Publication number: 20230123367Abstract: A vehicle air control system includes a vehicle body that defines an interior. A first particulate matter sensor is coupled to an exterior of the vehicle body. A second particulate matter sensor is disposed within the interior of the vehicle body. A temperature sensor is coupled to the exterior of the vehicle body. A vehicle speed sensor is coupled to the vehicle body. A heat, ventilation, and air condition (HVAC) system is disposed within the interior of the vehicle body. The HVAC system includes an inlet door rotatable between a first position, a second position, and a third position therebetween. A controller is configured to receive a signal from at least one of the first and second particulate matter sensors, the temperature sensors, and the vehicle speed sensor. The controller is configured to rotate the inlet door in response to the signal.Type: ApplicationFiled: December 20, 2022Publication date: April 20, 2023Applicant: Ford Global Technologies, LLCInventors: Alan Gutowski, David Alan Wong

Patent number: 10427494Abstract: A method for controlling a vehicle climate control system includes steps of determining that a first predetermined set of conditions are satisfied whereby a heating, ventilation, and air-conditioning (HVAC) system airflow into a passenger cabin will exceed a predetermined HVAC airflow temperature threshold and, if so, automatically implementing a first climate control system operating condition at least reducing the HVAC airflow into the passenger cabin. On determining that a second predetermined set of conditions are satisfied whereby the HVAC airflow into the passenger cabin will satisfy the predetermined HVAC airflow temperature threshold, the method includes a step of automatically implementing a second climate control system operating condition increasing the HVAC airflow into the passenger cabin. Climate control systems for implementing the described methods are provided.Type: GrantFiled: May 3, 2017Date of Patent: October 1, 2019Assignee: Ford Global Technologies LLCInventors: David Alan Wong, Debasish Dhar, Alan Gutowski, Alan Douglas Wallington, Manfred Koberstein, Mark G.

Patent number: 9182166Abstract: A climate controller device may be configured to perform operations including comparing an outside air temperature to a threshold temperature; selecting, based on the comparison, one of a function to determine target compressor off setpoint values for relatively lower temperatures and a function to determine target compressor off setpoint values for relatively higher temperatures; retrieving a value according to the selection function to determine target compressor off setpoint values, the value specifying a compressor off setpoint value corresponding to airflow configuration settings; and determining a target compressor off setpoint value based at least in part on the retrieved value.Type: GrantFiled: January 21, 2013Date of Patent: November 10, 2015Assignee: Ford Global Technologies, LLCInventors: David Alan Wong, Debasish Dhar, Manfred Koberstein, William Stewart Johnston, Alan Douglas Wallington, Tina Maurer

Patent number: 8205461Abstract: A method and system for detecting a low charge condition in an air conditioner for a vehicle. The system first determines whether noise factors are present that would interfere with reliably measuring a pressure delta. If noise factors are not present, the system determines a pressure delta value for the compressor by comparing the high side pressure when the clutch is engaged to a high side pressure when the clutch is disengaged. If the pressure delta value is less than a threshold value, a low charge condition may be recorded. When the number of low charge conditions detected exceeds a predetermined number of events, the system may set a temperature diagnostic trouble code, disable the air conditioning system and alert the driver of a potential problem.Type: GrantFiled: January 26, 2009Date of Patent: June 26, 2012Assignee: Ford Global Technologies, LLCInventors: William Stewart Johnston, David Alan Wong, Hugh Hamilton, Manfred Koberstein, Debasish Dhar
