IN-VEHICLE CONTROLLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240132045 titled 'IN-VEHICLE CONTROLLER

Simplified Explanation

The in-vehicle controller described in the patent application is a system installed in a vehicle that includes an engine, a motor connected to the engine's crankshaft, a high voltage battery connected to the motor, a low voltage battery, a dc/dc converter, and a relay. The controller stops driving the dc/dc converter after the motor is turned off by disconnecting the high voltage battery with the relay.

• The in-vehicle controller is installed in a vehicle with an engine and a motor capable of generating electricity.
• The motor is connected to the engine's crankshaft.
• A high voltage battery is connected to the motor via a high voltage power line.
• A low voltage battery is also present in the system.
• A dc/dc converter is connected to both the high voltage power line and a low voltage power line.
• A relay is attached to the high voltage battery side of the high voltage power line from the dc/dc converter.

Potential Applications
