Abstract

An opening/closing body control device includes a control unit that controls a motor unit to perform opening/closing operations between a fully closed position and a fully open position of an opening/closing body provided in a vehicle door, wherein the control unit performs normal-temperature-time voltage control when an outside air temperature is a normal-temperature-time closing operation, and adjusts a speed of the opening/closing body by reducing a supply voltage to the motor unit in a predetermined section before closing the opening/closing body, and wherein the control unit performs closing operations by setting the supply voltage to the motor unit to a higher voltage than the normal-temperature-time voltage control in the predetermined section before closing the opening/closing body when the outside air temperature is a high temperature and the outside air temperature is off the normal temperature and when the outside air temperature is a low temperature and the outside air temperature is off the normal temperature.

Claims (4)

1. An opening/closing body control device is provided with a control unit which controls a motor unit so that an opening/closing body provided in a vehicle door is opened and closed between a fully closed position and a fully open position, The control unit performs normal temperature voltage control when the outside air temperature is in a normal temperature closing operation, and adjusts the speed of the opening/closing body by reducing the supply voltage to the motor unit in a predetermined section before the opening/closing body closes, The control unit performs a closing operation by setting a supply voltage to be higher than the normal temperature voltage control in a predetermined section before closing the opening/closing body when the outside air temperature is high and the closing operation is off at normal temperature and when the outside air temperature is low and the closing operation is off at normal temperature.
2. The opening/closing body control apparatus according to claim 1, wherein, In order to compensate for a decrease in closing force of the opening/closing body due to a change in slip loss when the outside air temperature is low, the control unit performs a closing operation by setting a supply voltage to be higher than the normal temperature voltage control in a predetermined section before closing the opening/closing body, When the outside air temperature is high, in order to compensate for a decrease in closing force of the opening/closing body due to a change in slip loss and/or heat generation of the motor, the closing operation is performed by setting the supply voltage to the motor unit to a higher voltage than the normal temperature voltage control in a predetermined section before closing the opening/closing body.
3. The opening/closing body control apparatus according to claim 1, wherein, When the outside air temperature is out of the normal temperature, the control unit supplies an external supply voltage to the motor unit without performing the normal temperature voltage control so that the supply voltage to the motor unit is higher than the normal temperature voltage control.
4. The opening/closing body control apparatus according to claim 1, wherein, The predetermined section before closing the opening/closing body is a range in which a glass run is provided in a window frame of the vehicle door.

Description

Opening/closing body control device The present invention is a divisional application of patent application number 202010073732.9, application date 2020, 1 month 22, and named "opening/closing body control device". Technical Field The present invention relates to an opening/closing body control device. Background Conventionally, as an example of an opening/closing body control device provided in a vehicle, there are a power window device, a sliding door device, a sunroof device, and the like (for example, refer to japanese patent application laid-open No. 2016-172996). In such an opening/closing body control device, a device is known which includes a motor unit for moving the opening/closing body, and adjusts the moving speed of the opening/closing body by controlling the voltage supplied to the motor unit. In the opening/closing body control device of patent document 1, for example, voltage control (speed control) is performed in the case other than rainfall or snowfall, and voltage control is not performed in the case of rainfall or snowfall. In the above-described opening/closing body control device, whether to perform or not to perform voltage control is determined based on weather information. However, in an environment where the opening/closing body control device is used, since the influence of the outside air temperature is large, the sliding loss is changed by the influence of the outside air temperature, or the motor portion is likely to generate heat. As a result, the tightening force may be lowered. Disclosure of Invention The purpose of the present invention is to provide an opening/closing body control device that suppresses a decrease in closing force due to outside air temperature. The control unit controls the motor unit so that the opening/closing body provided in the door is opened and closed between a fully closed position and a fully open position, performs normal-temperature voltage control when the outside air temperature is in a normal-temperature closing operation, and adjusts the speed of the opening/closing body by reducing the supply voltage to the motor unit in a predetermined period before closing the opening/closing body, and performs closing operation by setting the supply voltage to the motor unit to a higher voltage than the normal-temperature voltage control in a predetermined period before closing the opening/closing body when the outside air temperature is in a high-temperature and normal-temperature-free closing operation and when the outside air temperature is in a low-temperature and normal-temperature-free closing operation. According to the above aspect, when the outside air temperature is out of the normal temperature, the supply voltage to the motor unit is controlled to be higher than the normal temperature voltage, whereby the lowering of the tightening force at the low temperature or the high temperature can be suppressed. Other features and aspects will become apparent from the following detailed description, the accompanying drawings, and the claims. Drawings Fig. 1 is a schematic configuration diagram of a system including an opening/closing body control device according to an embodiment.
