Thanks to Magnetic Torque Overlay (MTO), drivers of heavy duty trucks can benefit from enhanced safety, comfort and ADAS features previously found only in lighter vehicles, such as:
Electric Power Steering (EPS) systems are required for ADAS features while at the same time are unable to simply steer heavy duty trucks because of the heavy load outputs.
This conundrum created a void in the marketplace and confused end-customers on why some ADAS features are available on smaller, less expensive half ton trucks (using EPS systems) and not on larger, more expensive heavy duty trucks (requiring HPS systems).
MTO consists of an HPS gear equipped with an integrated electromagnetic actuator with additional pressure sensing hardware, an electric control module and additional software – thus enabling ADAS features as well as a highly tunable, premium steering feel.
MTO is accomplished with no additional sliding or contacting components, belts, gears, or motors, which can compromise steering feel and performance by adding friction or inertia.
All MTO-enabled functionality can be applied to both recirculating ball as well as rack & pinion gears. The system also complies with ASIL D safety critical standards.
