Problems solved by technology

[0004] However, when only sound is used as the condition for judging braking, misjudgment may occur, and since the existing method directly brakes after making judgments, there is no room for cancellation, which will lead to problems in special working conditions such as expressways. rear car crash hazard
And the existing sound control braking method needs to spend a long time for the braking of the vehicle

Embodiment 1

[0030] figure 1 It is a flow chart of a pre-increasing control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of pre-increasing the vehicle brake system according to the driver's voice information. This method can be controlled by the pre-increasing device, the pre-increasing control device may be implemented by software and / or hardware, and the pre-increasing control device may be configured on a computing device, specifically including the following steps:

[0031] S101. Acquire voice information, and determine a voice recognition result according to the voice information.

[0032] Wherein, the sound information can be understood as the voice information of the driver of the vehicle. Optionally, the sound information can be obtained by the sound sensor installed on the reverse disc, and the sound collected by the sound sensor can be converted into a digital signal that can be used for vehicle CAN line communication. ...

Embodiment 2

[0042] figure 2It is a flow chart of a pre-increasing control method provided by Embodiment 2 of the present invention. The technical solution of the present embodiment is further refined on the basis of the above-mentioned technical solution, and specifically includes the following steps:

[0043] S201. Acquire sound information.

[0044] Specifically, the driver's voice is acquired through one or more sound sensors installed in the vehicle, and the converted voice signal is determined as the acquired voice information.

[0045] Exemplary, image 3 An example diagram of the distribution of a sound sensor provided in the embodiment of the present invention, such as image 3 As shown, three sound sensors are installed on the steering wheel, and the angle between the sound sensors is 120°. Since the steering wheel is located directly in front of the driver, it is more convenient to collect the driver’s voice. Redundancy of sound signal collection to avoid failure to collect...

Embodiment 3

[0067] Figure 4 It is a structural schematic diagram of a pre-increasing control device provided by Embodiment 3 of the present invention. The pre-increasing control device includes: a voice recognition module 31, a vehicle state acquisition module 32 and a pre-increasing control module 33.

[0068] Wherein, the sound recognition module 31 is used to obtain sound information, and determines the sound recognition result according to the sound information; the vehicle state acquisition module 32 is used to obtain the vehicle state if the sound recognition result is a successful recognition; the pre-pressurization control module 33 , configured to determine pre-increasing control information when the vehicle state satisfies a control condition, and control the vehicle brake system to perform pre-increasing according to the pre-increasing control information.

[0069] The technical solution of this embodiment solves the problem that when the vehicle brakes only by sound and misju...

Abstract

The embodiment of the invention discloses a pre-pressurization control method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring sound information, and determining a sound recognition result according to the sound information; if the voice recognition result is that recognition succeeds, acquiring the vehicle state; and when the vehicle state meets a control condition, determining pre-pressurization control information, and controlling a vehicle braking system to conduct pre-pressurization according to the pre-pressurization control information. According to the technical scheme, the braking system can be pressurized in advance when a driver difficultly judges whether braking is needed or not, the vehicle braking system is controlled through sound to conduct pre-pressurization instead of directly controlling the braking system to conduct braking, and a problem that when a vehicle conducts braking judgment only through sound to generate misjudgment, traffic accidents are easily caused due to direct braking is solved, a revocation space is provided for an instruction generated due to misjudgment, the braking time and the braking distance are shortened, and the safety of vehicle driving is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, and in particular to a pre-charging control method, device, vehicle and storage medium. Background technique [0002] With the improvement of people's living standards, the number of cars in my country has increased year by year, making the traffic environment increasingly tense, while the annual number of new drivers has also increased by leaps and bounds, making the overall driving level not optimistic. Novice drivers often have inaccurate judgments on braking distance and braking time during driving, which seriously affects traffic safety. [0003] In order to prevent novice drivers from misjudging the braking distance and braking time, as well as being unable to step on the braking device to the bottom due to reasons such as the driver's unskilled operation and emotional tension, a passing sound is proposed in the prior art. The method for controlling the br...
