The invention elates to a method for operating a transversal guidance system of a motor vehicle through two independent channels to perform automatic transversal guidance interventions. Through the first channel, transversal interventions are performed via a first transversal guidance actuator controlled by means of a driver-operated steering handle. Through the second channel, a vehicle system sets a target, roll angle, and a second transversal guidance actuator is controlled by a transversal guidance system that performs a transversal guidance intervention based on the roll angle. The vehicle system displays the roll angle as a notification to the driver of the transversal guidance intervention. The invention also relates to a motor vehicle configured to perform the method.

A method and controller are provided for delaying activation of autonomous emergency braking of a host vehicle, based on a determination that autonomous emergency braking is not needed because a forward vehicle in front of the host vehicle is turning out of the path of the host vehicle. The controller receives inputs from sensors arranged on the host vehicle and includes a processor for determining whether and when to activate autonomous emergency braking. The processor includes control logic that determines whether a forward vehicle is present in front of the host vehicle and whether the forward vehicle is expected to turn out of a path of the host vehicle prior to the host vehicle reaching a current position of the forward vehicle. Based on the inputs from the sensors, the control logic determines whether to delay activation of the autonomous emergency braking of the host vehicle for a time value.
