摘要：
A method for controlling the cruising speed of a hybrid or electric propulsion vehicle comprises detecting a forward travel speed (vn) of the vehicle (100), identifying a downhill forward travel condition of the vehicle (100), activating a control of the downhill cruising speed following said identification of said downhill forward travel condition, determining a reference speed (vref) for the vehicle (100) and calculating a charging current for the battery pack (3) generated by the electric motor (2) as a function of a deviation between said reference speed (vref) and the detected forward travel speed (vn) of the vehicle. The step of identifying a downhill forward travel condition of the vehicle (100) comprises calculating a parameter representative of said downhill condition as a function of the detected forward travel speed and the motor current.
