This research aims at improving longitudinal control of tele-operated vehicle under severe communication delay, which often causes remote operator to make wrong decision. Inspired from the adaptive cruise control (ACC) system equipped on commercial vehicles, a new cooperative control architecture in which the remote drivers’ command is involved is proposed. In additional, the ACC system is implemented using sliding mode control method and the closed-loop stability and string stability are also investigated. Simulation results show that the proposed controller performs well in many scenarios, including car following, stop-and-go and tele-operated driving.
