In some embodiments of the present invention, the constant vehicle speed may include a plurality of sub-constant vehicle speeds of different vehicle speeds, it should be explained that the constant vehicle speed may include two sub-constant vehicle speeds of different vehicle speeds, and the constant vehicle speed may also include more than two sub-constant vehicle speeds of different vehicle speeds, after the control module controls the N-gear of the vehicle to be powered down, the detection module may detect a whole vehicle resistance value of the vehicle running at the plurality of sub-constant vehicle speeds of different vehicle speeds, after the control module controls the vehicle to be powered up, the detection module may detect a whole vehicle driving power value of the vehicle running at the plurality of sub-constant vehicle speeds of different vehicle speeds, thereby detecting a whole vehicle resistance value of the vehicle at the plurality of different vehicle speeds and a whole vehicle driving at the plurality of different vehicle speeds in one detection, thereby improving detection accuracy of the detection module, and further improving accuracy of detecting influences of different oil products of the speed reducer on vehicle energy consumption, the test efficiency can be improved, and the test period is shortened.

In some embodiments of the present invention, the vehicle is statically placed until the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value meet the preset condition, the vehicle is controlled to be powered on, and the detecting the whole vehicle driving power value at the constant vehicle speed may include: before the vehicle is controlled to be powered on, the wheel loading resistance value is set, and it should be noted that before the control module controls the vehicle to be powered on, the wheel loading resistance value can be set on the detection module, and the wheel loading resistance value can be set by a formula of Y ═ a + bx + cx²The specific numerical value of the wheel loading resistance value is determined, wherein Y is the wheel loading resistance value, x is the vehicle speed, a, b and c are constants, the numerical values of a, b and c can be adjusted according to actual requirements, and the numerical values of a, b and c can also be adjusted according to the electric core temperature value and/or the battery electric quantity value and/or the reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value, so that the whole vehicle driving power value of the vehicle can be accurately detected, and the detection error can be avoided.

In some embodiments of the invention, the vehicle is placed to be static until the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value meet the preset conditions, the vehicle is controlled to be powered on, after the vehicle driving power value at constant vehicle speed is detected, whether the vehicle resistance value and the vehicle driving power value meet the increase along with the increase of the vehicle speed is judged, if yes, the speed reducer oil product is replaced, and if not, the speed reducer oil product is reused for repeated tests. It should be explained that, after the detection module detects the whole vehicle driving power value when the vehicle is at a constant speed, the inspector can judge whether the whole vehicle resistance value and the whole vehicle driving power value are increased along with the increase of the vehicle speed, if the whole vehicle resistance value and the whole vehicle driving power value are increased along with the increase of the vehicle speed, the detection data is correct, the oil product of the speed reducer can be replaced, the whole vehicle resistance value and the whole vehicle driving power value of the vehicle when different oil products of the speed reducer are used are detected, if the whole vehicle resistance value and the whole vehicle driving power value are not increased along with the increase of the vehicle speed, the detection data has errors, the oil product of the speed reducer needs to be reused for repeated tests, therefore, the influence on test detection results caused by the errors of the detection data can be avoided.

In some embodiments of the present invention, if it is determined that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value do not satisfy the preset condition, the vehicle stands still, obtains initial state information of the vehicle, and determines whether the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value satisfy the preset condition. It should be noted that, if the determining module determines that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value do not satisfy the preset condition, the vehicle is stationary, when the vehicle is stationary, the obtaining module may obtain initial state information of the vehicle, the obtaining module may transmit the obtained initial state information of the vehicle to the determining module, the determining module may determine whether the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value satisfy the preset condition according to the initial state information of the vehicle transmitted by the obtaining module, specifically, if the determining module determines that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value satisfy the preset condition, the control module controls the vehicle to be powered on or powered off, if the judgment module judges that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value do not meet the preset conditions, the vehicle is continuously placed until the judgment module judges that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value meet the preset conditions, therefore, the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value meet the preset conditions in the detection process, and the situation that the detected tire pressure value meets the preset conditions due to the fact that the electric core temperature value and/or the battery electric quantity value and/or the speed reducer oil temperature value and/or the current test environment temperature value and/or the tire pressure value do not meet the preset conditions can be avoided The measurement results have errors.
