摘要： A server receives video data from a moving body. A traveling speed control apparatus controls a traveling speed of the moving body. A quality monitoring unit monitors video quality of the video data received by the server. A speed upper limit calculation unit calculates, by using the video quality and a monitoring required condition of the video data, a maximum value of a traveling speed satisfying the monitoring required condition as an upper limit value of a traveling speed of the moving body. A speed control unit controls a traveling speed of the moving body to be equal to or lower than the calculated upper limit value.

摘要： A vehicle configured to so as to be able to be remotely driven transmits information about each vehicle to a vehicle control apparatus through a network. In the vehicle control apparatus, an analysis unit receives information about each vehicle. The analysis unit analyzes state information of each vehicle based on the received information about each vehicle. Each remote control unit performs at least one of remote monitoring or remote control for at least one of a plurality of vehicles. An assignment determination unit determines a correspondence relationship between the vehicle and the remote control unit based on the analyzed state information.

摘要： An acquisition unit (210) acquires sensor information and crew member identification information from a crew member terminal (10). A detection unit (220) detects an improvement-requiring item by processing the sensor information. The improvement-requiring item is an item that needs to be improved by the crew member. A selection unit (230) selects a transmission destination of caution information by using information on the improvement-requiring item. For example, the selection unit (230) selects the transmission destination, for example, by using a type of the detected improvement-requiring item. A transmission unit (240) transmits the caution information to the transmission destination selected by the selection unit (230). The caution information is information indicating that the improvement-requiring item is detected.

摘要： A vehicle control unit controls automated driving of a target vehicle on the basis of first information obtained by a sensor of the target vehicle. An analysis unit analyzes state information of the target vehicle on the basis of the first information obtained by the sensor of the target vehicle, and second information obtained by a sensor outside the target vehicle. A specification unit specifies a control policy of the target vehicle on the basis of the analyzed state information.

摘要： A video reception unit obtains a first video and a second video that are different in an imaging position from each other. An important video determination unit determines a video having a higher degree of importance on the basis of the first video and the second video. A video adjustment report unit transmits a transmission video adjustment report that is used to adjust qualities of the first video and the second video in accordance with a result of determining a degree of importance. A first video adjustment unit adjusts the first video on the basis of the transmission video adjustment report. A second video adjustment unit adjusts the second video on the basis of the transmission video adjustment report.

摘要： An image reception unit receives an internal image from a mobile object. An accident risk prediction unit predicts a risk of occurrence of an accident inside the mobile object based on the internal image and situation information indicating a situation of the mobile object. A quality determination unit determines internal image quality information indicating quality of the internal image based on a result of the predicted risk of the inside accident. A quality adjustment unit adjusts the quality of the internal image based on the internal image quality information.

摘要： In order to solve the noise problem occurring in a switching power supply, provided is a power supply device having: a plurality of switching power supplies (POW1-n) that receive supply of electric power from a common primary side power supply (Vin); and a control unit (140) for controlling operations of the switching power supplies (POW1-n). The control unit (140) inputs control signals (St1-n) to the respective switching power supplies (POW1-n), the control signals (St1-n) indicating the timings of turning on switching elements. The switching power supplies (POW1-n) turn on the switching elements at timings in accordance with the control signals (St1-n) and draw current from the primary side power supply (Vin). A first control signal (St1) input to a first switching power supply (POW1) and a second control signal (St2) input to a second switching power supply (POW2) are adjusted so that the switching element of the first switching power supply (POW1) and the switching element of the second switching power supply (POW2) are not switched from OFF to ON at same timing.

摘要： An image reception unit receives an image from a vehicle through a network. An event prediction unit predicts an event based on the image received by the image reception unit. Based on an event result predicted by the event prediction unit an important area identification unit identifies an area related to the predicted event as an important area in the image. An image adjustment unit adjusts image quality concerning the important area, which is identified by the important area identification unit, in the image.
