Step 2: controller receives the pressure F of the pressure sensor monitoring of the back point of applicationpWith the detection of weight sensor
Weight G, and the height h for the position estimation point of application for passing through pressure sensor, while calculating pressure FpApplication time t；
As t ＜ 35 seconds, controller judged to be failure to actuate；
When t >=35 second, controller estimates children's standard heights h according to height h and height ratio0, searched according to table one
Standard weight G0, G/G is calculated afterwards0And h/h0, using parameter control line in Fig. 7, by G/G0And h/h0Connection is in line, this straight line
Abscissa value corresponding with the intersection point of parameter control line is κ0, comfortable angle θ is calculated according to formula：
Wherein
Wherein, θ is that, suitable for the comfortable angle between the backrest and base of children, unit is degree；θ0For between backrest and base
Initial angle, unit for degree；FpTo put on the pressure of backrest, unit is N；A is that the factor is controlled at angle；κ0For the first control coefrficient；
G0For standardized human body's weight, unit is N；h0For calibrated altitude, unit is rice；H is the height of the point of application, and unit is rice；G attaches most importance to
The weight that quantity sensor is monitored, unit is N；
The standard heights of the seat school-age children of table one, the body weight table of comparisons
Step 3: when t >=35 second, controller starts servomotor 160, servomotor 160 drives reclining apparatus 130 to revolve
Turn backrest 110, backrest 110 is adjusted with fixed angular speed to comfortable angle θ, controller closes servomotor 160.
The present invention at least includes following beneficial effect：1st, the data measured according to sensor group, accurate calculate is suitable to children
Backrest angle；2nd, reclining apparatus is controlled using controller, at the uniform velocity, slowly adjustment backrest, to angle is calculated, prevents adjustment excessive
And bother the sleep of children；3rd, prevent in automobile collision accident, recliner can withstand shocks power and occur larger deformation or
Destruction, locking device prevents backrest resilience problem.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With.It can be applied to various suitable the field of the invention completely., can be easily for those skilled in the art
Realize other modification.Therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
