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: 7337055Abstract: An adaptive control system for an automotive vehicle, which warns of a driver and/or reduces the vehicle speed in consideration of a future trajectory. Receiving from a navigation system node information about nodes within a preview section, a control unit calculates a path radius at each of the nodes within the preview section, and identifies curve sections in accordance with the path radius of the preview section. Subsequently, the control unit estimates a lateral acceleration based on the current vehicle speed and the path radius. Subsequently, the control unit determines an estimated total driver load in accordance with the estimated lateral acceleration. Subsequently, the control unit determines a reference total driver load which is applied to the driver during the host vehicle traveling at an allowable cornering speed. Subsequently, the control unit calculates a driver load deviation between the estimated total driver load and the reference total driver load.Type: GrantFiled: April 22, 2005Date of Patent: February 26, 2008Assignee: Nissan Motor Co., Ltd.Inventors: Shinji Matsumoto, Satoshi Tange, Tatsuya Suzuki, Hiroyuki Yoshizawa

Patent number: 6993425Abstract: A lane deviation avoidance system for an adaptive cruise control system equipped vehicle includes an electronic control unit that executes a host vehicle's lane deviation avoidance control in which a change in vehicle dynamic behavior occurs in a direction that avoids the host vehicle from deviating from a driving lane when there is a possibility of the host vehicle's lane deviation from the driving lane. The control unit puts a priority on the lane deviation avoidance control by limiting a driving force acting on the host vehicle, when there is the possibility of the host vehicle's lane deviation from the driving lane.Type: GrantFiled: February 28, 2003Date of Patent: January 31, 2006Assignee: Nissan Motor Co., Ltd.Inventors: Satoshi Tange, Genpei Naito, Shinji Matsumoto, Hiroyuki Yoshizawa
