1. A method of on-demand energy delivery to an active suspension actuator of a vehicle, the method comprising:
detecting a wheel event of a wheel of the vehicle;
in response to the detection, supplying electric power to an electric motor/generator;
with the supplied electric power, driving a hydraulic motor/pump with the electric motor/generator to supply hydraulic fluid to the active suspension actuator, wherein the active suspension actuator is part of a hydraulic system that includes an accumulator and a valve;
applying an active force on the wheel to pull the wheel up;
accommodating hydraulic fluid, displaced by a piston rod, in the accumulator; and
controlling a flow of hydraulic fluid in the hydraulic system with the valve.
