Abstract: A system and a method are provided for controlling a foundation brake of a vehicle having at least one foundation brake device, wherein the usability of the foundation brake is limited to a predetermined total application-time of the foundation brake within a predetermined time interval.

Abstract: A system for controlling a foundation brake of a vehicle. The system includes an adaptive cruise control (ACC) device, an arrangement to detect or predict excessive use of the foundation brake and an arrangement to disengage the ACC device on detection of excessive use of the foundation brake of the vehicle.

Abstract: The invention relates to a method for measuring and estimating a brake factor in a vehicle brake system, said vehicle including a towing vehicle and a trailer having a plurality of wheel axles, wherein said method includes: initiating a controlled braking manoeuvre involving at least a first wheel axle and a second wheel axle; and obtaining values representing said brake factor for said wheel first wheel axle and said second wheel axle by a control unit which is provided with a brake adaptation function to obtain a brake balance between said towing vehicle and said trailer.

Abstract: A motor vehicle fitted with a control system for applying braking effect to foundation brakes acting on each wheel of the vehicle, when the braking effect provided by auxiliary brakes, acting on the driven wheels, is lost or significantly reduced is described. Sudden loss of auxiliary brake force can be felt as very bad drivability of the vehicle, a situation that typically occurs in case of low friction between road and tires or if the auxiliary brakes are down controlled to avoid engine stop. By use of a control system, these situations can be avoided. The control system includes a sensor, and a computer for computing and applying the braking effect to the foundation brakes to compensate for the loss of auxiliary braking force. Disclosed is also a method for applying braking effect to the foundation brakes of a motor vehicle.

Abstract: Motor vehicle with an internal combustion engine, a transmission and at least a first and a second brake device. The first brake device acts directly on at least some of the wheels of the vehicle and the second brake device acts on the driving wheels of the vehicle via the transmission and is arranged before the clutch device of the transmission. The first brake device is activated when the second brake device is in an activated state and a shifting operation is started.

Abstract: Method and apparatus for distributing brake torque between at least a first and a second brake system of a motor vehicle including at least two wheel axles and four wheels with tires, in which the first brake system acts on at least one wheel axle and in which the second brake system acts on at least one driven wheel axle and in which the distribution of brake torque between the first and the second brake system takes account of the wear of the tires and the constituent components of the brake systems.

Abstract: Method and apparatus for distributing brake torque between at least a first and a second braking device on a motor vehicle having at least two wheel pairs. The first braking device is a friction brake which acts on at least one wheel pair and the second braking device acts on at least one driven wheel pair. The distribution of brake torque between the first braking device and the second braking device takes account of brake torque required and also the maximum brake torque the first braking device and the second braking device can deliver. The distribution of brake torque takes place when the vehicle is driven with a cruise control function.
