Driving system with automated lateral guidance which can be deactivated by a steering intervention, and method for deactivating automated lateral guidance

A driving system for automated driving with at least automated lateral guidance for a motor vehicle with a steering wheel comprising:

• an electronic control unit configured to:
• deactivate the automated lateral guidance as a reaction to a manual steering intervention starting from a driving state with activated automated lateral guidance;
• and
• in the driving state with deactivated automated lateral guidance:
• determine a virtual vehicle guiding by automated lateral guidance,
• determine a deviation variable which is characteristic of a deviation of manual vehicle driving with respect to the virtual vehicle guiding determined by the automated lateral guidance, and
• in case of the determination that there is no longer any driver-side steering wheel contact:
• activate the automated lateral guidance again if the deviation variable is less than or equal to a third deviation threshold value.

A method for deactivating automated lateral guidance of a driving system for automated driving for a motor vehicle with a steering wheel comprising:

• starting from a driving state with activated automated lateral guidance, deactivating the automated lateral guidance in response to manual steering intervention;
• and during a driving state with deactivated automated lateral guidance:
• determining a virtual vehicle guiding by automated lateral guidance,
• determining a deviation variable which is characteristic of a deviation of manual vehicle driving with respect to the virtual vehicle guiding determined by the automated lateral guidance,
• determining the deviation variable is less than or equal to a second deviation threshold value, and
• activating the automated lateral guidance again based on the determination.
