Title:
開閉体の挟み込み検知装置
Document Type and Number:
Japanese Patent JP4802381
Kind Code:
B2
Abstract:
An entrapment detection device of an opening/closing member which efficiently performs an entrapment determination and restrains an entrapment load even when a motor rotational signal is not inputted. The entrapment detection device includes a controller for performing the entrapment detection based on detected motor rotational signal cycle changes outputted from a motor rotation sensor which is synchronized with the movement of a motor for actuating an opening/closing member. The controller stores the cycle changes of a predetermined number of output pulses from the sensor, predetermines a standard cycle time Tb from the stored pulse output, and calculates a cycle coefficient of the entrapment. When the motor rotational speed is reduced, an entrapment detection operation is performed by comparing a value of time from a previous cycle change to a current cycle change multiplied by the calculated cycle coefficient with the standard cycle Tb.
