The invention discloses a gradient determination method and device, a vehicle and a storage medium. The gradient determination method comprises the following steps: determining a candidate gradient value to be filtered; according to the measured angular velocity of the vehicle measured in a set time period, the angle variation corresponding to the measured angular velocity is determined; a target complementary filter coefficient is determined according to an initial complementary filter coefficient and the vehicle acceleration of the vehicle, and the initial complementary filter coefficient is determined according to an application scene; complementary filtering is carried out according to the candidate slope value, the angle variation, the target complementary filtering coefficient and a previous slope value, a current slope value is determined, and the previous slope value is a slope value determined before the current slope value. According to the technical scheme, complementary filtering is performed according to the candidate gradient value, the angle variation, the target complementary filtering coefficient and the previous gradient value to determine the current gradient value, and the gradient determination accuracy is improved.
