Publication number: 20230373268Abstract: A method for controlling a rear glass defroster for a vehicle upon start-up is presented. First, one or more factors are determined, which are selected from a temperature of an environment immediately outside the vehicle, a humidity of the environment, a dew point of the environment, a barometric pressure of the environment, a temperature of a rear glass of the vehicle, a temperature of an internal cabin of the vehicle and a sun load on the vehicle. Next, the one or more factors are compared to one or more corresponding predetermined thresholds or ranges that are indicative of conditions suitable for frost formation on a rear glass of the vehicle. Then, if the comparison indicates that the one or more factors meet the frost formation conditions, the rear glass defroster is activated. A vehicle rear-glass defrost system which uses the foregoing method is also presented.Type: ApplicationFiled: May 19, 2022Publication date: November 23, 2023Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Vipul M.

Patent number: 9625510Abstract: In an example of a method for performing vehicle antenna diagnostics, a transmitting and receiving (TX/RX) antenna of a multiple input multiple output (MIMO) antenna assembly of a vehicle is electronically caused to emit a check signal. A response of a receiving only (RX) antenna of the MIMO antenna assembly is electronically detected in response to the check signal. A received signal strength indictor output is generated in response to the response of the RX antenna. The received signal strength indictor output is converted to a digital signal. The integrity of the MIMO antenna is determined after comparing the digital signal with an expected power level of the RX antenna.Type: GrantFiled: September 8, 2015Date of Patent: April 18, 2017Assignee: GM Global Technology Operations LLCInventors: Vipul M.

Patent number: 7613438Abstract: Methods are provided for reducing impulse noise effects in a motor vehicle radio. One method includes the steps of first detecting impulse noise received by the motor vehicle radio. The received impulse noise is classified as either short pulse width impulse noise or as long pulse width impulse noise. The short pulse width impulse noise can generally be blanked without seriously affecting the audio quality of the radio. For the long pulse width impulse noise, a maximum long pulse width blanking repetition rate is set and such impulse noise pulses are blanked at a blanking rate less than the maximum long pulse width blanking repetition rate.Type: GrantFiled: February 9, 2005Date of Patent: November 3, 2009Assignee: GM Global Technology Operations, Inc.Inventor: Vipul M.
