A vehicle control device mounted on a vehicle includes: an operation detection unit that detects an operation performed on the vehicle by a user; a power supply control unit that controls execution of power supply from a first battery involved in vehicle traveling to an auxiliary load powered by a second battery that is different from the first battery, with a start switch of the vehicle being off; and a prohibition control unit that prohibits the power supply to the auxiliary load by the power supply control unit, in response to the operation of the user detected by the operation detection unit.

Vehicle control device, method, program, and vehicle

A battery cell short circuit detection device includes: a control unit that controls operation of a direct current-direct current converter; a first acquisition unit that acquires a storage rate of the battery; a second acquisition unit that acquires a current flowing into the battery and a current flowing out of the battery when the direct current-direct current converter is operating; a third acquisition unit that acquires a terminal voltage value that is a voltage that appears at a terminal of the battery when the direct current-direct current converter is not operating; and a determination unit that determines presence or absence of the short circuit between the battery cells based on an average storage rate indicating an average value of the storage rate of the battery, an average inflow current value indicating an average value of the current flowing into the battery, and the terminal voltage value.

Battery cell short circuit detection device, method, and storage medium

A vehicle control device for a vehicle includes a processor. The vehicle includes a first battery, a second battery, an auxiliary load powered by the second battery, and a DC-to-DC converter configured to supply electric power from the first battery to either the second battery or the auxiliary load, or to both of the second battery or the auxiliary load. The processor is configured to: determine the state of a start switch and the boarding state of the vehicle; acquire the voltage of the second battery; and when the processor determines that the vehicle is in a non-started on-board state, determine based on the voltage of the second battery an order in which the DC-to-DC converter and the auxiliary load are driven. The non-started on-board state is a state in which the start switch is off and a user is presumed to be in the vehicle.

Vehicle control device, control method, non-transitory storage medium, and vehicle

A vehicle control apparatus mounted on a vehicle including a DC-DC converter that supplies electric power from a first battery to a second battery and an auxiliary load includes an electronic control unit configured to control an operation of the converter, determine a state of a starter switch of the vehicle, detect a user operation to the vehicle, and acquire charging status information of the second battery. The electronic control unit is configured to, when the electronic control unit detects a first operation by the user and determines that the starter switch is off, drive the converter such that the converter charges the second battery, and, when an electric power amount charged in the second battery reaches a target amount of charge set based on an amount of electric power to be consumed by the auxiliary load while the starter switch is off, stop the converter.

Vehicle control apparatus, control method, non-transitory storage medium, and vehicle

An apparatus for positioning a part of a body secured to a mount in a vehicle body assembly line is provided wherein a swingable platform is supported for swing motion at one end of a slide base which is moved back and forth by programmable high precision positioning mechanism, such as servo or pulse motor, and a jig pallet designed for a particular vehicle model and having a locator for locating and holding the part in a predeterined attitude is removably engaged by clamps at a free end of the platform, whereby the platform having the jig pallet clamped thereto is rotated such that the part held by the pallet may take an assembly attitude and the slide base is moved to transfer the part to a position for assembly to the body.
