The invention relates to a method for stabilizing a motor vehicle during emergency braking. For this purpose, direction-alternating micro-steering impulses are automatically superimposed on the steering system during the braking process, which cause a lateral micro-migration of the tire-road contact surface. The micro-steering impulses have an amplitude below that of the steering angle change consciously perceived by the driver and are designed to relieve thermally overloaded contact segments and cyclically engage adjacent, adhesive contact areas. This stabilizes the usable coefficient of friction on the tire contact patch. The procedure helps, particularly in dangerous situations during emergency braking on straight stretches or in curves, to compensate for a decrease in lateral grip and to maintain vehicle stability and steerability.
