Abstract: The invention relates to a method for assembling a motor vehicle heating, ventilation and/or air conditioning device, comprising a step of moving at least one part by a manipulator (I) provided with gripping means (2), the gripping means (2) comprising at least one first finger (3) delimiting a triangular shape, said part comprising an element of shape complementary to the trian-gular shape of the finger of the manipulator, termed counter shape, so that, during the movement step, the manipulator (I) grasps the part using the gripping means (2), the counter shape of the part en-gaging with the triangular shape of the finger (3).

Abstract: A method for accelerating the warming-up of a power unit of a vehicle including an internal combustion engine, the unit needing to undergo a test and/or maintenance operation during which the vehicle remains stationary with its engine running, the unit needing to have achieved a minimum operating temperature prior to the test and/or the operation, the unit including a fuel injection system with a high-pressure pump supplying pressurized fuel to one or more injectors, the pressurizing of the fuel by the pump being controlled according to a combustion configuration that requires a nominal pressure value dependent on operating parameters including an engine speed and engine torque, the method including a step of warming up the unit by maintaining a greatly accelerated idling speed, which is effected at a modified pressure value higher than the nominal pressure value.
