1. A computer-implemented method of controlling operation of one or more subsystems of a plurality of subsystems of a vehicle to improve performance, the method comprising:

  • storing at a vehicle, historic vehicle state information specifying a plurality of performance values associated with a plurality of subsystems of the vehicle at a plurality of time points, including a current time point;

    receiving at the vehicle, other state information specifying a plurality of performance values associated with a second system;

    generating a forward-looking model, the forward-looking model specifying a relative weighting of the plurality of subsystems of the vehicle being associated with improved performance;

    determining a performance value associated with the one or more subsystems of the plurality of subsystems of the vehicle based on the historic vehicle state information, the other state information and the forward-looking model; and

    generating and sending a signal based on the performance value.
