| 摘要 |
The invention relates to a sensor assembly on a steering column (2) of a motor vehicle and comprises at least two sensors (10, 11, 20, 21) for redundantly detecting the torque applied to the steering column (2) and/or for detecting the angle of rotation of the steering column (2). The sensors (10, 11, 20, 21) of the sensor assembly (9) are connected to a voltage supply (VDD, GND) by means of electrical lines (30, 31, 32, 33), wherein each of the sensors (10, 11, 20, 21) transmits data to a control unit (8) by means of a signal line (16, 17, 26, 27). In order to reduce the number of connecting cables to the control unit (8), the signal lines (16, 17, 26, 27) of two sensors (10, 11, 20, 21), according to the invention, are connected to the control unit (8) by means of a common data line (34, 35, 36). Each sensor (10, 11, 20, 21) is to be controlled individually by the control unit (8) by means of the data line (34, 35, 36) and the signal line (16, 17, 26, 27) in such a way that, upon a signal (53) of the control unit (8), the addressed sensor (10, 11, 20, 21) outputs the data of said sensor to the control unit (8) by means of the signal line (16, 17, 26, 27) and the data line (34, 35, 36). |
