With the rapid development of the self-driving technology of automobiles, the suggestions are proposed around next-generation seats that can be adjusted according to different conditions like having a rest, sleeping, and driving. Thus, more and more manufacturers are looking for seat adjustment motor with gearbox especially in this society where more and more people yearn for autonomous 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 an electric seat switch, a lumbar pad switch, a lumbar pad motor, and a seat adjustment motor set. 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 seat adjustment motor set that is shared by ECU and manual system. The car seat adjustment motors here are micromotors with gears for seat motors.
ZHAOWEI, a manufacturing enterprise that manufactures precision transmission systems, is committed to R&D, designs, and manufactures gear motor for automatic seat adjustment.

Why Use Seat Adjustment Motor for Better Automatic Driving Experience?
The self-driving automobile unit includes a video camera, radar sensor, and laser rangefinder, which makes it possible 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 level-4 (or above) is realized for automatic driving, the internal space including the seat of the car will become important. In the mode 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. For different activities, the height of automatic car seat adjustment also matters. That’s why 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 level-4.
