Basic Study on the Effect of Driver Condition on Steering Burden
摘要
With the widespread use of steer-by-wire in automobiles, research is being conducted on high steering gear ratio systems that reduce the burden on the driver, which enables steering with high sensitivity. However, this decreases the resolution during steering and worsens operability, making steering operation more difficult. In addition, if the amount of steering operation and the magnitude of steering reaction torque are not appropriate for the driver, it may cause operation errors. In a highly sensitive steering system, a small change in steering reaction torque has a large potential to affect the driver. The driver’s steering burden varies depending on conditions, so it is not always possible to reduce the steering burden. Therefore, we evaluated the driver’s steering burden on different days and examined the effect of steering reaction force torque on the steering burden. The results confirmed that the deviation of the burden increases as the load increases.
