Abstract: An open-close body driving device includes a motor configured to open and close an open-close body included in a vehicle and a controller controlling a movement speed of the open-close body driven by the motor. The controller is configured to move the open-close body at a normal speed based on a vehicle-side operating signal output by operation of an operating switch installed on the vehicle and at a speed lower than the normal speed based on a remote operating signal output by operation of a mobile device. The controller is configured so that in a shutting region having a predetermined dimension from a fully-closed position toward an open side, closing movement of the open-close body based on the remote operating signal is slower than closing movement of the open-close body based on the vehicle-side operating signal.

Abstract: An opening-closing body driving motor includes a motor body, a drive circuit, and a control circuit. The motor body is provided to automatically open and close an opening-closing body of a vehicle. The drive circuit supplies driving power to the motor body. The control circuit includes a PWM controller. The control circuit is configured to adjust the driving power by PWM control and control an operation mode of the opening-closing body through the motor body such that the operation mode is changeable. The PWM controller is configured to have a control frequency of the PWM control include a frequency in an audible range based on a predetermined trigger so that the motor body vibrates in the audible range, thereby performing a sound producing operation. The predetermined trigger includes information about an opening-closing state of the opening-closing body or information about activation and deactivation of a child lock.
