Method for determining the total deceleration values of a commercial vehicle achievable by actuation of wheel brakes, brake system for carrying out the method and utility vehicle therewith

摘要

The invention relates to a method for determining the total deceleration values (b, b) achievable by actuation of wheel brakes of a commercial vehicle (6) or a vehicle combination (24) with a plurality of axles (7, 8). The invention also relates to a brake system for carrying out the method and In order to determine the currently achievable total deceleration values (b, b) for deceleration of a commercial vehicle or a vehicle combination with several axles, it is provided according to the invention that for the implementation of a deceleration request (FIG. 20) at partial braking (27) a braking force distribution (26) with unequal on brake units (1, 2, 3, 4) with the wheel brakes (10) one or more axes (7, 8) distributed braking forces (F, F, F, F ), wherein one of the brake units (1, 2, 3, 4) is selected in each case and via this selected brake a greater braking force (F) than the other brake units (1, 3, 4), wherein a current deceleration b of the commercial vehicle (6) or the vehicle combination (24) is measured or determined and as the corresponding partial delay value ( b, b, b, b) is assigned to the respectively selected brake unit (29) and stored. The achievable total deceleration values (b, b) are determined as the sum (31) of the partial deceleration values (b, b, b, b) of the brake units (1, 2, 3, 4).
