Abstract: A method controls regenerative braking for a vehicle equipped with regenerative brakes and with a separate braking apparatus. The vehicle includes at least one first wheel and at least one second wheel. The separate braking apparatus is applied to the at least one first wheel and to the at least one second wheel. The regenerative brakes are applied to the at least one first wheel only. The method includes receiving a speed value of the first wheel and a speed value of the second wheel, estimating a value of a parameter representing a slip associated with the regenerative braking as a function of the speed value of the first wheel and as a function of the speed value of the second wheel, and forming a regenerative braking setpoint value as a function of the estimated value of the parameter representing slip associated with the regenerative braking.

Abstract: 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.
