    Abstract: A braking control device includes a braking control unit that controls a braking device, a load reduction amount derivation unit that derives a reduction amount of a load input from a vehicle body to a suspension for a second wheel, and an anti-force derivation unit that derives an anti-lift force. The braking control unit performs posture braking processing of adjusting the second braking force so that the difference between the reduction amount of the load and the anti-lift force is less than or equal to a difference determination value, and adjusting the first braking force so that the vehicle braking force becomes the required value.

    Abstract: This braking control device comprises a first unit for outputting a supply pressure in accordance with operation displacement of a braking operation member, a second unit between the first unit and a wheel cylinder to increase the supply pressure and output a wheel pressure to the wheel cylinder, a displacement sensor for detecting the operation displacement, and a supply pressure sensor for detecting the supply pressure. The first unit selects either a first mode in which the operation displacement and the supply pressure are independent or a second mode in which the operation displacement and the supply pressure are linked. When the displacement sensor is normal, the first unit selects the first mode and increases the supply pressure based on the operation displacement. When the displacement sensor is not normal, the first unit selects the second mode, and the second unit increases the wheel pressure based on the supply pressure.

    Abstract: A decision and control method for ADAS in a preceding vehicle obstruction scene based on V2X, ADAS system and intelligent networked vehicle, the decision and control method comprises: based on V2X perspective perception technology, collaboratively perceiving driving status information of an obstructed preceding vehicle, and fusing with driving status information of a potentially conflicting vehicle perceived by on-board perception of ego vehicle; based on the fused information, performing behavior judgment of the potentially conflicting vehicle; making a control decision of the ego vehicle according to judgment result. Through the application of V2X technology, the fusion of on-board perception technology and roadside perception technology is achieved, more accurate, more reliable and all-weather environmental perception information is obtained, and perception obstacles in key dangerous scenes are solved. In particular, in the scene where the line of sight to the preceding vehicle is obstructed, it realizes functions that traditional ADAS (based on on-board perception) cannot achieve or enhances the performance and reliability of traditional ADAS functions.

    Abstract: A control unit for controlling a heavy-duty vehicle is arranged to obtain an initial inverse tire model configured to represent a preliminary relationship between wheel slip and generated longitudinal wheel force for at least one wheel of the heavy-duty vehicle. The control unit obtains data from a tire thread deflection sensor configured to measure an amount of tire thread deflection associated with the at least one wheel, and an amount of wheel slip of the at least one wheel corresponding to the amount of tire thread deflection. The control unit updates the obtained initial inverse tire model based on the amount of tire thread deflection and on the corresponding amount of wheel slip. The control unit controls the heavy-duty vehicle by configuring a target wheel speed or a target wheel slip of the at least one wheel based on the updated inverse tire model to generate a target longitudinal wheel force.
