The invention discloses a braking energy recovery method and device, a vehicle and a storage medium, and belongs to the technical field of vehicles. The method comprises the steps that a braking instruction triggered by a target user is responded, a target braking requirement is determined based on current braking time, current vehicle speed, current braking parameters and a target mapping relation, and the target mapping relation is used for indicating the relation between the braking time, the vehicle speed, the braking parameters and the braking requirement in the vehicle driving process; the brake parameters comprise brake pedal pressure and/or brake pedal travel; determining a braking demand torque based on the target braking demand, a current vehicle driving state and vehicle physical parameters; and a first target braking torque is determined based on the braking demand torque, and vehicle braking and braking energy recovery are carried out based on the first target braking torque. According to the method, the driving experience of the user is fully considered during vehicle braking and braking energy recovery, so that the driving smoothness in the braking process is improved.
