Elektronické systémy řízení stability podvozku pro vozidla s elektrickým pohonem a IWD/IWB

Abstract

The work deals with an analysis and design of a new solution for redundant lateral steering of vehicles by using selective distribution of driving and braking torque of individual wheels. The paper describes the analysis of currently used active driving stability systems, as well as some limiting factors for their functions. In the introduction, the motivation for the emergence of a system of redundant lateral control is described and the state of art of established approaches to the solution of the mentioned system is described. The description of the experimental vehicle Democar 2, which serves as a platform for the development of automotive electronic systems, captures the IWD, IWB, SbW systems and the traction battery and vehicle power supply network system in more detail. The next chapter involves the simulation model of the vehicle, which is used to research and optimize the control algorithms of the IWB and IWD systems and their cooperation. The following part deals with description of the proposed redundant lateral control system. The last part contains simulated and real driving tests, capturing the operation of the system.
