摘要： A vehicle control device has a processor configured to estimate an amount of rainfall per unit time based on an acoustic signal acquired by an acoustical sensor mounted on a vehicle, determine whether a present operation mode of the vehicle is a first operation mode with a lower level to which a driver is contributing to driving or a second operation mode with a higher level to which the driver is contributing to driving than the first operation mode, and decide a first time until the operation mode of the vehicle is transferred from the first operation mode to the second operation mode based on the amount of rainfall, when the operation mode of the vehicle is the first operation mode.

摘要： When an object that may possibly collide with a vehicle is detected from a sensor signal of one of sensors mounted on the vehicle, a vehicle controller changes the level of autonomous driving control applied to the vehicle from a first level that does not require a driver to operate an accelerator and steering and does not require the driver to look around the vehicle to a second level that requires the driver to look around the vehicle but does not require the driver to operate an accelerator and steering. When an object that may possibly collide with the vehicle is detected from sensor signals of two or more of the sensors, the vehicle controller changes the level of autonomous driving control from the first level to a third level that requires the driver to operate at least an accelerator or steering.

摘要： A vehicle controller includes a processor configured to detect a vehicle ahead of a host vehicle from time-series sensor signals obtained by a sensor provided on the host vehicle for sensing objects around the host vehicle, track the vehicle ahead detected from the time-series sensor signals, determine whether the vehicle ahead has performed an avoidance action, based on the result of tracking, detect, when the vehicle ahead has performed an avoidance action, a trajectory of an edge of the vehicle ahead opposite a direction of avoidance in the avoidance action, and control travel of the host vehicle so that an edge of the host vehicle opposite the direction of avoidance moves along the detected trajectory.

摘要： An anomaly detection device includes a processor configured to extract a feature indicating the condition of a road surface by inputting an image representing surroundings of a vehicle into a feature extractor that has been trained to extract the feature, detect an abnormal condition in which the vehicle is unable to travel normally, when the feature is outside a normal range that is a tolerable range in which the vehicle is able to travel normally, and modify the normal range, based on the distribution of normal travel features each indicating the condition of a road surface and extracted from the respective images obtained while the vehicle travels normally.

摘要： A vehicle control device has a processor configured to estimate a direction of a source of a warning sound generated by another vehicle relative to the host vehicle based on an acoustic signal acquired by an acoustical sensor, and decide to drive the host vehicle in a direction perpendicular to a current traveling direction of the host vehicle and away from the source of the warning sound, when the direction of the source of the warning sound relative to the host vehicle is estimated.

摘要： An apparatus for object detection detects a number of lanes included in a road on which a vehicle is traveling, detects one or more surrounding vehicles positioned in surroundings of the vehicle from a surrounding image showing the surroundings of the vehicle generated by a camera mounted in the vehicle, and determines, when more surrounding vehicles than the number of lanes detected in a predetermined range at the back of the vehicle are detected alongside in a width direction of the vehicle, that a possibility that any one of the surrounding vehicles being an emergency vehicle which is allowed to travel without obeying the traveling rule of the road is higher than when more surrounding vehicles than the number of lanes are not detected alongside in a width direction of the vehicle.

摘要： An anomaly detection device includes a processor configured to identify a path region in an image representing surroundings of a vehicle, the path region representing a host vehicle lane on which the vehicle is traveling, extract a feature indicating the condition of a road surface regarding the path region from the image by inputting the path region in the image into a feature extractor that has been trained to extract the feature, and detect an abnormal condition in which the vehicle is unable to travel normally on the host vehicle lane, when the feature is outside a normal range that is a tolerable range in which the vehicle is able to travel normally.

摘要： A vehicle controller includes a processor configured to estimate the position of a vehicle by comparing an image representing an area around the vehicle generated by a camera mounted on the vehicle with map information, set a planned trajectory of the vehicle along a lane including the estimated position of the vehicle by referring to the map information, detect a stationary object in the area around the vehicle from the image or a ranging signal obtained by a distance sensor mounted on the vehicle for detecting the distance to an object in the area around the vehicle, determine whether the detected stationary object is on the planned trajectory, and determine that the estimated position of the vehicle is incorrect, when the stationary object is on the planned trajectory.

摘要： A sound control device has a processor configured to determine whether a driving mode of a vehicle is a first driving mode wherein degree to which the driver participates in driving is low or a second driving mode wherein the degree to which the driver participates in driving is higher, and decide to cause attenuation of predetermined sounds inside the vehicle in a first attenuation mode, using a sound control unit which generates a suppression sound signal for output of suppression sound to cause attenuation of the predetermined sounds, when the driving mode of the vehicle is the first driving mode, or decide to cause attenuation of the predetermined sound inside the vehicle in a second attenuation mode which has a smaller degree of attenuation than the first attenuation mode, when the driving mode of the vehicle is the second driving mode.
