Abstract: An electric-brake controller controls an electric brake operable by an electric motor. The electric-brake controller includes: a rotation-angle obtainer including (i) a relative-rotation-angle obtaining unit that obtains a relative rotation angle of the electric motor for a set time, based on values output and received from a rotation-angle sensor at intervals of the set time, and (ii) an absolute-rotation-angle obtaining unit that calculates the obtained relative rotation angle with consideration of an orientation of the relative rotation angle to obtain an absolute rotation angle that is a rotation angle of the electric motor from a start of its operation; a recognition-error detector that detects a recognition error in the rotation-angle obtainer based on the obtained absolute rotation angle or a changing state of the absolute rotation angle; and a motor controller that controls the electric motor based on a result of detection performed by the recognition-error detector.

Abstract: When a vehicle is in an accelerator off state and satisfies a free-run condition, a regeneration control unit performs free-run control on the vehicle so that the amount of regenerative electric power is decreased. The regeneration control unit sets a free-run prohibited zone between a starting point of a regeneration enhancement zone and a position that is located in front of and separated by a determination distance from the starting point.

Abstract: When it is judged that a downward slope segment exists in a scheduled traveling route, the control device of a hybrid vehicle sets a target remaining capacity SOC* in a pre-use segment in a downward slope segment and the downward slope segment to a “low-side remaining capacity Sd which is ΔSd smaller than a standard remaining capacity Sn” (step S105). Furthermore, when it is presumed that a rise amount of a remaining capacity by an extended regeneration control is large in the pre-use segment and the downward slope segment (refer to a judgment as “Yes” in step S104), the target remaining capacity SOC* is set to a “low-side remaining capacity Sd which is a sum of ΔSd and ΔS1 smaller than the standard remaining capacity Sn” (step S106).

Abstract: An electric power source system includes an electric power generator, a voltage conversion device, a battery, an electrical load, and a control device. The voltage conversion device converts a direct current voltage. The battery is electrically connected to the electric power generator through the voltage conversion device. The electrical load is electrically connected to the electric power generator in a parallel relationship with the battery without passing through the voltage conversion device. The control device is configured to charge the battery through the voltage conversion device based on regenerative electric power in a regenerative state in which the regenerative electric power is generated by the electric power generator. the control device is configured to increase an electric power consumption of the electrical load further when the control device detects an event that impedes the charging in the regenerative state than when the control device does not detect the event.
