The invention discloses a turning control method and device for a four-wheel-drive vehicle. Obtaining a target turning control mode selected by the user based on the driving scene; current steering information and current driving torque output through an accelerator pedal are obtained; if the non-pavement control mode is selected, the current driving torque is distributed to two front wheels for driving control, locking control is conducted on inner rear wheels based on the current steering information, and sliding control is conducted on outer rear wheels based on the current steering information; if the pavement control mode is selected, the current driving torque is distributed to the two rear wheels for driving control, and drifting control is conducted on the two rear wheels based on the current steering information; and if the in-situ turning control mode is selected, distributing the current driving torque to four wheels for driving control based on the current steering information. The problem of reducing the turning radius under different working conditions is solved, the complexity of steering operation is reduced, the steering time is shortened, and the driving control experience of the vehicle and the use convenience of the vehicle are improved.

    本发明公开了一种四驱车辆的转弯控制方法及装置。获取用户基于驾驶场景所选择的目标转弯控制模式;获取当前转向信息和通过加速踏板输出的当前驱动扭矩;若选择非铺装路面控制模式,则将当前驱动扭矩分配至两个前轮进行驱动控制,并基于当前转向信息对内后轮进行抱死控制并对外后轮进行滑转控制;若选择铺装路面控制模式,则将当前驱动扭矩分配至两个后轮进行驱动控制,并基于当前转向信息对两个后轮进行甩尾控制;若选择原地掉头控制模式,则基于当前转向信息,将当前驱动扭矩分配至四个车轮进行驱动控制。本发明解决了不同工况下缩小转弯半径的问题,降低转向操作的复杂性和转向所用时间,提高了车辆的驾控体验和车辆的使用便利性。
