This paper addresses a security control issue of connected vehicle systems subject to denial-of-service (DoS) attacks. To deal with the bandwidth constraint, a novel dynamic event-triggered mechanism (DETM) is proposed. Compared with static ETMs, attack intensity is introduced into the design of triggering parameters, which strikes a better balance between the data releasing amount and system performance. To withstand the negative impact of DoS attacks, an extended tracking error model is constructed, which integrates a modified bidirectional information topology, intermittent DoS attacks, DETM into a unified scheme. By using a piecewise Lyapunov function, a co-design method of controllers and communication parameters is developed. Different from string stability or asymptotic stability analysis methods, finite-time boundedness of the concerned system is investigated to provide an evaluation of system performance with respect to time. Finally, simulation results verify the effectiveness of the proposed methods.
