An operating mode control device includes a travel driving force information acquisition unit configured to acquire a time-series travel driving force when traveling on a travel route; a vehicle speed information acquisition unit configured to acquire a time-series vehicle speed when traveling on the travel route; a motor operation estimation unit configured to estimate a time-series torque and rotation speed of the motor on the basis of a time-series travel driving force and vehicle speed; an efficiency calculation unit configured to acquire a time-series efficiency value of each operating mode on the basis of the time-series torque and rotation speed and calculate a total efficiency value; an operating mode determination unit configured to determine the operating mode having the highest total efficiency value as a default operating mode; and an operation control unit configured to control an operation by the default operating mode.

Control device for determining an operating mode defining a number of motors operating in an electric vehicle

A state determination unit determines whether a state of traveling performance of a fuel cell vehicle is a normal performance state, a limited performance state, or a low performance state. When the state determination unit determines that the fuel cell vehicle is in the normal performance state or the limited performance state, a traveling propriety determination unit determines that the fuel cell vehicle can travel. A notification control unit performs a limited state notification when the state determination unit determines that the fuel cell vehicle is in the limited performance state and the traveling propriety determination unit determines that the fuel cell vehicle can travel.

Traveling propriety determination device

A battery management device includes: a first switch state acquisition unit configured to acquire the state of an ignition switch; a determination unit configured to determine to perform correction control for correcting an error in the state of charge (SOC) of the battery when the ignition switch is operated from ON to OFF; a correction control unit configured to perform the correction control of the SOC of the battery when it is determined that the correction control is to be performed; and a second switch state acquisition unit configured to acquire the state of a cancel switch for canceling the execution of the correction control. When the ignition switch is operated from ON to OFF while the cancel switch is ON, the determination unit determines that the correction control is not to be performed.
