The invention discloses a gradient estimation method, a storage medium and electronic equipment. The gradient estimation method comprises the steps that the driving acceleration As of a vehicle in thedriving direction is acquired; the actual acceleration Ax of vehicle driving is obtained; a current gradient value alpha is calculated according to the driving acceleration and the actual acceleration; a wheel speed amplification M is obtained; when the wheel speed amplification M is smaller than or equal to a preset wheel speed amplification Q, a current slope value alpha is output; and when thewheel speed amplification M is greater than the preset wheel speed amplification Q, a gradient value calculated before entering the bumpy road is outputted. The phenomenon that when the vehicle runson bumpy roads and other bad roads, longitudinal control of the vehicle is influenced due to abnormal gradient calculation caused by fluctuation of the measurement value of the longitudinal acceleration sensor can be avoided, and normal running of the vehicle is guaranteed.

    本申请公开了一种坡度估算方法、存储介质和电子设备,其包括:获取车辆行驶方向的行驶加速度As;获取车辆行驶的实际加速度Ax;根据行驶加速度和实际加速度计算当前坡度值α;获取轮速增幅M;当所述轮速增幅M小于等于预定轮速增幅Q时,输出当前坡度值α;当所述轮速增幅M大于预定轮速增幅Q时,输出进入颠簸路之前计算的坡度值。利用本申请能够避免车辆行驶在颠簸路等坏路上时由于纵向加速度传感器测量值的波动导致坡度计算异常影响车辆的纵向控制,保证车辆的正常行使。
