The gate ECU is installed at a position outside the battery pack and relays communication between the battery ECU and the HVECU.

Vehicle

A hybrid vehicle includes: an engine; a battery; a power converter; a relay; a first controller; and a second controller. The second controller is configured to control the engine and the power converter according to allowable charging power and allowable discharging power received from the first controller. The second controller has, as control modes, a normal mode in which the relay is closed and the battery and the power converter are electrically connected and a batteryless drive mode in which the relay is opened to cause the hybrid vehicle to move with the battery electrically disconnected from the power converter. The second controller is configured to select the batteryless drive mode when at least one of the magnitude of the allowable charging power and the magnitude of the allowable discharging power become smaller than a first predetermined value.

Power control system, electric powered vehicle, and power control method

When a traveling state of a vehicle is switched, the vehicle requests delivery of an update program from an OTA server. For example, when the vehicle travels with an occupant on board, the vehicle requests delivery of an update program for manned vehicle traveling from the OTA server. When the vehicle travels with an occupant not on board, the vehicle requests delivery of an update program for unmanned vehicle traveling from the OTA server. When the OTA server receives the request for delivery of the update program for manned vehicle traveling/unmanned vehicle traveling, the OTA server delivers the requested update program for manned vehicle traveling/unmanned vehicle traveling to the vehicle. The vehicle updates a diagnosis program using the received update program for manned vehicle traveling/unmanned vehicle traveling.

When a diagnostic period of a specific failure arrives, a management center transmits, to a vehicle, an instruction to order execution of a failure diagnosis of the specific failure. When an ECU of the vehicle receives the instruction to order execution of the failure diagnosis from the management center, the ECU of the vehicle determines whether or not the failure diagnosis can be executed. When the failure diagnosis cannot be executed, the ECU causes the vehicle to continue traveling without executing the failure diagnosis, and ends a process. In this case, the ECU postpones the failure diagnosis in the current diagnostic period, and executes the failure diagnosis when a next diagnostic period arrives. When the ECU determines that the failure diagnosis can be executed, the ECU executes the failure diagnosis.

Controller for vehicle

A vehicle includes a battery pack including a secondary battery and a first control device, a second control device provided separately from the battery pack, and a converter. The converter is configured to select a conversion formula from options depending on a situation and use the selected conversion formula to convert at least one of a first current upper limit value and a second current upper limit value into at least one of a first power upper limit value and a second power upper limit value.

Vehicle, vehicle control system, vehicle control method

When a device temperature (Tb) of an electrical storage device () is higher than or equal to a reference temperature, a fan () is driven at an air quantity larger than or equal to a reference air quantity. On the other hand, when the device temperature is lower than the reference temperature, air that has received heat from the electrical storage device is guided to a discharge chamber by driving the fan at an air quantity smaller than the reference air quantity on the basis of the fact that an air-conditioning system is operating and an outside air temperature is lower than or equal to a predetermined temperature. When the air-conditioning system is operating and the outside air temperature is lower than or equal to the predetermined temperature, it is assumed that there is a temperature difference between a passenger compartment and the discharge chamber. At this time, by driving the fan at the air quantity smaller than the reference air quantity, it is possible to bring the temperature of the discharge chamber close to the temperature of the passenger compartment by raising the temperature of the discharge chamber, so it is possible to reduce the temperature difference between the discharge chamber and the passenger compartment.

Vehicle comprising an electrical storage device cooled by a fan

A temperature regulation system includes: an electric storage device, installed in a vehicle and configured to perform charge and discharge; an intake duct that leads air of a vehicle interior to the electric storage device; a fan configured to cause the air to be taken into the intake duct; a filter that is provided inside the intake duct and that prevents passage of foreign matter; and a controller that estimates a clogging amount of the foreign matter on the filter. The controller is configured to increase the estimated clogging amount as there increases a total amount of the air that is supplied to the electric storage device accompanying driving of the fan, and the number of times that the vehicle is brought to a state in which air is allowed to flow into and flow out of the vehicle.
