Test procedure for hybrid vehicle consumption measurement

In the course of the SUVA project, hybrid electric vehicles have been investigated, conducting longitudinal simulations and vehicle tests. One important emphasis in the simulations and measurements has been the determination of energy consumption. Since all hybrid electric vehicles in the project operate using a charge-sustaining control strategy and do not have the possibility of external recharging, only fuel is consumed.

In order to quantify the state of charge of the battery together with the fuel consumption, the procedure proposes a state of charge regression, which shows the consumption result in the hypothetic case that the state of charge in the beginning of the test would be identical like at the end of the test.

The procedure will be necessary in the future in order to execute the standard consumption measurement with hybrid vehicles similar to vehicles with conventional driveline.

Any manufacturer and test organisation will have to install similar procedures in order to enable energy consumption measurements on hybrid driveline systems.
