Patent number: 8112197Abstract: A wiper apparatus includes: a wiper blade driven by a first motor; and a wiper blade driven by a second motor. The motors are drive-controlled by control microcomputers, respectively. The control microcomputers are connected to each other through a communication line. While exchanging position information of the wiper blades through the communication line, the control microcomputers synchronously drive the motors on the basis of a position relationship between both of the wiper blades. When an abnormality occurs in a communication state of an in-vehicle LAN, a setting state of a wiper switch is grasped through a switch signal line directly connected to the wiper switch, and wipers are prevented from being stopped when such communication abnormality occurs.Type: GrantFiled: November 12, 2008Date of Patent: February 7, 2012Assignees: Mitsuba Corporation, Honda Motor Co., Ltd.Inventors: Toshiyuki Amagasa, Takashi Kondo, Toru Namiki

Patent number: 7895701Abstract: An opposite type wiper apparatus which can prevent interference of each wiper blade even if reference position data is lost. When at least one of reference position data memory sections is in abnormal condition, angle range calculation sections correct operation angle ranges of a DR-side and an AS-side wiper motor so as to shift an upper and a lower reversal positions of a DR-side and an AS-side wiper blade toward storage positions, and so as to make a correction value from the AS-side angle range calculation section larger than a correction value from the DR-side angle range calculation section. Therefore, even when reference position data individually memorized in reference position data memory sections are lost, the DR-side and the AS-side wiper blades can be prevented from interfering with each other.Type: GrantFiled: November 11, 2008Date of Patent: March 1, 2011Assignees: MITSUBA Corporation, Honda Motor Co., Ltd.Inventors: Toshiyuki Amagasa, Takashi Kondo, Toru Namiki

Patent number: 6288509Abstract: In an opposed wiping type wiper apparatus, left and right wiper blades which perform wiping operations with a predetermined preceding-following relationship maintained are layered vertically at their lower returning positions. A wiper drive control unit controls preceding-following relationships between the left and right wiper blades to prevent locking and stopping of the wiper blades when the relationship has changed by replacing left and right control forms for the blades. When the timer of the wiper blade which is to be in the follower side during normal operation is not reset but overflows among timers which are respectively reset pulse signals generated in accordance with rotations of motors, the output of the motor which drives the wiper blade which is to be in the follower side during normal operations is increased.Type: GrantFiled: April 13, 1999Date of Patent: September 11, 2001Assignee: Mitsuba CorporationInventor: Toshiyuki Amagasa
