A method of and an apparatus for controlling a brake system in a heavy-duty vehicle provide for continuously measuring parameters which are characteristics of the state of the vehicle, such as the velocity of the vehicle, the inclination of the roadway, the axle load, and the transverse acceleration. Furthermore, the braking capability is being monitored continuously. To that end the temperature of the brakes, their condition of wear, the state of a compressed air reservoir, and the tire pressure are measured. For any given state of the vehicle and brakes it is determined whether or not the stopping distance to be expected will be longer than a predetermined rated stopping distance. If that is so, the driver is warned and/or a reduction of the travelling speed is initiated automatically.

A method of monitoring a brake system in a heavy-duty vehicle, the method comprising the steps of measuring the velocity (V) of the vehicle, measuring the inclination (N) of the roadway, measuring the axle load (A), measuring the transverse acceleration (Q) of the vehicle, measuring the temperature (T) of the brakes, measuring the condition of wear (S) of the brakes, measuring the condition (P) of a brake pressure source, and measuring the tire pressure (PR) of the tires of the vehicle, and determining on the basis of said measured velocity (V), inclination (N), axle load (A), transverse acceleration (Q), temperature (T), wear (S), condition (P) of a brake pressure source, and tire pressure (PR), a stopping distance (Xist) to be expected, comparing said stopping distance (Xist) to be expected with a maximum permissible stopping distance (Xsoll), and generating a warning signal if said stopping distance (Xist) to be expected exceeds said maximum permissible stopping distance (Xsoll).
