Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] refer to figure 1 , the present invention is a hardware-in-the-loop simulation test bench that integrates a vehicle brake-by-wire system and a steer-by-wire system. Good real-time performance can realize real-time communication between vehicle dynamics model, vehicle control algorithm, brake-by-wire system, steering-by-wire system and various sensors under various driving conditions.

[0026] In order to solve the above-mentioned technical problems, the present invention utilizes Matlab / xPC Target, RTW real-time tool and signal acquisition card to independently develop a brake-by-wire system and a hardware-in-the-loop simulation test bench for a steer-by-wire system. The test bench consists of a brake-by-wire system and a steering-by-wire system. Brake-by-wire system and steering-by-wire system are divided into software part, real-time platform, signal processing part...

Abstract

The invention discloses a brake-by-wire and steer-by-wire hardware-in-the-loop test bench for a vehicle. The test bench integrates a brake-by-wire system and a steer-by-wire system into a whole, and 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 communication system; 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; and the hardware part comprises a rotary angle sensor (12), a torque transducer (13), an opposite rotary motor (16), a steering resistance sensor (21), a steering actuating motor (18), an EMB actuator controller, and EMB actuator, a clamping 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, the invention relates to a hardware-in-the-loop simulation test bench integrating a brake-by-wire system and a steering-by-wire system. Background technique [0002] With the rapid development of automobile technology, efficient and energy-saving wire control technology (x-by-wire) has been applied to the automobile field. The control-by-wire system can significantly improve the system response speed and response accuracy, improve vehicle dynamics, and further enhance vehicle driving safety and handling stability. In addition, the control-by-wire system can simplify the structure of the vehicle system, reduce the cost in the process of vehicle design, manufacture, and maintenance, save space in the vehicle, and reduce the weight of the vehicle. Brake-by-wire (BBW for short) and steer-by-wire (SBW for short), as representatives of automotive control-by-wire system...
