The invention provides an anti-rollover method and device for a vehicle, a terminal and a storage medium. The method comprises the steps of judging whether a vehicle has a rollover trend or not based on the transverse load transfer rate of the vehicle; if the vehicle has the rollover tendency, calculating an additional yawing moment for inhibiting the rollover of the vehicle based on the transverse load transfer rate and a radial basis function neural network PID controller; and determining a target wheel based on the lateral load transfer rate, and calculating a target braking torque based on the additional yaw torque to brake the target wheel based on the target braking torque. Whether the vehicle has the rollover trend or not is judged according to the transverse load transfer rate, the additional yawing moment for rollover suppression of the vehicle is calculated through the radial basis function neural network PID controller when the vehicle has the rollover trend, the calculation speed of the additional yawing moment can be increased, the target wheel is braked in time before rollover, and the vehicle rollover suppression efficiency is improved. Therefore, the anti-rollover response speed and the anti-rollover effect of the vehicle are improved.

本发明提供一种车辆的防侧翻方法、装置、终端及存储介质。该方法包括：基于车辆的横向载荷转移率判断车辆是否具有侧翻趋势；若车辆具有侧翻趋势，则基于横向载荷转移率和径向基神经网络PID控制器计算用于抑制车辆侧翻的附加横摆力矩；基于横向载荷转移率确定目标车轮，并基于附加横摆力矩计算目标制动力矩，以基于目标制动力矩对目标车轮进行制动。本发明通过横向载荷转移率判断车辆是否有侧翻趋势，在车辆有侧翻趋势时通过径向基神经网络PID控制器计算对车辆进行侧翻抑制的附加横摆力矩，可以提高附加横摆力矩的计算速度，并在发生侧翻前及时对目标车轮进行制动，从而提高车辆抗侧翻的响应速度和抗侧翻效果。
