The invention relates to the technical field of electric power steering, and discloses an EPS inertia compensation control method and device, a vehicle, a medium and a product. To-be-calculated inertia compensation torque signals are divided into a low-frequency band, a middle-frequency band and a high-frequency band; calculating an inertia compensation signal component in a low-frequency band; calculating a damping reduction signal component for reducing the damping torque in the middle frequency band; calculating a noise cancellation signal component for eliminating high-frequency noise in a high-frequency band; superposing the inertia compensation signal component, the damping reduction signal component and the noise cancellation signal component to obtain an inertia compensation torque signal; and the power-assisted motor is controlled through the inertia compensation torque signal. According to the invention, the time delay caused by inertia is compensated, quick response can be provided during steering correction or quick steering wheel turning and when the motor operates in a medium frequency band, meanwhile, disturbance can be inhibited when the motor is interfered by high-frequency noise, and the accuracy of an inertia compensation signal is integrally improved.
