When a defined condition prevails, the first mode switches into a third mode in the form of deceleration, wherein a second selection process is started which also evaluates stationary target objects. Until a target object is selected, the vehicle travels on a clear road with deceleration initiated which is reduced relative to following another vehicle. If a target object is selected by the second selection process, the system switches over without delay from the third mode into the second mode.08-08-2013
20120078484Vehicle cruise control apparatus - In a vehicle cruise control apparatus, a cruise control unit determines whether or not a lane in which a subject vehicle is traveling is an overtaking lane. When the cruise control unit determines that the subject vehicle is traveling in an overtaking lane, the cruise control unit sets a target acceleration such that the responsiveness of a subject vehicle speed to an acceleration side is relatively higher than that when the subject vehicle is traveling in a lane other than the overtaking lane (cruising lane).03-29-2012
20120083987ADAPTIVE CRUISE CONTROL ACCELERATION RATE CONTROL - An adaptive cruise control system for a host vehicle. The adaptive cruise control system includes a sensor and a controller. The sensor is configured to detect a vehicle in front of the host vehicle. The controller receives an indication of the detected vehicle from the sensor and is configured to maintain a speed of the host vehicle at a desired speed, to determine a speed of the detected vehicle relative to the host vehicle, and adjust an acceleration rate of the host vehicle based on the relative speed.04-05-2012
20130211689CRUISE CONTROL APPARATUS - The cruise control apparatus includes a headway control means for making a first determination as to whether or not at least one recognized front vehicle running ahead of an own vehicle is a preceding vehicle present in an own-vehicle lane in which the own vehicle is running, performing a headway control to cause the own vehicle to run following the preceding vehicle when the first determination is affirmative, and a vehicle type recognizing means for recognizing a type of the recognized front vehicle. The headway control means is configured to change a way to perform the headway control depending on the type (vehicle size, for example) of the recognized front vehicle.08-15-2013
