Problems solved by technology

[0006] Under the conditions of the existing technology, although the torque manager can be inspected, it is only a random inspection, and a bench is required, and it is only the inspection of the combination of three types of friction plates, high, middle, and low, so the inspection is neither convenient nor comprehensive.

Embodiment Construction

[0038] The core of the present invention is to provide a detection method and system of a torque manager. The method and system can carry out the off-line detection work of the torque manager on the whole vehicle after the production of the main engine factory is completed, no bench is required, and the operation is simple. And can cover all torque output ranges.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of t...

Abstract

The invention discloses a torque manager detection method and system. The method comprises the steps that a gearbox gear control signal and an accelerator pedal control signal are controlled and maintained to be constant; oil pump pressure is controlled through a torque manager according to the preset rules so that a four-wheel-drive drum is enabled to output target torque; whether the target torque is in the preset range is judged, wherein the preset range is the range of theoretical torque outputted by the four-wheel-drive drum when the gearbox gear control signal and the accelerator pedal control signal are maintained to be constant and the torque manager controls the oil pump pressure according to the preset rules; and the torque manager is qualified if the judgment result is yes. According to the method and the system, offline detection work of the torque manager can be performed on the complete vehicle after completion of production in the main engine plant with no requirement for the rack so that operation is easy and can cover all the torque output range.

Description

technical field [0001] The invention relates to the technical field of transmission detection, in particular to a detection method and system for a torque manager. Background technique [0002] Compared with the era of vehicles that used relatively simple and mechanical devices to meet basic driving needs, it has gradually developed into the era of vehicles with intelligent four-wheel drive systems. [0003] The intelligent four-wheel drive system includes: power take-off, torque manager (inter-axle torque distribution control unit), rear final drive. The intelligent four-wheel drive system adopts mature control technology to continuously monitor the vehicle status, pump oil through the oil pump, adjust the pressing force between the friction plates, and intelligently distribute the torque of the front and rear axles to obtain the best vehicle stability and handling. performance and fuel economy. [0004] After the whole vehicle is assembled, in order to ensure that the ke...
