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 powertrain system, comprising:

a global position satellite (GPS) module configured to electrically exchange data with an electronic GPS network to obtain GPS coordinates and determine a location of a vehicle operated by the powertrain;

an air quality 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;

a powertrain control module that generates electrical signals to communicate with the sensor and a remotely located municipality module, the municipality module corresponding to the location and having a microcontroller configured to transmit at least one stored powertrain parameter, the powertrain control module configured to compare the detected quality of air to a threshold value, determine at least one current operating condition of the powertrain system, and to select a different operating mode of the powertrain system among a plurality of operating modes based on a comparison between the at least one current operating condition and the at least one stored powertrain parameter, the different operating mode configured to reduce at least one emission exhausted from the vehicle that contributes to a low air quality measured by the air quality sensor;

wherein the powertrain control module determines 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 outputs an electrical control signal that controls a mechanical drive clutch to disengage the engine when the at least one risk factor does not exist, 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 powertrain system of claim 1, further comprising:

an internal combustion engine (ICE) operable in response to combusting hydrocarbon fuel;

a hybrid electric motor (HEM) operable in response to power from a rechargeable electronic battery;

a drive clutch that selectively engages and disengages at least one of the ICE and the HEM to a drive shaft for driving a vehicle; and

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

3. The powertrain system of claim 2, wherein the control module controls the drive clutch based on the comparison between the at least one current operating condition and the at least one stored powertrain parameter.

4. The powertrain system of claim 3, wherein the comparison is based on a maximum exhausted carbon emission level stored in the municipality module and at least one of a current carbon emission level exhausted from the ICE and the current quality of air detected by the sensor.

5. The powertrain system of claim 4, wherein the comparison is further based on a risk factor associated with at least one of the driver of the vehicle and faulty operation of the vehicle.

6. The powertrain system of claim 5, wherein the risk factor includes health of the driver and an electrical charge level of the rechargeable electronic battery.

7. A method of controlling a powertrain system of a vehicle, the method comprising:

determining a quality of air surrounding the vehicle based on an ozone level of the local atmosphere and a carbon level of the local atmosphere using an air quality sensor;

executing, with a powertrain control module, the steps comprising;

comparing the determined quality of air to a threshold value;

determining 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

selecting an operation mode of the powertrain system that reduces at least one emission exhausted from the vehicle that affects the determined quality of air 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.

8. The method of claim 7, wherein the quality of air is based on at least one of an ozone level of the local atmosphere and a carbon level of the local atmosphere.

9. The method of claim 8, further comprising determining a presence of at least one risk factor corresponding to at least one of the vehicle and the driver of the vehicle, and selecting the determined operation mode of the powertrain mode using the electronic vehicle control module when the at least one risk factor is below a risk threshold and the quality of air is below the threshold value.

10. The method of claim 9, further comprising alerting a request to change the operating mode of the powertrain system.
