The invention provides a brake-by-wire system, a brake-by-wire method and a vehicle. The brake-by-wire system includes: a brake line; the brakes are arranged in one-to-one correspondence with the wheels and are connected with the brake pipeline; a vehicle information acquisition unit; an infusion line; the hydraulic driving type brake master pump is connected with the liquid conveying pipeline and the brake pipeline; the electromagnetic valve is arranged on the liquid conveying pipeline; the electronic brake control unit is connected with the vehicle information acquisition unit and the electromagnetic valve, and is used for obtaining target brake pressure required by the brake pipeline based on the vehicle driving information, and controlling the electromagnetic valve to be opened when the brake pressure in the brake pipeline is smaller than the target brake pressure; brake fluid in the liquid conveying pipeline enters the brake pipeline through the hydraulic drive type master pump so as to adjust the brake pressure in the brake pipeline, and when the brake pressure in the brake pipeline is equal to the target brake pressure, the electromagnetic valve is controlled to be closed. The brake-by-wire system is low in cost and has a wide application prospect.
本发明提供一种线控制动系统、线控制动方法及车辆。线控制动系统包括:制动管路;多个制动器,与车轮一一对应设置,并均与制动管路相连接;车辆信息采集单元;输液管路;液压驱动式制动总泵,与输液管路及制动管路相连接;电磁阀,设置于输液管路上;电子制动控制单元,与车辆信息采集单元及电磁阀相连接,用于基于车辆行驶信息得到制动管路所需的目标制动压力,在制动管路中的制动压力小于目标制动压力时,控制电磁阀打开,使得输液管路内的制动液经由液压驱动式总泵进入制动管路内,以调节制动管路内的制动压力,并在制动管路中的制动压力等于目标制动压力时,控制电磁阀关闭。本发明的线控制动系统成本较低,具有广阔的应用前景。
