IN-VEHICLE CONTROLLER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240227770 titled 'IN-VEHICLE CONTROLLER

The in-vehicle controller described in the patent application is a component installed in a vehicle alongside an engine, a motor that can generate electricity connected to the engine's crankshaft, a high voltage battery connected to the motor via a high voltage power line, a low voltage battery, a dc/dc converter linked to both the high voltage power line and a low voltage power line connected to the low voltage battery, and a relay attached to the high voltage battery side of the high voltage power line from the dc/dc converter. The controller stops driving the dc/dc converter after powering off the motor when completing batteryless driving by disconnecting the high voltage battery with the relay turned off.

• The in-vehicle controller is installed in a vehicle and works in conjunction with various components such as an engine, a motor, high voltage and low voltage batteries, a dc/dc converter, and a relay.
• The controller is designed to stop the dc/dc converter's operation once the batteryless driving mode is completed by disconnecting the high voltage battery using the relay.
• This innovation aims to optimize energy usage and improve the overall efficiency of the vehicle's power system.
• By effectively managing the power flow between the different components, the controller helps enhance the vehicle's performance and reduce energy wastage.
• The technology ensures a seamless transition between different driving modes, ultimately leading to a more sustainable and eco-friendly driving experience.
