Problems solved by technology

The multi-axis steering system based on the electric cylinder is independent of the steering of each axis. When there is an abnormal operation of the steering part of a certain axis, it is very easy to cause the vehicle's wheel posture to be uncoordinated, which may cause the vehicle to not drive normally, and cause the rear group of the vehicle to turn. The transmission mechanism is damaged

Abstract

The invention discloses a chassis steering system, a safety protection method and a device. The chassis steering system includes: a steering controller, an angle recognition device, a N 1 to N n Shaft Electric Cylinder Driver, N 1 to N n Shaft electric cylinder and display terminal; the steering angle information collected by the angle recognition device and the N 1 to N n The working state of the axis electric cylinder driver is abnormally monitored. If there is abnormality in the steering angle information or the working state of any axis electric cylinder driver is abnormal, the steering angle of each steering wheel is controlled to maintain the preset safe posture, and the abnormal The information is reported to the display terminal for display, which effectively realizes the safety protection of the chassis steering system and improves the system reliability.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a chassis steering system, and a safety protection method and device applied to the chassis steering system. Background technique [0002] The chassis steering system is one of the key control systems to ensure the normal running of the vehicle. The multi-axis steering system based on the electric cylinder is independent of the steering of each axis. When there is an abnormal operation of the steering part of a certain axis, it is very easy to cause the vehicle's wheel posture to be uncoordinated, which may cause the vehicle to not drive normally, and cause the rear group of the vehicle to turn. Transmission mechanism damaged. [0003] Therefore, providing a safety protection scheme applied to the chassis steering system is an urgent problem to be solved at present. Contents of the invention [0004] The invention provides a chassis steering system, and a safety protection m...
