The invention discloses a driving torque control method for a vehicle, which can judge whether the vehicle is pre-unstable or not only by comparing operating parameters with pre-instability conditionsof the vehicle no matter what working condition the vehicle is in. When instability of the vehicle occurs in advance, the maximum safe driving torque can be provided for the engine according to the running parameters of the vehicle; compared with the mode that the braking torque of the motor is controlled to be gradually reduced when the vehicle is in a single working condition, the technical scheme is suitable for any working condition, the maximum safe driving torque can be directly provided for the engine, and therefore pre-instability of the vehicle is prevented more rapidly and accurately, and normal running of the vehicle is guaranteed. The use safety of the vehicle is improved; and the accident rate is reduced. In addition, the invention further discloses a driving torque control system for the vehicle and the vehicle.

    本发明公开了一种用于车辆的驱动扭矩控制方法,不论车辆处于何种工况,只需将运行参数和车辆预失稳条件作比较,即可判断车辆是否预发生失稳。在车辆预发生失稳时,能根据车辆的运行参数为发动机提供最大安全驱动扭矩,相比于在车辆处于单种工况下控制电机制动扭矩逐渐降低的方式,本发明的技术方案适用于任何工况,且能直接为发动机提供最大安全驱动扭矩,从而更快速和精准的预防了车辆发生预失稳,保证车辆正常行驶。提高了车辆的使用安全性并降低了事故发生率。此外,本发明还公开了一种用于车辆的驱动扭矩控制系统及汽车。
