The invention discloses a ramp estimation method and system, electronic equipment and a readable storage medium. The method comprises the steps that data collected by an accelerometer, data collected by a gyroscope and data collected by a speed sensor are obtained; calculating a first acceleration of the vehicle according to the data collected by the speed sensor; determining a first gradient value according to the first acceleration and data acquired by the accelerometer; determining the driving state of the vehicle according to a plurality of vehicle states, wherein each vehicle state comprises a static state and a non-static state; and determining a target filtering coefficient according to the driving state of the vehicle. The first gradient value is filtered according to the target filter coefficient to obtain a second gradient value, the filter coefficient corresponding to the first state is set to be smaller than the filter coefficient corresponding to the second state, so that the obtained second gradient value is relatively smooth, a smoother target gradient value is obtained in combination with data collected by a gyroscope, and the riding experience feeling of a user is improved.

    本申请公开了一种坡道估计方法、系统、电子设备及可读存储介质,所述方法包括:获取加速度计所采集的数据、陀螺仪所采集的数据以及速度传感器所采集的数据;根据所述速度传感器所采集的数据,计算车辆的第一加速度;根据所述第一加速度以及所述加速度计采集的数据,确定第一坡度值;根据多个车辆状态确定所述车辆的行车状态,每个所述车辆状态包括静止状态与非静止状态;根据所述车辆的所述行车状态确定目标滤波系数。根据所述目标滤波系数对第一坡度值进行滤波得到第二坡度值,设置第一状态对应的滤波系数小于第二状态对应的滤波系数,使得到的第二坡度值较为光滑,结合陀螺仪采集的数据得到更平滑的目标坡度值,提高了用户的乘车体验感。
