Patent number: 8554436Abstract: A vehicle driving assist system has a controller configured to calculate a risk potential indicative of the degree of convergence between a host vehicle in which the system is installed and a preceding obstacle. Then, the controller performs a driver notification controlling operation that produces a driver notification stimulus based on the risk potential. Considering the acceleration of the preceding obstacle, the speed of the host vehicle, and the following distance between the host vehicle and the preceding obstacle, the controller calculates a threshold value for determining when to commence the control of the driver notification controlling operation.Type: GrantFiled: August 3, 2006Date of Patent: October 8, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Yousuke Kobayashi, Genpei Naito, Takeshi Kimura, Hiroyuki Yoshizawa

Patent number: 7826970Abstract: A vehicle driving assist system executes an actuation reaction force control of accelerator pedal, a driving force control or a braking force control in a manner that is appropriate in consideration of the traffic situation in which the vehicle is being driven. The vehicle driving assist system calculates a risk potential that indicates the degree of convergence between the vehicle and an obstacle existing in front of the vehicle based on a prescribed control pattern. Then, based on the risk potential, the accelerator pedal actuation reaction, the host vehicle driving force and/or the host vehicle braking force are controlled. The intent of the driver regarding acceleration and deceleration based on the actuation state of the accelerator pedal is preferably used in controlling one or all of the accelerator pedal actuation reaction, the host vehicle driving force and the host vehicle braking force.Type: GrantFiled: July 6, 2006Date of Patent: November 2, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Yousuke Kobayashi, Genpei Naito, Takeshi Kimura, Hiroyuki Yoshizawa

Patent number: 7580785Abstract: In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control.Type: GrantFiled: April 29, 2008Date of Patent: August 25, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Shinji Matsumoto, Genpei Naito, Satoshi Tange
