Embodiment 1
[0049] figure 1 It is a flow chart of a fault detection method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing fault detection on the brake system of the vehicle. Typically, this embodiment is applicable to the situation of performing fault detection on the braking system of the self-driving vehicle. The method can be executed by a fault detection device, and the device can be realized by software and / or hardware. see figure 1 , the fault detection method provided in this embodiment includes:
[0050] S110. Acquire the current speed of the vehicle when it is detected that the vehicle is in a braking state.
[0051] Wherein, the vehicle may be an autonomous vehicle or a non-autonomous vehicle.
[0052] Optionally, to monitor the braking state of the vehicle, the pressure of the brake pedal can be detected by pressure sensing to determine whether the vehicle is in the braking state, or it can be determined whet...
Embodiment 2
[0080] figure 2 It is a flow chart of a fault detection method provided by Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments, taking the vehicle as an example of an automatic driving vehicle. see figure 2 , the fault detection method provided in this embodiment includes:
[0081] S210. When the control module of the vehicle sends a braking command, continuously record the braking state for N times, so as to ensure that the vehicle is indeed in the braking state.
[0082] Among them, N is the set braking times threshold.
[0083] S220. Record the vehicle speed of the N+1th braking state as the initial speed.
[0084] S230, then continuously record the brake pedal depth value sent by the control module for M times.
[0085] Among them, M is greater than or equal to 2, which can be set according to actual needs. If you want the accuracy of the brake pedal depth value to be higher, you can set M...
Embodiment 3
[0092] image 3 It is a schematic structural diagram of a fault detection device provided in Embodiment 3 of the present invention. see image 3 , the fault detection device provided in this embodiment includes: a current speed acquisition module 10 , a standard speed acquisition module 20 and a fault determination module 30 .
[0093] Wherein, the current speed obtaining module 10 is used to obtain the current speed of the vehicle when it is detected that the vehicle is in a braking state;
[0094] A standard speed acquisition module 20, configured to determine the standard speed of the vehicle after braking according to the current speed and the braking parameters of the vehicle;
[0095] The failure determination module 30 is configured to determine whether there is a failure in the braking system of the vehicle according to the standard speed and the actual speed of the vehicle after braking.
[0096] According to the technical solution of the embodiment of the present ...
