control device

Abstract

The purpose is to enable stable power supply to external devices. [Solution] The control unit of a vehicle control system equipped with a battery capable of supplying power to multiple in-vehicle devices and external devices, and an engine capable of supplying power to the battery, starts charging the battery with the engine when the remaining charge of the battery, while supplying power to an external device, falls below a first threshold. Then, while charging the battery, the control unit of the control system restricts the power supply from the battery to one or more restricted devices included in the multiple in-vehicle devices when the remaining charge of the battery falls below a second threshold, which is less than the first threshold.

Claims

1. A control device for a vehicle equipped with a battery capable of supplying power to multiple in-vehicle devices and external devices, and an engine capable of supplying power to the battery, When the remaining charge of the battery while supplying power to the external device falls below a first threshold, the engine starts charging the battery. If the remaining charge of the battery falls below the second threshold, which is less than the first threshold, during charging of the battery, the power supply from the battery to one or more restricted devices included in the plurality of in-vehicle devices will be restricted. A control unit configured to perform the following actions: Control device.

2. Multiple power supply limitation options are defined for the aforementioned multiple in-vehicle devices. The aforementioned multiple restriction candidates have a predetermined priority order for power supply restrictions. The control unit, To determine one or more restricted devices from the plurality of restricted candidates according to the aforementioned priority, It is configured to perform further actions. The control device according to claim 1.

3. Restricting the power supply by the battery to the one or more restricted devices means that The amount of power supplied to one or more restricted devices is limited according to the difference between the power consumption of the battery and the amount of charge the battery is supplied by the engine, and the power consumption of the multiple restricted devices. including, The control device according to claim 2.

4. Restricting the power supply by the battery to the one or more restricted devices includes cutting off the power supply to the one or more restricted devices. The control device according to claim 1 or 2.

5. The control unit, when the output for charging the battery by the engine is at its maximum, restricts the power supply from the battery to the one or more restricted devices. The control device according to any one of claims 1 to 3.
