The actual displacement of liquid and the difference of theoretical displacement；And display device 330, for showing the row of brake fluid according to above-mentioned difference
Measure prompt information.It i.e. when driving can be with real-time detection brake fluid discharge capacity, by comparing the current practical row of brake fluid
In safe range whether amount and theoretical displacement, the actual displacement for determining current brake liquid, according to different differences, show different
Prompt information, with prompt driver carry out further operating.
Specifically, in an embodiment in the disclosure, as shown in Fig. 2, the first detection device 310 may include:
First detection module 311, for detecting the stroke of current brake device piston 1；And first computing module 312, for according to working as
The actual displacement of current brake liquid described in the climb displacement of front brake piston 1.It i.e. in the disclosure, can be living by brake
The actual displacement of the climb displacement current brake liquid of plug 1.Specifically, first detection module 311 includes being arranged in brake caliper
