— The transition from LKAS off to LKAS on can be performed by the driver or automatically, e.g. after the ignition is switched on and no system failure has occurred. The transition from LKAS on to LKAS off can be performed by the driver or automatically, for Instance after the Ignition Is switched off ora system failure has occurred.
— LKAS shall be operational for speeds between vmln and ‘max. vmin = 20 rn/s. vmax = 30 rn/s. or the maximum possible vehicle speed, whichever is less. It is allowed to be operational in a wider speed range.
— In LKAS stand-by state, the system shall evaluate the activation criteria. LKAS shall not perform any lane keeping actions. One of the activation criteria shall be that the system has determined the position of thc vehicle within the lane relative to the visible lane markings of its own lane. It Is up to the manufacturer to decide whether it is necessary to detect one or both visible lane markings of the own lane. Other criteria to be selected by the manufacturer can be the type of the lane marking (e.g. solid or dashed), a minimum vehicle speed, driver actions, steering angle, and other vehicle conditions. If all of the selected activation criteria are met, the system shall transition from LKAS stand-by to L.KAS active state. This transition can be done automatically or by a driver confirmation.
