METHOD FOR REDUNDANT MONITORING OF DRIVING FUNCTIONS

A method for redundant monitoring of driving functions of an automatedly driving motor vehicle, with a first control system. The first control system includes a first control unit, a first actual-value sensor and a first controller. Based on ascertained actual values of the first actual-value sensor and control specification values, the first control unit controls the first controller with control values. A redundant second control system includes a second control unit, a second actual-value sensor, and a second controller. The second controller is controllable via the second control unit with control values ascertained based on ascertained actual values of the second actual-value sensor and control specification values. The method includes measuring the actual values using the second actual-value sensor, comparing the actual values to the control specification values for the second control unit, determining a deviation, and ascertaining a defect in the first control system depending on the deviation.
