Abstract: An active vibration controller has: a sensor configured to measure a physical quantity related to vibration of a vehicle body; an actuator arranged on a floor panel of the vehicle body and configured to deform itself to thereby deform the floor panel; and a control unit configured to control the actuator according to the measured physical quantity in such a way as to reduce noise caused by the vibration of the vehicle body. The actuator is installed on a member of the floor panel whose rigidity is greater than an average rigidity of the entire floor panel.

Abstract: A model predictive control apparatus includes an initial solution generation section, an abnormality handling section, and an objective function adjustment section. The abnormality handling section performs initial solution generation when it is determined that performed optimization is abnormal. The initial solution generation section generates an initial optimal value of a future time series control input in accordance with an initial objective function, without reference to a candidate value of the time series control input. The objective function adjustment section adjusts the current objective function so that the current objective function varies stepwise with time toward the normal objective function when it is determined that the current objective function is different from the normal objective function.

Abstract: A lane change assist system is comprised of a host vehicle state detecting device that detects a host vehicle traveling condition, a surrounding vehicle detecting device that detects other vehicle located around the host vehicle, a lane detecting device that detects a lane around the host vehicle, and a processing unit. The processing unit is arranged to set a target lane, to determine a period of a lane change assist, to set a predicted period for an evaluation of a lane change to the target lane based on a prediction, to obtain an appropriate speed range during the predicted period for each gap, and to select a target vehicle speed from the appropriate speed range.

Abstract: A method improves operator assistance of an automobile. On substantially real time basis, data on the automobile and on intervehicle relationship involving the automobile are collected. The data are processed to determine variables for evaluation. The determined variables are evaluated to recommend control input.

Abstract: A lane-changing support system includes a processing unit sets an assumed traffic-merging end, predicts a driving behavior of each peripheral vehicle, and generates at least one host vehicle's manipulated-variable time series to be executed until the host vehicle reaches the assumed traffic-merging end. The processing unit determines whether the host vehicle's lane change is appropriately achievable when executing the manipulated-variable time series, and additionally determines which of gaps defined between the peripheral-vehicles traveling on a traffic lane of destination of lane-changing should be suited for an entry of the host vehicle in case of a decision result that the appropriate lane change is achievable by execution of the manipulated-variable time series. The processing unit transmits information regarding a correspondence between a current host vehicle's manipulated variable on the manipulated-variable time series and at least one lane-changing enabling gap to the driver.

Abstract: In system and method for improving operator driving assistance of an automotive vehicle, at an indication of acceleration timing and magnitude and the lane change timing, a lane change necessity is calculated and a lane change trigger signal is produced while the host vehicle is operated on a road that has at least three lanes and, at the calculation of the lane change necessity and at the production of the lane change signal, a new lane change trigger signal is prohibited to indicate until a forward lane change operation is deemed to be completed, in a case where the vehicle is traveling on a multiple number traffic lane road.
