Patent number: 11680572Abstract: A position deviation calculated by a subtractor of a vacuum pump is input to the PIDs of three modes. The first PID is a PID controller for a high-bias mode, the second PID is a PID controller for a high-rigidity mode, and the third PID is a PID controller for a low-rigidity mode. The output signal of the third PID is extracted as a change of an indicator current for each clock of a PWM frequency and then the mean value of a change of an indicator current for several clocks is determined in a calculating unit. At this point, a switching control unit performs an operation on whether the mean value of the averaged change of the indicator current is larger than a preset redetermined value and then according to the result, an ? value is outputted in the range of 0 to 1 from the switching control unit.Type: GrantFiled: August 24, 2018Date of Patent: June 20, 2023Assignee: Edwards Japan LimitedInventors: Yoshimasa Ezawa, Hideo Fukami, Kou Sato

Patent number: 8700305Abstract: A driving control device according to the present invention activates a control for suppressing sideways movement of a vehicle towards a side object, when the side object present to the side of the vehicle as well as towards the rear of the vehicle is detected. Also, the activation of the control is suppressed when, in the absence of detection of the side object, the vehicle starts entering an adjacent lane in order to change lanes.Type: GrantFiled: December 1, 2010Date of Patent: April 15, 2014Assignee: Nissan Motor Co., Ltd.Inventors: Yasuhisa Hayakawa, Kou Sato, Masahiro Kobayashi

Patent number: 8577515Abstract: A driving assisting system for a vehicle comprises a side obstacle detector configured to detect an obstacle present in an obstacle detection area; an obstacle approach prevention controller configured to implement an obstacle approach prevention control which assists an approach prevention for preventing the vehicle from approaching an obstacle detected by the side obstacle detector; an overtaking state detector configured to detect an overtaking state which is at least one of a first state where the vehicle is overtaking the obstacle detected by the side obstacle detector and a second state where the vehicle is estimated to overtake the obstacle. The overtaking state detector is configured to detect the overtaking state based at least on (i) a distance between the vehicle and the obstacle, (ii) a speed of the vehicle relative to the obstacle, and (iii) a detection angle of the obstacle relative to the vehicle.Type: GrantFiled: July 15, 2010Date of Patent: November 5, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Masahiro Kobayashi, Yasuhisa Hayakawa, Kou Sato

Patent number: 8346437Abstract: When a lane-width-direction lateral position (X2obst+X0) of a vehicle (MM) reaches a predetermined control start position (60) being a lane-width-direction lateral position (X2obst+X0) serving as an approach prevention indicator for the vehicle (MM), a control start is determined and a yaw moment (Ms) toward the center of a vehicle traveling lane (200) is applied to the vehicle (MM) to control the vehicle (MM). Then, when the lane-width-direction lateral position (X2obst+X0) of the vehicle (MM) moves from the outside to the inside of the control start position (60), the determination of control start is suppressed for a predetermined period, compared to a period before the movement to the inside of the control start position (60).Type: GrantFiled: July 29, 2010Date of Patent: January 1, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Yasuhisa Hayakawa, Kou Sato, Masahiro Kobayashi

Publication number: 20120166017Abstract: An overtaking state is detected which is at least one of a first state where an own vehicle (MM) is overtaking an obstacle (SM) in a posterolateral direction of the own vehicle (MM) and a second state where the own vehicle (MM) is estimated to overtake the obstacle (SM). In the implementation of an obstacle access prevention control for preventing the own vehicle (MM) from accessing the obstacle (SM) present in the posterolateral direction of the own vehicle (MM), when a determination that the overtaking state is established is made based on the detecting, the obstacle access prevention control with respect to the obstacle (SM) is suppressed compared with when the determination that the overtaking state is established is not made.Type: ApplicationFiled: July 15, 2010Publication date: June 28, 2012Applicant: Nissan Motor Co., Ltd.Inventors: Masahiro Kobayashi, Yasuhisa Hayakawa, Kou Sato
