Übersetzung für "Anfahren am berg" in Englisch

The hugely powerful motor is especially gutsy on hill starts.

This is comparable to the first gear of a car when starting on a hill.

The brake pressure booster is controlled automatically by the electromagnetic valve so as to facilitate starting up a hill.

The advantage of the invention is the electrically regulated braking, which makes one-handed steering unnecessary when starting up on a hill, as well as the automatic tightening of the hand brake upon parking, which prevents the vehicle from unintentionally rolling away.

Another advantage is that if the apparatus is intact, starting the car on a hill is easier, because one-handed steering is unnecessary.

If the road speed signal is not available because the road-speed transducer is defective, then the same function blocks are available in the right branch of the flowchart; however, with the exception that in lieu of road speed, the engine speed n is limited and with the guideline that the waiting time tdefmax which is here provided is in this case selected to be greater so as to make possible a starting of the vehicle on a hill without difficulty.

Such a starting of the vehicle on a hill can only be detected if the road-speed transducer is operational; whereas, if reliance is placed only on the engine speed signal n, the maximum engine speed nmax can be exceeded when pressing the accelerator pedal excessively at standstill.

The method of claim 1, wherein, in the case of a defective road-speed transducer (FGG), the additional time delay in the form of a waiting time (tdefmax) is selected to be greater than the time delay for a functionally operational road-speed transducer in order to make possible a trouble-free start up a hill.

Problems occur particularly when starting on a hill or on a steeply sloping road because it is difficult or impossible for the vehicle operator to simultaneously release the foot brake pedal and operate the accelerator pedal and thus provide an engine torque necessary for the corresponding starting operation.

During emergency running the variable ratio change makes possible, for example, a safe starting on a mountain and an improved drive-ability with a high final speed.

The process according to the invention represents an extremely simple and effective measure for ensuring a vehicle start, particularly on a hill, without any problems.

With the aid of the emergency hydraulic control, on vehicle starting a startup gear ratio in the low range is to be set, for instance to enable starting up on an uphill slope or when leaving an underground garage.

Such a metered operation of the vehicle brake according to the invention can also be used for facilitating hill climbing in that initially a rolling back of the vehicle is prevented by the already described blocking function of the brake (so-called “hillholder” function) and that upon starting, the brake is released slowly and controlled in a manner corresponding to the velocity increase of the vehicle.

The advantages of the invention are, above all, the improvement which it makes possible in comfort, safety and economy when starting a motor vehicle under a very wide range of ambient conditions, such as when starting on an incline, when maneuvering and when performing parking maneuvers.

The performance-oriented characteristic curves also constitute a good possible way of providing enjoyment in driving or drivability, for example in the case of a racing start or when starting on an incline.

Excessive generation of heat in the clutch, which is detected, for example, by means of a thermal model calculation in the IPM controller 16, can lead to a reduction in the engine setpoint rotational speed ne,nom during persistent starting operations (for example permanent starting at an incline).

In some situations, such as hill starts, it will be even safer to ride than a bicycle, because you can accelerate more safely and quickly to a stable riding speed.

The set-off assistant Hill Start Control is likewise a standard feature in all three models, enabling convenient set-off on slopes.

For example, the brake can be released in an automated manner for a “hill start”, so that the driver does not have to operate the brake in addition to the interplay of the accelerator and the clutch.

However, especially when starting up with severe slip in the clutch, i.e., for example, when starting up on a hill, wet clutches of this type are often no longer capable of removing to a sufficient extent the heat produced in the region of the friction surface arrangements bearing frictionally against one another, it thus being possible, at least in local regions, for thermal overloading to occur.

In order to provide an improved cooling effect with the friction clutch arrangement 22 particularly in the event of temporary, heavy loads, such as, for example, a sharp acceleration when starting up or when starting up on a hill, since the cooling effect provided by the exchange of fluid is comparatively slow, according to the present invention a circulation of fluid which is combined with the fluid exchange flow is built up within the housing arrangement 12 .

For this reason, in this category of vehicle it has previously hardly been possible to fit the electric parking brake and provide the gain in comfort associated therewith, for example during a hill start.

As a result, in addition to simple maneuvers complex maneuvers are also possible, such as starting up on a hill on snow as well as ABS braking operations.

Because the limit value for the root mean square current reaches the limit thereof within a short period of time at low temperatures or when starting to ascend a hill, for example already after 10 seconds, an aim of the invention is increase the limit values without having to modify the warranted battery service life, which, for example, is set at 15 years.

For example, it is possible when using the differential in the motor vehicle, that a higher torque will be transmitted specifically to one of the wheels when starting up or stopping on the mountain or when driving over an obstacle such as a curb or similar in order to overcome the obstacle or to compensate for a not fully horizontal roadway, which turn wheels of the motor vehicle and thus the drive axles however with identical or nearly identical rotational speed.
