TEST BENCH FOR A MOTOR VEHICLE HYBRID DRIVE GROUP

摘要

The subject of the present invention is a test bench for a hybrid powertrain making it possible to reduce the operating and calibration costs of the pollution control functions. According to the invention, the test bench comprises only the first drive machine (10) of said first and second drive machines and control means comprising means for determining (15) a first torque setpoint (CS1) of the first drive machine (10) equipping the test bench, said first setpoint (CS1) being calculated as a function of a second virtual torque setpoint (CS2) of the second drive machine and of a third virtual torque setpoint (CS3) ) of the first driving machine (10), said third setpoint (CS3) being calculated for a model of the vehicle comprising a powertrain without the second driving machine for the execution of said driving cycle. The invention also relates to a method of piloting the test bench. Figure 2
