Abstract

A method of start/stop engine control based on vehicle location and driving situation includes identifying the location and driving situation of a host vehicle, and classifying the location and the driving situation of the host vehicle based on the identified location and driving situation. The engine start/stop control is based on at least one of the location classification and driving situation classification.

First claim

What is claimed is:

1. A method of start/stop engine control based on vehicle location and driving situation comprising:
identifying the location of a host vehicle relative to an object in a path of the host vehicle using an on-board camera;
identifying the driving situation of the host vehicle using a traffic flow determination module configured to access traffic information from a V2V or V2I communication system;
classifying the location and the driving situation of the host vehicle; and
modifying the start/stop engine control based on the location classification and the driving situation classification by initiating an auto-start event when the distance between the host vehicle and the object in the path of the host vehicle increases;
wherein the modifying includes at least one of extending a period before engine shutdown, temporarily disabling engine shutdown, or avoiding engine restart.

2. The method of claim 1 , wherein identifying the driving situation further comprises sensing inputs from at least one of an accelerator pedal position sensor, a brake position sensor, a vehicle speed sensor, a clutch pedal position sensor, an engine speed sensor, and one or more transceivers.

3. The method of claim 1 , wherein identifying the driving situation further comprises using past driving history.

4. The method of claim 1 , wherein classifying the location further comprises using an artificial intelligence image recognition system to classify the location of the host vehicle based on previously classified location information.

5. The method of claim 1 , wherein classifying the driving situation further comprises comparing the identified driving situation information to information stored in a predetermined driving situation library.

6. The method of claim 1 , further comprising alerting a host vehicle user that engine start/stop operation has been modified.

7. A method of start/stop engine control based on vehicle location and driving situation comprising:
identifying the location of a host vehicle relative to an object in a path of the host vehicle using an on-board camera;
identifying the driving situation of the host vehicle using a traffic flow determination module configured to access traffic information from a V2V or V2I communication system to determine object location data and traffic flow data;
determining a likelihood that the host vehicle will change paths before reaching the object in the path of the host vehicle based on the object location data and the traffic flow data;
classifying the location and the driving situation of the host vehicle;
modifying the start/stop engine control based on the location classification and the driving situation classification by increasing a threshold period before triggering an auto-stop event it is determined that the likelihood that the driver will change the path of the host vehicle before reaching the object is greater than the likelihood that the driver will not change the path of the host vehicle before reaching the object, wherein the modifying includes at least one of extending a period before engine shutdown, temporarily disabling engine shutdown, or avoiding engine restart; and
alerting a host vehicle user that engine start/stop operation has been modified.

8. The method of claim 7 , wherein identifying the driving situation further comprises sensing inputs from at least one of an accelerator pedal position sensor, a brake position sensor, a vehicle speed sensor, a clutch pedal position sensor, an engine speed sensor, and determining a likelihood that the host vehicle will change paths is further based on the driving situation.

9. The method of claim 7 , wherein identifying the driving situation further comprises using past driving history.

10. The method of claim 7 , wherein classifying the location further comprises using an artificial intelligence image recognition system to classify the location of the host vehicle based on previously classified location information.

11. The method of claim 7 , wherein classifying the driving situation further comprises comparing the identified driving situation information to information stored in a predetermined driving situation library.
