The actual methods to provide an average consumption of a certified vehicle are the standard driving test. As different standards exist according to the country, they have in common to test vehicle on laboratory on test benches. The use of test benches is motivated since it allows to simulate the road conditions in a repeatable way and under specific conditions providing consistency of the measurement. The emulation of the road conditions has to be transferred to the bench were the car can spend its power. The use of chassis dynamometer allows to produce a resistive torque to the car’s wheel in accordance with the road load simulation model. This master’s thesis aims in his turn to assess car consumption on driving test but specifically for a 1:10 RC electric car. This car has basically been built for an endurance race. Given that it is a specific vehicle, no standards are defined, and this thesis proposed a simplified driving cycle which give specifications to design an adapted chassis dynamometer car allowing to emulate a road load conditions. The use of an industrial PLC computer allows the automation of the tests as the same time as the assessment of the mechanical and electrical power. The presented results report the chassis dynamometer design under PTC CREO, assembly and test. The simulation of the road load adapted to a 1:10 car along a driving cycle. The acquisition of the motor rotational speed, battery voltage, under TwinCAT PLC using the I/O communication EtherCAT. Further, method of system identification has been tested with Simulink toolbox for PMSM/converter speed control.
