IN-VEHICLE CONTROLLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18383675 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 for generating electricity, a high voltage battery connected to the motor, a low voltage battery, a DC/DC converter connected to both the high voltage and low voltage power lines, 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 the motor is turned off by disconnecting the high voltage battery with the relay turned off, completing batteryless driving.
- The in-vehicle controller is installed in a vehicle with an engine and a motor capable of generating electricity.
- The system includes a high voltage battery, a low voltage battery, a DC/DC converter, and a relay for managing power distribution.
- The controller stops driving the DC/DC converter after batteryless driving by disconnecting the high voltage battery with the relay turned off.
