Patent ID: 8562034

Claim:
A door lock device for a vehicle comprising: a latch mechanism selectively switched to a fully-latched state for holding a vehicle door in a fully-closed state or a half-latched state for holding the vehicle door in a half-closed state; a closing side transmitting member linked to the latch mechanism; a motor, a driving force of which is transmitted to the latch mechanism via the closing side transmitting member after an idling section, driving to switch the latch mechanism from the half-latched state to the fully-latched state; a rotational speed detecting member for detecting a rotational speed of the motor; a calculating means for calculating the rotational speed difference between the rotational speed of the motor detected in the idling section and a current rotational speed of the motor detected subsequently; a determining means for determining a sandwiching of an object on the basis of a relationship between the calculated rotational speed difference and a threshold value; a temperature estimating means for estimating a temperature of the motor on the basis of the rotational speed of the motor, detected in the idling section; and a correcting means for correcting the threshold value so that a determination sensitivity of the sandwiching of the object becomes greater when the estimated temperature of the motor is low than when the estimated temperature of the motor is high.
