Description

technical field [0001] The invention relates to the technical field of active anti-rollover control of automobiles, in particular to a differential braking / drive coordinated anti-rollover control system and a control method thereof. Background technique [0002] Distributed drive electric vehicles are one of the high-tech carriers that integrate the advantages of zero emissions, efficient transmission, and flexible control under the development trend of vehicle electrification. However, as the speed of vehicles increases, the incidence of rollover accidents will continue to rise. Distributed drive electric vehicles also face this complex problem of dynamic instability control. [0003] Compared with passive anti-rollover measures, active anti-rollover control technology has a more ideal anti-rollover control effect. Among them, differential braking technology anti-rollover control technology is a typical vehicle active anti-rollover control technology. Control Technology. ...
