A method for controlling the speed of a vehicle comprising: receiving a vehicle speed set-point; obtaining a current vehicle speed; and determining a vehicle speed error (e.g. difference) between the set point and current speed; the error is positive when the set point is higher than the current speed and negative when the opposite; when positive the vehicle transmission ratio is increased to accelerate the current vehicle speed towards the set point increasing the engine load; when negative the transmission ratio is reduced to remove engine load and decelerate the current speed towards the set point.
