Electronic control system for a vehicle and method for determining at least one driver-independent intervention in a vehicle system
First Claim
1. An electronic control system for a vehicle,comprising a driver request module for determining characteristic quantities with respect to the driver'"'"'s request from data at least representative of pedal travels, movements of the foot changing between the pedals and the brake pressure of the brake system, anda risk calculator for determining risk potentials from predefined and current vehicle data and additional data, the risk calculator performing at least an assessment of the condition of danger of the vehicle and the occupants in the vehicle and, in case of need, outputs controlling interventions graded according to the risk potential for controlling actuators, andan arbitration unit for receiving outputs from the risk calculator and performing an assessment with the data determined in the driver request module with regard to the characteristic quantities determined in the driver request module depending on an action influencing the driving dynamics of the vehicle brought about by the controlling interventions and, depending on the result of the assessment, releasing the graded controlling interventions to a limited extent, releasing them in their entirety, or blocking them.

Abstract
In a method for determining at least one, preferably however several driver-independent interventions in a vehicle system, a risk calculator is used, whose input is supplied with predetermined vehicle data, ambience data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar data. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and, in accordance with the evaluation and optional additional criteria or weightings, outputs driving signals controlling actuators that modify or trigger the driving behavior of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists, etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority control.

22. A method for determining at least one driver-independent intervention into a vehicle system, including the steps of
determining a driver'"'"'s request in a driver request module including characteristic quantities with respect to the driver'"'"'s request, from data being at least representative of pedal travels, movements of a foot changing between pedals, and brake pressure of a brake system, determining a risk potential in a risk calculator from predefined and current vehicle data and additional data, including ambience data and driver data, and optionally data of persons inside and outside the vehicle, performing at least an assessment of the condition of danger of the vehicle and the occupants of the vehicle within the risk calculator, depending on the assessment and on further criteria, supplying outputs controlling interventions graded according to the risk potential to an arbitration unit for the purpose of controlling actuators, and performing an assessment in said arbitration unit with the data determined in the driver request module with regard to the driver'"'"' request depending on an action influencing the driving dynamics of the vehicle brought about by the controlling interventions, and initiating, from the arbitration unit, graded controlling interventions to a limited extent, releasing them without limitation or completely blocking them depending on the result of the assessment.
