Abstract

An opening-closing member controller includes a control unit that executes an initialization process to store at least a fully closed position of an opening-closing member. In the initialization process, the control unit closes the opening-closing member, executes entrapment reversing control one or more times when entrapment is detected to open the opening-closing member, and closes the opening-closing member after the entrapment reversing control to store a position where the opening-closing member locks as the fully closed position.

First claim

The invention claimed is:

1. An opening-closing member controller comprising:
a control circuitry that executes an initialization process to store at least a fully closed position of an opening-closing member,
wherein, in the initialization process, the control circuitry closes the opening-closing member, executes entrapment reversing control one or more times when entrapment is detected to open the opening-closing member, and closes the opening-closing member after the entrapment reversing control to store a position where the opening-closing member locks as the fully closed position.

2. The opening-closing member controller according to claim 1 , wherein the control circuitry closes the opening-closing member after the entrapment reversing control in the initialization process.

3. The opening-closing member controller according to claim 1 , wherein
the control circuitry has an entrapment prevention functionality that opens the opening-closing member by a set reversing amount when entrapment is detected, and
the entrapment reversing control in the initialization process uses the entrapment prevention functionality.

4. The opening-closing member controller according to claim 1 , wherein
the control circuitry has an entrapment prevention functionality that opens the opening-closing member by a set reversing amount when entrapment is detected, and
when closing the opening-closing member after the entrapment reversing control in the initialization process, the control circuitry enables the entrapment prevention functionality in a range excluding an entrapment detection disabling range, which is based on an entrapment position where the entrapment reversing control was executed.

5. The opening-closing member controller according to claim 4 , wherein
when entrapment is detected in a range excluding a dead zone that is set in accordance with the stored fully closed position, the entrapment prevention functionality opens the opening-closing member by the set reversing amount, and
the control circuitry stores the entrapment position as a provisional fully closed position and sets the entrapment detection disabling range as the dead zone of the entrapment prevention functionality.

6. The opening-closing member controller according to claim 4 , wherein the control circuitry sets an entrapment detection disabling range dedicated to the initialization process based on the entrapment position.

7. The opening-closing member controller according to claim 1 , wherein, in the initialization process, the control circuitry opens the opening-closing member for a small preset amount during the entrapment reversing control and closes the opening-closing member without performing entrapment detection after the entrapment reversing control.

8. The opening-closing member controller according to claim 1 , wherein the control circuitry executes the entrapment reversing control two or more times in the initialization process.

9. The opening-closing member controller according to claim 1 , wherein, in the initialization process, the control circuitry determines that initialization is incomplete when closing the opening-closing member after the entrapment reversing control if the position where the opening-closing member locks is not within a preset expected lock range.

10. The opening-closing member controller according to claim 9 , wherein the control circuitry outputs an initialization incompletion signal when determining that the initialization is incomplete.

11. The opening-closing member controller according to claim 9 , wherein the control circuitry opens the opening-closing member when determining that the initialization is incomplete.

12. The opening-closing member controller according to claim 9 , wherein the control circuitry executes the initialization process at least one time again from the beginning of the initialization process or during the initialization process when determining that the initialization is incomplete.

13. The opening-closing member controller according to claim 1 , wherein, in the initialization process, the control circuitry determines that initialization is incomplete when opening the opening-closing member in the entrapment reversing control if the opening-closing member reaches a fully open position.

14. The opening-closing member controller according to claim 1 , wherein, in the initialization process, the control circuitry determines that initialization is incomplete under a situation satisfying at least one of a condition in which an operation switch that opens and closes the opening-closing member is operated, a condition in which an initialization suspension signal is input, a condition in which a voltage drop over a preset value or greater occurs, and a condition in which a vehicle door is opened or closed.

15. The opening-closing member controller according to claim 1 , wherein the control circuitry starts the initialization process when an initialization request signal is input and closes the opening-closing member until entrapment is detected to execute the entrapment reverse control.

16. The opening-closing member controller according to claim 1 , wherein the control circuitry starts the initialization process when an initialization request signal is input, opens the opening-closing member and stores the position where the opening-closing member locks as a fully open position, and closes the opening-closing member until entrapment is detected to execute the entrapment reverse control.

17. An initialization method for storing at least a fully closed position of an opening-closing member in an opening-closing member controller, the initialization method comprising:
executing entrapment reversing control one or more times that opens the opening-closing member if entrapment is detected when closing the opening-closing member; and
storing a position where the opening-closing member locks when closing the opening-closing member after the entrapment reversing control as a fully closed position.
