Method for controlling a driving operation of an autonomously controlled vehicle

A control system configured to control a driving operation of an autonomously controlled vehicle, the control system is connectable to a navigation system and to an angular velocity sensor configured to control the vehicle's lateral positioning along an operated road path during a loss of location situation, wherein the control system is configured to:

• obtain a signal indicative of characteristics of a road path for operation of the vehicle;
• receive a signal from the angular velocity sensor, the signal being indicative of an angular velocity the angular velocity sensor;
• determine an uncertainty parameter value of the angular velocity signal for an upcoming position of the road path ahead of the vehicle, the uncertainty parameter value being compared to a predetermined parameter threshold limit for determining an unacceptable uncertainty in lateral deviation;
• and when the uncertainty parameter value is indicated as an unacceptable uncertainty in lateral deviation of the vehicle at the upcoming position, to:
• transmit a navigation signal to the navigation system, the navigation signal being arranged to, when executed by the navigation system, cause the navigation system to autonomously operate the vehicle towards a predetermined stop position received from a positioning system of the vehicle, located prior to the upcoming position, and to arrange the vehicle in a stand-still operation when the vehicle arrives at the stop position, the predetermined stop position being a position of the road path comprising a vehicle speed reduction characteristic;
• and
• transmit a calibration signal to the sensor, the calibration signal being arranged to, when executed by the sensor, calibrate the sensor when the vehicle is arranged in the stand-still operation.
