摘要： A vehicular control object determination system includes: a radar device for detecting an object that is present in the direction of travel of a vehicle; a travel locus estimator for estimating a future travel locus of the vehicle; and a control object determiner for determining a control object based on a detection result obtained by the radar device, a travel locus estimated by the travel locus estimator. The control object determiner modifies the control object determination conditions when the estimated travel locus is not a straight line and the detected relative sideways speed is less than the threshold value, and when the estimated travel locus is a straight line and the detected relative sideways speed is equal to or greater than the threshold value, thereby preventing erroneous identification of a preceding vehicle traveling on an adjacent lane as a control object.

摘要： In a vehicular control object determination system, the position of an object detected by a radar device is stored by a detection position memory, and a predetermined area having the position of the object as the center is set as the determination region by a determination region setter. When the determination region set for one of two objects is passed through by the other object, the passing direction is determined by a passing direction determiner. During this process, the direction in which a fixed object or an object dropped on the road moves relative to a preceding vehicle is a direction in which the fixed object or the dropped object on the road approaches the subject vehicle with the preceding vehicle as a reference. Then, a control object determiner excludes from determination of the control object an object for which the passing direction determined by the passing direction determiner is a direction approaching the subject vehicle, thereby preventing the fixed object or the dropped object from being erroneously determined as the control object when the preceding vehicle passes over the fixed object or the dropped object on the road.

摘要： When a deceleration intention detector detects that an occupant has apprehension about a condition ahead of his own vehicle and attempts to decelerate the own vehicle, a detection area setter enlarges a detection area in which a control object is detected, upon a command from a control object determinator. Therefore, a new control object such as a cutting-in vehicle can be more reliably detected in accordance with an increase in an amount of attention which the occupant pays to the condition ahead of the own vehicle. As a result, a vehicle controller changes a vehicle control content of the own vehicle, thereby performing an appropriate vehicle control with respect to the newly detected control object to eliminate a sense of discomfort of the occupant.

摘要： A vehicular control object determination system includes: a radar device for detecting an object that is present in the direction of travel of a vehicle; a travel locus estimator for estimating a future travel locus of the vehicle; a control object determiner for determining a control object based on a detection result obtained by the radar device, a future travel locus of the vehicle estimated by the travel locus estimator based on a vehicle speed and a yaw rate and predetermined control object determination conditions; and a swing rate detector for detecting a swing rate of side-to-side swing of the estimated travel locus. When the detected swing rate is equal to or greater than a threshold value, the control object determiner excludes from determination of a control object an object that is further than a predetermined distance. Therefore, when the swing rate is large and the estimation accuracy is lowered, an object that is farther than a predetermined distance is excluded from determination of a control object, thereby avoiding erroneous determination of a control object.

摘要： In a vehicular control object determination system, locus correlation degree calculator calculates a degree of correlation between a future travel locus of a vehicle estimated by first travel locus estimator based on a vehicle speed and a yaw rate and a future travel locus of the vehicle estimated by second travel locus estimator based on a past travel locus of the vehicle calculated by travel locus calculator. When control object determiner determines a control object based on the travel locus estimated by the first travel locus estimator and predetermined control object determination conditions, the control object determination conditions are modified according to the degree of correlation, that is, the degree of reliability of the travel locus estimated by the first travel locus estimator, thereby achieving both accuracy with which the control object is determined and determination of the control object at a distance.

摘要： Stationary objects are determined from objects detected by a radar device mounted on a vehicle. Objects detected with a dispersion in the level of the reception of a reflected wave at a relative distance in a range of 20 m to 100 m that is equal to or smaller than a first threshold value, are extracted from the extracted objects, and objects existing on a predicted course for the vehicle is extracted from the extracted objects. Further, it is determined if one of the extracted objects detected with rate of decrease in level of reception at a relative distance in a range of 10 m to 20 m is equal to or larger than a second threshold value and with a level of reception equal to or smaller than a third threshold value is an object which provides no hindrance even if the vehicle passes over the object. A warning or an automatic braking is discontinued or moderated based on the type of object. Thus, it is possible to precisely determine whether the object detected by the radar device mounted on the vehicle is an object particularly providing no hindrance even if the vehicle travels astride the object as it is, or whether it is an object the contact of the vehicle with which is required to be avoided, thereby carrying out a precise warning or automatic braking.

摘要： A travel controller which controls the travel of a subject vehicle based on a distance to and a relative speed with respect to a control object determined by a control object determiner. If stoppage of the subject vehicle by a decelerating operation of a driver is detected by a manual stoppage detector and a comparator determines that a distance to the object in or on a travel locus is equal to or larger than a determination threshold value, the comparator excludes the object from being considered as a control object.
