Abstract: A vehicle management apparatus is configured to manage a vehicle for delivery loaded with one or more packages. The vehicle management apparatus includes a controller configured to, upon detecting that the vehicle has stopped, determine, based on vehicle data indicating a status of the vehicle, whether a driver of the vehicle is making a delivery, and control a door of the vehicle to lock in a case in which it has been determined that the driver is making a delivery.

Abstract: An information processing apparatus includes a controller configured to extract roads that are difficult for a particular truck to travel based on a travel history of one or more trucks and generate route guidance such that roads that are easy for the particular truck to travel are given priority by avoiding at least one road among the extracted roads.

Abstract: A delivery support apparatus according to the present disclosure includes a controller configured to acquire information about a vehicle used for delivery of a package, the information having been acquired on the vehicle, determine, based on the information about the vehicle, a loading/unloading location at which the package was loaded or unloaded, and generate, based on the loading/unloading location, information about a location at which packages can be loaded/unloaded.

Abstract: A motor includes a rotating shaft, an armature core, a plurality of coils, a commutator and a pair of brushes. The plurality of coils include three or more coil pairs each of which consists of a pair of coils configured to be point-symmetrical with respect to a rotation center axis. One of the three or more coil pairs constitutes a pair of number-of-turns adjustment coils which would have a lowest inductance in the plurality of coils if all the plurality of coils had the same number of turns. The number of turns of the pair of number-of-turns adjustment coils is set to be larger than the number of turns of any of the remainder of the three or more coil pairs. The inductance of the pair of number-of-turns adjustment coils is set to be higher than the inductance of any of the remainder of the three or more coil pairs.

Abstract: A DC motor is configured so that, while either one of a pair of power feeding brushes makes contact with two commutator segments, the other makes contact with only one of two commutator segments. The DC motor is further provided with: a plurality of coils; a filter unit; and a calculation unit. The number of turns of a predetermined coil among the plurality of coils is different from the numbers of turns of the other coils. The filter unit allows the passing of the waveform of current generated on the basis of the fact that the numbers of turns are different from each other, and interrupts the waveform of current generated at the switching of the states of the contacts of the power feeding brushes to the commutator segments. The calculation unit calculates a rotational speed from the waveform passed through the filter unit.

Abstract: This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.
