The self-driving technology of automobiles includes a video camera, radar sensor, and laser rangefinder, which are used to know the surrounding traffic conditions and navigate the road by a detailed map(a map collected by someone). They are achieved by the means of Google’s data center that can deal with the large amount of information collected by the car. In other words, the self-driving car is equal to a remote control car or intelligent car of Google data center. The self-driving technology of automobiles is one of the technical applications of the Internet of Things.
If automatic driving above 4-stage is realized, the internal space including the seat of the car will become important. On the stage of Mind-off, the driver can carry out activities like document editing, video conference, and appreciating movies when the car is running, therefore the space utilization is greatly improved. The main vehicle enterprises and global seat companies have put forward some suggestions on the next generation of seats and interior decoration concepts for self-driving cars in stage-4. The suggestions are proposed around next-generation seats that can be adjusted according to different conditions like rest, sleeping, and driving.
The fundamental structure and type of drive of the automatic seats are similar to the common electrical seats, and the difference between them is a set of electronic control systems. The electronic control system consists of two control devices, one is active, including electric seat switch, a lumbar pad switch, a lumbar pad motor, and a set of position adjustment motor for the seat , adjusting through corresponding seat switch, and lumbar pad switch. This control device is the same as the common electrical seat completely. The other one is automatic, including a set of position sensors, storage and reset switch, and a set of position adjustment motor for the seat that is shared by ECU and manual system. Gear motor for automatic seat adjustment is a micro reduction motor. ZHAOWEI, a manufacturing enterprise that manufactures precision transmission systems, is committed to R&D, designs, and manufactures gear motor for automatic seat adjustment.
