Abstract

A vehicle door lock device includes: an actuating lever linked to an electric motor, rotatable in a rotation regulating range, rotating in one direction toward a closing position on one end side of the rotation regulating range, thereby holding, in a complete-closing state, a door having been in a half-closed state, and rotating in the other direction toward a release position on the other end side, thereby releasing the holding of the door in the complete-closing state; a first neutrality detecting switch generating a first neutrality detection signal having logic switched at a first neutral position; and a second neutrality detecting switch generating a second neutrality detection signal having logics switched at a second neutral position and a release start position which are a boundary position of the neutral region on the closing position side, and a boundary position of the neutral region on the release position side, respectively.

First claim

What is claimed is:

1. A vehicle door lock device comprising:
an actuating lever that is linked to an electric motor, is provided to be rotatable in a rotation regulating range, rotates in one direction from a neutral region toward a closing position on one end side of the rotation regulating range, thereby holding, in a complete-closing state, a door having been in a half-closed state, and rotates in an other direction from the neutral region toward a release position on an other end side of the rotation regulating range, thereby releasing the holding of the door in the complete-closing state;
a first neutrality detecting switch that generates a first neutrality detection signal having a level that is switched when the actuating lever reaches a first neutral position in the neutral region; and
a second neutrality detecting switch that generates a second neutrality detection signal having a level that is switched when the actuating lever reaches a second neutral position which is a boundary position of the neutral region on the closing position side, and that is switched when the actuating lever reaches a release start position which is a boundary position of the neutral region on the release position side.

2. The vehicle door lock device according to claim 1 , further comprising:
a control device that controls drive of the electric motor,
wherein, when the electric motor is driven to cause the actuating lever to rotate from the closing position to the neutral region, the control device stops the drive of the electric motor, based on switching of the level of the second neutrality detection signal when the actuating lever reaches the second neutral position, or, when the level of the second neutrality detection signal is not switched, based on switching of the level of the first neutrality detection signal when the actuating lever reaches the first neutral position.

3. The vehicle door lock device according to claim 1 ,
wherein a first rotating amount of the actuating lever between the first neutral position and the second neutral position is smaller than a second rotating amount of the actuating lever between the first neutral position and the release start position.

4. The vehicle door lock device according to claim 1 ,
wherein the first neutrality detecting switch and the second neutrality detecting switch configure a single switch.
