Abstract: A first determination unit provisionally determines collision or non-collision between a vehicle and another vehicle on the basis of positional information of the vehicle and positional information of the other vehicle. A second determination unit changes a determination result to collision when the provisional determination result has been collision N times in succession and when the determination result was previously non-collision, and changes the determination result to non-collision when the provisional determination result has been non-collision M times in succession and when the determination result was previously collision. Here, N is smaller than M. N and M are positive integral numbers.

Abstract: A vehicle sets a first determination region of a first obstacle and a second determination region, on the basis of a position of the first obstacle. The second determination region is located at a position farther than the first determination region. A reliability of the second obstacle is set to a first reliability in a case where a position of a second obstacle falls outside the first determination region and falls outside the second determination region. The reliability of the second obstacle is set to a second reliability higher than the first reliability in a case where the position of the second obstacle falls within the first determination region or falls within the second determination region. Braking is applied to the vehicle body and/or acceleration of the vehicle body is suppressed, on the basis of the reliability of the second obstacle and the position of the second obstacle.

Abstract: A modulating and demodulating section receives, from another radio device, a packet signal including at least position information of another vehicle in which the other radio device is mounted. A position information acquiring section acquires position information of the vehicle in which the radio device is mounted. An estimating section estimates a time taken for the vehicle and the other vehicle to encounter each other on the basis of these two pieces of position information. A deriving section derives a distance between the vehicle and the other vehicle on the basis of these two pieces of position information. A determining section provides notification of an encounter with the other vehicle in a case where the estimated time is equal to or less than a first threshold value or in a case where the derived distance is equal to or less than a second threshold value.

Abstract: An object detection device includes first and second detectors each configured to detect an object by transmitting an ultrasonic wave in a moving direction of the moving object and receiving a reflected wave of the ultrasonic wave, a second detector, a memory, and a hardware processor coupled to the memory, and configured to: determine that an obstacle is present in the moving direction of the moving object, based on object detection results by the first and second detectors; determine crossing of the obstacle based on object detection results by the first and second detectors in a state in which it is being determined that the obstacle is present; and cause a driving controller mounted on the moving object, to release driving restriction control of restricting movement of the moving object when determining the crossing, or prohibit the driving controller from releasing the driving restriction control under a predetermined condition.

Abstract: A wireless communication device mountable in a vehicle acquires first position information on the vehicle and receives a packet signal from another wireless communication device, the packet signal including second position information on another vehicle in which the other wireless communication device is mounted. The wireless communication device has a storage that stores log information and a controller. The controller predicts whether the vehicle crosses the other vehicle at a point of crossing based on the first position information and the second position information, estimates a structure of crossing corresponding to the point of crossing based on the history information, and determines, when it is predicted that the vehicle crosses the other vehicle at the point of crossing, whether or not to notify a presence of the other vehicle to a driver of the vehicle, in accordance with the structure of crossing corresponding to the point of crossing.

Abstract: A first processor derives a first arrival time to be taken for a vehicle and another vehicle travelling straight ahead to intersect at a point. A second processor derives a second arrival time to be taken for the vehicle and the other vehicle running on a straight line linking the vehicle and the other vehicle to encounter at a point. A third processor derives a first range of travelling directions the vehicle can take between the second arrival time and the first arrival time and derives a second range of travelling directions the other vehicle can take between the second arrival time and the first arrival time. A determiner determines relative relation between the vehicle and the other vehicle at a time of intersection between the vehicle and the other vehicle, based on difference between the first range and the second range.

Abstract: A vehicle control device controls a vehicle on the basis of a detection time representing a distance measured by a range finder device. The range finder device is installed in the vehicle to measure a distance to an object around the vehicle by transmitting and receiving sound waves. The vehicle control device includes a processor that receives an input of a first detection time after movement of the vehicle. The processor outputs an intersection point as coordinates indicating a position of the object when the intersection point is obtained. The intersection point is a point at which an estimated straight line and a first locus intersect. The estimated straight line connects respective positions of the range finder device before and after the movement of the vehicle. The first locus is based on the first detection time.

Abstract: A vehicle control device is disclosed. The vehicle control device controls a vehicle on the basis of one or more detection times each representing a distance measured by a distance measuring device mounted on the vehicle. The distance measuring device measures a distance to an object around the vehicle by transmitting and receiving sound waves. The vehicle control device includes acquisition circuitry and estimated coordinate calculation circuitry. The acquisition circuitry acquires the one or more detection times. The estimated coordinate calculation circuitry calculates estimated coordinates indicating an estimated position of an object in a case where the object is present in a neighborhood of the distance measuring device but a distance to the object is not measured. The estimated coordinates is calculated on the basis of the one or more detection times having been acquired by the acquisition circuitry.
