Abstract: The present invention relates to a method, system, vehicle, and computer program product for determining time data relating to a non-combustion outlet process of a fuel gas from a gas tank associated with a vehicle. The method comprises providing a model for the state of fuel gas in the gas tank. The method further comprises determining time data relating to the outlet process of the fuel gas based on the model.

Abstract: A method for controlling a motor vehicle, comprising: retrieving road gradient data relating to an expected travelling route of the motor vehicle; based on at least the retrieved road gradient data and on a motor vehicle mass, simulating a required value of a braking power related variable, which required value is needed to prevent a vehicle speed from increasing above a preset desired vehicle speed in an upcoming downhill slope; determining an available value of the braking power related variable of at least one auxiliary brake of the motor vehicle; and based on the determined available value and the simulated required value of the braking power related variable, controlling the vehicle speed and/or at least one brake actuator of the motor vehicle such that the vehicle speed does not increase above the preset desired vehicle speed in the upcoming downhill slope.
