Method and device for detecting the standstill of a vehicle

A device for detecting whether a vehicle is in standstill, the device comprising:

• a sensor interface configured to receive acceleration values from an acceleration sensor and rotational speed values from a rotational speed sensor;
• a memory;
• and
• a processor configured to:
• filter (i) an acceleration value in a first axis of the vehicle to obtain a filtered acceleration value in the first axis and (ii) a rotational speed value about a second axis of the vehicle that is oriented orthogonally to the axis to obtain a filtered rotational speed value in the second axis;
• normalize (i) the filtered acceleration value in the first axis by transforming the filtered acceleration value in the first axis using a respective normalization factor to obtain a normalized acceleration value in the first axis and (ii) the filtered rotational speed value in the second axis by transforming the filtered rotational speed value in the second axis using a respective normalization factor to obtain a normalized rotational speed value in the second axis;
• determine a first sum of the normalized acceleration value in the first axis and the normalized rotational speed value in the second axis;
• and
• detect whether the vehicle is in standstill depending on the first sum.

A non-transitory machine-readable storage medium configured to store computer program for detecting whether a vehicle is in standstill, the computer program being configured to, when executed by a processor, cause the processor to:

• filter, (i) an acceleration value in a first axis of the vehicle to obtain a filtered acceleration value in the first axis and (ii) a rotational speed value about a second axis of the vehicle that is oriented orthogonally to the axis to obtain a filtered rotational speed value in the second axis;
• normalize (i) the filtered acceleration value in the first axis by transforming the filtered acceleration value in the first axis using a respective normalization factor to obtain a normalized acceleration value in the first axis and (ii) the filtered rotational speed value in the second axis by transforming the filtered rotational speed value in the second axis using a respective normalization factor to obtain a normalized rotational speed value in the second axis;
• determine a first sum of the normalized acceleration value in the first axis and the normalized rotational speed value in the second axis;
• and
• detect whether the vehicle is in standstill depending on the first sum.
