Title: Simulator program for modeling and incorporating differential limit torque of differential gear, and control method therefor
Inventor: SHIBAHATA KOJI
IPC: F16H48/30
Filed: 2021-06-25
Abstract: To solve such a problem that although front-back force in opposite directions is generated in left and right tires due to friction of a differential gear between left and right wheels when starting a turn by steering a handle during travel and yaw moment, that prevents the turn, is generated, since elucidation of this relationship has been insufficient and has not been taken into consideration in a simulation program previously, simulation accuracy was bad, and therefore, appropriate method for control of a differential gear has been unknown and improvement of steering response characteristic has not been achieved.SOLUTION: A differential limit torque due to friction of a differential gear is substantially proportional to a driving torque acting on the differential gear. A model, which accurately expresses this relationship, is incorporated in a simulation calculation, thereby improving calculation accuracy. Further, at a steering initial time, the differential limit torque of the differential gear is reduced, and a restoration yaw moment, that prevents a turn, is reduced, thereby improving steering response characteristic.SELECTED DRAWING: Figure 5
