Abstract
Official abstract text for this publication.
A method for detecting a standstill of a vehicle includes detecting the standstill of the vehicle using at least one sensor, and, when the standstill is detected using the at least one sensor, carrying out a test routine for checking the standstill of the vehicle. The test routine uses at least one signal from at least one rate-of-rotation sensor as an input value. The method further includes rejecting the detected standstill of the vehicle when the at least one signal from the at least one rate-of-rotation sensor indicates that there is no standstill of the vehicle.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for operating a vehicle, the method comprising: detecting standstill of the vehicle using at least one sensor of the vehicle; in response to the standstill being detected using the at least one sensor, carrying out a test routine for checking the standstill of the vehicle, wherein the test routine uses at least one signal from at least one rate-of-rotation sensor as an input value, the test routine including (i) pre-correcting an offset of the at least one rate-of-rotation sensor using a filter based on a weighted difference and a weighted variance of an output signal, (ii) forming an integrated signal by integrating at least one signal from at least one rate-of-rotation sensor in a predefined integration window, and (iii) determining the standstill of the vehicle in response to the integrated signal being below a predefined threshold value; rejecting the detected standstill of the vehicle when the at least one signal from the at least one rate-of-rotation sensor indicates that there is no standstill of the vehicle; and calibrating inertial sensors of the vehicle when it is confirmed based on the at least one signal from the at least one rate-of-rotation sensor that there is a standstill of the vehicle, the inertial sensors including the at least one rate-of-rotation sensor; determining a position of the vehicle using the inertial sensors; and operating the vehicle based on the position of the vehicle. 2. The method according to claim 1 , wherein the test routine includes assessing a variance of the at least one signal from the at least one rate-of-rotation sensor. 3. The method according to claim 2 , wherein it is detected that there is no standstill when the variance of the at least one signal from the at least one rate-of-rotation sensor exceeds a threshold value. 4. The method according to claim 1 , wherein the test routine is carried out in order to detect when the vehicle is positioned on a turntable and is moved with the turntable. 5. The method according to claim 1 , wherein the at least one rate-of-rotation sensor is a yaw rate sensor. 6. The method according to claim 1 , wherein a computer program is configured to carry out the method. 7. The method according to claim 6 , wherein the computer program is stored on a non-transitory machine-readable storage medium. 8. The method according to claim 1 , wherein a control unit for the vehicle is configured to carry out the method.
