The invention provides an electric control braking system and an unmanned wide-body vehicle. The electric control braking system comprises a front electric proportional relay valve, a middle-rear electric proportional relay valve and a two-position three-way electromagnetic valve. The front electric proportional relay valve and the middle rear electric proportional relay valve are communicated with the air cylinder and the front brake air chamber, and are used for inflating corresponding air pressure into the corresponding brake air chamber through the air cylinder when receiving a brake current signal, and releasing the air of the corresponding brake air chamber when receiving a release current signal; the two-position three-way electromagnetic valve is communicated with the air cylinderand the parking relay valve and used for controlling the parking relay valve to exhaust the parking air chamber when receiving a parking instruction and inflating the parking relay valve through the air cylinder when receiving a parking release instruction so that the parking relay valve can inflate the parking air chamber. According to the invention, autonomous braking, parking and emergency braking of the unmanned wide-body vehicle can be realized, or braking, parking and emergency braking control of a remote terminal can be accepted.
本发明提供一种电控制动系统和无人驾驶宽体车,该电控制动系统包括前电比例继动阀、中后电比例继动阀以及二位三通电磁阀;前电比例继动阀以及中后电比例继动阀连通至储气筒以及前制动气室,用于在接收到制动电流信号时通过储气筒向相应的制动气室进行相应气压的充气,在接收到释放电流信号时释放相应的制动气室的空气;二位三通电磁阀连通至储气筒以及驻车继动阀,用于在接收到驻车指令时控制驻车继动阀进行驻车气室排气,在接收到驻车释放指令时通过储气筒向驻车继动阀充气,以使所述驻车继动阀进行驻车气室充气。本发明可实现无人驾驶宽体车的自主制动、驻车和应急制动,或接受远程端的制动、驻车和应急制动控制。
