Hardware-in-the-loop test bench based on electromechanical braking system

Abstract

The invention discloses a hardware-in-the-loop test bench based on an electromechanical braking system, which is divided into a software part, a real-time platform, a signal processing part and a hardware part, wherein the real-time platform consists of a host and target machines 1 and 2; the host and the target machines 1 and 2 are connected by a wireless network; the signal processing part consists of first and second data acquisition cards with the model of PCL-818HD, third and fourth data acquisition cards with the model of PCL-727, a fifth data acquisition card with the model of PCI-6601 and a V/F conversion module; the first and second data acquisition cards with the model of PCL-818HD and the third and fourth data acquisition cards with the model of PCL-727 are connected with the target machines 1 and 2 by an ISA bus; the fifth data acquisition card with the model of PCI-6601 is connected with the target machine 2 by a PCI bus; and the hardware part comprises an EMB actuator controller, an EMB actuator, a force sensor, a revolution transmitter and a current sensor.

Description

technical field [0001] The invention relates to a hardware-in-the-loop simulation test bench, more specifically, it relates to a hardware-in-the-loop simulation test bench using an electromechanical braking system. Background technique [0002] With the continuous development of automobile technology, efficient and environmentally friendly brake-by-wire technology has become a research hotspot at home and abroad. Electro-mechanical Brake (EMB for short) is the most representative branch of the brake-by-wire system. It is a complete and highly integrated mechatronic device. It can comprehensively realize ABS without adding any accessories. Active safety control functions such as , TCS, ESP and EBD further enhance the maneuverability and safety of the car. Using hardware-in-the-loop technology to establish a hardware-in-the-loop comprehensive test bench based on the brake-by-wire system can realize various functions such as system development, debugging, testing, and performa...
