The present disclosure provides a "powertrain torque control system". A vehicle has an electric machine, a first axle shaft, a second axle shaft, a steering wheel, and a controller. The first axle shaft and the second axle shaft are configured to deliver torque from the electric machine to a first wheel and a second wheel, respectively. The controller is programmed to respond to (i) locking the first axle shaft to the second axle shaft, (ii) displacement of at least one of the first axle shaft and the second axle shaft or the steering wheel, and (iii) Commanding a torque of the electric machine to an expected value results in a torque distribution to the first and second axle shafts exceeding a torque capacity of at least one of the first and second axle shafts, the torque of the electric machine being truncated to less than the expected value.

    本公开提供了“动力传动系统转矩控制系统”。一种车辆,其具有电机、第一半轴、第二半轴、方向盘和控制器。所述第一半轴和所述第二半轴被配置为将转矩从所述电机分别递送到第一车轮和第二车轮。所述控制器被编程为:响应于(i)将所述第一半轴锁定到所述第二半轴、(ii)所述第一半轴和所述第二半轴或所述方向盘中的至少一者的移位以及(iii)将所述电机的转矩命令为期望值导致对所述第一半轴和所述第二半轴的转矩分配超过所述第一半轴和所述第二半轴中的至少一者的转矩容量,将所述电机的所述转矩截断为小于所述期望值。
