Description

Opening and closing device for opening and closing body Technical Field The present invention relates to an opening/closing device for an opening/closing body. Background There is known a control for assisting a manual operation by driving a motor of an opening/closing body opening/closing device in order to reduce an operation force of a user when the user opens/closes a rear door provided in a vehicle by a manual operation. For example, patent document 1 describes an opening/closing device for an opening/closing body, which is capable of applying an assist force for assisting a manual operation to the opening/closing body in a manner that follows the manual operation of a user by applying an assist voltage for rotating a motor at a rotation speed corresponding to the opening/closing speed of the opening/closing body when the manual operation is performed by the user. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 2020-117883 Disclosure of Invention Problems to be solved by the invention The operating load of the opening/closing body varies depending on the opening/closing position of the opening/closing body, depending on the shape and type of the opening/closing body, the arrangement of the opening/closing body, and the like. As a result, in the opening/closing device for an opening/closing body described in patent document 1, an excessive or insufficient assist force is generated depending on the opening/closing position of the opening/closing body, and the assist force cannot sufficiently cope with the opening/closing position of the opening/closing body, so that the operability of the opening/closing body may be degraded. The invention provides an opening/closing device for an opening/closing body, which can improve the operability of the opening/closing body. Means for solving the problems In order to achieve the above object, an opening/closing device for an opening/closing body of the present invention includes a driving unit having a motor for opening/closing a body provided in a vehicle, a position detecting unit for detecting an opening/closing position of the body, and a control unit for controlling the opening/closing movement of the body by using a detection signal of the position detecting unit, wherein the control unit controls an input value to the motor so as to follow a target input value predetermined according to the opening/closing position of the body when an assist condition for assisting a manual operation of the body is satisfied. Effects of the invention According to the present invention, operability of the opening/closing body can be improved.
