The invention provides a vehicle braking energy recovery method and system and a vehicle. The method comprises the steps that a planning control system obtains vehicle environment information and vehicle running state information; analyzing and processing the vehicle environment information and the vehicle running state information to obtain expected deceleration; the expected deceleration is analyzed and processed, and the braking distance of the vehicle is obtained; determining a bridge control instruction and a negative torque instruction based on the braking distance; and sending the bridge control instruction and the negative torque instruction to a power control system. The power control system receives a bridge control instruction and a negative torque instruction obtained by the planning control system; sending the bridge control instruction to a target bridge for bridge control; and the negative torque instruction is sent to a corresponding motor, the motor conducts vehicle braking control according to the negative torque instruction, and the motor converts vehicle kinetic energy into electric energy to be stored in a storage battery through a generator working mode so that braking energy can be recycled.
