Displacement is correlated with, and when brake pedal displacement is a, the force value that braking clamp at least should produce is b, utilizes
The displacement of displacement transducer monitoring brake pedal, utilizes the force value of pressure sensor monitoring braking clamp, when
When brake pedal displacement is a, force value x produced by braking clamp compares with force value b preset,
Determine brake failure when x is less than b, when x is 0, brake the most malfunctioning；
Fig. 2 is the schematic diagram of a kind of brake failure decision method, as in figure 2 it is shown, the embodiment of the present invention is led to
Cross following method and determine whether brake information shows brake failure:
Step 201: obtain brake pedal position information and speed information, described brake pedal information includes the
One positional information and second position information, corresponding first speed of described primary importance, the described second position pair
Answer the second speed；
Obtain brake pedal position information by sensing devices such as displacement transducers, obtained by vehicle speed measuring instrument
Taking speed information, described primary importance, the described second position present invention are not specifically limited；The present invention is real
Execute the preferred described second position information of example and include the extreme lower position that described brake pedal can be stepped on；
Step 202: when described brake pedal moves to the described second position from described primary importance, calculates
Described first speed and the difference of described second speed, and described difference is compared with preset value；When
When described difference is less than described preset value, the display brake failure of described brake information.
Under normal condition, when described brake pedal is stepped on to the described second position by user from described primary importance
Time (i.e. brake pedal is floored), the value that speed reduces is at least n, n and includes any number, its size
Being determined by factors such as vehicle, described primary importance, road conditions, different vehicle is in different road conditions, difference first
N value under position can be obtained by modes such as experiment or theoretical implications, and the embodiment of the present invention is not done any
Limit；It is n by described default settings；Now, it is assumed that described brake pedal when described primary importance,
Described first speed is m1, and described brake pedal is when the described second position, and described second speed is m2,
