背景技术
随着汽车智能化的发展，越来越多的车辆的制动系统开始采用集成式制动控制(Integrated Brake Control，IBC)单元的形式。在IBC开发完成后，需要对IBC的性能进行在环台架试验，以确保IBC投入使用时，能够满足相应的制动性能。
由于汽车主机厂会同时开发多个车型，因此会存在多个车型IBC同时参与开发的情况。因此，对IBC的性能进行在环台架试验的试验台需要兼顾多个IBC的试验。相关技术中，当需要进行一个IBC的试验时，将该IBC装在试验台上，使其与制动系统负载连接，在对测试模块进行制动系统排气，以及试验调试后，对该IBC进行测试；当该IBC测试完成后，会将该IBC拆下，换装下一IBC，使得下一IBC与制动系统负载连接，此时需要重新进行制动系统排气，以及重新进行试验调试。如此，在对不同IBC进行测试时，需要耗费大量的人力及时间，不满足短周期的产品开发方式。

示例性的，图2是本申请实施例提供的另一种制动系统试验台的结构框图，图2中与图1中相同之处可参照上述对图1的描述，在此不再赘述，此处仅对图2中与图1中不同之处进行示例性的说明。如图2所示，位置调节模块40设置为控制N个制动系统承载模块20沿第一方向X运动。此时，在对N个制动系统承载模块(21、22、…、2N)承载和固定的制动系统(11、12、…、1N)进行性能测试时，可通过位置调节模块40控制N个制动系统承载模块(21、22、…、2N)沿第一方向X运动，而测试模块30保持不动，使得每个制动系统(11、12、…、1N)的输入推杆1011依次与测试模块30连接，以能够依次对N个制动系统(11、12、…、1N)进行性能测试。如此，在对多个制动系统进行性能测试时，同样无需频繁拆装制动系统，且只需在试验开始时对测试模块的制动系统进行一次排气和试验调试即可，无需针对每个制动系统重复进行排气和试验调试，从而能够节省人力及时间，满足短周期的产品开发方式。
在上述实施例的基础上，可选的，图3是本申请实施例提供的又一种制动系统试验台的结构框图，如图3所示，位置调节模块40不仅能够控制测试模块20沿第一方向X运动，还能够控制N个制动系统承载模块(21、22、…、2N)沿第一方向X运动。此时，位置调节模块40包括动力系统调节模块41和制动系统调节模块42；动力系统调节模块41设置为控制测试模块30沿第一方向X运动；制动系统调节模块42设置为控制N个制动系统承载模块(21、22、…、2N)沿第一方向X运动。
在对其中一制动系统承载模块上的制动系统进行性能测试，例如对第i制动系统承载模块上的第i制动系统进行性能测试时，动力系统调节模块41可控制测试模块30沿第一方向X的正向方向+X运动，而制动系统调节模块42控制N个制动系统承载模块(21、22、…、2N)沿第一方向X的负向方向-X运动，直至第i制动系统的输入推杆1011与测试模块30连接，使得测试模块30能够向第i制动系统的输入推杆1011提供测试信号，以对i制动系统进行性能测试。如此，动力系统调节模块41和制动系统调节模块42相互配合，分别控制测试模块30和N个制动系统承载模块(21、22、…、2N)沿相反的方向运动，以使测试模块30快速与对应的制动系统10连接，从而能够节省测试时间，提高 测试效率；同时，动力系统调节模块41和制动系统调节模块42分别控制测试模块30和N个制动系统承载模块(21、22、…、2N)沿相反的方向运动，此时通过差分的原理，能够使动力系统调节模块41控制测试模块30运动的位移偏差与制动系统调节模块42控制N个制动系统承载模块20运动的位移偏差相互抵消，从而能够更加准确地控制测试模块30和N个制动系统承载模块20的位移量，使得测试模块30与对应的制动系统10准确连接，进而能够提高测试效率和测试准确度；此外，在动力系统调节模块41和制动系统调节模块42分别控制测试模块30和N个制动系统承载模块(21、22、…、2N)沿相反的方向运动时，还有利于减小制动系统试验台在X方向的尺寸，从而有利于减小制动系统试验台的体积。

图5是本申请实施例提供的另一种制动系统试验台的立体结构示意图，结合参考图4和图5，在进行客观性能测试时，制动踏板311处于拆卸状态，即制动踏板311未与任何制动系统(11、12、13)的输入推杆1011连接；此时，动力系统调节模块41控制作动缸底座321沿第一方向X运动，以使作动缸322与相应的制动系统(11、12或13)的输入推杆1011连接且同轴；外部控制器(图中未示出)会向作动缸322发送相应的控制信号，使得作动缸322动作，向对应制动系统(11、12或13)的输入推杆1011传递动能，使得输入推杆1011接收到作动缸322传递的动能时做出相应的反映，以使IBC总成101控制制动负载102做出相应的动作，通过相应的传感器(例如压力传感器、夹紧传感器等)检测制动负载102的动作，并反馈相应的传感器信号至外部控制器，使得外部控制器根据其所接收到的传感器信号确定出对应制动系统(11、12或13)的客观制动性能。其中，在动力系统调节模块41控制作动缸底座321沿第一方向X运动至作动缸322与相应的制动系统(11、12或13)的输入推杆1011同轴时，还可以在输入推杆1011与作动缸322的接触位置设置相应的夹具，使得作动缸 322通过夹具与输入推杆1011连接，以确保作动缸322能够与输入推杆1011的连接稳定性。
而在进行主观性能测试时，可将制动踏板311连接于相应制动系统(11、12或13)的输入推杆1011处，由测试员踩踏制动踏板311，使得制动踏板311向对应制动系统(11、12或13)的输入推杆1011传递动能，使得输入推杆1011接收到制动踏板311传递的动能时做出相应的反映，以使IBC总成101控制制动负载102做出相应的动作，并通过相应的传感器(例如压力传感器、夹紧传感器等)检测制动负载102的动作，反馈相应的传感器信号至外部控制器，使得外部控制器根据其所接收到的传感器信号输出对应制动系统(11、12或13)的测试结果，以使测试员能够根据外部控制器输出的测试结果确定出对应制动系统(11、12或13)的主观制动性能。

此外，设置于座椅底座312上的座椅313还能够沿第二方向Y运动，以调节座椅313与输入推杆1011在第二方向Y上的距离，从而在进行主观性能测试时，能够根据测试员的需求对座椅313的位置进行调节，以满足人体工程学尺寸。

相应的，继续参考图4，N个制动系统承载模块20在第一方向X上的宽度相同，且在第一方向X上，相邻两个制动系统承载模块20之间的间距相同且为固定值。如此，制动系统调节模块42会控制N个制动系统承载模块20沿同一方向同时运动。
