The invention discloses a torque limiting method and system considering vehicle driving anti-slip performance. Acquiring a driving anti-skid performance torque control boundary under a specific driving working condition; and according to the driving anti-slip performance torque control boundary, a driving torque MAP in a specific driving mode is set, wherein the driving torque MAP is used for representing the corresponding relation between the vehicle speed and the torque value corresponding to the opening degree of an accelerator pedal. According to the method, the driving torque of the vehicle is designed and limited by combining the driving anti-skid performance torque limiting value boundary under the specific driving working condition of the vehicle and the driving anti-skid performance requirement under the specific driving mode, and it is guaranteed that the vehicle cannot transversely move or drift due to sliding of driving wheels when the accelerator opening degree is large under the specific driving styles such as comfort; according to the invention, the difficulty of vehicle control is reduced, and the driving safety and comfort of a driver are improved.
本发明公开了考虑车辆驱动防滑性能的扭矩限制方法和系统。获取特定行驶工况下的驱动防滑性能扭矩控制边界;根据所述驱动防滑性能扭矩控制边界设定特定驾驶模式下驱动扭矩MAP,所述驱动扭矩MAP用于表示车速与油门踏板开度对应的扭矩值的对应关系。本发明通过结合车辆特定行驶工况下的驱动防滑性能扭矩限值边界和特定驾驶模式下的驱动防滑性能要求,对车辆的驱动扭矩进行设计限制,保证舒适等特定驾驶风格下车辆不会在油门开度较大时因驱动轮打滑而发生横移或甩尾;本发明降低了车辆控制的难度,提升了驾驶员的驾驶安全性和舒适性。
