METHOD AND ARRANGEMENT FOR CONTROLLING BRAKES IN A VEHICLE OR A VEHICLE COMBINATION
First Claim
1. A method for controlling the brakes of a vehicle or a vehicle combination comprising at least two wheel axles and each axle having two or more wheels with tires, said method comprising:
- generating a signal related to the air pressure in at least one of the tires on the vehicle and said signal being sent to a control unit in the vehicle;
detecting an abnormal drop in pressure in at least one of the tires based on said generated signal; and
reducing the braking function produced by braking devices associated with the axle on which the tire is mounted that has been detected as experiencing an abnormal pressure drop.

Abstract
Method and an arrangement for controlling the driving brakes of a vehicle or a vehicle combination with at least two wheel axles, each axle having two or more wheels with tires. The arrangement includes a control unit (1, 21) for controlling the brakes and a signal generator for generating a signal proportional to the air pressure in one or several tires. The control unit (1, 21) is arranged, upon the reception of the signal, to detect an abnormal drop in pressure and to reduce the braking function for all the braking devices (6, 7; 8, 9; 26, 27; 28, 29) on the axle (10, 11; 30, 31) on which an abnormal drop in pressure has been detected in any one tire.

10. An arrangement for controlling the driving brakes of a vehicle or a vehicle combination comprising at least two wheel axles, each axle having two or more wheels with tires, said arrangement comprising:
-
a control unit (1, 21) that controls the driving brakes and means for generating a signal proportional to the air pressure in at least one tire, said control unit (1,21) being configured, upon the reception of said signal, to detect whether there has been an abnormal drop in tire pressure; and
said control unit (1, 21) being further configured to reduce the braking function of braking devices (6, 7;
8, 9;
26, 27;
28, 29) associated with the axle (10, 11;
30, 31) with which the tire experiencing an abnormal drop in pressure is associated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
