Abstract
Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a driver's slow reaction time, attention lapse and/or alertness. 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 systems that may be modified include: visual devices, audio devices, tactile devices, antilock brake systems, automatic brake prefill systems, brake assist systems, auto cruise control systems, electronic stability control systems, collision warning systems, lane keep assist systems, blind spot indicator systems, electronic pretensioning systems and climate control systems.
Claims69
A method of controlling one or more vehicle systems in a motor vehicle, comprising:
- receiving monitoring information, the monitoring information including information from the one or more vehicle systems and information about a state of the autonomic nervous system of a driver;
- determining a body state index of the driver based on the monitoring information;
- changing an operating parameter of the one or more vehicle systems based on the body state index, wherein the operating parameter is used to determine activation of a particular function of the one or more vehicle systems;
- determining if the driver is drowsy based on the body state index;
- and
- modifying the control of the one or more vehicle systems based the operating parameter when the driver is drowsy.
A method of controlling a vehicle system in a motor vehicle, comprising:
- receiving information from one or more sensors, the sensors being capable of detecting information about the autonomic nervous system of a driver and information about one or more vehicle systems;
- determining a body state index of the driver based on the information about the autonomic nervous system of a driver and information about the one or more vehicle systems;
- determining if the driver is drowsy based on the body state index;
- and
- modifying the control of the one or more vehicle systems when the driver is drowsy.
A method of controlling a vehicle system in a motor vehicle, comprising:
- receiving monitoring information;
- determining a body state index for a driver, the body state index characterizing drowsiness and based on the monitoring information;
- determining a control coefficient based on the body state index, wherein the control coefficient is a value that varies as a function of the body state index;
- determining a control parameter using the control coefficient, wherein the control parameter is used to determine activation of a particular function of the vehicle system;
- and
- operating the vehicle system using the control parameter.
