The invention discloses a whole vehicle braking energy recovery method, device and equipment and a storage medium, and relates to the technical field of whole vehicle braking energy recovery, and the whole vehicle braking energy recovery method comprises the steps that multiple sets of motor rotating speeds of a test vehicle and recovery torque corresponding to each set of motor rotating speed are obtained; displaying a plurality of groups of motor rotating speeds and recovery torques in a parameterized curve form, and obtaining a plurality of basic control points taking the motor rotating speeds and the recovery torques as plane coordinates; taking the recovery torque of the basic control point as a control handle, taking the minimum set kilometer power consumption value as a target function, and obtaining optimized basic control point coordinates through an iterative algorithm; and the parameterized curve is adjusted based on the optimized basic control point coordinates, and an optimized braking energy recovery curve is obtained for whole vehicle braking energy recovery. According to the method, a real vehicle does not need to be calibrated for multiple times, curve optimization can be completed only by adjusting the coordinates of the control points, and the method is low in energy consumption, high in recovery efficiency, high in operability, convenient and practical.
