System and method for responding to driver state
A method for controlling vehicle systems includes receiving monitoring information from one or more monitoring systems and determining a plurality of driver states based on the monitoring information from the one or more monitoring systems. The method includes determining a combined driver state based on the plurality of driver states and modifying control of one or more vehicle systems based on the combined driver state.
1. A method of controlling a vehicle, comprising:
receiving vehicle information from one or more vehicle systems;
determining a vehicular state of the vehicle based on the vehicle information, wherein the vehicular state indicates the vehicle is in a stopped state;
receiving monitoring information about a driver from a monitoring system, wherein the monitoring information includes head movement information about the driver;
determining a driver state index based on the head movement information by analyzing a head-look of the driver relative to the vehicle; and
modifying control of the vehicle to automatically move based on the vehicular state and the driver state index.
2. The method of claim 1 , wherein if the head-look of the driver is forward-looking relative to the vehicle, and the driver is determined to be attentive, modifying control of the vehicle includes controlling the vehicle to automatically move forward with respect to a preceding vehicle.
3. The method of claim 1 , wherein the monitoring information includes hand contact information about contact between the driver and a steering wheel of the vehicle.
4. The method of claim 3 , wherein modifying control of the vehicle includes modifying control of the vehicle to automatically move based on the vehicular state, the driver state index, and the hand contact information.
5. The method of claim 3 , wherein modifying control of the vehicle includes modifying control of the vehicle to automatically move without manual input from the driver based on the vehicular state, the driver state index, and the hand contact information.
6. The method of claim 3 , wherein if the head-look of the driver is forward-looking relative to the vehicle based on the head movement information, and there is no hand contact with the steering wheel based on the hand contact information, modifying control of the vehicle includes controlling the vehicle to automatically move forward.
7. The method of claim 3 , wherein determining the driver state index includes determining a plurality of driver states based on the monitoring information, wherein the plurality of driver states includes a first driver state comprising the head movement information and a second driver state comprising the hand contact information.
8. The method of claim 7 , including determining a combined driver state index based on the plurality of driver states, and wherein modifying control of the vehicle includes modifying control of the vehicle based on the combined driver state index.
9. The method of claim 1 , wherein upon determining the vehicle is in the stopped state based on the vehicular state and the driver is attentive based on the driver state index, modifying control of the vehicle includes modifying a control status of the one or more vehicle systems to auto control without a manual input from the driver.
10. The method of claim 4 , wherein the one or more vehicle systems includes a low speed follow system and an automatic cruise control system.
11. A system for controlling a vehicle, comprising:
a monitoring system; and
an electronic control unit including a processor, wherein the processor:
receives vehicle information from one or more vehicle systems;
determines a vehicular state of the vehicle based on the vehicle information, wherein the vehicular state indicates the vehicle is in a stopped state;
receives monitoring information about a driver from the monitoring system, wherein the monitoring information includes head movement information about the driver;
determines a driver state index based on the head movement information by analyzing a head-look of the driver relative to the vehicle; and
modifies control of the vehicle to automatically move based on the vehicular state and the driver state index.
12. The system of claim 11 , wherein if the head-look of the driver is forward-looking relative to the vehicle, and the driver state is determined to be attentive, the processor modifies control of the vehicle to automatically move forward with respect to a preceding vehicle.
13. The system of claim 11 , wherein the monitoring information includes hand contact information about contact between the driver and a steering wheel of the vehicle.
14. The system of claim 13 , wherein the processor modifies control of the vehicle to automatically move based on the vehicular state, the driver state index, and the hand contact information.
15. The system of claim 13 , wherein the processor modifies control of the vehicle to automatically move without manual input from the driver based on the vehicular state, the driver state index, and the hand contact information.
16. The system of claim 13 , wherein the processor determines the head-look of the driver is forward-looking relative to the vehicle based on the head movement information, and the processor determines there is no hand contact with the steering wheel based on the hand contact information, the processor controls the vehicle to automatically move forward.
17. The system of claim 13 , wherein the processor determines a plurality of driver states based on the monitoring information, wherein the plurality of driver states includes a first driver state comprising the head movement information and a second driver state comprising the hand contact information.
18. The system of claim 17 , wherein the processor determines a combined driver state index based on the plurality of driver states, and the processor modifies control of the vehicle based on the combined driver state index.
19. The system of claim 11 , wherein the processor determines the vehicle is in a stopped state based on the vehicular state and the driver is attentive based on the driver state index, the processor modifies a control status of the one or more vehicle systems to auto control without a manual input from the driver.
20. The system of claim 19 , wherein the one or more vehicle systems includes a low speed follow system and an automatic cruise control system.
