AI Technical Summary

Technical Problem

Existing obstacle-crossing vehicles have low obstacle-crossing efficiency and poor stability when facing complex terrain. They are prone to rollover and are costly. They also cannot effectively adjust the vehicle's center of gravity and wheelbase, leading to obstacle-crossing failure or vehicle damage.

Method used

It adopts a variable configuration design, including a variable wheelbase mechanism, an active suspension mechanism, and a three-dimensional perception system. It uses three-dimensional LiDAR and industrial cameras to perceive the terrain in real time, dynamically adjust the vehicle attitude and wheelbase, and use an inertial measurement unit to predict vehicle stability, thereby achieving coordinated control of active suspension and variable wheelbase.

Benefits of technology

It improves the passability and stability of obstacle crossing vehicles, reduces mechanical impact, prevents vehicle rollover, and enhances the reliability and service life of obstacle crossing vehicles.

Abstract

The application discloses a variable-configuration obstacle-crossing vehicle, which comprises a bearing frame, a variable-wheelbase mechanism, a main suspension mechanism, a power moving mechanism and a three-dimensional sensing mechanism installed on the bearing frame; the variable-wheelbase mechanism comprises a variable-wheelbase electric cylinder, a variable-wheelbase sliding plate and a heavy-load sliding rail; the variable-wheelbase electric cylinder is fixed on the bearing frame and arranged in parallel with the moving direction of the bearing frame. The whole structure of the application has high reliability; the inertial measurement unit, the three-dimensional laser radar module and the industrial camera module installed on the bearing frame are used to realize real-time sensing of the vehicle posture and external obstacle information; based on the obtained information, an obstacle-crossing strategy suitable for the current terrain is dynamically generated; when the vehicle faces an obstacle, the suspension electric cylinder in the main suspension mechanism is controlled to actively adjust the vehicle posture, so that the obstacle is crossed; the method breaks through the limitation that the traditional obstacle-crossing method mainly depends on the friction force between the front wheels and the obstacle, and the reliability of obstacle-crossing is improved.
