Patent number: 7352148Abstract: An optical axis controller and method for headlamps for a vehicle where the swiveling lamps are not driven due to the minute steering operation of the driver. The steering angle of the steering wheel is detected by using, for example, a steering angle signal from a steering angle sensor. A desired light emission direction is computed based on the steering angle and a hysteresis value and the lamps are driven to an actual light emission direction matching the desired light emission direction.Type: GrantFiled: August 25, 2006Date of Patent: April 1, 2008Assignee: Nissan Motor Co., Ltd.Inventor: Takenori Hashizume

Patent number: 6985805Abstract: In an adaptive cruise control (ACC) system with object detection system interaction, capable of executing a vehicle speed holding mode, a constant-speed control mode, and a following control mode, a lane-change detector is provided to detect the presence or absence of a driver's intention for a lane change by the host vehicle. An ACC unit executes the vehicle speed holding mode during which the host vehicle's speed is restricted until such time that a predetermined holding time has expired from a time when the object detection system loses the preceding vehicle during the following control mode, and thereafter executes the constant-speed control mode during which the host vehicle's speed is automatically accelerated up to a set speed. The ACC unit releases the vehicle speed holding mode, in presence of the driver's intention for the lane change when the object detection system loses the preceding vehicle during the following control mode.Type: GrantFiled: June 11, 2003Date of Patent: January 10, 2006Assignee: Nissan Motor Co., Ltd.Inventors: Hideki Sudou, Takenori Hashizume
