Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0037] Such as Figure 1-3 As shown, the present invention provides an electric steering-by-wire device for an unmanned vehicle, which includes a steering motor 110; torque. Wherein, the end surface of the steering motor 110 is fixedly connected to the case cover 124 of the spur gear reduction case 120 by bolts. The input shaft and the output shaft of the spur gear reducer 120 are respectively connected to the casing of the spur gear reducer 120 through bearings. The driving gear 121 of the spur gear reduction box 120 is connected with the output shaft of the steering motor 110 through a flat key, and the driving gear 121 is meshed with the driven gear 122 of the spur gear reduction box 120 for transmission. The driven gear 122 is connected with the output shaft of the spu...

Abstract

The invention discloses an unmanned automobile electric drive-by-wire steering device. The device comprises a steering motor, a straight gear reduction gearbox connected with an output shaft of the steering motor through a driving gear, a bevel gear speed reducer connected with an output shaft of the straight gear reduction gearbox through a bevel driving gear, and a steering transmission shaft with one end penetrating through the bevel gear speed reducer and connected with a driven gear of the bevel gear speed reducer. By the adoption of the unmanned automobile electric drive-by-wire steeringdevice, the motor is adopted for supplying power, the occupied space is small, universality is strong, the torque is large, and accurate control over steering can be achieved. The invention providesan unmanned automobile steering control method based on the unmanned automobile electric drive-by-wire steering device, the rotation angle of the steering transmission shaft is controlled in the vehicle traveling process through a fuzzy control method, and steering control of a vehicle is more accurate.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicle control, and in particular relates to an electric control-by-wire steering device and a steering control method for an unmanned vehicle.
