Abstract:
A method of controlling a vehicle having an automated driving system configured to control a vehicle subsystem includes determining an autonomous actuation event for the vehicle subsystem. The method additionally includes detecting a presence of a vehicle occupant. The method also includes, in response to an anticipated change in vehicle dynamics based on the determined actuation event and to the detected presence of the vehicle occupant, providing a notification to the occupant before initiation of the actuation event. The method further includes generating an actuation command based on the actuation event and controlling the vehicle subsystem according to the actuation command via the automated driving system.
Abstract:
A vehicle including a powertrain system that includes an electric machine electrically connected to a power inverter is described, wherein the powertrain system is operative in an electric vehicle mode to generate propulsion torque. A method for controlling the powertrain system includes determining a vehicle speed, and determining a preferred audible sound to be generated by the powertrain system when operating in the electric vehicle mode at the vehicle speed. A control signal for the power inverter is determined, and is associated with operating the powertrain system in the electric vehicle mode at the vehicle speed. The preferred audible sound is incorporated into the control signal for the power inverter, and the power inverter is controlled to operate the electric machine employing the control signal and the preferred audible sound.
Abstract:
A system in a vehicle including at least one sound quality valve arranged in an exhaust system of the vehicle includes a sound quality valve control module that determines whether one or more criteria for opening the sound quality valve are met, selectively actuates the sound quality valve to an open position if the one or more criteria for opening the sound quality valve are met, and maintains the sound quality valve in a closed position if a required one of the one or more criteria for opening the sound quality valve is not met. A downshift detection module determines whether aggressive driving behavior is detected. If the aggressive driving behavior is detected, the sound quality valve control module actuates the sound quality valve to the open position regardless of whether the required one of the one or more criteria for opening the sound quality valve is met.
Abstract:
A non-bussed control module that receives an audio code is provided. The non-bussed control module includes a tone processing module, a self-diagnostic module, and a reporting module. The tone processing module receives the audio code, and sends a trigger signal if the audio code is received. The self-diagnostic module performs a self-diagnostic test for the non-bussed control module if the trigger signal is received, and generates a diagnostic signal indicative of the self-diagnostic test. The reporting module receives the diagnostic signal and determines a type of fault based on the diagnostic signal.
Abstract:
A vehicle having a system is provided. The system has at least one operating output. The system includes an occupant module and a vehicle system module. The occupant module receives at least one occupant signal indicative of occupants currently located within the vehicle, and determines a current number and location of occupants in the vehicle based on the occupant signal. The vehicle system module receives as input the current number of occupants located in the vehicle. The vehicle system module is configured for determining whether the current number of occupants located in the vehicle is less than a total number of occupants the vehicle is configured to seat. The vehicles system module is configured for adjusting the at least one operating output of the system if the current number of occupants located in the vehicle is less than the total number of occupants the vehicle is configured to seat.

Abstract:
A vehicle system is provided that includes a sound augmentation system with a sound augmentation generator that produces an augmented audio output to drive at least one audio output based on a transfer function and a plurality of audio tuning parameters. The vehicle system also includes a sound augmentation system health monitor that compares a feedback of the augmented audio output to a level of at least one input relative to at least one environmental condition to determine a current performance level of the sound augmentation system. The sound augmentation system health monitor also determines a difference between the current performance level of the sound augmentation system and at least one performance threshold level, and initiates an alert upon determining that the difference is at a predetermined level.

The vehicle system also includes a sound augmentation system health monitor that determines a current performance level of the sound augmentation system based on at least one audio input and a feedback of the augmented audio output, and triggers a transfer function update prompt based on a difference between the current performance level and an expected performance level being at a threshold level. A user interface outputs the transfer function update prompt and receives a transfer function calibration request in response to the transfer function update prompt. A transfer function calibration module drives a calibration sequence on at least one audio output and monitors at least one audio input to determine an updated transfer function.
