda also said that the performance of the camera in rainy and foggy weather was uncertain before, but the problem has been resolved. The vehicle reduces Rain Water's impact on the lens by optimizing the overall structure of the electronic camera shell, and the lens is also coated with a hydrophobic coating, so Rain Water will be sucked away no matter where it falls.

The extensibility of electronic rearview mirror is wider! Drivers can choose different functional modes for the in-car screen: one is a traditional perspective, and the other is a wider and wider perspective. When backing up, guides appear on each side view screen to help drivers get around the obstacles.

Honda has also become the brand that has listed this configuration as a standard for a certain model.

The Honda e, an all-electric minicar that focuses on short-distance commutes to the city, officials say it can provide 124miles (200km) of mileage at full power and can charge 80 per cent in 30 minutes in fast charge mode. It was officially listed in Europe at the end of this year, but it is not known whether it will be introduced into China.

It has to be mentioned that this function is faced with the problem of compliance and legality in many countries and regions, and at present, no domestic manufacturer has chosen to do so. It is expected that electronic rearview mirrors will be widely used in most electric vehicles next year, which will be a highlight of publicity, and consumers will then experience whether this new technology really works.
