Steer-by-Wire Systems with Integrated Torque Feedback Improve Steering Performance and Reduce Cost
- Created: Wednesday, 01 June 2011
The integrated steer-by-wire unit incorporates all of the capabilities needed for steer-by-wire, including torque feedback technology that provides repeatable performance over time and temperature and no torque at zero current. The steer-by-wire unit bolts right on to the existing gearbox that Nilfisk-Advance uses to turn the steered wheel, and fits within the existing console. Nilfisk-Advance engineers adjusted the torque feedback to simulate the hydraulic steering systems that many customers are used to. They configured the unit to provide fewer lock-to-lock steering wheel turns than are required by most hydraulic systems to reduce the amount of operator effort. They also decreased the level of steering sensitivity when the vehicle is going straight in order to make it easier for the operator to keep the vehicle on a straight path.
