Abstract
A method is for calibrating and/or initializing a steering sensor of a steering system, in particular during operation of the steering system in a vehicle. The steering system includes a steering handle and a torque sensor associated with the steering handle. The steering sensor is configured to detect a deflection position of the steering handle. A torque parameter is determined by determining a torque for each of a plurality of different deflection positions of the steering handle, and is compared with a reference parameter in order to calibrate and/or initialize the steering sensor.

A method for calibrating and/or initializing a steering sensor of a steering system in a vehicle, the steering system comprising a steering handle and a torque sensor associated with the steering handle, the method comprising:
- detecting a deflection position of the steering handle using the steering sensor;
- determining a torque parameter by determining a torque for each of a plurality of different detected deflection positions of the steering handle;
- and
- comparing the determined torque parameter with a reference parameter in order to calibrate and/or initialize the steering sensor.
A vehicle, comprising:
- a steering system including a steering handle, a steering sensor associated with the steering handle and configured to detect a deflection position of the steering handle, and a torque sensor associated with the steering handle for detecting a torque;
- and
- a computing unit configured to determine a respective torque for a plurality of different deflection positions of the steering handle and to generate a torque parameter based on the determined torque, the computing unit further configured to compare the torque parameter with a reference parameter in order to calibrate and/or initialize the steering sensor.
