Abstract

A vehicle control system to control operation of a vehicle includes a powertrain system operable according to a plurality of operating modes that drive the vehicle. A sensor is mounted to the vehicle to detect a quality of air surrounding the vehicle. A vehicle control module is configured to select an operating mode of the powertrain system. The operating mode is selected to reduce at least one emission exhausted from the vehicle that contributes to a low air quality measure by the sensor.

Claims

1. A vehicle control system to control operation of a vehicle, comprising:

a powertrain system operable according to a plurality of operating modes to drive the vehicle;

a sensor mounted to the vehicle to detect a quality of air based on an ozone level of the local atmosphere and a carbon level of the local atmosphere surrounding the vehicle; and

a vehicle control module configured to compare the detected quality of air to a threshold value, determine a presence of at least one risk factor indicating a risk of incapacitating a driver of the vehicle in response to disengaging an internal combustion engine of the vehicle, and select an operating mode of the powertrain system to reduce at least one emission exhausted from the vehicle that contributes to a low air quality measured by the sensor in response to determining the at least one risk factor is below a risk threshold and the quality of air is below the threshold value, the at least one risk factor selected from a group including risk factors associated with the vehicle, the driver of the vehicle, road conditions, weather, and a distance at which the vehicle is from a battery charging station.

2. The vehicle control system of claim 1, wherein the powertrain system includes an internal combustion engine (ICE) operable in response to combusting hydrocarbon fuel, and a hybrid electric motor (HEM) operable in response to power from a rechargeable electronic battery.

3. The vehicle control system of claim 2, wherein the plurality of operating modes of the powertrain system comprises an engine-only mode that operates the powertrain using only the ICE during an entire trip duration, a charge-depleting mode that operates the powertrain using only the HEM over an entire trip duration, a blended mode that operates the powertrain system using both the ICE and the HEM over an entire trip duration, and a mixed mode that operates the powertrain system using a combination of the charge-depleting mode and the blended mode during an entire trip duration.

4. The vehicle control system of claim 3, wherein the vehicle control module determines at least one current operating parameter of the powertrain system and communicates the at least one current operating parameter to a municipality control module that stores at least one engine parameter, and wherein the municipality control module outputs a control signal instructing the vehicle control module to output at least one clutch control signal in response to a comparison between the current operating parameter and the at least one engine parameter.

5. The vehicle control system of claim 4, wherein the powertrain system further includes a drive clutch interposed between the ICE and the HEM, the drive clutch configured to selectively engage and disengage the ICE and the HEM in response to the clutch control signal.

6. The vehicle control system of claim 5, wherein the clutch control signal includes a first clutch control signal to engage and disengage the ICE and a second clutch control signal different from the first clutch control signal to engage and disengage the HEM.

7. The vehicle control system of claim 6, wherein the at least one engine parameter stored in the municipality module includes a maximum level of exhausted carbon emissions.

8. The vehicle control system of claim 7, further comprising a dash panel that alerts the driver of a mitigation factor, the alert including at least one of displaying an indicator and outputting a sound.

9. The vehicle control system of claim 8, wherein the mitigation factor includes indicating a change in the operating mode, requesting a change in the operating mode, and indicating payment of a fee in exchange to maintain a current operating mode.
