Abstract
An apparatus and method for classifying a driver's activity state use sensor data relating to at least one vehicle operating condition to determine driver activity and classify into one of at least two states. A two state classifier (200) uses inputs related to vehicle monitors (210), driving conditions (212), driver activity (214), vehicle controls (216), and driver identification (218) to set an output (204) to a status corresponding to “maneuver” and “non-maneuver.”
Claims24
A method of classifying an activity state of a driver, the method comprising:
- providing a statistical classifier, the statistical classifier being at least one of a C4.5, a RIPPER, and a Quadratic classifier, and configuring the statistical classifier as an at least two-state activity classifier operable to recognize at least a first driving state corresponding to a maneuver activity and a second driving state corresponding to a non-maneuver activity;
- receiving sensor data relating to at least one vehicle operating condition;
- classifying the driver activity using the configured statistical classifier into one of the at least first and second driving states based upon the sensor data;
- and
- utilizing the classified state of the at least first and second driving states to determine whether to send an event to the driver of the vehicle.
A two-state classification apparatus for classifying an activity state of a driver, the classification apparatus comprising:
- an input for receiving sensor data relating to at least one vehicle condition;
- and
- a processor coupled to the input, wherein the processor analyzes the sensor data to determine a classification of the activity state of the driver using a statistical classifier, wherein the statistical classifier used by the processor is at least one of a C4.5, a RIPPER, and a Quadratic classifier that is configured as an at least two-state activity classifier operable to recognize at least a first driving state corresponding to a maneuver activity and a second driving state corresponding to a non-maneuver activity, and wherein the processor determines the classification of the activity state of the driver using the statistical classifier as one of a maneuver and non-maneuver and utilizes the classification of the activity state to determine whether to send an event to the driver of the vehicle.
A vehicle arranged and constructed to use a classification of an activity state of a driver comprising:
- a classification apparatus using a statistical classifier for providing a signal corresponding to one of a maneuver and non-maneuver, wherein the statistical classifier used by the apparatus is at least one of a C4.5, a RIPPER, and a Quadratic classifier that is configured as an at least two-state activity classifier operable to recognize at least a first driving state corresponding to a maneuver activity and a second driving state corresponding to a non-maneuver activity, the signal being based on sensor data related to at least one operational condition;
- and
- a device operable to use the signal for determining a timing for sending the driver an event.
