Abstract

Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The response system can modify the control of two or more systems simultaneously in response to driver behavior.

First claim

1 - 20 . (canceled)

21 . A method of controlling vehicle systems in a motor vehicle, comprising:
determining a level of drowsiness based on monitoring information received from one or more monitoring devices; receiving operating information at a first vehicle system from one or more vehicle systems; detecting a hazard based on the operating information from the first vehicle system; modifying control of the first vehicle system based on the level of drowsiness and the hazard; selecting a second vehicle system that is different from the first vehicle system; communicating the level of drowsiness and information about the hazard from the first vehicle system to the second vehicle system; and modifying the control of the second vehicle system based on the level of drowsiness and the hazard.

22 . The method according to claim 21 , wherein the first vehicle system is connected to an electronic control unit and where the second vehicle system is connected to the electronic control unit.

23 . The method according to claim 21 , further including determining if the hazard still exists by the second vehicle system wherein modifying the control of the second vehicle system is based on the level of drowsiness and the determination if the hazard still exists.

24 . The method according to claim 21 , wherein the first vehicle system communicates with the second vehicle system through a network.

25 . The method according to claim 21 , wherein the control of the second vehicle system is coordinated with the control of the first vehicle system.

26 . The method according to claim 21 , wherein the first vehicle system is a blind spot indicator system and wherein the second vehicle system is an electronic power steering system.

27 . The method according to claim 26 , wherein the electronic power steering system is controlled to help prevent a driver from turning a steering wheel of the motor vehicle when the blind spot indicator system detects the hazard and when the blind spot indicator system determines the driver is drowsy based on the level of drowsiness.

28 . A method of controlling vehicle systems in a motor vehicle, comprising:
determining a level of drowsiness associated with a driver of the motor vehicle based on monitoring information received from one or more monitoring devices; operating a first vehicle system, the operation of the first vehicle system comprising:
detecting a hazard based on operating information from the first vehicle system;
modifying control of the first vehicle system based on the level of drowsiness and the hazard;
submitting information related to the hazard to a second vehicle system;
operating the second vehicle system, the operation of the second vehicle comprising:
receiving the information related to the hazard from the first vehicle system;
checking for the hazard; and
modifying the control of the second vehicle system based on the level of drowsiness and the hazard.

29 . The method according to claim 28 , wherein the level of drowsiness is a body state index having at least two values.

30 . The method according to claim 28 , wherein checking for the hazard further includes the second vehicle system determine whether the hazard still exists.

31 . The method according to claim 30 , wherein modifying the control of the second vehicle system is based on the level of drowsiness and whether the hazard still exists.

32 . The method according to claim 28 , wherein the submitted information includes instructions for the second vehicle system to check for potential hazards.

33 . The method according to claim 28 , wherein the modified control of the second vehicle system is coordinated with the modified control of the first vehicle system.

34 . A motor vehicle, comprising:
a monitoring system being configured to determine a level of drowsiness of a driver a first vehicle system and a second vehicle system in communication with the first vehicle system; the first vehicle system being capable of detecting at least one hazard; the second vehicle system being capable of detecting at least one hazard; wherein the operation of the first vehicle system can be modified according to the level of drowsiness and wherein the operation of the second vehicle system can be modified according to the level of drowsiness; and wherein the second vehicle system is configured to check for at least one hazard when the first vehicle system detects at least one hazard, wherein the second vehicle system checks for at least one hazard in response to information sent by the first vehicle system.

35 . The motor vehicle according to claim 34 , wherein the first vehicle system is connected to an electronic control unit and the second vehicle system is connected to the electronic control unit and wherein second vehicle system checks for at least one hazard in response to instructions from the electronic control unit.

36 . The motor vehicle according to claim 34 , wherein the motor vehicle includes three or more vehicle systems.

37 . The motor vehicle according to claim 36 , wherein the three or more vehicle systems check for hazards in response to instructions from an electronic control unit.

38 . The motor vehicle according to claim 36 , wherein the three or more vehicle systems are connected to one another using a network.

39 . The motor vehicle according to claim 36 , wherein the second vehicle system and a third vehicle system check for hazards in response to instructions from the first vehicle system.

40 . The motor vehicle according to claim 34 , further including a third vehicle system wherein the operation of the third vehicle system can be modified according to the level of drowsiness.
