Abstract
A vehicle and method for controlling a vehicle having a traction battery and an internal combustion engine include adapting a power limitation of the internal combustion engine by sensing a currently supplied power level of the internal combustion engine and a current velocity of the vehicle, sensing an ambient temperature of the vehicle and determining an associated ambient-temperature-related weighting factor, sensing an ambient air pressure and determining an associated air-pressure-related weighting factor, determining a thermal load indicator as a function of a ratio of the sensed currently supplied power and the sensed current velocity as well as of the ambient-temperature-related weighting factor, the air-pressure-related weighting factor, and a vehicle-bodywork-related weighting factor, and limiting a maximum supplied power level of the internal combustion engine as a function of the determined thermal load indicator.
