Historical background of research on reversing radar at home and abroad

At first, reversing radar was only the patent of high-end models such as BMW and Mercedes-Benz, but in recent years, some newly-built low-end models have also added reversing radar to their configurations.

First generation: when reversing, honk the horn to remind you.
