Vehicle window opening device
A vehicle window opening device includes an open-close controller, a drawing determination unit, a restriction unit, and an initial mask zone setting unit. The drawing determination unit determines that a vehicle window has drawn in an object when a characteristic value of a motor is greater than or equal to a determination threshold value. The open-close controller executes anti-drawing control based on the drawing determination. The restriction unit restricts the open-close controller from executing the anti-drawing control when the vehicle window is located in the initial mask zone. The initial mask zone setting unit sets an initial mask zone to a normal value when a position where the vehicle window starts to open is located outside a fully closed region and to a fully closed region value that is greater than the normal value when the position where the vehicle window starts to open is located in the fully closed region.
1. A vehicle window opening device comprising:
an open-close controller configured to control opening and closing of a vehicle window that is driven by a motor;
a drawing determination unit;
a restriction unit; and
an initial mask zone setting unit configured to set a predetermined zone from a position where the vehicle window starts to open as an initial mask zone, wherein
the drawing determination unit is configured to determine that the vehicle window has drawn in an object when a characteristic value of the motor is greater than or equal to a determination threshold value,
the characteristic value of the motor changes in accordance with a change in a load applied to the vehicle window when the vehicle window opens,
the open-close controller is configured to execute anti-drawing control that stops opening the vehicle window or reverses the vehicle window by a predetermined amount based on the drawing determination of the drawing determination unit,
the restriction unit is configured to restrict the open-close controller from executing the anti-drawing control when the vehicle window is located in the initial mask zone even if the characteristic of the motor is greater than or equal to the determination threshold value,
when the position where the vehicle window starts to open is located outside a fully closed region including a fully closed position, the initial mask zone setting unit is configured to set the initial mask zone to a normal value, and
when the position where the vehicle window starts to open is located in the fully closed region, the initial mask zone setting unit is configured to set the initial mask zone to a fully closed region value that is greater than the normal value.
2. The vehicle window opening device according to claim 1 , wherein the fully closed region is set in accordance with a depth of the vehicle window inserted into a weather strip arranged on a window frame.
3. The vehicle window opening device according to claim 1 , wherein the initial mask zone setting unit is configured to set the fully closed region value based on a position of the vehicle window in the hilly closed region.
4. The vehicle window opening device according to claim 1 , wherein the initial mask zone setting unit is configured to set the fully closed region value based on a value of voltage applied to the motor when closing the vehicle window.
5. A vehicle window opening device comprising:
an open-close controller configured to control opening and closing of a vehicle window that is driven by a motor;
a drawing determination unit; and
a determination threshold value setting unit, wherein
the drawing determination unit is configured to determine that the vehicle window has drawn in an object when a characteristic value of the motor is greater than or equal to a determination threshold value,
the characteristic value of the motor changes in accordance with a change in a load applied to the vehicle window when the vehicle window opens,
the open-close controller is configured to execute anti-drawing control that stops opening the vehicle window or reverses the vehicle window by a predetermined amount based on the drawing determination of the drawing determination unit,
when a position where the vehicle window starts to open is located outside a fully closed region including a fully closed position, the determination threshold value setting unit is configured to set the determination threshold value to a normal value, and
when the position where the vehicle window starts to open is located in the fully closed region, the determination threshold value setting unit is configured to set the determination threshold value to a fully closed region value that is greater than the normal value.
