Differential Electronic Module (Dem) - Specifications, Other: Specifications Volvo XC70 II

CALCULATED FRONT WHEEL DRIVE TORQUE

The value indicates one engine control module (ECM) calculated torque, supplied to the Active on Demand Coupling input shaft (propeller shaft). Calculation includes the gear ratio of the transmission and the final drive. The differential electronic module (DEM) obtains the value via the controller area network (CAN) from the engine control module (ECM).

Measurement range: -16.376 Nm to +16.384 Nm.

REAR AXLE TORQUE

The value indicates the torque transferred to the rear axle, calculated by the AOC unit (coupling).

Measurement range: 0 - 8191 Nm.

REQUESTED REAR AXLE TORQUE

The value indicates one brake control module (BCM) requested maximum rear axle torque. The differential electronic module (DEM) uses this information to correctly transfer torque to the rear axle. Also, see the "Rear axle torque" parameter.

Measurement range: 0 - 8191 Nm.

REQUESTED FRONT WHEEL DRIVE TORQUE

The value indicates the requested engine torque of the driver. The differential electronic module (DEM) uses this information to correctly transfer torque to the rear axle.

Measurement range: -16.376 Nm to +16.375 Nm.

The value indicates one engine control module (ECM) calculated torque, supplied to the Active on Demand Coupling input shaft (propeller shaft). Calculation includes the gear ratio of the transmission and the final drive. The differential electronic module (DEM) obtains the value via the controller area network (CAN) from the engine control module (ECM).

Measurement range: -16.376 Nm to +16.384 Nm.
