Patent number: 7726692Abstract: In a steering handle grasped and rotated by both hands of a driver, an axis of a steering shaft included in the steering handle is inclined so as to be higher in level in a forward direction of a vehicle body, and a left grip grasped by a left hand and a right grip grasped by a right hand are rotatable in opposite directions about an axis perpendicular to the axis of the steering shaft. Accordingly, an upper half of the driver's body sitting on a seat and leaning backwards and a plane of rotation of the steering handle are substantially parallel to each other, thereby ensuring that the driver can rotate the steering handle without stretching and withdrawing his or her arms. Moreover, when the steering handle is rotated, the driver's wrists can be prevented from being twisted unnaturally, leading to an easy steering operation.Type: GrantFiled: October 21, 2004Date of Patent: June 1, 2010Assignee: Honda Motor Co., Ltd.Inventors: Takafumi Ozaki, Paul Baron, Kazuhiko Satou, Tatsuya Amano, Hisao Asaumi, Masaaki Kawano, Hirokazu Kitazawa, Kunio Shirakawa, Osamu Tsurumiya, Yoshinobu Mukai, Kazuhisa Watanabe

Patent number: 7257475Abstract: A vehicle control system is provided for a vehicle that is steered by steer-by-wire, the system including a battery mounted in the vehicle, a steer-by-wire steering system that turns wheels by an electric motor that is operated by electric power supplied from the battery, a steering controller for controlling the operation of the steer-by-wire steering system, and an engine controller for controlling, by electric power supplied from the battery, the operation of an engine for making the vehicle travel. A booster circuit boosts the voltage applied to the steering controller so that, when the voltage of the battery decreases, the voltage applied to the engine controller falls below its minimum operating voltage before the voltage applied to the steering controller falls below its minimum operating voltage. With this arrangement, it is possible to provide fail-safe operation when there is a decrease in the voltage of the battery which supplies electricity to the steering controller.Type: GrantFiled: July 2, 2004Date of Patent: August 14, 2007Assignee: Honda Motor Co., Ltd.Inventors: Hisao Asaumi, Masaaki Kawano, Osamu Tsurumiya
