A method controls regenerative braking of a vehicle equipped with regenerative brakes and with a separate braking apparatus. The method is designed to generate a regenerative braking setpoint as a function of a braking request signal coming from a driver pedal of the vehicle, according to a first setpoint generation mode. The method includes receiving a flag signal coming from an active safety system of the vehicle, detecting value changes of the received flag signal, when the received flag signal changes value to take a value corresponding to activation of regulation by the active safety system, incrementing a counter value, and comparing the counter with a threshold. When the counter reaches the threshold, a control signal is formed to end the generation of the regenerative braking setpoint according to the first calculation mode and to impose generation of the regenerative braking setpoint according to a second calculation mode.
