ENGINE IDLE SPEED LOGIC SYSTEMS AND METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18069834 titled 'ENGINE IDLE SPEED LOGIC SYSTEMS AND METHODS

Simplified Explanation: The patent application describes systems and methods for controlling engine idle speed based on electrical load. A logic device is used to determine battery state of charge, alternator output, and load to adjust engine idle speed accordingly.

• The system uses a logic device to control engine idle speed based on electrical load.
• The logic device determines battery state of charge, alternator output, and load to make adjustments.
• Idle speed is increased if the battery state of charge is low and the load exceeds the alternator output.
• Idle speed is decreased if the battery state of charge is below a certain threshold.

Potential Applications: This technology can be applied in automotive systems to optimize engine performance and fuel efficiency based on electrical load requirements.

Problems Solved: This technology addresses the challenge of efficiently managing engine idle speed in response to varying electrical loads in a vehicle.

Benefits: The benefits of this technology include improved fuel efficiency, optimized engine performance, and enhanced battery management in vehicles.

Commercial Applications: Title: Engine Idle Speed Control System for Automotive Applications This technology can be commercially used in the automotive industry to enhance vehicle performance, fuel efficiency, and battery management systems.

Prior Art: Prior art related to this technology may include patents or research on engine idle speed control systems in vehicles.

Frequently Updated Research: Researchers may be conducting studies on the impact of engine idle speed control systems on overall vehicle performance and fuel efficiency.

Questions about Engine Idle Speed Control Systems: 1. How does this technology improve fuel efficiency in vehicles? 2. What are the key factors considered by the logic device to adjust engine idle speed based on electrical load?

Original Abstract Submitted

Systems and methods for controlling engine idle speed based on electrical load are provided. A system includes a logic device configured to perform various operations for controlling an idle speed of an engine. The logic device is configured to determine a state of charge (SOC) of a battery, a maximum output of an alternator at a current idle speed of an engine, and a load on the alternator. The logic device is further configured to initiate an increased idle speed of the engine based on the determined SOC of the battery and based on the load being greater than the maximum output. The logic device is further configured to initiate a decreased idle speed of the engine based on the SOC being less than an SOC threshold. Associated methods are also provided.
