The invention discloses a reliable control method for a singular pulse vehicle suspension under actuator faults and random time lag. The reliable control method comprises the following steps that firstly, a singular hybrid active vehicle suspension system which comprises vehicle suspension sprung mass and unsprung mass acceleration and has pulse disturbance is established; and 2, establishing a modal-dependent reliable controller based on the actuator fault and Bernoulli random time lag, and realizing robust stabilization of the singular hybrid active vehicle suspension system with the actuator fault, transmission time lag and pulse disturbance. The method has the advantages that according to the established singular hybrid active vehicle suspension system with pulse disturbance, acceleration of sprung mass and unsprung mass is considered, and measurable real-time signals of the system are fully utilized; through a parallel distributed compensation method, a modal dependent feedback reliable controller based on actuator faults and Bernoulli random time lag is designed, and it is guaranteed that the vehicle suspension system meets the H-infinity performance when subjected to actuator faults, transmission time lag and pulse disturbance.
