Abstract

The invention provides an unmanned vehicle dedicated all-line-control chassis capable of omitting a human driving mechanism. Chassis design adopts an all-electric and all-line-control design scheme torealize the all-line-control control of a driving, steering and braking system. The all-line-control chassis mainly comprises a vehicle body, wheels, a line control braking system, a line control steering system, a line control driving system, a power system and a vehicle communication system, wherein the wheels are connected with the vehicle body through a suspension system; the line control braking system, the line control steering system, the line control driving system, the power system and the vehicle communication system are fixedly installed on the vehicle body; the line control braking system controls an electronic hydraulic control system through a braking motor instruction to realize vehicle braking; the line control steering system provides a steering moment for steering wheelsthrough the steering motor; the line control driving system provides a driving moment for driving wheels through a driving motor; and the vehicle communication system comprises a CAN (Controller AreaNetwork) bus and a VCU (Vehicle Control Unit), wherein a vehicle upper layer automatic driving system is connected with the VUC through the CAN bus, and the VCU is independently connected with the line control braking system, the line control steering system and the line control driving system through the CAN bus. The all-line-control chassis has the characteristics of modularization and universalization, and can meet the use requirements of a multifunctional unmanned vehicle.

Description

Technical field [0001] The invention relates to an automobile chassis, in particular to a full-wire control chassis, and belongs to the technical field of unmanned driving and vehicle chassis. Background technique [0002] Autonomous driving technology is an important development direction of the future automobile industry, and it is also one of the important starting points for the artificial intelligence industry. An unmanned vehicle refers to a vehicle that has autonomous behavior capabilities and completely omits human driving mechanisms. It has the characteristics of intelligence, wire control, robotics, and multi-function, and is an important part of autonomous vehicles. The purpose of the use of unmanned vehicles is to replace humans in performing operational tasks, including but not limited to civilian or military tasks such as strike, combat, patrol, reconnaissance, logistics, transportation, ferrying, distribution, and cleaning. It has very broad applications in the civ...
