The invention discloses a parallel starting control method and system for a hybrid vehicle and the hybrid vehicle. The parallel starting control method for the hybrid power vehicle comprises the following steps that the current working conditions of a clutch and a gearbox of the hybrid power vehicle, the engine request torque of the hybrid power vehicle and the starting mode of the hybrid power vehicle are obtained; according to the current working conditions of the clutch and the gearbox, whether the hybrid power vehicle meets the overheating protection condition or not is judged, and the starting basic torque is determined according to the judgment result and the engine request torque; determining a starting clutch request torque based on the starting basic torque according to a starting mode of the hybrid vehicle; and performing starting control on the clutch according to the starting clutch request torque. According to the scheme, the starting safety, responsiveness and dynamic property of the hybrid power vehicle can be improved.
