The invention provides a braking energy recovery adjustment control method. A whole vehicle controller collects a slope signal of a current road through a slope sensor, when the slope shows downhill and the duration time for which the slope is larger than the first set value is larger than the second set value, it is judged that a vehicle is in the long-distance downhill work condition, braking energy recovery adjustment control is started, and the whole vehicle controller decides whether an instruction for increasing the braking torque is sent to a motor controller or not through the comparison between the current vehicle speed and the target vehicle speed. The recycling rate is obviously increased especially under the rough mountain long-distance downhill driving working condition, and energy losses produced by vehicle potential energy descending are effectively recycled.
