摘要： The invention relates to a method of braking a vehicle (100), particularly a towing vehicle and/or a towed vehicle of a truck, having at least three axles (10, 20, 30, 40, 50, 60, 70), wherein each axle (10, 20, 30, 40, 50, 60, 70) has at least one left wheel (101, 201, 301, 401, 501, 601, 701) and one right wheel (10r, 20r, 30r, 40r, 50r, 60r, 70r), wherein at least two selected axles (30, 40, 50, 60, 70) and/or left and right wheels (301, 401, 501, 601, 701; 30r, 40r, 50r, 60r, 70r) connected to the at least two selected axles (30, 40, 50, 60, 70) are steerable, and wherein, for exerting a brake force, the left and right wheels (301, 401, 501, 601, 701; 30r, 40r, 50r, 60r, 70r) of at least one of two selected axles (30, 40, 50, 60, 70) are turned compared to a straight direction (80) to counteract cornering of the vehicle (100). The left and right wheels (301, 401, 501, 601, 701; 30r, 40r, 50r, 60r, 70r) associated with the same one of the two selected axles (30, 40, 50, 60, 70) are turned in the same direction (80r, 801).

摘要： A method is provided for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel, wherein the vehicle includes a steering arrangement including a manually operated steering device, at least one pair of ground engaging members and a mechanical interconnection between the steering device and the ground engaging members. The method includes detecting a steering angle and determining a desired steering device guiding force based on the detected steering angle, providing the driver with the desired steering feel based on the desired steering device guiding force, and detecting the steering angle in a position at a ground engaging member side of an elastic steering force transmitting element in the steering arrangement.

摘要： A method for estimating the friction coefficient between the stator and the rotor in a breaking device, comprising the following method steps: measurement of the temperature of the braking device, establishment of the friction coefficient by calculating the relationship between a measure of thermal energy generated by the rotor and the stator during a time interval and a measure of braking energy absorbed by the rotor and the stator during the same time interval, in which said generated thermal energy is calculated from a function of said measured temperature. The method is preferably used in calculating a correction factor for trailer compensation.
