Problems solved by technology

Under normal circumstances, the driving speed of the vehicle is relatively fast, and the vehicle brakes through the brakes to achieve the purpose of deceleration. However, if the brake fails (such as: the brake line is loose or the brake line is too tight), it may cause serious damage. security incidents and threats to the lives of users
[0003] Based on the above reasons, it is necessary to detect the brakes of the vehicle to determine whether the brakes are faulty. In the prior art, it is usually manually detected whether the brakes of the vehicle are faulty. This method will cause a relatively large amount of manual work. larger

Embodiment 1

[0094] figure 1 A schematic flow chart of a brake fault detection method provided in Embodiment 1 of the present application, as shown in figure 1 As shown, the method includes the following steps:

[0095] Step 101. Obtain the current acceleration of the target vehicle and the current braking parameter information related to the brake handle.

[0096]Specifically, the vehicle may decelerate the vehicle through a braking system during driving, so as to achieve the purpose of braking. If there is a problem with the braking system, the vehicle cannot decelerate, or the vehicle can decelerate, but the deceleration trend (deceleration situation) will be abnormal compared with the normal situation, so in order to determine whether the braking system is faulty, it is necessary to judge Whether the vehicle has decelerated, and if so, it is necessary to further judge whether the deceleration trend matches the action of the braking system. For example, the greater the action range of...

[0151] Figure 6 A schematic structural diagram of a brake fault detection device provided in Embodiment 2 of the present application, as shown in Figure 6 As shown, the device includes:

[0152] The acquisition unit 61 is used to acquire the current acceleration of the target vehicle and the current braking parameter information related to the brake handle;

[0153] An acquisition unit 62, configured to acquire the target acceleration range corresponding to the current braking parameter information related to the brake handle according to the preset corresponding relationship between the braking parameter information and the acceleration range;

[0154] The detection unit 63 detects whether the brake of the target vehicle fails according to the acquired current acceleration of the target vehicle and the target acceleration range.

[0155] In a feasible implementation, the current brake parameter information related to the brake handle includes at least one of the following...

Embodiment 3

[0186] Figure 10 A schematic structural diagram of an electronic device provided in Embodiment 3 of the present application, including: a processor 1001, a storage medium 1002, and a bus 1003, and the storage medium 1002 includes such as Figure 6 In the device shown, the storage medium 1002 stores machine-readable instructions executable by the processor 1001. When the electronic device runs the above positioning method, the processor 1001 and the storage medium 1002 are connected through a bus 1003 communication, the processor 1001 executes the machine-readable instructions to perform the following steps:

[0187] Obtain the current acceleration of the target vehicle and the current braking parameter information related to the brake handle;

[0188] Acquiring the target acceleration range corresponding to the current braking parameter information related to the brake handle according to the preset corresponding relationship between the braking parameter information and the a...

Abstract

The embodiment of the invention provides a brake fault detection method and device. The method comprises the steps: obtaining a current acceleration of a target vehicle and current brake parameter information related to a brake handle; acquiring a target acceleration range corresponding to the current brake parameter information related to the brake handle according to a preset corresponding relationship between the brake parameter information and the acceleration range; and according to the obtained current acceleration of the target vehicle and the target acceleration range, detecting whether the brake of the target vehicle has a fault or not. Through the method, manual participation is not needed so that reduction of a manual workload is facilitated.

Description

technical field [0001] The present application relates to the technical field of automation, in particular, to a brake fault detection method and device. Background technique [0002] With the improvement of people's living standards, various means of transportation have become the choice of people's daily travel. Under normal circumstances, the driving speed of the vehicle is relatively fast, and the vehicle brakes through the brakes to achieve the purpose of deceleration. However, if the brake fails (such as: the brake line is loose or the brake line is too tight), it may cause serious damage. security incidents and threats to the lives of users. [0003] Based on the above reasons, it is necessary to detect the brakes of the vehicle to determine whether the brakes are faulty. In the prior art, it is usually manually detected whether the brakes of the vehicle are faulty. This method will cause a relatively large amount of manual work. larger. Contents of the invention ...
