Method for Controlling Vehicle Thermal Management System - A simplified explanation of the abstract

This abstract first appeared for US patent application 17813399 titled 'Method for Controlling Vehicle Thermal Management System

Simplified Explanation

The abstract describes a method for controlling a vehicle's thermal management system. Here is a simplified explanation:

  • The method determines a target temperature for the evaporator, which is a component of the vehicle's cooling system.
  • This target temperature is calculated by subtracting a predetermined temperature from the measured temperature of the evaporator.
  • This calculation is performed when the vehicle is only cooling the passenger compartment and the measured temperature of the inverter (another component) exceeds a certain threshold temperature.
  • The method then adjusts the RPM (revolutions per minute) of the compressor, which is responsible for circulating the refrigerant in the cooling system.
  • The adjustment of the compressor's RPM is done in response to the determined target temperature of the evaporator.

Potential applications of this technology:

  • Automotive industry: This method can be applied in vehicles to optimize the cooling system's performance and efficiency.
  • Electric vehicles: The method can be particularly useful in electric vehicles where thermal management is crucial for maintaining optimal performance and battery life.

Problems solved by this technology:

  • Inefficient cooling: By adjusting the compressor's RPM based on the target temperature, the method ensures that the cooling system operates at the appropriate level to maintain the desired temperature in the passenger compartment.
  • Overheating of the inverter: The method prevents the inverter from reaching a temperature that could potentially cause damage or affect its performance.

Benefits of this technology:

  • Improved energy efficiency: By adjusting the compressor's RPM based on the target temperature, the method optimizes the cooling system's operation, reducing energy consumption.
  • Enhanced passenger comfort: The method ensures that the desired temperature in the passenger compartment is maintained, providing a comfortable environment for occupants.
  • Protection of components: By preventing the inverter from overheating, the method helps protect the vehicle's electrical components, ensuring their longevity and reliability.


Original Abstract Submitted

An embodiment method for controlling a vehicle thermal management system includes determining a target temperature of an evaporator by subtracting a predetermined temperature from a measured temperature of the evaporator, in a case in which only interior cooling of a passenger compartment is performed and a measured temperature of an inverter is higher than a threshold temperature, and adjusting an RPM of a compressor in response to the determined target temperature of the evaporator.
