Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The invention is mainly used for the mechanism teaching of the steering-by-wire system in middle and higher vocational colleges, and simulates the electric steering-by-wire function, the steering torque simulation feedback function and the electric redundant steering function of the intelligent networked vehicle through the cooperation of the mechanism and the motor.

[0029] As shown in the accompanying drawings, a distributed electric redundant steering-by-wire teaching mechanism of the present invention includes:

[0030]Steering signal input mechanism. The steering signal input mechanism includes a steering stepped shaft 2 arranged in the horizontal direction. A steering wheel 1 is fastened to the right end of the steering stepped shaft 2 through spline fastening. 2 The left side is connected with the steering angle gear 3 through ...

Abstract

The invention discloses a distributed type electric redundance steer-by-wire teaching mechanism. The distributed type electric redundance steer-by-wire teaching mechanism comprises a steering signal inputting mechanism, a steering driving mechanism and a turning demonstrating mechanism. Through a dual-motor-driven worm-and-gear speed reducer and a planet gear speed reducer, steer-by-wire redundance control is finished. The distributed type electric redundance steer-by-wire teaching mechanism disclosed by the invention also can simulate and restore a driver steer-by-wire function, an unmanned driving steer-by-wire function and an electronically-controlled redundance steer-by-wire steering function in an error mode of an intelligent networking automobile. According to the distributed type electric redundance steer-by-wire teaching mechanism disclosed by the invention, three working modes can be set selectively according to different teaching needs, conventional steering transmission mechanisms are completely eliminated, the complexity degree of a system is reduced, a washboarding space of a steering system is enlarged, and the perspectiveness of teaching knowledge of the steering system is ensured. In addition, the adopted redundance type steering mechanism also can provide a technical reference for upgrading of research and development on the steering system of the intelligent networking automobile.

Description

technical field [0001] The present invention relates to the field of steering-by-wire teaching for intelligent networked vehicles, and in particular to a redundant steering-by-wire system capable of restoring pure electric steering of intelligent networked vehicles, steering-by-wire functions under driverless conditions, and electric steering functions in failure modes system teaching institutions. Background technique [0002] The steer-by-wire system is one of the most important systems for the safety assurance of intelligent networked vehicles, which is related to the intelligence of the steering system and the intelligence of the whole vehicle. The electric steering by wire system completely cancels the connection of the steering column and other mechanical structures on traditional vehicles, and only relies on the motor to complete the specified steering action. To the driver's personal safety in the event of a collision. The electric steering-by-wire system must have...
