Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model provides a seat control device, as shown in figure 1, the device includes: the seat control system comprises a seat controller 1, a palm print recognition module 2, a seat state sensor module 3 and a motor driving module 4 which are connected with the seat controller 1, and a motor module 5 connected with the motor driving module 4; the seat state sensor module 3 is used for outputting a voltage signal reflecting the seat state to the seat controller 1; the palm print recognition module 2 is arranged on the outer ring of the steering wheel, a control instruction is output to the seat controller 1 after the palm print image of the driver is obtained and successfully matched with the stored palm print image, the seat controller 1 outputs a control signal to the motor driving module 4 according to the instruction to enable the motor module 5 to work, and the seat is adjusted to a memory state corresponding to the palm print of the driver; the seat state includes position coordinates of the seat in the front-rear direction, the up-down direction, and the inclination angle of the backrest.

In the embodiment, the device mainly comprises a seat controller 1, a palm print recognition module 2, a seat state sensor module 3, a motor driving module 4 and a motor module 5. The seat controller 1 is respectively connected with the palm print recognition module 2, the seat state sensor module 3 and the motor drive module 4, and the motor drive module 4 is connected with the motor module 5. The palm print recognition module 2 mainly comprises an image collector and a microprocessor. The image collector is arranged on the outer ring of the steering wheel, as shown in fig. 2, and is used for obtaining a palm print image of a driver; and the microprocessor carries out image processing on the palm print image, extracts the palm print image characteristics and respectively matches the palm print image characteristics with the stored plurality of palm print image characteristics. If the matching is successful, outputting a control instruction to the seat controller 1; the seat controller 1 reads corresponding memory state data according to the instruction, and then outputs a control signal to the motor driving module 4 to enable the motor module 5 to work, so that the seat is adjusted to a memory state.
