Abstract
A method and apparatus to control the pickup on an uphill slope of an automotive vehicle provided with an automatic or robotized gearbox provide the definition of a control strategy of the gear box operation, also according to the gradient of the uphill slope, which is preferably calculated based on a longitudinal acceleration value of the automotive vehicle, and based on the altitude at which the automotive vehicle can be found, which is preferably calculated based on a detected atmospheric pressure value. In this way, it is also possible to consider the reduction in the engine torque due to the reduction in the air density with altitude.
