When hindering object, stop motor operation immediately, to reach intelligent anti-clip effect when seat movement, effective protection passenger and luggage object
Product.
With reference to the accompanying drawing, the major function realized to the present invention is described in detail.
As shown in Figure 3,4, the present invention realizes that the process of seat comfort constant speed regulation function in the horizontal direction is as follows:
When switch sampling unit 12 detects that seat adjusting switch 7 executes the movement of seat cushion Level tune or bus unit
After 17 receive the seat cushion level adjustment commands from vehicle body 8, if instruction seat is forward, microprocessing unit 11 is driven by motor
Dynamic circuit 14 carries out PWM control to Level tune motor M1, and to drive seat, (adjustment speed is, for example, constant motion horizontally forward
20mm/s), until stopping after reaching catch point position；Similarly, if instructing seat backward, microprocessing unit 11 passes through motor driven
Circuit 14 carries out PWM control to Level tune motor M1, and to drive constant motion after seat horizontal direction, (adjustment speed is, for example,
20mm/s), until stopping after reaching catch point position；In the process, if switch sampling unit 12 detects seat adjusting switch 7
Stopping movement or bus unit 17 receive ceasing and desisting order from vehicle body 8, then microprocessing unit 11 passes through motor driven electricity
Road 14 makes Level tune motor M1 stop that seat is driven to move horizontally forward or backward.
As shown in Figure 5,6, the present invention realizes that the process of the comfort constant speed regulation function of seat back angle is as follows:
When switch sampling unit 12 detects that seat adjusting switch 7 executes backrest angle adjusting movement or bus unit
After 17 receive the backrest angle regulating command from vehicle body 8, if instruction backrest travels forward, microprocessing unit 11 passes through electricity
Drive circuit 14 adjusts motor M2 to backrest and carries out PWM control, to drive backrest constant motion (adjustment speed example forward
For example 3.25 °/s), until stopping after reaching catch point position；Similarly, if instructing backrest backward, microprocessing unit 11 passes through electricity
Drive circuit 14 adjusts motor M2 to backrest and carries out PWM control, to drive backrest constant motion (adjustment speed example backward
For example 3.25 °/s), until stopping after reaching catch point position；In the process, if switch sampling unit 12 detects that seat is adjusted
7 stopping of switch movement or bus unit 17 receive ceasing and desisting order from vehicle body 8, then microprocessing unit 11 passes through motor
Driving circuit 14 makes backrest adjusting motor M2 stop that backrest is driven to move forwards or backwards.
As shown in Figure 7,8, the present invention realizes that the process of EZE function is as follows:
When Level tune motor M1 or backrest, which adjust motor M2, to be currently running, first, second Hall sensor H1, H2 points
Not Shi Shijiankong Level tune motor M1 and backrest adjust the operation of motor M2；When Level tune motor M1 or backrest adjust motor
After M2 is out of service, if switch sampling unit 12 detects that seat adjusting switch 7 executes EZE movement or bus unit 17 connects
Receive the EZE order from vehicle body 8, then microprocessing unit 11 save by Hall sensor sampling unit 15 from first, second suddenly
The collected present level of your sensor H1, H2 adjusts motor M1 and backrest adjusts the location information of motor M2, when saving successfully
Afterwards, microprocessing unit 11 extracts the position of the Level tune motor M1 and backrest adjusting motor M2 of preset corresponding EZE function
Information, and motor M1 and backrest adjusting motor M2 are adjusted by 14 controlled level of motor-drive circuit, to drive seat cushion 3 and backrest
5 high-speed motions are to the position EZE (backrest adjustment speed is, for example, 10 °/s, and seat cushion adjustment speed is, for example, 40mm/s)；If switch is adopted
Sample unit 12 detects that seat adjusting switch 7 stops EZE movement or bus unit 17 receives the EZE from vehicle body 8 and restores
Order, then microprocessing unit 11 extracts the Level tune motor M1 saved before carrying out EZE and backrest adjusts motor M2
Location information, and motor M1 and backrest are adjusted by 14 controlled level of motor-drive circuit and adjust motor M2, to drive seat cushion 3
Returning to the position before carrying out EZE with 5 high-speed motion of backrest, (backrest adjustment speed is, for example, 10 °/s, and seat cushion adjustment speed is for example
For 40mm/s).
As shown in Figures 9 and 10, the present invention realizes that the process of OTF function is as follows:
When backrest, which adjusts motor M2, to be currently running, the second Hall sensor H2 monitors the fortune that backrest adjusts motor M2 in real time
Row；After backrest adjusting motor M2 is out of service, if switch sampling unit 12 detects that seat adjusting switch 7 executes OTF movement,
Or bus unit 17 receives the OTF order from vehicle body 8, then microprocessing unit 11 is saved by Hall sensor sampling unit
15 adjust the location information of motor M2, after saving successfully, micro process from the collected current backrest of the second Hall sensor H2
The backrest that unit 11 extracts preset corresponding OTF function adjusts the location information of motor M2, and passes through motor-drive circuit 14
It controls backrest and adjusts motor M2, to drive 5 high-speed motion of backrest to the position OTF (backrest adjustment speed is, for example, 15 °/s)；If opening
It closes sampling unit 12 and detects that seat adjusting switch 7 stops OTF movement or bus unit 17 receives the OTF from vehicle body 8
Restoring order, then microprocessing unit 11 extracts the location information that the backrest saved before carrying out OTF adjusts motor M2, and
Backrest is controlled by motor-drive circuit 14 and adjusts motor M2, to drive 5 high-speed motion of backrest to return to the position before carrying out OTF
(backrest adjustment speed is, for example, 15 °/s).
