The performance of a transport refrigeration system having a transport refrigeration unit powered by a diesel engine is optimized by matching a capacity output of the transport refrigeration unit to an available shaft power of the diesel engine.

A method is provided for calibrating an engine throttle position sensor operation of a refrigeration system powered by a fuel fired engine.

The invention relates to a computer-implemented method of controlling the cabin climate in a vehicle travelling on a road. A requested temperature value of a desired temperature for at least one part of the cabin is detected. An allowable temperature deviation from the requested temperature value is determined. Topographic data representative of the topography of an upcoming road segment is acquired. A flow creating device of an air-conditioning system of the vehicle is controlled based on the acquired topographic data so as to maintain the temperature within the allowable deviation. The invention also relates to a computer program, to a computer readable medium, to a control unit and to a vehicle.
