Problems solved by technology

Therefore, when the drive motor is stopped to stop the movement of the glass window when the glass window contacts the opposing member (glass running channel), a gap may be generated due to the inclination of the door depending on the vehicle during the ascent.

Embodiment Construction

[0036] The following will refer to Figure 1 to Figure 5 Exemplary embodiments of the present disclosure will be described.

[0037] Such as figure 1 As shown, the opening-closing control device S (electric window device) of this embodiment includes a motor assembly part MA, a controller C incorporated or connected to the motor assembly part MA, a drive motor 20, a position detector 30, a load detector 40 , and a microcomputer 50 (which controls the operation of the driving motor 20 and performs processing of various signals and various calculations), and a driving circuit 60 . The drive motor 20 can be used as an example of a part of a drive device that opens or closes a glass window 11 provided in a door 10 of the vehicle. The microcomputer 50 can be used as an example of a load change detection section and an example of a stop command section. The driving circuit 60 can be used as an example of a driving force stop device that stops the supply of driving force to the dr...

Abstract

An opening-closing control device that drives an opening-closing member using a driving device and controls the opening-closing member to open or close an opening portion. The opening-closing control device includes a load detector (40) and a driving force stopping device (60). The load detector (40) detects an increase in the load on the opening-closing member due to the pressing of the opening-closing member against the elastic member provided at one end of the opening and which is Directionally opposite to the opening-closing member. When the increased load is greater than a predetermined threshold, the driving force stopping device (60) stops the driving force supplied to the driving device just before the opening-closing member reaches a mechanical limit position in the closing direction of the opening-closing member.

Description

technical field [0001] The present disclosure relates to an opening-closing control device and an opening-closing control method capable of preventing uncomfortable impact noise by reducing excessive impact force in a closing operation of an opening-closing member. Background technique [0002] Conventionally, an opening-closing control device, such as a lifter device for a vehicle window, only applies a driving voltage to a motor to raise or lower the window. Therefore, when the glass window 101 of the door 100 is as Figure 6A and 6B When fully closed as shown in , one end of the glass window 101 squeezes the glass running channel 102 . The glazing 101 is driven until it is mechanically locked. Therefore, an excessive impact force is applied to the glass window 101, the window frame 104 and the driving system (not shown). As a result, the load on the drive system may increase, and uncomfortable crash noise may occur. [0003] In order to solve the above problems, a tec...
