System for Controlling Torque Distribution

Abstract

A torque distribution control system comprises a torsion unit for detecting traction on wheels of a primary driving axle that is continuously engaged with a drive source or a source of torque power. The amount of traction detected is converted to a signal with variable signal strength, the signal strength correlating to the amount of traction detected by the torsion unit. The signal strength capable of being adjusted automatically based on select parameters and / or manually based on a driver's input. And, in response to the signal, actuators engage and control operations of the vehicle such as the drive source, a braking system, and / or an axle clutch, with the level of engagement dependent upon the signal strength.

AI Technical Summary

Benefits of technology

[0009]Accordingly, it is an object of the invention to directly detect changes in the traction between the wheels of the continuously engaged primary driving axle and the road, thereby ensuring an accurate quantitative assessment of traction.

[0010]It is another object of the invention to minimize the delay between detection of traction loss and the execution of corrective measures to correct the traction loss.

[0012]It is a further object of the invention to provide a system for controlling torque distribution that improves cruising stability of a vehicle.

Problems solved by technology

The speed and acceleration sensors do not directly detect loss of traction.

Therefore, calculation and determination of traction loss is done after loss of traction has already occurred, thereby adversely affecting cruising stability of the vehicle.

A disadvantage of these prior art torque distributors is the delay caused by the reliance on the indirect determination of traction loss.

However, the detection of such discrepancies by the ABS sensors represents a delayed detection of traction loss.

Another disadvantage of electronically controlled torque distribution systems is the complete absence of quantitative data regarding the magnitude of the lost traction.
