Abstract: A platooning system includes a vehicle control system installed in each of vehicles that include a manually-driven head vehicle. The vehicle control system controls a host vehicle such that the host vehicle follows a lead vehicle through wireless communication between the host vehicle and the lead vehicle. The vehicle control system is installed in the host vehicle and the lead vehicle. The vehicle control system includes a sensor that detects a state of the host vehicle, an actuator that adjusts a behavior of the host vehicle, and a controller that controls the host vehicle. The controller of the head vehicle physically notifies a driver of the host vehicle of a state of a subsequent vehicle by operating the actuator of the host vehicle when a state signal including information that indicates the state of the subsequent vehicle is received through the wireless communication.

Abstract: A driving support apparatus installed in a host vehicle calculates an overlap ratio relating to a target object positioned ahead of the host vehicle within the same traffic lane, as the ratio of the width of the target object to its lateral distance from a lane marker line of the traffic lane, and also detects the motion condition of the object (i.e., stationary, moving towards, or in the same direction as the host vehicle, or moving laterally with respect to the forward direction of the host vehicle). An amount of compensation for retarding or advancing the commencement of a collision avoidance operation by the driving support apparatus is determined based on the overlap ratio and/or the motion condition of the target object.

Abstract: A method and an apparatus are provided to recognize a shape of a road on which a vehicle is traveling. Road edge shapes on a left side and a right side of the vehicle are recognized, from positions of roadside objects detected based on detection information from an on-board radar. Lane shapes that are shapes of lane boundary lines on the left side and the right side of the vehicle are recognized, from positions of lane boundary lines detected based on an image captured by an on-board camera. For each of the left side and the right side, such that the recognized road edge shape and the recognized lane shape are compared with each other, and the road shape is identified based on the comparison results.

Abstract: A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.

Abstract: A collision avoidance ECU sets a target relative deceleration to a first target value when a brake control starting condition is satisfied, and carries out a first brake control for bringing a relative deceleration closer to the target relative deceleration. When a reference relative deceleration with reference to the relative deceleration at a first point in time has reached a specified relative deceleration, the collision avoidance ECU determines a greater value for a second target value when the amount of change in deceleration, which is the amount of change in the reference relative deceleration at the point in time, is small than when the amount of change in deceleration is large. The collision avoidance ECU then sets the target relative deceleration to the second target value, and carries out a second brake control for bringing the relative deceleration closer to the target relative deceleration.

Abstract: An ECU calculates: a free running distance, which is a distance that a vehicle can travel from a first time point at which a speed-reduction control is started to a second time point at which the relative deceleration begins to increase by the start of the speed-reduction control; an increase travel distance, which is a distance that the vehicle can travel from the second time point to a third time point at which the relative deceleration reaches the target relative deceleration; and a post-completion travel distance, which is a distance that the vehicle can travel from the third time point to a time point at which the relative speed is made equal to or less than the specified speed. The ECU obtains a speed reduction distance based on a result of adding up the free running distance, the increase travel distance, and the post-completion travel distance.

Abstract: When the vehicle decelerates on the ascending slope, a required brake axle torque is calculated in accordance with vehicle deceleration, so that the swinging back is suppressed. At start timing after that, initial and final values of the required brake axle torque and a correction duration are determined. During the correction duration from the start timing, the required brake axle torque is decreased from the initial value to the final value. Then, based on change in a detected vehicular speed at or before a time which is a last moment of a period in which the detected vehicular speed detected based on detection signals of the wheel speed sensors are equal to or larger than a minimum detectable vehicular speed, a stop time at which an actual vehicle speed becomes zero is estimated, a period from the start time to the stop time is identified as the correction duration.
