There is a clear trend towards the all-wheel-drive chassis dynamometer, due to the increasing use of vehicle electronics, which demands realistic speeds and torques on all four wheels. The third and eminently important aspect is the need for the system to be operated rationally.
The 48“-COMPACT 4WD chassis dynamometer series has been designed to test front wheel drive, rear wheel drive and four wheel driven vehicles. It is possible to simulate vehicle weights from light cars up to light commercial vehicles. Our chassis dynamometer can be operated in the control modes road load simulation, speed control, tractive force control and acceleration control.
