The invention relates to a brake system and a commercial vehicle. The brake system includes: a medium providing unit; a first brake loop the two opposite ends of which communicate with the medium providing unit, and which comprises a first sub-brake loop and a second sub-brake loop which are arranged in parallel; a service brake cylinder communicating with the first brake loop and in transmission connection with a brake; a proportional valve communicating with the first sub-brake loop and arranged upstream the service brake cylinder; a controller in communication connection with the proportional valve; a reversing valve arranged on the second sub-brake loop and in communication connection with the controller. When the proportional valve is closed, the first sub-brake loop is blocked, and the reversing valve is controlled to communicate with the second sub-brake loop, so that the brake medium can bypass the proportional valve to enter the service brake cylinder through the reversing valve. According to the brake system, the stability of the commercial vehicle is effectively improved through the braking function dual-redundancy design.

    本发明涉及一种制动系统及商用车。该制动系统包括:介质提供单元;第一制动回路,相对的两端分别连通于介质提供单元,第一回路包括并联设置的第一子制动路和第二子制动路;行车制动缸,连通于第一制动回路,且传动连接于制动器;比例阀,连通于第一子制动路,且设于汽车制动缸的上游;控制器,通讯连接于比例阀;及换向阀,设于第二子制动路,且通讯连接于控制器;其中,当比例阀关闭时,第一子制动路闭塞,换向阀受控连通第二子制动路,以使制动介质能够绕过比例阀经换向阀至行车制动缸内。该制动系统通过制动功能双冗余设计有效地提高了商用车的稳定性。
