A mobile body control device that includes a mobile terminal position measurement unit configured to: communication between a first communication unit and a mobile terminal is intermittently performed, to start mobile terminal position measurement processing for measuring the position of the mobile terminal based on a communication state between the first communication unit and the mobile terminal; and, when the position of the mobile terminal measured by the mobile terminal position measurement processing does not reach a second prescribed distance or less from a mobile body within a prescribed time from a point of start of the mobile terminal position measurement processing, the switching period is changed to a second measurement period that is longer than the first measurement period and the mobile terminal position measurement processing is continued.

An electric wire protection device includes a voltage adjusting unit that adjusts voltage of a power source side and supplies the resulting voltage to a load, and a controller that includes a calculation unit configured to compute temperature information of an electric wire connecting the power source and the load from a value of an electric current flowing through the voltage adjusting unit, and that is configured to make the voltage adjusting unit into a shutoff state of shutting off the power source and the load on the basis of the temperature information.

Electric wire protection device and control method for electric wire protection device

An electric wire protection device includes a voltage adjuster that adjusts voltage on a power source side to be supplied to a load and a controller that includes a temperature calculation part which calculates temperature information of an electric wire based on a current value flowing through the voltage adjuster. The controller sets a first time constant as a time constant used to calculate the temperature information while the voltage adjuster is in the interrupted state, and sets a second time constant as a time constant used to calculate the temperature information while the voltage adjuster supplies power to the load. The first time constant is a value larger than the second time constant and equal to or larger than an actual time constant of the electric wire, and the second time constant is a value smaller than the actual time constant of the electric wire.

Electric wire protection device

An electric-wire protection device includes a voltage adjustment unit that adjusts the voltage to a load, and a controller that includes a temperature calculation unit that calculates temperature information on an electric wire from a value of current, and makes the voltage adjustment unit into a shut-off state based on the temperature information. The temperature information is calculated from an amount of temperature changes based on the current value and a predetermined initial value. The controller shifts into a sleep state when a sleep condition is satisfied that includes a condition that the temperature information is lower than the initial value. The initial value when the controller returns from the sleep state is based on a convergence value of temperature in conducting energization on the electric wire at a maximum value of steady-state current.
