The invention discloses a vehicle instability judgment method and device, a storage medium, a controller and a vehicle, and the method comprises the steps that state parameters of the vehicle at the current moment are obtained, and the state parameters comprise the yaw velocity and the side slip angle of the vehicle; according to the state parameters at the current moment, the yaw velocity and the side slip angle of the vehicle at the future target moment are predicted, and a predicted value of the yaw velocity and a predicted value of the side slip angle are obtained; and according to the yaw velocity predicted value and the side slip angle predicted value, whether the vehicle has an instability trend or not is judged. According to the method, the yaw velocity and the side slip angle of the vehicle at the future target moment are predicted based on the state parameters of the vehicle at the current moment, the stability of the vehicle at the future target moment is predicted before the vehicle is unstable at the current moment, and the stability of the vehicle is pre-judged in an advanced pre-judgment mode. Therefore, vehicle stability control is involved when it is judged that the vehicle tends to be unstable, and the vehicle stability is improved.
本发明公开了一种车辆失稳判定方法、装置及存储介质、控制器、车辆,方法包括:获取车辆当前时刻的状态参数,其中,状态参数包括车辆的横摆角速度和质心侧偏角;根据当前时刻的状态参数预测车辆未来目标时刻的横摆角速度和质心侧偏角,得到横摆角速度预测值和质心侧偏角预测值;根据横摆角速度预测值和质心侧偏角预测值,判定车辆是否存在失稳趋势。该方法基于车辆当前时刻的状态参数,对车辆未来目标时刻的横摆角速度和质心侧偏角进行预测,在车辆当前时刻未发生失稳前对车辆未来目标时刻的稳定性进行预测,采用超前预判的方式对车辆稳定性预判,从而在判断车辆趋向失稳时介入车辆稳定性控制,提高车辆稳定性。
