Switched Computation Algorithm on Automobile Power Performance

The automobile power parameters need to be estimated for consumers, even if the measured data by professional devices does not exist. Using a little data, the fitting or optimal switching methods still can support the important parameters approximately, such as power, speed, acceleration and so on. A least time switched computation of acceleration is put forward and the switched process is also demonstrated in detail. For the family used car of the examples, the power performance parameters are computed out by Mat lab programs. The whole route switched method is given out for the least time movement rule, which support a model for running car in city. All experimental data show them fit the actual situation and support consumers to consider.
