The invention discloses a fault detection method of a vehicle braking system, a fault removal method of the vehicle braking system, a drive-by-wire chassis and a vehicle, and relates to the technical field of automatic driving. The fault detection method of the vehicle braking system comprises the following steps: acquiring braking air pressures of a plurality of braking units; receiving a first brake request signal, the first brake request signal including brake deceleration; and when at least one of the brake air pressures of the brake unit is larger than a first threshold value x0 and the brake deceleration is 0, an abnormal brake signal is output. According to the fault detection method of the vehicle braking system, the abnormal braking phenomenon of the braking system can be found, and the abnormal braking signal is output.

    一种车辆制动系统的故障检测方法、一种车辆制动系统的故障解除方法、一种线控底盘及一种车辆,涉及自动驾驶技术领域。车辆制动系统的故障检测方法,包括:获取多个制动单元的制动气压;接收第一制动请求信号,第一制动请求信号包括制动减速度;在制动单元的制动气压中的至少之一大于第一阈值x0,且制动减速度为0时,输出异常制动信号。本公开的车辆制动系统的故障检测方法能够发现制动系统的制动异常现象,并输出异常制动信号。
