Summary:To provide improved vehicle control units, methods and functions which meet safety requirements imposed on heavy duty vehicles.SOLUTION: An MSD control unit 230 for a heavy duty vehicle is configured to control one or more MSDs 220, 250 coupled with a wheel 210, and is disposed to be communicatively coupled 235 for receiving control commands from a vehicle motion management VMM unit 260 comprising wheel-speed request and/or wheel-slip request to control vehicle motion by the MSDs 220, 250. The MSD control unit 230 is configured to obtain a capability range indicating a behavior range of the wheel 210. The VMM unit 260 can influence the behavior of the wheel for the capability range. The MSD control unit 230 is arranged to monitor the wheel behavior and to detect if the wheel behavior is outside of the capability range, and is arranged to trigger a control intervention function if the monitored wheel behavior is outside of the capability range.SELECTED DRAWING: Figure 2 【課題】大型車両に課せられた安全要求事項に合致する、改善された車両制御ユニット、方法および機能を提供する。【解決手段】大型車両のためのＭＳＤ制御ユニット２３０は、車輪２１０と結合された１つまたは複数のＭＳＤ２２０、２５０を制御するように構成され、ＭＳＤ２２０、２５０によって車両運動を制御するための車輪速度要求および／または車輪スリップ要求を含む制御コマンドを車両運動管理ＶＭＭユニット２６０から受け取るために、通信結合される２３５ように配置され、ＭＳＤ制御ユニット２３０は、車輪２１０の挙動範囲を示す能力範囲を得るようになされ、ＶＭＭユニット２６０は、上記能力範囲に対して車輪の挙動に影響を及ぼすことができ、ＭＳＤ制御ユニット２３０は、車輪挙動を監視し、かつ車輪挙動が能力範囲外であるかどうかを検出するようになされ、監視された車輪挙動が能力範囲外である場合、制御介入機能をトリガするようになされる。【選択図】図２
