Abstract
The invention relates to a method for decelerating a motor vehicle during emergency braking, wherein the entire emergency braking is automatically carried out by a longitudinal dynamics system of the motor vehicle, wherein, for emergency braking, a total braking torque is automatically generated by the longitudinal dynamics system of the motor vehicle, and, for this purpose, a first braking torque is generated at least as a proportion of the total braking torque by an electric motor of an electric drive of the motor vehicle in a time interval beginning with the automatic initiation of the emergency braking and shorter than the total duration of the emergency braking, in which time interval the total braking torque cannot yet be generated solely by a service brake system of the longitudinal dynamics system. The invention also relates to a motor vehicle.
