In a driving assist apparatus for assisting a lane change from an own lane to a target lane, when a post-smoothing probability obtained by smoothing a time course change in a lane presence possibility which increases with the possibility that a target is another vehicle traveling in the target lane (target lane other vehicle) is greater than a threshold value, that target can be extracted as the target lane other vehicle. The post-smoothing probability requires some length of time to coincide with the lane presence possibility. Therefore, if after completion of a lane change, another lane change is immediately started in the same direction, there arises a possibility that the target lane other vehicle cannot be extracted properly. Therefore, in the case where after completion of a lane change, another lane change is started in the same direction, the lane change is not started until a re-change prohibition time elapses.

The present disclosure provides systems and methods for an adaptive cruise control that controls a speed of a host vehicle as a passing vehicle quickly passes through a trajectory of the host vehicle. In one form, a system includes at least one processor that is configured to determine that a passing vehicle is entering a trajectory in which the host vehicle is travelling based on a longitudinal speed, a longitudinal acceleration, a lateral speed, and a lateral acceleration of the passing vehicle; determine to maintain a follow distance of an adaptive cruise control system of the host vehicle to at least one target vehicle in the trajectory in which the host vehicle is traveling prior to the passing vehicle entering the trajectory; and to maintain the follow distance to the at least one target vehicle while the passing vehicle passes through the trajectory in which the host vehicle is traveling.

A vehicle and an adaptive cruise control system (ACC) is provided. The ACC comprises a steering wheel system with a steering wheel arranged to allow the provision of manual steering input to the steering system of the vehicle and a steering angle sensor, wherein the steering system is configured to identify a specific momentary manual steering wheel actuation by comparing data from the steering angle sensor with predetermined thresholds, and to select a next one of the moving or stationary objects in the surroundings in front of said vehicle to control the speed of said vehicle in relation to, based on the direction of the specific momentary manual steering wheel actuation indicated by the steering angle sensor.

A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to monitor conditions of a roadway as a vehicle travels the roadway while an adaptive cruise control feature of the vehicle is active, identify an expected condition change based on the monitoring the conditions of the roadway, determine a preferred power state for an engine of the vehicle based on the expected condition change, determine that an engine power state transition is planned for the engine, the engine power state transition including transitioning the engine from a current power state to a planned power state, and resolve the engine power state transition based on the preferred power state.

In a driving assist apparatus for assisting a lane change from an own lane to a target lane, when a post-smoothing probability obtained by smoothing a time course change in a lane presence possibility which increases with the possibility that a target is another vehicle traveling in the target lane (target lane other vehicle) is greater than a threshold value, that target can be extracted as the target lane other vehicle. The post-smoothing probability requires some length of time to coincide with the lane presence possibility. Therefore, if after completion of a lane change, another lane change is immediately started in the same direction, there arises a possibility that the target lane other vehicle cannot be extracted properly. Therefore, in the case where after completion of a lane change, another lane change is started in the same direction, the lane change is not started until a re-change prohibition time elapses.

In a method for automatically adjusting the vehicle speed of a vehicle, while the distance to a preceding other vehicle is continuously measured, in order to reduce an initial distance, the vehicle is initially moved, in a drive phase, at a higher vehicle speed and is subsequently decelerated in a braking phase.

A control device for vehicle travelling is provided, which executes following control that controls a vehicle speed in accordance with a following distance from a preceding vehicle. The following control includes LK following control that is executed so that a following distance from a preceding vehicle on a travel lane becomes an LK target following distance, under a situation of lane keep. The following control farther includes LC following control that is executed so that a following distance from a vehicle to be a preceding vehicle on a target lane becomes an LC target following distance, under a situation of lane change. In the LC following control, a vehicle speed is controlled so that a larger value is allowed as compared with at a time of execution of the LK following control, with respect to one or both of an acceleration and a jerk.

A vehicle control system includes: a first switch that accepts an operation of an occupant of a vehicle; and a performance part that performs, when the first switch is operated, travel assist in a node in which an assist degree is the largest at that time point.

A driving assistance device includes one or more processors configured to control operation of a host vehicle. The one or more processors are configured to perform first following control controlling acceleration and deceleration of the host vehicle so that the host vehicle follows a first preceding vehicle running in front of the host vehicle in the same lane as the host vehicle, and perform second following control prohibiting the first following control while a lane change is being performed and controlling acceleration and deceleration of the host vehicle so that the host vehicle follows a second preceding vehicle running in front of the host vehicle in a destination lane, if the lane change of the host vehicle is started during the first following control.

A vehicle traveling control apparatus of the invention executes a following-travel inter-vehicle-distance control for controlling acceleration and deceleration of an own vehicle such that an inter-vehicle distance between the own vehicle and a preceding vehicle is maintained at a target distance. The apparatus sets the target distance to a base distance and executes the following-travel inter-vehicle-distance control when the driver is determined not to be under the abnormal state. The apparatus sets the target distance to an increased distance larger than the base distance and executes the following-travel inter-vehicle-distance control when the driver is determined to be under the abnormal state.
