At present, a number of the leading firms work on creation of an automobile autopilot. The authors of the presented article offer to complement the autopilot system with the control system of the car technical condition. The developed hardware and software complex allows working with virtual mathematical model of the gas engine of the KamAZ truck and can be recustomized under different modifications of gas and diesel engines. At the same time, by means of this complex there is an opportunity to reveal the latent defects of a control system and to reduce labor input of calibration procedures. The hardware and software allows testing electronic control units in standard and emergency operation modes of sensors and actuators, thereby providing compliance to the modern Russian and international requirements to control systems of cars.
