Patents by Inventor PRASHANT MER

PRASHANT MER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10005339
    Abstract: A thermal management system includes a coolant pump, high-voltage electric heater (HEH) for heating the coolant, a heater core, a blower directing air to the heater core, a cabin heater valve (CHV), sensors, and a controller. The CHV has an Engine Bypass position blocking coolant flow from the HEH into the engine, and an Engine Link position directing coolant from the HEH into the engine. In a method, the sensors measure engine outlet coolant temperature (ECT), inlet coolant temperature (ICT) to the HEH, inlet air temperature into the heater core, and outlet air temperature from the heater core. The controller calculates a target coolant temperature (TCT) value as a function of the air temperatures and mass flow rates, and controls the CHV via position control signals such that the CHV is switched between the Engine Link position and the Engine Bypass position when ICT equals the calculated TCT value.

  • Patent number: 9676248
    Abstract: Vehicles and methods for controlling climate control systems may include, but are not limited to at least one seat, a climate control system, and a controller communicatively coupled to the climate control system, wherein the controller is configured to calculate a directional sun effect for each of the at least one seats, and modify at least one of an airflow, a temperature and air distribution of the climate control system based upon the calculated directional sun effect for each of the at least one seats.
