20090203498 | SYSTEM FOR CONTROLLING A FOUNDATION BRAKE OF A VEHICLE - 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. | 08-13-2009 |
20100211279 | METHOD AND ARRANGEMENT FOR MEASURING AND ESTIMATING A BRAKE FACTOR IN A VEHICLE BRAKE SYSTEM - 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. The method furthermore includes: braking, in a forced manner, said first wheel axle when retardation of said vehicle is requested; estimating the brake factor for said first wheel axle by determining the brake pressure and braking torque for said first wheel axle; providing a transition phase after which said second wheel axle is braked, in a forced manner, and estimating the brake factor for said second wheel axle by determining the brake pressure and braking torque for said second wheel axle. An arrangement for measuring and estimating the brake factor in a vehicle brake system is also disclosed. | 08-19-2010 |
20100280729 | SYSTEM AND METHOD FOR CONTROLLING A FOUNDATION BRAKE - 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. | 11-04-2010 |

20100033008 | RETARDER SLIP CONTROL - 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. | 02-11-2010 |
