METHOD AND ARRANGEMENT FOR ALLOWING SECONDARY TASKS DURING SEMI-AUTOMATED DRIVING
First Claim
1. A method for allowing secondary tasks during semi-automated driving of a road vehicle having an infotainment system which comprises one or more infotainment display units arranged in a passenger compartment thereof, and a semi-automated driver assist system including one or more sensors for acquiring data of a road ahead, the method comprising:
- determining, from at least the acquired data of the road ahead, a confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously;
determining a viewing direction of a driver of the road vehicle using a driver monitoring camera;
if the viewing direction of the driver of the road vehicle is determined to be towards the road ahead or towards an infotainment display unit of the infotainment system of the road vehicle and the confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously is determined to be above a confidence threshold, allowing autonomous control of the road vehicle by the semi-automated driver assist system; and
if, during ongoing autonomous control by the semi-automated driver assist system, the viewing direction of the driver of the road vehicle is determined not to be towards the road ahead or towards an infotainment display unit of the infotainment system of the road vehicle or the confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously is determined to be below a confidence threshold, cancelling the ongoing autonomous control by the semi-automated driver assist system and urging the driver of the road vehicle to assume control of the road vehicle.

Abstract
A method and arrangement are disclosed for allowing secondary tasks during semi-automated driving of a road vehicle having an infotainment system including one or more display units, and a semi-automated driver assist system having one or more sensors for acquiring data of a road ahead. A confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously is determined from at least acquired data of the road ahead. A viewing direction of a driver of the road vehicle is determined using a driver monitoring camera. Autonomous control is allowed if the viewing direction of the driver is determined to be towards the road ahead or towards a display unit of the infotainment system 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.

8. An arrangement for allowing secondary tasks during semi-automated driving of a road vehicle having an infotainment system including one or more infotainment display units arranged in a passenger compartment thereof, and a semi-automated driver assist system having one or more sensors for acquiring data of a road ahead, the arrangement comprising:
-
a control unit configured to determine, from at least the acquired data of the road ahead, a confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously; and a driver monitoring camera for determining a viewing direction of a driver of the road vehicle; the control unit further configured to allow autonomous control of the road vehicle by the semi-automated driver assist system if the viewing direction of the driver of the road vehicle is determined to be towards the road ahead or towards an infotainment display unit of the infotainment system of the road vehicle and the confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously is determined to be above a confidence threshold, and during ongoing autonomous control by the semi-automated driver assist system, cancel the ongoing autonomous control by the semi-automated driver assist system and urge the driver of the road vehicle to assume control of the road vehicle if the viewing direction of the driver of the road vehicle is determined not to be towards the road ahead or towards an infotainment display unit of the infotainment system of the road vehicle or the confidence of the ability of the semi-automated driver assist system to control the road vehicle autonomously is determined to be below a confidence threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
