Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] This embodiment provides a test system for a full control-by-wire chassis of an unmanned vehicle. The layout of the test system is highly integrated, the test environment is convenient to build, and the test environment is clean and beautiful.

[0027] Such as figure 1 As shown, the tested vehicle is connected to the chassis test system, which includes the chassis test execution system, cooling system, measurement and control system and human-computer interaction system.

[0028] The chassis test execution system in this embodiment includes 4 sets of execution subsystems, which are responsible for performing chassis driving and steering tests. Each executive subsystem includes a dynamometer bench and a dynamometer controller. The dynamometer bench includes a bracket, a dynamometer, a steering motor and a torque meter. The bracket can move on the ...

Abstract

The invention discloses an unmanned vehicle full drive-by-wire chassis test system, which is characterized by comprising a chassis test execution system, a measurement and control system and a man-machine interaction system, The chassis test execution system comprises four groups of execution subsystems, and each group of execution subsystem comprises a dynamometer rack and a dynamometer controller; the dynamometer rack comprises a support, a dynamometer, a steering motor and a torque meter. the dynamometer controller controls the steering motor to output the load torque, the dynamometer is pushed by the support to rotate along with steering of the chassis so as to simulate a transverse road load, and a measurement and control system is compared with an actual steering angle of the chassis, so that a steering system test is realized. and the man-machine interaction system is connected with the measurement and control system and is used for realizing interaction between the outside and the chassis test system. According to the invention, multi-working-condition, multi-execution-mechanism and multi-motion-behavior tests of the unmanned vehicle full-drive-by-wire chassis can be realized, and unmanned vehicle chassis test requirements of complex configurations such as independent driving of each wheel and independent steering of each wheel can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of vehicle chassis testing, and in particular relates to a full-wire control chassis testing system for unmanned vehicles. Background technique [0002] Unmanned vehicles can replace humans to perform civilian or military tasks such as strikes, combat, patrols, reconnaissance, logistics, transportation, ferrying, distribution, cleaning, etc., and have very broad application prospects in civilian or military fields. It is an important part of my country's new generation of army equipment development. Therefore, the development of unmanned vehicle theory and technology is of strategic significance to my country's national economic development and national defense security construction. [0003] Compared with traditional vehicles, the overall configuration, layout form, control system, and actuators of unmanned vehicles are completely different. Due to the special use function, the unmanned vehicle completely ...
