The invention relates to an evaluation device for fault-tolerant evaluation of at least four redundant sensor signals (S1a, S2a, S1b, S2b) for a motor control unit of a motor vehicle steering system, comprising two control units (2a, 2b), which are designed to be redundant in respect of one another and which each have at least two inputs (3a, 4a; 3b, 4b) for receiving one each of the redundant sensor signals (S1a, S2a, S1b, S2b), an output (5a, 5b) for outputting an output signal (A1, A2), and a communication interface (6a, 6b), which is connected to the communication interface (6b, 6a) of the respective other control unit (2a, 2b) for transmitting and receiving an exchange signal (Ex1, Ex2), and a logic circuit (7a, 7b), which, depending on paired comparisons between the signals (S1a, S2a, Ex2; S1b, S2b, Ex1) received at the inputs (3a, 4a; 3b, 4b) and at the communication interface (6a, 6b), is designed to choose from these signals (S1a, S2a, Ex2; S1b, S2b, Ex1) the output signal (A1, A2) and the exchange signal (Ex1, Ex2) and to connect them through to the output (5a, 5b) and accordingly to the communication interface (6a, 6b) by means of selection circuits (8a, 9a; 8b, 9b). The invention also relates to a motor vehicle steering system comprising an evaluation device of this kind.
