Claim Text:
1. A method for a driver assistance system, said method comprising: with at least one sensor unit, detecting surroundings and producing corresponding sensor data; with a first control unit, calculating a surroundings model based on the sensor data, calculating a first control variable for a first driver assistance application, and transmitting a first control signal in accordance with the first control variable; with a second control unit, calculating a second control variable for a reduced second driver assistance application and a second control signal based on the sensor data; with the second control unit, determining a third control signal when a current value of the first control signal is not available, wherein a value of the second control signal is used for the third control signal, or the third control signal is calculated based on the second control signal and a last transmitted value of the first control signal, or the surroundings model is transmitted to the second control unit and the third control signal is calculated based on the surroundings model; and actuating an actuator of the driver assistance system dependent on the first control signal when the current value of the first control signal is available, and actuating the actuator dependent on the third control signal when the current value of the first control signal is not available.
