The invention provides torque vectoring with model-predictive torque requests. A vehicle electric torque vectoring system includes a traction motor, a vectoring motor, gears, and a controller. The gears transfer torque from the propulsion and vectoring motors to wheels. The controller, responsive to a step change in an unmodified torque request for the vectoring motor and a predicted torque response of the vectoring motor being greater than the unmodified torque request, commands the vectoring motor to generate torque with a modified torque request less than the unmodified torque request. Thecontroller further, responsive to the predicted torque response becoming less than the unmodified torque request, commands the vectoring motor to generate torque with the unmodified torque request.

    本公开提供“利用模型预测扭矩请求的扭矩矢量控制”。一种车辆电动扭矩矢量控制系统包括牵引马达、矢量控制马达、齿轮和控制器。所述齿轮将扭矩从推进马达和所述矢量控制马达传递到车轮。所述控制器响应于针对所述矢量控制马达的未修改的扭矩请求中的阶跃变化以及所述矢量控制马达的预测的扭矩响应大于所述未修改的扭矩请求,利用小于所述未修改的扭矩请求的修改后的扭矩请求命令所述矢量控制马达生成扭矩。所述控制器进一步响应于所述预测的扭矩响应变得小于所述未修改的扭矩请求,利用所述未修改的扭矩请求命令所述矢量控制马达生成扭矩。
