摘要： The present disclosure relates to a method for controlling a powertrain system (305) of a heavy-duty vehicle (100), said powertrain system having at least one differential arrangement (340) for receiving torque from a propulsion unit (330) of said powertrain system and delivering at least a part of said torque to a set of first and second wheels, said method being implemented by a control unit, said method comprising determining a split-friction condition indicative of a wheel slip difference between the first and second wheels, wherein one of the first and second wheels defines a high-friction side of the differential arrangement and the other one of the first and second wheels defines a low-friction side of the differential arrangement; determining a target wheel slip for the high-friction side; and in response to said determined split-friction condition; controlling a brake force on the low-friction side of the differential arrangement based on the target wheel slip on the high-friction side.

摘要： To alleviate the sense of rejection in a brake pedal or a brake lever that arises when a long pressure decreasing mode or a long holding mode has continued in a hydraulic brake device equipped with an actuator that automatically regulates braking liquid pressure in a wheel cylinder of a vehicle without the intervention of an operation by a driver. According to the present invention, there is provided a brake control method for a hydraulic brake device equipped with an actuator that automatically regulates braking liquid pressure in a wheel cylinder of a vehicle without the intervention of an operation by a driver. At a time when the actuator of the hydraulic brake device operates automatically, the method includes: (a) a step of detecting whether pressure to the wheel cylinder is being increased; (b) a step of calculating a time period in which pressure to the wheel cylinder is not being increased; and (c) a step of increasing pressure and decreasing pressure to the wheel cylinder to an extent that has no impact on the braking force of the vehicle after the time period that has been calculated has reached a predetermined time.

摘要： The present invention relates to a method for determining a friction estimate between a road surface and a tire (101a-b) of a vehicle, the tire being arranged on a steerable wheel of the vehicle, and the vehicle an axle rack (104) pivotably attached to a linkage arm (106) connected to the steerable wheel such that a translational motion of the axle rack causes the linkage arm to rotate about a kingpin element (108) such that the linkage arm causes a turning motion of the steerable wheel, the method comprising the steps of: acquiring (S402) a plurality of rack force values; acquiring (S404) a plurality of lateral wheel force values; mapping (S406) a relation between the plurality of rack force values and the lateral wheel force values to a model, and determining (S408) the lateral friction estimate based on the mapping.

摘要： A braking device and a controller are provided. The braking device individually adjusts braking forces that are respectively generated at wheels of a vehicle. The controller executes braking force distribution control for individually controlling the braking forces at the right and left wheels of the vehicle such that slip conditions of the right and left wheels are equal to each other through control of the braking device. The controller executes the braking force distribution control on the basis of an upper limit of a right and left braking force deviation that is a deviation in braking force between the right and left wheels.

摘要： The invention relates to a method for determining an inhomogeneous roadway when a motor vehicle is on a roadway, whose friction coefficient (µ-split) is laterally different, by the active ABS adjustment and a yawing momentum restriction (GMB) of a front wheel (HM wheel) on an increased friction coefficient side. In order to recognise the µ-split in the antilock braking system, which is used by an active steering system, at least the following conditions are to be respected for recognising the roadway: a) the front wheel (LM wheel) is in a pressure reducing phase in the ABS control; a1) the front wheel LM is in the first ABS control cycle; b) the front wheel LM is decelerated at a value greater than a predetermined threshold value; the locking pressure level of the front wheel LM is less than a predetermined threshold value; d) the front wheel (HM wheel) on an increased friction coefficient side is exposed to a filtered deceleration less than a predetermine threshold value and e) the motor vehicle deceleration computed by the ABS is less than a predetermines threshold value.
