Abstract: A remote assistance device includes a prediction unit that predicts an assistance provision probability that assistance for a vehicle will be necessary and a priority of the necessary assistance, which are associated with assistance contents of point information, based on a travel route including assistance points and the location information on the assistance points, and a reservation unit that determines whether a reservation for assistance by an operator is necessary based on the assistance provision probability and the priority, and sets, if the reservation is necessary, a reservation for assistance for not assigning an assistance task to the operator even when a low-priority assistance request is newly made while the reservation is held.

Abstract: In a travel assist system, a travel assist control unit selectively performs an off-peak task upon receiving at least one assistance request during an off-peak situation where there are a predetermined number of free operators included in a first group. The off-peak task assigns the at least one assistance request to a selected one of the free operators included in the first group. The travel assist control unit selectively performs an on-peak task upon receiving the at least one assistance request during an on-peak situation where there are not the predetermined number of the free operators included in the first group. The on-peak task analyzes assignment of the at least one assistance request to a selected one of second operators included in a second group in accordance with a priority level of the at least one assistance request.

Abstract: A monitoring center communicates with an autonomous vehicle via a network to monitor the autonomous vehicle. The monitoring center includes a communication unit that receives data regarding a vehicle state from the autonomous vehicle, a determination unit determines whether a state of the autonomous vehicle satisfies a condition for assistance by an operator based on the data regarding a vehicle state, and an operator cooperation unit that notifies the operator of an assistance request if it is determined that the condition is satisfied. The determination unit performs the determination based on a condition different from the last condition if a situation in which the autonomous vehicle is placed is not changed from when an assistance request is issued last time.

Abstract: A remote assistance apparatus records, in an assistance content recording unit, assistance contents for remote assistance for an autonomous driving vehicle in response to the autonomous driving vehicle stopping as a result of an occurrence of a traveling abnormality, and then resumes autonomous traveling as a result of remote assistance for the autonomous driving vehicle being provided by an operator. The assistance contents include an assistance location and operator instruction contents for remote assistance instructed by the operator. The remote assistance apparatus detects an autonomous driving vehicle that is expected to pass through a predetermined assistance location included in predetermined assistance contents recorded in the assistance content recording unit.

Abstract: A remote monitoring apparatus includes an assistance request receiving unit, an object information receiving unit, a determining unit, a past image receiving unit and an operator collaboration unit. The assistance request receiving unit receives an assistance request transmitted from an autonomous vehicle. The object information receiving unit requests, before the assistance request is sent to an operator, the autonomous vehicle to transmit object information and receives it from the autonomous vehicle. The determining unit determines, based on the object information, whether at least one past image is required. The past image receiving unit requests, upon determination by the determining unit that at least one past image is required, the autonomous vehicle to transmit the at least one past image and receives it from the autonomous vehicle. The operator collaboration unit sends the at least one past image along with the assistance request to the operator.

Abstract: A data collection system includes: a communication terminal in each vehicle having a storage processor storing specific sensing information in a storage device and a vehicle-side communication unit; and a data center including a data center-side communication unit and a data center-side storage. The vehicle-side communication unit sequentially transmits vehicle information including a vehicle position to the data center. The data center-side communication unit transmits a transmission request of object information as the specific sensing information to an object vehicle, which is one of the vehicles approximately at a traveling position specified based on the vehicle position. The vehicle-side communication unit transmits the object information to the data center.

Abstract: A radio communication terminal comprises a data classification part, a data value unit price determination part, a transmission value unit price determination part, a transmission order control part, a resource allocation part and a transmission part. The data classification part acquires transmission data from a data supply source, classifies the transmission data by priority class based on a communication quality request, which is determined by types of the transmission data, and stores the transmission data in a priority buffer in correspondence to the priority class. The data value unit price determination part determines a data value unit price of the transmission data. The transmission value unit price determination part determines a transmission data value unit price based on the data value unit price. The transmission order control part assigns a transmission order to the transmission data having the transmission data value unit price higher than a predetermined transmission threshold value.

Abstract: A positioning apparatus is mounted to an own vehicle, and performs positioning of the own vehicle. The positioning apparatus acquires a light reception pattern. The light reception pattern indicates a pattern of a change in strength of reflected light in relation to a position of the own vehicle. The reflected light is obtained using a light wave for measurement that has been transmitted from the own vehicle. The positioning apparatus estimates a position of the own vehicle by referencing a database in which a reference pattern is recorded in advance, and by comparing the light reception pattern and the reference pattern. The reference pattern indicates a pattern in which a strength of reflected light is associated with each position in which a vehicle travels.

Abstract: A wireless positioning terminal includes a wireless receiver receiving reception signals from a wireless transmitter via multiple communication links. A multi-link-base reception informational item is determined by evaluating reception signals via the communication links. The multi-link-base reception informational item, which has a value varying with a position of the wireless positioning terminal, varies with the position differently from an informational item of a reception signal via one of the communication links. A base trajectory is stored which represents correspondence relation about points between (i) a position of the wireless positioning terminal and (ii) the multi-link-base reception informational item. A measured trajectory is generated which represents correspondence relation about points between (i) a calculated position variation and (ii) the multi-link-base reception informational item.

Abstract: An apparatus installed on a host vehicle derives travel locus/condition information relating each of a plurality of reception positions on the vehicle to a corresponding reception condition (e.g., received signal strength), and updates the information at each of successive positions along a travel locus of the vehicle. The currently obtained information is compared with reference travel locus/condition information previously obtained by travel along a reference travel locus, in the same travel direction, by the host vehicle or similar vehicle. Degrees of similarity between the currently obtained information and the reference information are evaluated, and the results used to detect changes in position of the host vehicle along a direction at right angles to its advancement direction.
