The invention discloses a friction plate abrasion monitoring and parking braking method and system and a vehicle. The method comprises the steps that a theoretical PV curve is obtained; acquiring a real-time PV curve; the theoretical PV curve and the real-time PV curve are compared and calculated to obtain the abrasion loss of the friction plate; a parking gradient is obtained; according to the method, the thickness change, namely the abrasion loss of the friction plate, of the friction plate is obtained through comparison and calculation of the theoretical PV curve and the real-time PV curve, the parking braking force is adjusted according to the abrasion loss of the friction plate and the parking gradient, and the parking braking force is adjusted according to the parking gradient and the abrasion loss of the friction plate. When the abrasion degree of the friction plate is serious, a driver is prompted and parking braking force is adjusted, the slope sliding risk is prevented, parking safety is guaranteed, the abrasion degree of the friction plate can be monitored in real time, an abrasion alarm can be omitted, and cost is reduced.
