METHOD AND ARRANGEMENT FOR ALLOWING SECONDARY TASKS DURING SEMI-AUTOMATED DRIVING

This disclosure relates to a method and arrangement for allowing secondary tasks during semi-automated driving of a road vehicle (1) having an infotainment system (2) comprising one or more display units (3), and a semi-automated driver assist system (5) comprising one or more sensors (6) for acquiring data of a road ahead. A confidence of the ability of the semi-automated driver assist system (5) to control the road vehicle (1) autonomously is determined from at least the acquired data of the road ahead. A viewing direction of a driver of the road vehicle (1) is determined using a driver monitoring camera (7). Autonomous control is allowed if the viewing direction of the driver is determined to be towards the road ahead or towards a display unit (3) of the infotainment system (2) and the confidence is determined to be above a confidence threshold, otherwise any ongoing autonomous control is cancelled and the driver urged to assume control of the road vehicle (1).
