In order to meet the rapid response of the automobile brake-by-wire system to the control motor, this paper proposes an improved super-twisting sliding mode algorithm to realize the accurate control of the brake master cylinder pressure. The paper firstly analyzes the convergence and stability of classical super-twisting sliding mode algorithm, then proposes an improved strategy of super-twisting sliding mode algorithm to solve the problem of slow convergence at the position where the sliding surface is far from the equilibrium point. The stability of the proposed algorithm is proved by theoretical analysis of Lyapunov equation. Finally, the effectiveness of the algorithm is verified by simulation and bench test of brake-by-wire system. The results show that the improved super-twisting sliding mode algorithm improves the convergence speed of the pressure overshoot of the brake-by-wire system by 3.87%, and the steady-state error is controlled within 2%, which improves the control robustness and demonstrates good control performance.
