Abstract

The invention relates to a control driving system for multispeed control of an electric seat. The control driving system comprises a horizontal adjusting motor connected with a cushion of the seat, afirst Hall sensor connected with the horizontal adjusting motor, a backrest adjusting motor connected with a backrest of the seat, a second Hall sensor connected with the backrest adjusting motor anda seat multispeed adjusting control module, and the seat multispeed adjusting control module comprises a microprocessing unit and further comprises a switch sampling unit, a current sensor sampling unit, a motor driving circuit, a Hall sensor sampling unit, a power source management unit and a bus unit which are connected with the microprocessing unit. By the control driving system, a vacancy thatelectric seats on existing market are prone to being quick-turning high-speed pure-electric is made up, and the problem that manual and semi-electric schemes are inconvenient in operation, complex instructure, high in cost and insufficient in comfort and safety in the prior art is solved.

Description

technical field [0001] The invention relates to a control drive system for multi-speed adjustment of an electric seat. Background technique [0002] More and more car OEMs are proposing the multi-speed adjustment requirements for car electric seats, such as the Easy Entry (EZE) function of the front and second row seats, and the quick flip (OTF) function of the third row seats wait. At present, the existing solutions for seat EZE function and OTF function mainly include the following types: [0003] 1) Manual level adjustment and quick folding of the manual backrest; [0004] 2) Electric low-speed level adjustment, manual backrest quick turning; [0005] 3) Electric low-speed level adjustment and electric low-speed backrest folding [0006] However, these existing solutions mentioned above have the following disadvantages: [0007] 1) The purely manual solution has disadvantages such as inconvenient operation and large operating force; [0008] 2) The horizontal adjust...
