Abstract: The disclosure provides an assisting device control system capable of appropriately fixing a brace to the body of a wearer. A control system S includes: a waist sensor 10f, a right leg sensor 14f, and a left leg sensor 14g detecting a tension factor when a brace is worn; a tension recognition part 25 recognizing a tension from the tension factor; and a driving control part 26 controlling the driving of an assisting device 1. The driving control part 26 permits the driving of the assisting device 1 if the recognized tension is within a permission range, which has a predetermined lower limit value and a predetermined upper limit value.

Abstract: A battery control apparatus for an electric vehicle includes a processor. The processor controls a charging and discharging device of the electric vehicle that includes a battery storing electric power for traveling, a power transmitter performing electric power transmission between the power transmitter and charging equipment provided outside the electric vehicle, and the charging and discharging device charging and discharging the battery via the power transmitter. The processor causes the battery to discharge to the charging equipment via the power transmitter until a voltage of the battery reaches a discharge end voltage corresponding to a state of charge (SOC) of 0%, and thereafter causes the battery to be charged until the voltage of the battery reaches a charge end voltage corresponding to the SOC of 100%. The processor creates a characteristic map representing a relation between the SOC of the battery and the voltage of the battery.

Abstract: A battery pack monitoring device includes a battery pack, at least one first wireless communicator, at least one second wireless communicator, and a control device. The battery pack is installed in a vehicle and includes a battery. The at least one first wireless communicator is disposed inside the battery pack and can perform wireless communication. The at least one second wireless communicator is disposed in the vehicle outside the battery pack and can perform wireless communication. The control device includes one or more processors, and one or more memories. The one or more processors are configured to execute a process including trying the wireless communication between the first wireless communicator and the second wireless communicator, and estimating the presence and/or absence of a damage to the battery pack based on an establishment state of the wireless communication between the first wireless communicator and the second wireless communicator.

Abstract: A conversation device that has conversation with a user of an electric wheelchair traveling in a facility in which a plurality of beacon transmitters are disposed includes: a conversation processing part that has conversation with the user using a prediction model; a conversation registration part that stores the conversation as a history; and a model generation part that generates the prediction model through learning, in which in the history of the conversation, a situation of the conversation at a time point when the conversation is made, details of the conversation, and a user's satisfaction with the conversation are associated, the situation of the conversation includes information with which the beacon transmitter that has received radio waves during the conversation is able to be identified, and the model generation part learns the prediction model again at a predetermined timing by classifying the history of the conversation.

Abstract: A door device of a small-sized vehicle, that enables easily interlocking a door lock and a lever is provided. An openable door 70 is provided to a side of a body, a lever 92 provided inside the door 70 for opening the door 70 is swingably provided, and a rotational central axis of a lever supporting shaft 120 turned by a swing of the lever 92 and a rotational central axis of a latch for a door lock (a lever member 144) driven by a turn of the supporting shaft 120 are made the same.

Abstract: A battery unit that prevents an expansion of a battery cell, and that can prevent an increase in size of the battery unit or an increase in the number of components. The battery unit includes a box-like battery case that accommodates therein a battery module having a generally rectangular solid shape and including plural sheet-like battery cells stacked flat in a vertical direction of a vehicle body. The battery unit includes: a bottomed box-like casing body that forms a part of the battery case and into which the battery module is accommodated from above the vehicle body; and a fixing plate that abuts on a top surface of the battery module. The battery module is fixed to the casing body with pressure being applied to the battery module from above the vehicle body, by fastening the fixing plate to the casing body.

Abstract: An electric vehicle can include a pair of left and right rear wheels configured to be driven by the rotary driving power of a motor supplied with electric power from a battery. A rear body can support the motor and rear wheels, and is attached at the back of a body frame. A battery box houses at least the battery, and is supported by a battery box supporting frame joined to the body frame below a seat of the vehicle. A monitoring board monitors the state of the battery, and can be located on top of the battery. A BMU collects information from the monitoring board, and a contactor opens and closes the connection between the battery and a drive circuit for the motor. The BMU and the contactor are housed in the battery box and in front of the battery.
