Abstract

An opening and closing body control device for a vehicle includes a drive control portion operating a drive control of an opening and closing body by controlling an operation of a drive device, an information communication portion acquiring control information being used for the drive control by a network communication, and a communication state determination portion determining whether the network communication is established. The drive control portion operates a retention control of the opening and closing body in order to retain the opening and closing body at a moved position in a case where the network communication is not established.

Claims

1. An opening and closing body control device for a vehicle, comprising:

a drive control portion operating a drive control of an opening and closing body by controlling an operation of a drive device;

an information communication portion acquiring control information being used for the drive control by a network communication; and

a communication state determination portion determining whether the network communication is established;

wherein the drive control portion operates a retention control of the opening and closing body in order to retain the opening and closing body at a moved position in a case where the network communication is not established, and

wherein the drive device includes a clutch connecting and disconnecting a transmission of a drive force relative to the opening and closing body while driving the opening and closing body by a motor that serves as a drive source; and

the drive control portion operates the retention control of the opening and closing body by applying a load on the opening and closing body to inhibit the opening and closing body from moving by engaging the clutch.

2. The opening and closing body control device for the vehicle according to claim 1, wherein the drive control portion does not operate the retention control of the opening and closing body in a case where the opening and closing body is unmovably retained by a lock device.

3. The opening and closing body control device for the vehicle according to claim 1, wherein the drive control portion operates a speed reduction control reducing a movement speed of the opening and closing body in a case where the network communication is not established for equal to or longer than a predetermined time.

4. The opening and closing body control device for the vehicle according to claim 1, wherein the drive control portion operates a speed reduction control reducing a movement speed of the opening and closing body in a case where the network communication is not established for equal to or longer than a predetermined time.

5. The opening and closing body control device for the vehicle according to claim 4, wherein

the drive control portion engages the clutch intermittently;

and

the drive control portion disengages the clutch to operate the speed reduction control in a case where the movement speed of the opening and closing body is less than a predetermined speed.

6. The opening and closing body control device for the vehicle according to claim 1, further comprising:

a standby operation request retention portion retaining an operation request as a standby operation request, the operation request being inputted be performed by the drive control portion after the network communication is established; and

a standby operation request update portion updating the standby operation request in a case where a new operation request is inputted before the network communication is established.
