摘要： A steer-by-wire steering system includes: a steering device including a steering motor powered by a main power source and/or a backup power source; and a controller configured to control the steering device based on a steering request. When the backup power source is normal, the controller executes an abnormal-situation control based on electric power supplied to the steering motor by the main power source and/or the backup power source when the controller determines that the voltage of the main power source is less than a first threshold. When the backup power source is abnormal, the controller executes the abnormal-situation control based on electric power supplied to the steering motor by the main power source when the controller determines that the voltage of the main power source is less than a second threshold that is greater than the first threshold.

摘要： An information processing device calculates a quoted price to be presented to a purchase contemplation person for a vehicle. The information processing device includes a control unit that calculates a demand forecast when the purchase contemplation person uses the vehicle as a car-sharing vehicle, calculates an expected income when the purchase contemplation person uses the vehicle as the car-sharing vehicle, based on the demand forecast, and calculates the quoted price based on a vehicle price of the vehicle and the expected income, to present the quoted price to the purchase contemplation person.

摘要： A power supply system includes a system control unit, an auxiliary power supply, and an auxiliary-power-supply control unit. The system control unit and the auxiliary-power-supply control unit are configured such that information of at least one control unit of the system control unit and the auxiliary-power-supply control unit is able to be output to another control unit of the system control unit and the auxiliary-power-supply control unit. The at least one control unit is configured to output information indicating that an operation of the at least one control unit is stopped to the other control unit when the at least one control unit stops the operation of the at least one control unit.

摘要： An electric power source device includes an auxiliary electric power source for a main electric power source that supplies electric power to electric power supply targets, including an electric circuit of a control system for controlling a specific control target and an electric circuit of a power system that requires larger electric power than the electric circuit of the control system; and a selection circuit configured to supply the electric power from one electric power source having a higher voltage, out of the main electric power source and the auxiliary electric power source, to at least the electric circuit of the control system among the electric power supply targets.

摘要： An auxiliary power source device includes a main power source-side path, an auxiliary power source-side path, a power source control circuit, an analog determination circuit that is provided separately from the power source control circuit, and a power source switching circuit. The power source control circuit controls switching between a conduction state and an interruption state on the main power source-side path and the auxiliary power source-side path. The analog determination circuit determines an occurrence of abnormality in the main power source and generates a switching signal when the occurrence of the abnormality in the main power source is determined. The power source switching circuit switchs a power source for supplying power to a power supply target, from the main power source to the auxiliary power source.
