What does 4WD TOD mean?

[LeGavin]

TOD is the abbreviation of Torque-On-Demand, which means "Torque-On-Demand four-wheel drive" technology. Introduction to the TOD four-wheel drive system: It can distribute the required power according to the vehicle and road conditions. Under normal circumstances, the TOD system is mainly rear-wheel drive, but when road conditions change, it will transfer torque to the front wheels as needed to provide sufficient traction. How the TOD four-wheel drive system works: TOD uses multiple sensors to detect the working status of each half-shaft, and the parameters detected include vehicle speed, axle speed, throttle opening, brake and ABS system status, etc., to prevent the tires from losing adhesion. The TOD device is installed at the front end of the vehicle's rear drive shaft and is controlled by the electronic control unit (ECU). When the electronic control unit determines that the front wheels are slipping based on the vehicle's driving conditions, it provides an appropriate current to the electromagnetic coil, causing the first-stage clutch to push the cam plate mechanism, which then presses the second-stage wet clutch to engage, thereby distributing the rear axle's torque to the front axle.
