System and method pertaining to braking of a vehicle combination which comprises a tractor vehicle with a towed vehicle

A system for braking a vehicle combination,

• wherein:
• said vehicle combination comprises a tractor vehicle coupled to a towed vehicle,
• the system comprises a first control unit, a transfer device, and a registering device,
• both of said tractor vehicle and said towed vehicle are configured to be braked;
• said tractor vehicle has said first control unit which comprises a function for regulation of a coupling force between said tractor vehicle and said owed vehicle,
• said regulation of coupling force comprises using adaptation data associated with a braking process and said towed vehicle bears a unique ID specification;
• said transfer device is configured for transferring said unique ID specification from said towed vehicle to said tractor vehicle;
• and
• said registering device is configured so that during said braking process, said registering device registers said adaptation data together with said unique ID specification of said towed vehicle.

A method of braking a vehicle combination;

• the method comprising the steps of:
• transferring from a towed vehicle, included in said vehicle combination, an ID specification of said towed vehicle to a tractor vehicle, included in said vehicle combination, said towed vehicle being coupled to said tractor vehicle;
• beginning a braking process of said vehicle combination;
• and
• during said braking process, registering adaptation data associated with said braking process together with said ID specification of said towed vehicle;
• wherein said tractor vehicle is provided with a first control unit comprising a function for regulation of coupling force between said tractor vehicle and said towed vehicle that are coupled together, said regulation of said coupling force comprises using said adaptation data associated with said braking process, and said regulation of coupling force is effected by continuously controlling a distribution of braking force between brake systems of said tractor vehicle and said towed vehicle,
• the method further comprising the step of:
• regulating said coupling force between said tractor vehicle and said towed vehicle using said adaptation data which has already been registered.

A tractor vehicle for use in a vehicle combination, wherein:

• said tractor vehicle is configured to be coupled to a towed vehicle;
• both of said tractor vehicle and said towed vehicle, which is coupled to said tractor vehicle, are configured to be braked;
• said tractor vehicle has a first control unit configured to perform a function for regulation and distribution of a coupling force between said tractor vehicle and said towed vehicle;
• said first control unit is configured to regulate said coupling force by using adaptation data for said braking, said adaptation data being in said tractor vehicle;
• said tractor vehicle is configured to receive an ID specification of said towed vehicle which is coupled to said tractor vehicle;
• a registering device is configured so that during said braking, said registering device registers said adaptation data together with said ID specification of said towed vehicle;
• and
• said regulation of coupling force is effected by continuously controlling a distribution of braking force between brake systems of said tractor vehicle and said towed vehicle.
