Abstract

The invention relates to an active suspension bench test measurement and control system based on a LabVIEW platform. The active suspension bench test measurement and control system comprise a to-be-tested device, a sensor calibration module, a signal acquisition module, a control signal output module, a signal preprocessing module, a measurement and control system monitoring module, a control algorithm import module and an upper computer, wherein the sensor calibration module is used for calibrating sensors for tests, the signal acquisition module is used for acquiring signals, the control signal output module is used for outputting control signals, the signal preprocessing module is used for preprocessing the signals, the measurement and control system monitoring module is used for monitoring acquired data, and the control algorithm import module is used for importing control algorithm and building relation between hardware and software. An active suspension system actuator, sensors, a controller and control algorithm are built into the complete measurement and control system, so that algorithm debugging is facilitated greatly, algorithm debugging cycle is shortened, test cost is lowered, and high reliability is achieved.

Description

technical field [0001] The invention relates to a vehicle measurement and control system, in particular to an active suspension bench test measurement and control system based on a LabVIEW platform, which belongs to the technical field of vehicle component measurement and control. Background technique [0002] As people's requirements for vehicle ride comfort and handling stability continue to increase, it is hoped that when the vehicle load, driving speed, road conditions and other driving conditions change, the vehicle can automatically adjust the stiffness of the suspension system, so the demand for active suspension of the vehicle increasing day by day. At the same time, the industry's research on active suspension systems has become more in-depth and extensive. For the active suspension system, there are various types of actuators that generate the active force, and the active control algorithms are also different. Therefore, a flexible and convenient active suspension...

Problems solved by technology

[0003] However, the current domestic suspension system measurement and control field mainly focuses on semi-active and passive suspension performance analysis, and there is no perfect active suspension measurement and control system.

Secondly, the existing measurement and control systems often focus on testing rather than controlling, mainly focusing on suspension performance testing, and the control function is relatively weak, and it is impossible to combine complex control algorithms and suspension system hardware for testing
