Abstract

The invention relates to a hazard-prevention system for a vehicle. The vehicle has devices for sensing driving state variables, for sensing ambient data and for sensing the driver'"'"'s activity, and a data processing device. The data processing device is provided for processing the sensed data and for actuating a safety device in accordance with a predefined control strategy. According to the invention, the vehicle has a device for identifying the driver, and the data processing device derives a driver load factor related specifically to the driver from the driving state variables, the ambient data and the data relating to the activity of the driver, and said driver load factor is used to adapt the control strategy.

Claims

1. Hazard-prevention system for a vehicle having:

a device for sensing driving state variables

a device for sensing ambient data

a device for sensing the driver'"'"'s activity

a data processing device for processing the sensed data and for actuating a safety device in accordance with a predefined control strategy,

characterized in that

the vehicle has a device for identifying the driver,

the data processing device derives a driver load factor related specifically to the driver which is derived from the driving state variables, the ambient data and the data relating to the activity of the driver,

the vehicle has a device for adapting the control strategy, which uses the individual driver load factor for this purpose.

2. Hazard-prevention system for a vehicle according to claim 1, characterized in that

the vehicle has a device for storing the driver-related history, which contains data which is characteristic of the driver,

data processing device additionally used as the driver-related history to derive the individual driver load factor.

3. Hazard-prevention system for a vehicle according to one of claims 1 and 2, characterized in that the safety device comprises an information and warning system.

4. Hazard-prevention system for a vehicle according to one of claims 1 and 2, characterized in that the safety device comprises a system for controlling the dynamics of vehicle movement.

5. Hazard-prevention system for a vehicle according to one of claims 1 and 2, characterized in that the safety device comprises a vehicle occupant protection system which acts on the movement of an occupant of a vehicle and is intended to make the consequences of accidents less severe.
