The invention relates to the technical field of automobile control, and discloses an anti-skid control method, device and equipment and a storage medium. When the road surface risk judgment coefficient is greater than or equal to a slip coefficient threshold value and/or the change rate of the acceleration is greater than or equal to a first acceleration change threshold value, determining that the vehicle has a potential slip trend; when the vehicle has a potential slip trend, a torque adjustment slope is obtained according to the road surface risk judgment coefficient or the change rate of the acceleration; and determining an execution torque according to the torque adjustment slope, and sending the execution torque to a motor controller. According to the method, the potential slip trend is judged through the road surface risk judgment coefficient or the change rate of the acceleration, early-stage intervention control is carried out when the potential slip trend exists, torque can be effectively reduced before ASR/TCS intervention, and the driving smoothness and safe control are improved.

    本发明涉及汽车控制技术领域,其公开了防滑控制方法、装置、设备及存储介质,通过获取路面风险判断系数以及加速度的变化率;在所述路面风险判断系数大于等于打滑系数阈值,和/或所述加速度的变化率大于等于第一加速度变化阈值时,确定车辆存在潜在打滑趋势;在所述车辆存在潜在打滑趋势时,根据所述路面风险判断系数或所述加速度的变化率得到扭矩调整斜率;根据所述扭矩调整斜率确定执行扭矩,将所述执行扭矩发送至电机控制器。通过路面风险判断系数或加速度的变化率进行潜在打滑趋势的判定,在存在潜在打滑趋势时,进行前期干预控制,能在ASR/TCS介入前有效降扭,提高驾驶的平顺性与安全操控。
