Patent number: 5917299Abstract: A motor drive control device, comprises: a switch which operates a motor; a motor which raises and lowers a door glass; a pulse signal generating device which synchronizes with the rotation of the motor and generates a pulse signal; and a determining device which, in a case in which there is a predetermined difference between this pulse signal and a normal pulse signal which is generated by synchronizing with the rotation of said motor, determines that the pulse signal generating device is failed. Therefore, in a case in which it is determined that the pulse signal generating device is failed and the switch is operated so that the motor raises the door glass, raising of the door glass can be stopped.Type: GrantFiled: February 20, 1997Date of Patent: June 29, 1999Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Katsuhide Kumagai, Kanichi Tanaka, Yousuke Obata, Shigeji Ito, Noboru Mizukami, Osamu Inagaki
