Abstract: Method for controlling speed surge of an internal combustion engine of a moving vehicle during a ratio change of a manual gearbox, the vehicle including an engine control unit with a transient progressive torque reduction phase activated when the driver requests zero torque or when the foot is raised, the engine control unit: detects the raised foot and activates the transient progressive torque reduction phase; records engine speed and determines the gearbox ratio engaged when the foot is raised; determines, a maximum permissible engine speed (Nmax) which is greater than the recorded speed (Nlvp) of the raised foot, in accordance with the engine speed recorded and the engaged gearbox ratio; monitors the current speed (Nc) so that if Nc>Nmax, a stop is initiated with immediate effect of the transient progressive torque reduction phase, an if Nc?Nmax, the transient progressive torque reduction phase is maintained.
