The invention relates to a vehicle pose calculation method, a vehicle, computer equipment and a storage medium. The method comprises the following steps: acquiring the current speed of a vehicle and the current course angular velocity value of the vehicle; when the current vehicle speed is zero and the current course angular velocity value is larger than a preset course angular velocity threshold value, the course angle of the vehicle is calculated according to the current course angular velocity value; when the current vehicle speed is zero and the current course angular velocity value is smaller than a preset course angular velocity threshold value, taking a zero value as the value of the course angle; calculating a pose change track of the vehicle in unit time through a wheel pulse counting algorithm; integral transformation operation based on Lie group closed integral is carried out according to the calculated course angle and the pose change track, a pose transformation matrix of the vehicle is obtained, and the pose of the vehicle is determined according to the pose transformation matrix. By adopting the method, the accuracy of vehicle pose determination can be improved.
