The invention relates to a wheel slip enhancement function for heavy vehicles. A computer-implemented method for controlling at least one driven and/or braked wheel (102) of a heavy vehicle (100), the method comprising: obtaining a motion request (areq, Fx) indicative of a desired longitudinal acceleration and/or longitudinal force associated with the vehicle (100); and configuring a wheel slip limit value ([lambda] lim) as a nominal value, the wheel slip limit value ([lambda] lim) being indicative of a maximum allowable wheel slip of the at least one driven and/or braked wheel (102); and in response to detecting the enhancement signal (361), increasing the wheel slip limit value ([lambda] lim) from a nominal value to an enhanced wheel slip value, and controlling the at least one driven and/or braked wheel (102) in accordance with the motion request (areq, Fx) and limited by the wheel slip limit value ([lambda] lim).
本公开涉及用于重型车辆的车轮滑移增强功能。一种用于控制重型车辆(100)的至少一个从动和/或制动车轮(102)的计算机实现方法,该方法包括:获得指示与车辆(100)相关联的期望纵向加速度和/或纵向力的运动请求(areq,Fx);以及将车轮滑移限制值(λlim)配置为标称值,该车轮滑移限制值(λlim)指示所述至少一个从动和/或制动车轮(102)的最大允许车轮滑移;以及响应于检测到增强信号(361)而将车轮滑移限制值(λlim)从标称值增加到增强车轮滑移值,以及根据运动请求(areq,Fx)并受限于车轮滑移限制值(λlim),控制所述至少一个从动和/或制动车轮(102)。
