Patent number: 7327050Abstract: An electric steering lock device is configured with a control unit to operate a steering column lock between a steering locked state and a steering unlocked state. The electric steering lock device has a locking limit switch that turns on when a locking member reaches the locking stop position, and turns off when an unlocking command for the locking member is outputted. An unlocking limit switch of the electric steering lock device turns on when the locking member reaches the unlocking stop position, and turns off when a locking command for the locking member is outputted. The electric steering lock control unit determines that the locking limit switch or the unlocking limit switch has malfunctioned based on the state of the locking member.Type: GrantFiled: September 30, 2005Date of Patent: February 5, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Yoichi Koga, Tetsuya Asada

Patent number: 6434471Abstract: When a vehicle-to-vehicle time gap is changed from a first level to a second level with a selector switch, a controller determines a desired time gap so that the desired time gap varies from the first level to the second level at such a gradual rate as to prevent an abrupt change in the vehicle speed. The controller further determines a desired vehicle spacing from the controlled vehicle to a preceding vehicle in accordance with the desired time gap and a sensed vehicle speed, and controls the driving force and braking force of the controlled vehicle so as to bring the actual vehicle spacing closer to the desired vehicle spacing.Type: GrantFiled: June 22, 2000Date of Patent: August 13, 2002Assignee: Nissan Motor Co., Ltd.Inventors: Tetsuya Asada, Kenichi Egawa, Akira Higashimata, Satoshi Tange
