Method and device for dynamic setting of a vehicle component
First Claim
1. A device for dynamically adjusting a vehicle component which affects operation of the vehicle, and whose behavior is influenced by a characteristic control variable, said device comprising:
- means for automatically or manually changing the characteristic control variable while traveling, via an actuator element;
a control unit which adjusts said actuator element in response to a change of said characteristic control variable, via actuation signals in accordance with a stored calculation rule; and
sensors for supplying measurement signals to said control unit for generating said actuation signals;
wherein,a measurement signal which corresponds to a vehicle state variable that reflects behavior of a vehicle operator is determined over a predefined time period;
at least one response characteristic value that characterizes an oscillation profile of measured vehicle state variables is determined and compared in a comparison unit of the control unit with an assigned setpoint value to determine whether the vehicle operator adapts to the change in the behavior of the vehicle component which results from a change in the characteristic control variable of the vehicle component;
an actuation signal, which is fed to the actuator element and which at least partially reverses the change in the characteristic control variable of the vehicle component, is generated, if the driver does not adapt to the change in the behavior of the vehicle component; and
whether the driver adapts to the change in behavior is determined by whether that at least one response characteristic value of the oscillation profile exceeds the assigned setpoint values.

Abstract
In a method for dynamically adjusting a vehicle component, a characteristic variable which influences the behavior of the vehicle component can be varied automatically or manually while traveling. A state variable which characterizes the behavior of the driver is first determined directly after a change in the characteristic variable, and the determined state variable is then compared with a setpoint variable. The change in the characteristic variable of the vehicle component is at least partially reversed if the state variable exceeds the setpoint variable.

3. A method for controlling operation of a vehicle having at least one component whose output affects vehicle dynamics in response to a characteristic control variable, said method comprising:
-
detecting a manually or automatically generated change in said characteristic control variable, which change causes a change of said vehicle dynamics; in response to said change of the characteristic control variable, measuring a vehicle state variable that characterizes a response of an operator of the vehicle to said change of vehicle dynamics; evaluating said measured vehicle state variable to determine whether said operator adapts to said change in vehicle dynamics; and reversing, at least partially, said change of the characteristic control variable if the driver does not adapt to the change in vehicle dynamics; wherein whether said operator adapts to the change of vehicle dynamics is determined by whether at least one oscillation parameter of said measured vehicle state variable exceeds a preset threshold value.

-
determining a vehicle state variable that indicates the behavior of the driver, over a predefined time period directly after a change in the characteristic control variable of the vehicle component; determining at least one response characteristic value that characterizes an oscillation profile of the vehicle state variable within a time period under consideration; comparing the determined at least one response characteristic value with an assigned setpoint value in order to determine whether the driver adapts to a change in the behavior of the vehicle component which results from the change in the characteristic control variable of the vehicle component; and reversing at least partially the change in the characteristic control variable of the vehicle component if the driver does not adapt to the change in the behavior of the vehicle component; wherein, whether the driver adapts to the change in behavior is indicated by whether one of the at least one response characteristic value of the oscillation profile exceeds the assigned setpoint value. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
