Description

Automobile seat adjusting method and electronic equipment

Technical Field

The invention relates to the technical field of automobiles, in particular to an automobile seat adjusting method and electronic equipment.

Background

As shown in fig. 1 to 3, in a conventional vehicle seat, the backrest direction of the seat, the up-down direction of the entire seat, and the front-rear direction of the entire seat can be adjusted.

After adjustment, the occupant may record the adjusted position of the seat for later use. The existing memory method, using the coordinate record as shown in fig. 4, corresponds to the following list:

position of	Front and back	Up and down	Back support
				Initial point of delivery	X	Y	Z
Memory point 1'	X + A1' (displacement)	Y + A2' (displacement)	Z + A3' (displacement)
				Memory point 2'	X + B1' (displacement)	Y + B2' (displacement)	Z + B3' (displacement)

Recording data of the memory point 1': three relative displacement amounts of A1 ', A2 ' and A3 ' relative to the origin;

recording data of the memory point 2': b1 ', B2 ' and B3 ' are relative displacement amounts relative to the origin.

Fig. 5 is a schematic diagram of the random point 3 'back to the memory point 1', and the corresponding list is as follows:

position of	Front and back	Up and down	Back support
				Initial point of delivery	X	Y	Z
Memory point 1'	X + A1' (displacement)	Y + A2' (displacement)	Z + A3' (displacement)
				Random position 3'	X + C1' (displacement)	Y + C2' (displacement)	Z + C3' (displacement)

The amount of displacement from the random point 3 'back to the memory point 1' is:

the seat front-rear movement amount is C1 '-a 1';

the seat up-down movement amount is C2 '-a 2';

the amount of movement of the seat back is C3 '-A3'.

However, the origin of the prior art is a factory origin, which is set at the time of factory shipment. In the processes of production, transportation, disassembly, installation, repair and the like, the original point may be inconsistent with the factory initial point, so that the memory mode fails. For example, memory point 1' is set before repair. Due to the change in origin after rework, for example:

position of	Front and back	Up and down	Back support
				Initial point of delivery	X	Y	Z
Initial point after repair	X1	Y1	Z1
				Memory point 1'	X + A1' (displacement)	Y + A2' (displacement)	Z + A3' (displacement)
Random position 3'	X1+ C1' (displacement)	Y1+ C2' (displacement)	Z1+ C3' (displacement)

Therefore, the amount of displacement from the random point 3 'back to the memory point 1' should be:

the seat front-rear movement amount is X1+ C1 '-X-a 1';

the seat up-down movement amount is Y1+ C2 '-Y-a 2';

the amount of movement of the seat back is Z1+ C3 '-Z-A3'.

In fact, the prior art still adopts the calculation methods of the seat front and rear movement amount C1 '-a 1', the seat up and down movement amount C2 '-a 2' and the seat back movement amount C3 '-A3', so that the seat cannot be restored to the memorized position.
