Patent number: 8324853Abstract: A vehicle wiper controller includes a wiper drive circuit which drives a wiper. An operation switch is manipulated in a plurality of manipulation directions or to a plurality of operation mode positions when a manipulation force is applied thereto. A wiper operation control unit electronically controls the operation of the wiper and sets the wiper to an operation mode corresponding to the manipulation of the operation switch. A control signal hold circuit, discrete from the wiper operation control unit, transmits a control signal to the wiper drive circuit when the operation switch is manipulated in a predetermined first manipulation direction or when the operation switch is manipulated to a predetermined first operation mode position. The control signal hold circuit sets a hold state for holding the transmission state of the control signal.Type: GrantFiled: July 22, 2009Date of Patent: December 4, 2012Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Seiji Ishigaki, Hitoshi Muraki, Masaki Yoshino, Yoshihisa Hirano, Kenji Iwasaki, Kunihiko Ikekame
