HEAVY TRUCK TORQUE SENSING

DIFFERENTIAL TORQUE SENSING

Methode’s magnetoelastic torque sensors are extremely robust with no need for recalibration over time. They can be easily integrated into the differential for measuring at the input or outputs. Measuring the torque at the differential allows for an accurate closed loop control of the engine and transmission thus improving driving dynamics, reducing emissions and allowing for real time condition monitoring and predictive maintenance. In addition to this the torque information can be used to derive vehicle weight and therefore used for onboard weighing applications which will become increasingly critical when future legislation comes into effect.

EPS TORQUE SENSING

Methode has overcome many of the challenges imposed by traditional steering sensors which implement a torsion bar setup. These sensors derive torque through a differential angle measurement through flex or deflection in the steering column. Methode’s magnetoelastic sensor technology allow for a real torque measurement directly on the steering shaft.

The advantages of Methode’s steering torque sensors include:

• A real and direct torque measurement, not estimated.
• an accurate nominal torque measurement while maintaining the required mechanical overload protection.
• high signal to noise performance.
• No flex in the system leading to a more precise and direct steering feel.
• Less mechanical complexity and a reduced packaging space.
• No lifetime or ageing affects, no need for recalibration.
• ASIL system level performance possible.
