8. 8. The vehicle of claim 1, wherein the controller derates the display control module to shut down one or more screens based on available power from the one or more batteries.
9. 9. The vehicle of claim 8, wherein the controller de-rates the lock control module to shut off power supplied to operate an electronic lock.
10. 10. The vehicle of claim 9, wherein the controller de-rates the audio control module to shut off one or more internal audio speakers.
11. 11. The vehicle of claim 10, wherein the controller de-rates the modem control module to shut off power.
12. 12. A method of controlling an electronic module on a vehicle in a tail gate audio mode, the method comprising the steps of: entering a tail gate audio mode on the vehicle; storing electrical energy in one or more batteries; Supplying the electrical energy to a plurality of electronic modules including an audio control module, a display control module, a lock control module, a brake control module, and a modem control module; Powering one or more audio devices with the power in the tail gate audio mode, and One or more of the plurality of electronic modules are de-rated based on an expected energy consumption and the available power in the one or more batteries to reduce power consumption.

Description

Vehicle and method with tail gate audio mode Technical Field The present disclosure relates generally to motor vehicles that may operate in a tail gate audio mode, and more particularly to a vehicle and method that effectively controls a motor vehicle electric module to provide extended tail gate audio mode operation with an audio device. Background Motor vehicles are typically equipped with a plurality of audio speakers and exciters to provide sound for entertainment and feedback. Some motor vehicles may be used for travel picnic in a tail gate audio mode, where the motor vehicle is parked in park, and the audio speaker and exciter may be operated to provide sound entertainment. It would be desirable to provide a vehicle configured with a tail gate audio mode that provides efficient battery energy utilization.
