The invention relates to a control device for operating a road-coupled all-wheel drive vehicle, comprising at least one electronic control unit, the all-wheel drive vehicle comprising at least one first electric drive motor associated with a primary shaft as a primary motor and at least one second electric drive motor associated with a secondary shaft as a secondary motor. According to the invention, the control unit has a torque limiting module in such a way that, when a desired change in the all-wheel drive coefficient is detected on the basis of a defined signal that is ahead of the filtered driver-desired signal, the desired change in the all-wheel drive coefficient is detected before the individual target torque itself is adjusted. A torque limit value of a single target torque of the electric drive motor is preset in a step-wise manner as a function of a predetermined varying all-wheel drive factor.

    本发明涉及一种用于运行道路耦联式全轮驱动车辆的控制装置,所述控制装置包括至少一个电子控制单元,该全轮驱动车辆包括至少一个分配给主轴的第一电驱动马达作为主马达和至少一个分配给副轴的第二电驱动马达作为副马达。根据本发明,所述控制单元如此具有扭矩限制模块,使得在基于定义的超前于经过滤的驾驶员期望信号的信号识别全轮驱动系数的要预期的变化时,在调节单目标力矩本身之前,根据预定的变化的全轮驱动系数阶跃式地预设电驱动马达的单目标力矩的扭矩限值。
