摘要： A travel controller detects a vehicle traveling behind a host vehicle from situation data depending on the situation around the host vehicle; controls travel of the host vehicle to maintain a predetermined distance or more between the host vehicle and the detected vehicle behind; causes the host vehicle to perform a first action when the distance between the host vehicle and the vehicle behind is greater than a distance threshold; causes the host vehicle to perform a second action when the distance is less than the distance threshold, the second action contributing to safe travel of the host vehicle more than the first action; sets the distance threshold at a first value when a travel situation around the host vehicle does not satisfy a predetermined short-distance condition; and sets the distance threshold at a second value smaller than the first value when the travel situation satisfies the short-distance condition.

摘要： A driving support Electronic Control Unit (ECU) initializes a target trajectory calculation parameter at a start of Lane Change Assist Control (LCA), calculates, based on the target trajectory calculation parameter, a target trajectory function representing a target lateral position in accordance with an elapsed time from the start of LCA; and calculates a target control amount according to the target trajectory function. When it is determined that the own vehicle has crossed a boundary white line, the driving support ECU again initializes the target trajectory calculation parameter, and calculate the target trajectory function based on the target trajectory calculation parameter.

摘要： A steering control device includes a driving support ECU. The driving support ECU 10 is configured to execute an original lane return assist control to control a steering so as to return an own vehicle from a target lane to the original lane when a lane change assist control is stopped by detection of a first approaching vehicle in a situation where the own vehicle enters the target lane to travel in the target lane. The driving support ECU is configured to prohibit the original lane return assist control and to execute a lateral speed zero control to control the steering so as to maintain a lateral speed which is a speed in a lane width direction of the own vehicle at zero, when an original lane side vehicle is being detected.

摘要： The first yaw angle return control is started at a first start time when the first interruption condition is established. The actuator is controlled under the first yaw angle return control so that yaw angle at a first finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the first start time. The first finish time comes when a first control execution time passes from the first start time. The actuator is controlled under the second yaw angle return control so that yaw angle at a second finish time becomes a value closer to yaw angle at the lane change start time compared with yaw angle at the second start time. The second finish time comes when a second control execution time longer than the first control execution time passes from the second start time.

摘要： A vehicle control device comprises a processor configured to determine a target merge location where the vehicle is to make a lane change from a merging lane to a main lane, in a merge zone on a scheduled route where the merging lane merges with the main lane, as a location that is before the location at the minimum distance to the end point of the merging lane allowing the driver to whom control of the vehicle has been handed over to operate the vehicle for the lane change, and when the vehicle has not completed the lane change upon reaching the target merge location, give the driver a first notification notifying that control of the vehicle will be switched from automatic control to manual control, by using a notifying unit that notifies the driver of information, or by using a vehicle controlling device that controls operation of the vehicle to perform a predetermined operation of the vehicle.

摘要： A yaw angle return controller is configured to end first yaw angle return control at a predetermined time when a value which is calculated by adding yaw angle detected by a lane recognition device at a predetermined time and an estimated yaw angle change amount is the same as yaw angle at lane change start time under a state where the first yaw angle return control is being executed. The predetermined time comes after the first start time and before the first finish time. The estimated yaw angle change amount is calculated by multiplying the yaw rate detected by a yaw rate sensor at the predetermined time by a predetermined time period for foreseeing.

摘要： A steering control device includes a driving support ECU. When white line recognition loss, which is a state in which white lines are not properly recognizable, has occurred during execution of an LCA, the driving support ECU calculates a target trajectory for returning a yaw angle to a state immediately before the start of the LCA. The driving support ECU controls a steering angle based on the calculated target trajectory. As a result, a lateral speed of an own vehicle is reduced, and thus sufficient time can be secured for handing over operation of a steering wheel to a driver from a steering assist state.
