Publication number: 20140200768Abstract: In a vehicle travel assisting device, a vehicle speed, a yaw rate, a traveling lane of an own vehicle, and a position of a leading vehicle are detected. Target travel coordinates of the own vehicle are calculated, based on the traveling lane and the position of the leading vehicle A travel path curvature of a target travel coordinate group is estimated, based on information related to the target travel coordinate group. A steering quantity to be steered in advance by the own vehicle is calculated, based on the currently estimated travel path curvature. A weight for each of the target travel coordinates for estimating the travel path curvature is adjusted based on the vehicle speed, the yaw rate and the previously estimated travel path curvature. Steering control is performed such that the own vehicle travels so as to follow the estimated travel path curvature, based on the calculated steering quantity.Type: ApplicationFiled: January 9, 2014Publication date: July 17, 2014Applicant: DENSO CORPORATIONInventors: Tomohiko Tsuruta, Yusuke Ueda, Takeshi Hatoh, Takayuki Kondoh, Naoya Inoue

A posture detection section detects a vehicle posture state indicated by a lateral position and an angle of yaw. An offset distance detection section detects an offset distance between the basis route and the lateral position. A correction steering amount calculation section calculates a correction steering amount as a steering control amount to drive the own vehicle along a virtual correction route. The posture of the own vehicle is alien with a predetermined target posture at a predetermined virtual target point by using the virtual correction route.

Publication number: 20140180569Abstract: A selection track setting section in a driving route generation device determines as a selected track a track of a preceding vehicle when a detection section and a track generation section detects a track of the preceding vehicle which is running on the same driving lane of a host vehicle. A candidate track selection section outputs as a candidate track one of tracks of front vehicles, detected by the detection section and the track generation section, other than the track of the preceding vehicle. A switching selection section switches as the selected track from the track of the preceding vehicle to the candidate track when a detection of the track of the preceding vehicle is interrupted during a predetermined detection period. An estimate route generation section generates an estimated driving route of the host vehicle on the bass of the selected track.Type: ApplicationFiled: December 18, 2013Publication date: June 26, 2014Applicant: DENSO CORPORATIONInventors: Yusuke Ueda, Tomohiko Tsuruta, Takeshi Hatoh, Takayuki Kondoh, Naoya Inoue

Patent number: 8577566Abstract: A driving instability determination device is provided to improve the precision in detecting the driving instability. The driving state determination section determines whether the state is a prescribed driving state by determining whether the information of the operation state of the driving operation unit and the vehicle state as the running state data is disturbed. Based on the running state data for detecting the unstable state of the driver, the running state distribution computing section excludes the running state data when the state is determined to be the prescribed driving state, and the running state distribution computing section computes the first and second running state distributions in different time ranges. The driving instability determination section determines the instability of the driving from the difference between the two computed running state distributions.Type: GrantFiled: April 24, 2012Date of Patent: November 5, 2013Assignee: Nissan Motor Co., Ltd.Inventor: Takayuki Kondoh

Patent number: 7734419Abstract: A vehicle driving assist system is configured to convey a risk potential relating to a preceding obstacle to a driver using both visual information and haptic information. For example, the vehicle driving assist system executes accelerator pedal actuation reaction force control such that an actuation reaction force is generated in accordance with a risk potential that expresses a degree of convergence between the host vehicle and a preceding obstacle. In order to convey to the driver in a clear manner which preceding obstacle(s) is an obstacle targeted by the risk potential calculation and the reaction force control, the system displays a reference frame or marker at a position corresponding to the targeted obstacle (preceding vehicle). At least one of size, color, shape and brightness of the marker is set in accordance with the risk potential.Type: GrantFiled: November 6, 2006Date of Patent: June 8, 2010Assignee: Nissan Motor Co., Ltd.Inventor: Takayuki Kondoh
