Method and device for recognising a state of standstill of a motor vehicle

Method for operating braking equipment of a motor vehicle which automatically produces braking forces when the motor vehicle is in a state of standstill in order to hold the motor vehicle at a standstill, this method comprising the following steps:

• specifying at least one change of position parameter which defines a change of position of a motor vehicle which may occur in a travelling state,
• detecting an actual change of position of the motor vehicle,
• establishing at least one actual change of position parameter which characterises the actual change of position,
• comparing the at least one actual change of position parameter with a corresponding one of the at least one specified change of position parameters in order to determine whether the at least one actual change of position parameter characterises a travelling state for the motor vehicle, and
• generating a first signal which reproduces a travelling state for the motor vehicle if the at least one actual change of position parameter characterises a travelling state, or a second signal which reproduces a state of standstill for the motor vehicle if the at least one actual change of position parameter characterises a state of the motor vehicle which is not a travelling state,
• wherein the at least one change of position parameter is associated with at least one of change of inclination of the motor vehicle about its longitudinal axis and change of inclination of the motor vehicle about its transverse axis.

Device for recognising a state of standstill of a motor vehicle, comprising:

• specification means for specifying at least one change of position parameter which defines a change of position of a motor vehicle which may occur in a travelling state;
• detection means for detecting an actual change of position of the motor vehicle;
• establishment means for establishing at least one actual change of position parameter which characterises the actual change of position;
• comparison means for comparing the at least one actual change of position parameter with a corresponding one of the at least one specified change of position parameters in order to determine whether the at least one actual change of position parameter characterises a travelling state for the motor vehicle;
• and
• generation means for generating a first signal which reproduces a travelling state for the motor vehicle if the at least one actual change of position parameter characterises a travelling state, or a second signal which reproduces a state of standstill for the motor vehicle if the at least one actual change of position parameter characterises a state of the motor vehicle which is not a travelling state;
• wherein the at least one change of position parameter is associated with at least one characteristic chosen from the group comprising:
• change of inclination of the motor vehicle about its longitudinal axis, change of inclination of the motor vehicle about its transverse axis, and change of inclination of the motor vehicle.

Method for recognising a state of standstill of a motor vehicle, the method comprising the steps of:

• monitoring the inclination of the motor vehicle about at least one of a longitudinal axis and a transverse axis of the motor vehicle;
• generating an actual change of position signal upon a change of inclination;
• evaluating the actual change of position signal by comparing at least one actual change of position parameter established from the actual change of position signal with at least one specified change of position parameter which defines changes of position of the motor vehicle which may occur in a travelling state;
• and
• delivering a signal which indicates whether or not the motor vehicle is at a standstill.
