Abstract: A vehicle includes: an instrument panel that displays an alarm to a driver; and an ECU that controls the instrument panel based on a setting as to whether the driver is to perform maintenance of the vehicle or not. In a first setting in which the driver is to perform maintenance, the ECU controls the instrument panel to display an alarm when a failure occurs in an on-vehicle device. In a second setting in which the driver is not to perform maintenance, the ECU controls the instrument panel not to display an alarm about a failure less influencing traveling.

Abstract: A server includes a storage device that stores history information indicating a history of a state of a vehicle, and a controller that performs a process using the history information. The controller makes a first determination of whether or not a vehicle load exceeds a first load. For the vehicle for which it has been determined that the vehicle load is higher than the first load in the first determination, the controller makes a second determination of whether or not an environmental load is higher than a second load. When it is determined that the environmental load is higher than the second load in the second determination, the controller outputs an area change request requesting a change of the dispatch area of the vehicle to another dispatch area lower in the environmental load than a current dispatch area.

Abstract: A vehicle comprises a motor configured to output a power for driving; a power storage device configured to supply electric power to the motor; a main relay provided between the motor and the power storage device; a power receiving connector configured to be connectable with a power feed connector of an external charger; and a charging relay connected with the power receiving connector and connected with the power storage device via the main relay. This vehicle further comprises a control device configured to determine whether electric power from the external charger is supplied to the power receiving connector during charging of the power storage device with the electric power from the external charger in closed positions of the main relay and the charging relay and to open the main relay when it is determined that the electric power from the external charger is not supplied to the power receiving connector.

Abstract: When such an abnormality that a battery voltage system voltage is brought into an overvoltage state during regenerative control of a motor occurs, a booster converter is shut down, a system main relay is brought into a non-arc state and turned off. Then, an engine is started when an operation of the engine is stopped. The booster converter is used to determine turning-off of the system main relay, and a battery-less travel is started thereafter. In this way, inconvenience that possibly occurs by starting the battery-less travel at a time when abnormality of the system main relay being stuck to be on occurs can be avoided.

Abstract: In motor double-drive mode, a first rotation speed and a second rotation speed as a drive shaft rotation speed are calculated from rotation speeds of motors on the assumption that an engine rotation speed is zero. A state where a difference between the first rotation speed and the second rotation speed is larger than a threshold continues, and, when a malfunction counter becomes larger than a threshold, it is determined that there is a malfunction in a one-way clutch or pinion gears. At a start of the engine, it is determined that there is a malfunction in the one-way clutch when the engine rotation speed is normally increasing, and it is determined that there is a malfunction in the pinion gears when the engine rotation speed is not normally increasing.

Abstract: When a vehicle collision is detected, a electric connection between a power supply and an input stage of an inverter is switched to the disconnected condition. Then, when a rotation speed of an alternating current motor is higher than an allowable rotation speed or a terminal voltage of a storage unit provided at the input stage is higher than an allowable terminal voltage, an exciting current command value is set at a value other than zero and a torque current command value is set at zero, and when the rotation speed is equal to or lower than the allowable rotation speed and the terminal voltage is equal to or lower than the allowable terminal voltage, both command values are set at zero. An exciting current component and a torque current component of an alternating current supplied from the inverter to the motor are controlled according to the set command values.
