Abstract
A method and device for controlled damping of a vehicle stores a set of controller parameters R1 to Rn for controlling the damping of the unloaded vehicle as a function of the dynamic driving situation thereof 1 to n, detect a loading condition b of the vehicle, adapt the set of controller parameters R1 to Rn as a function of the detected loading condition b to a set of controlled parameters R1b to Rnb, and dams the vehicle as a function of the set of controller parameters R1b to Rnb as a function of the dynamic driving situation thereon 1 to n.
Claims14
A device for controlled damping of a vehicle, the device comprising:
- a storage unit for storing a set of controller parameters R1 to Rn for controlling damping of an unloaded vehicle as a function of a dynamic driving situation 1 to n of the vehicle;
- a detecting unit for detecting a loading condition b of the vehicle;
- an adaptation unit for adapting the set of controller parameters R1 to Rn as a function of the detected loading condition b to a set of controller parameters R1b to Rnb;
- and
- a damper for damping the vehicle as a function of the set of controller parameters R1b to Rnb as a function of the dynamic driving situation 1 to n, wherein:
- the storage unit adjusts for storing at least two sets of controller parameters R1k1 to Rnk1 and R1k2 to Rnk2 for different comfort modes k1, k2 of the unloaded vehicle,
- the storage unit adjusts either for storing for each set a set of controller parameters R1Bk1 to RnBk1 and R1Bk2 to RnBk2 for a fully loaded vehicle or a single set of controller parameters R1B to RnB for the fully loaded vehicle,
- the adaptation unit adjusts for determining the set of controller parameters R1b to Rnb by a driver pre-selection of one of a plurality of different comfort modes and a mathematical interpolation between the thereby selected set of controller parameters for the unloaded vehicle and the pertaining or single set of controller parameters for the fully loaded vehicle.
A method for controlled damping of a vehicle, the method comprising the acts of:
- storing a set of controller parameters R1 to Rn for controlling damping of an unloaded vehicle as a function of the dynamic driving situation 1 to n of the vehicle;
- detecting a loading condition b of the vehicle;
- adapting the set of controller parameters R1 to Rn as a function of the detected loading condition b to a set of controller parameters R1b to Rnb;
- and
- damping the vehicle as a function of the set of controller parameters R1b to Rnb as a function of the dynamic driving situation 1 to n of the vehicle;
- wherein, during the storing act, at least two sets of controller parameters R1k1 to Rnk1 and R1k2 to Rnk2 for different comfort modes k1, k2 of the unloaded vehicle, and either, for each set, a set of controller parameters R1Bk1 to RnBk1 and R1Bk2 to RnBk2 for the fully loaded vehicle or a single set of controller parameters R1B to RnB for the fully loaded vehicle, are stored;
- and
- wherein, during the adapting act, the set of controller parameters R1b to Rnb is determined by a driver pre-selection of one of a plurality of different comfort modes and a mathematical interpolation between the thereby selected set of controller parameters for the unloaded vehicle and the pertaining or single set of controller parameters for the fully loaded vehicle.
