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.
Claims18
A method of controlling a vehicle system in a vehicle, comprising:
- receiving monitoring information about a state of a driver from a monitoring system of the vehicle;
- receiving vehicle operating information about the vehicle system and the state of the driver from the vehicle system;
- calculating a driver state index comprising the monitoring information about the state of the driver and the vehicle operating information about the vehicle system and the state of the driver;
- determining a control coefficient using the driver state index;
- changing a control parameter of the vehicle system using the driver state index and the control coefficient, wherein the control parameter is a system status of the vehicle system;
- and
- modifying control of the vehicle system using the control parameter.
A response system for controlling a vehicle system in a vehicle, comprising:
- a monitoring system including one or more sensors that detect monitoring information, wherein the monitoring information is information about a state of a driver;
- and
- an electronic control unit that receives the monitoring information from the monitoring system and vehicle operating information about the vehicle system and the state of the driver from the vehicle, determines a driver state index of the driver comprising the monitoring information about the state of the driver and the vehicle operating information about the vehicle system and the state of the driver, determines a control coefficient using the driver state index, and modifies a control parameter of the vehicle system based on the driver state index and the control coefficient, wherein the control parameter is a value that defines an operational state of the vehicle system, and wherein the electronic control unit controls the vehicle system using the control parameter.
