The invention relates to a longitudinal control method for a vehicle, the vehicle and a storage medium, and the method comprises the steps: obtaining a preset target acceleration, and calculating the actual acceleration of the vehicle; calculating a distributed acceleration based on the target acceleration and the actual acceleration of the vehicle; the maximum negative torque parameter of a whole vehicle driving mechanism of the vehicle is obtained; calculating a torque request value of a whole vehicle driving mechanism of the vehicle and a brake pressure request value of a main cylinder brake mechanism of the vehicle based on a comparison result of the maximum negative torque parameter and the distributed acceleration; and based on the torque request value and the braking pressure request value, a whole vehicle driving mechanism and a main cylinder braking mechanism are combined to conduct braking operation on the vehicle. By means of the vehicle longitudinal control method, the problem that an ACC software architecture cannot adapt to and adopt EBS and other novel braking system architectures is solved, and the vehicle longitudinal control method capable of coordinately controlling the torque output of the vehicle control unit and the braking force output of the novel braking system is achieved.
