The invention relates to a very simple method of controlling emergency braking of a rail vehicle comprising at least one motor axle provided with motor axle friction brake means and a reversible electric rotating machine and one trailer axle provided with trailer axle friction brake means, the method comprising the following steps: - applying a constant dynamic brake force to the motor axle with the reversible electric rotating machine, - applying a complementary friction brake force to the motor axle with the motor axle friction brake means, - applying an emergency braking force to the trailer axle with the trailer axle friction brake means, such that the sum of the constant dynamic brake force and the complementary friction brake force equals the emergency braking force.
