Claim 8:
9. A motor vehicle having a plurality of wheels and having an electric drive for generating electric drive energy for the motor vehicle, and having a longitudinal dynamics system which uses an electric motor of the electric drive of the motor vehicle at least during an emergency braking of the motor vehicle and has a separate service brake system, and having an electronic processing circuit which is, during emergency braking of the motor vehicle, configured for:
automatically generating control signals for a total braking torque for the longitudinal dynamics system of the motor vehicle; and
generating control signals for a first braking torque at least as a proportion of the total braking torque using the electric motor of the 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; wherein a first time interval in which only the first braking torque is generated and built up to a braking torque limit value at which an anti-lock braking system of the motor vehicle is activated is shorter than a second time interval in which the first braking torque and a measurable second braking torque are generated simultaneously.
