Real-Time Simulation of Trucks for Hardware-in-the-Loop Applications 942297

A real-time 3-dimensional, nonlinear simulator for the dynamical behaviour of trucks has been developed. The simulator serves as industrial test stand for examinations on different electronic control systems. This paper describes the challenging task of developing a powerful real-time simulator with hardware coupling based on parallel transputer systems.
The integration of an anti-lock braking system (ABS) as hardware-in-the-loop by means of an interface electronic device is described. The interface electronics provide the coupling of the electronic control unit (ECU). The special demands on the signals and the resulting concept for the developed electronic interface are specified. Some results from dynamic braking simulations show the quality of the simulator.
