The invention provides a vehicle curve torque control method and device. The method comprises the steps of obtaining vehicle driving data of a target vehicle; judging whether a curve torque adjustment condition is met or not currently based on the vehicle driving data; if yes, whether the curve torque distribution and adjustment function needs to be activated or not is judged according to the vehicle driving data; if yes, a curve torque distribution adjusting function is activated; determining a curve torque distribution proportion according to the vehicle driving data; and correspondingly controlling the front and rear axle torques of the target vehicle according to the curve torque distribution proportion. Therefore, according to the method and the device, the curve torque distribution coefficient can be adjusted through reasonable distribution of the torque of the front shaft and the rear shaft according to different curve road conditions and driving states, the flexibility is good, and the curve driving safety and the control stability of the vehicle can be improved.

    本申请提供一种车辆弯道扭矩控制方法及装置,该方法包括:获取目标车辆的车辆行驶数据;基于车辆行驶数据判断当前是否达到弯道扭矩调整的条件;如果是,则根据车辆行驶数据判断是否需要激活弯道扭矩分配调整功能;如果是,则激活弯道扭矩分配调整功能;根据车辆行驶数据确定弯道扭矩分配比例;根据弯道扭矩分配比例对目标车辆的前后轴扭矩进行相应的控制。可见,该方法及装置能够根据不同的弯道路况和行驶状态通过前后轴扭矩合理分配来调节弯道扭矩分配系数,灵活性好,有利于提高车辆弯道行驶的安全性和操控稳定性。
