摘要:
A method and a control unit are provided for detecting when the driver of a motor vehicle becomes inattentive. In order to be able to reliably draw conclusions about the presence of inattentiveness of the driver, it is proposed to observe not only a steering inactivity phase but also a steering action which follows the steering inactivity phase. A detected implementation of the steering inactivity phase and of the steering action are logically combined with one another, and the result of this logic combination is then used as a measure of the severity of the inattentiveness of the driver. In addition, the measure of the severity of the inattentiveness of the driver depends on at least one driver-specific parameter which is determined during the execution of the method. The inattentiveness of the driver can also be detected during the time interval in which the at least one driver-specific parameter is determined.

A method and a device are provided for detecting when the driver of a motor vehicle becomes inattentive. A steering inactivity phase and a subsequent steering action are detected in this context. A steering inactivity phase is detected if the absolute value of the steering wheel angle, of its change over time, or both, during a predefined time threshold value, does not exceed a first threshold value. A steering action is detected if the absolute value of the steering wheel angle, of its change over time, or both, exceeds a second threshold value. The first threshold value and the second threshold value are modified in a driver-specific fashion.
摘要:
A method for driver-behavior-adaptive control of a variably adjustable motor vehicle accessory. One or more parameters indicative of driver behavior are sensed and a pertinent driver behavior is ascertained therefrom. Accessory adjustment is performed variably as a function of the driver behavior that was ascertained. The driver behavior is ascertained in terms of a long-term driving manner component, and a short-term dynamic demand component and/or a steady-speed request component. Accessory adjustment is performed, if a short-term dynamic demand exists, in accordance with an adjustment characteristic having a dynamic level corresponding at least to that dynamic demand. When a constant-speed request exists, accessory adjustment is performed in accordance with a relevant low-dynamic adjustment characteristic. Otherwise, accessory adjustment is performed in accordance with an adjustment characteristic determined by the long-term driving manner component.

A method and a computer program for identifying when the driver of a vehicle, in particular a motor vehicle, is not paying attention. In order to make it possible to make a more reliable statement on the presence of any inattentiveness by the driver, the method observes a steering action following a steering quiescent phase, in addition to detecting the steering quiescent phase. The extent of the steering quiescent phase and of the steering action found are logically linked to one another, and the result of this logical operation is then used as a measure for the severity of the inattentiveness of the driver.

In a method and in a device for detecting when the driver of a motor vehicle becomes tired, the tiredness is determined as a function of a detected steering inactivity phase and a subsequent steering action. In this context, the steering inactivity phase is logically combined with the steering actions and the logic combination is stored at various times. The logic combination is stored with an assigned weighting factor, and the weighting factor is determined as a function of a classification of a steering situation.

A method for influencing the load on a driver while driving a motor vehicle, in which a workload is determined from physiological driver data detected by sensors, and to an apparatus for carrying out the method. The load or the workload on the driver is kept in an optimum workload range and brought back to this optimum range if there is any discrepancy, thus ensuring an optimum driver performance level and attention level. For this purpose, vehicle systems are driven as a function of the detected workload value in such a way that the driver is influenced via his visual, auditory or tactile sense channels in such a way that his workload value returns to a value in the optimum workload range.
摘要:
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.
摘要:
A method for assessing actuations of the accelerator by a vehicle driver to detect the nervousness of the driver, the cumulative path covered by the accelerator, in terms of amount, being evaluated within a predefined time window when the change in velocity is less than a predetermined threshold value and/or the change in position of the accelerator is less than a predetermined threshold value within this time window. Furthermore, alternatively and/or additionally, the number of reversals of the algebraic sign of the time derivation of the accelerator position can be taken into account.

A method for recognizing a spontaneous demand by a driver of a motor vehicle for a dynamic response, the extent of the actuation of an operating device being compared to a threshold value, and the demand for a dynamic response being recognized when the extent of actuation lies above a specific threshold value, and, when comparing the extent of actuation to the threshold value, allowance being made for the manner in which the vehicle driver normally actuates the operating device.
