The invention discloses a vehicle longitudinal control method, device and equipment, a storage medium and a product, and belongs to the technical field of vehicles. Comprising the steps that in the driving process of the self-driving automobile, the current first speed and first deceleration value of the self-driving automobile are determined based on a reference longitudinal control curve of the self-driving automobile, and the reference longitudinal control curve is used for representing the change condition of displacement of the self-driving automobile along with time; based on the first speed, determining an energy recovery torque matched with the first speed, the energy recovery torque being used for recovering energy generated by deceleration of the autonomous vehicle; based on the first speed, the whole vehicle driving resistance is determined when the driving speed of the self-driving vehicle is the first speed; based on the energy recovery torque, the whole vehicle running resistance and the first deceleration value, the braking torque of the automatic driving vehicle is determined; and longitudinal control is performed on the self-driving automobile through the braking torque.
