Downloaded from www.Manualslib.com manuals search engine The Tiggo 4WD is the first 4WD vehicle produced by Chery. The 4WD system is equipped with a QR523T transaxle
manufactured by Chery.
An active torque transfer system is used, and an interactive torque management system (ITM) is equipped to make
it possible to intelligently distribute the drive force for the front wheels and rear wheels according to different road
conditions. For example, on a smooth road, the vehicle utilizes front-wheel drive. When road conditions worsen, the
ITM will automatically switch to 4WD. The use of ITM allows the Tiggo vehicle to be more economical and more
efficient than the common 4WD system.
Operation
The intelligent 4WD system is controlled by an interactive torque management system (ITM) module. The ITM mod-
ule communicates with the Engine Control Module (ECM) and the Antilock Brake System (ABS) controller through the
CAN network. The ITM module collects data from sensors on the vehicle body to determine the condition of the drive
wheels. Based on the sensor inputs, the ITM module controls the ITM controller. The ITM controller will then distrib-
ute a portion of the torque to the rear drive axle as needed. The ITM controller works as an electromagnetic clutch.
Different torque can be transferred by changing the electric current of the ITM controller. The ITM controller will be
able to distribute the torque of the front drive axle and the rear drive axle at different ratios according to the various
dynamic conditions of the vehicle.
