Abstract

A computer-implemented method, system, and/or computer program product controls a driving mode of a self-driving vehicle (SDV) when a driver receives a telecommunication message on a telecommunication device. An SDV on-board computer within the SDV detects that the SDV is currently being operated in manual mode by a human driver. The SDV on-board computer detects that a telecommunication device located within the SDV is receiving a telecommunication message. In response to detecting that the telecommunication device within the SDV is receiving the telecommunication message, the SDV on-board computer transfers control of the SDV to the SDV on-board computer in order to place the SDV in autonomous mode, where the SDV is in the autonomous mode when steering, braking, throttle control, and obstacle avoidance by the SDV are all controlled by the SDV on-board computer.
