摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
