Self-driving technology of automobile includes 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). All above 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, self-driving car is equal to remote control car or intelligent car of Google data center. Self-driving technology of automobile is one of the technical applications of Internet of thing.
If automatic driving above 4-stage is realized, the internal space including seat of car will become important. On the stage of Mind-off, driver can carry out activities like document editing, video conference and appreciating movies when the car in running, therefore the space utilization is greatly improved. The main vehicle enterprises and global seat companies has put forward some suggestions on the next generation of seats and interior decoration concepts for self-driving car 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 automatic seat are similar to common electrical seat, and the difference between them is a set of electronic control system. Electronic control system consists of two control devices, one is active, including electric seat switch, lumbar pad switch, lumbar pad motor and a set of position adjustment motor for seat , adjusting through corresponding seat switch and lumbar pad switch. This control device is the same as common electrical seat completely. The other one is automatic, including a set of position sensor, storage and reset switch and a set of position adjustment motor for 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.
