Abstract

The invention discloses a control method of a distributed electric redundant steer-by-wire teaching mechanism. The distributed electric redundant steer-by-wire teaching mechanism comprises a steeringsignal input mechanism, a steering driving mechanism and a corner demonstration mechanism, and comprises a steer-by-wire driver control mode, a steer-by-wire unmanned driving mode and a fault electriccontrol redundant mode, and a worm gear reducer and a planetary gear reducer are driven by double motors to complete redundant control of steer-by-wire. The control method can simulate and restore adriver steer-by-wire function, an unmanned steer-by-wire function and an electric control redundant steer-by-wire function in a fault mode of an intelligent networked automobile. According to the control method, three working modes can be selectively set according to different teaching requirements, a traditional steering transmission mechanism is completely omitted, the complexity of the system is reduced, the collapse space of the steering system is increased, and the perspectiveness of teaching knowledge of the steering system is guaranteed. In addition, the redundant steering mechanism adopted by the control method can also provide technical reference for research, development and upgrading of the steering system of the intelligent networked 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 Control method of the system teaching institution. 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 the traditional vehicle, and can complete the specified steering action only by the motor. At the same time, due to the cancellation of the mechanical structure, the steering column ...
