VEHICLE STEERING SUPPORT DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18392603 titled 'VEHICLE STEERING SUPPORT DEVICE

The patent application describes a steering support device that includes a torque applying device, a steering torque sensor, and a control unit.

  • The torque applying device applies control torque to the steering transmission system between the steering wheel and the steered wheel.
  • The steering torque sensor is located in the steering transmission system to detect torque.
  • The control unit determines if the driver is not holding the steering wheel when the detected torque is less than a reference value.
  • The control unit adjusts the reference value based on the direction of the torque input to the steering torque sensor.

Potential Applications: - Automotive industry for advanced driver assistance systems - Autonomous vehicles for enhanced safety features

Problems Solved: - Ensures driver engagement with the steering wheel for safety - Improves overall control and stability of the vehicle

Benefits: - Increased safety for drivers and passengers - Enhanced control and responsiveness in steering

Commercial Applications: Title: Advanced Steering Support Device for Automotive Safety Systems This technology can be utilized in the development of advanced driver assistance systems for commercial vehicles, enhancing safety features and improving overall vehicle control. The market implications include increased demand for autonomous driving technologies and safety enhancements in the automotive industry.

Questions about the technology: 1. How does the steering torque sensor detect torque input accurately? 

  The steering torque sensor is designed to measure the torque applied to the steering system accurately by detecting the force exerted on the steering wheel.

2. What are the potential implications of adjusting the reference value based on the direction of torque input? 

  By adjusting the reference value based on the direction of torque input, the system can differentiate between intentional steering input from the driver and external forces on the steering system.


Original Abstract Submitted

A steering support device including: a torque applying device configured to apply control torque to a steering transmission system between a steering wheel and a steered wheel; a steering torque sensor provided in the steering transmission system between the steering wheel and the torque applying device; and a control unit configured to determine that the driver is not holding the steering wheel when the torque Ts detected by the steering torque sensor is less than the reference value Tsc. The control unit sets a reference value Tsc to a larger value when determining that torque is input to the steering torque sensor from the steered wheel side than when determining that torque is input to the steering torque sensor from the steering wheel side.
