A method of controlling an automatic transmission of a motor vehicle that is situated in the force flow between a drive motor and an axle drive of a drive axle or a transfer box in which the current road inclination (αFB) is determined. To improve the shifting behavior of the transmission, during a transition between driving on a downhill stretch (2) and on level ground (4), after driving on the downhill stretch (2) and / or after the transition to a thrust operation, a recognition function for determining a downhill run-out (3) is initiated and, when the downhill run-out (3) is recognized, a shift to a higher gear during a thrust operation, i.e., a thrust upshift, is carried out before driving onto level ground (4) and / or before the transition to the traction operation.

The invention discloses a vehicle gravitational potential energy and no-load residual energy collection device, which consists of a base plate, a neutral controller, a conductor, a control panel, a level controller, a line controller, a magnet, an electromagnetic coil, a generator set, a slideway, a rotating shaft, Composed of rotor, automobile linkage device, power storage device, and horizontal air bubble; when the vehicle goes downhill and the level controller is connected for 0.8s, or when it is running in neutral, the line controller is activated to push the generator set along the slideway to drive the generator set When the power generation work is performed, the power supply wire will be automatically disconnected after 1.5s; when the car is driving on a flat road, uphill or not in neutral, the line controller will be turned from the active state to the inactive state, and the reverse power supply will be realized for 1.5s, so that The electromagnetic coil separates the small rotor from the large rotor; the device can collect and use the residual energy of the car when it is running in neutral and the gravitational potential energy when it goes downhill.

The invention discloses a roof steering follow-up air resistance retarder comprising a control system, a fixed support and at least one sub-retarder. Each sub-retarder comprises a wind resisting blade, a steering follow-up mechanism, a transmission mechanism and a locking mechanism, wherein the steering follow-up mechanism is used for driving the wind resisting blade to perpendicularly rotate in relation to a car roof and mounted on the fixed support, the transmission mechanism is used for driving the wind resisting blade to horizontally swing in relation to the car roof and mounted on the steering follow-up mechanism, the transmission mechanism comprises rotating shafts and a motor, the rotating shafts are rotatably supported on the steering follow-up mechanism, the motor is movably connected with the rotating shafts, one wind resisting blade is fixedly connected to each rotating shaft, the locking mechanism disposed on the rotating shafts is used for limiting the swing angles of the rotating shafts which horizontally swing in relation to the car roof. The roof steering follow-up air resistance retarder has the advantages that the roof steering follow-up air resistance retarder has the steering follow-up function, a car is retarded by means of air resistance, thermal load of a frictional brake during vehicle continuous braking and continuous downhill running is distributed effectively, heat fading is prevented, vehicle driving safety is improved, and wear of the frictional brake is reduced.
