Embodiment Construction

[0038] The application will be described in further detail below in conjunction with the accompanying drawings.

[0039] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0040] Memory may include non-permanent storage in computer-readable media, in the form of random access memory (RAM) and / or nonvolatile memory, such as read-only memory (ROM) or flash memory (flashRAM). Memory is an example of computer readable media.

[0041] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), sta...

Abstract

The invention provides a sound prompting method and equipment for low speed driving, and a vehicle. The method comprises the following steps: acquiring the external environmental sound pressure levelof the vehicle; when the driving speed of the vehicle is smaller than a preset driving speed threshold value, determining a target sound pressure level according to the external environmental sound pressure level; and carrying out sound prompting according to the target sound pressure level. The method determines the sound pressure level of a prompt sound sent by the vehicle based on the externalenvironmental sound pressure level to achieve sound prompt which is adjusted actively based on change of environmental noises, so that the effect of sound prompting is improved in a relatively noisy environment is achieved and residents are prevented from being distributed in a relatively quiet environment.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a technology for sound prompting when driving at a low speed. Background technique [0002] Compared with traditional cars, electric vehicles have no exhaust gas, low noise and are more environmentally friendly, and have been vigorously promoted. But on the other hand, electric vehicles are too quiet when running, especially when driving at low speeds, they may be undetectable by pedestrians and pose a threat to the safety of pedestrians (especially the blind, the elderly, children, etc.). One solution is to make the electric car emit a sound to remind pedestrians to pay attention to safety, but there is a problem that the sound reminder is not effective in a noisy environment (such as a downtown area), and the sound may become ineffective in a quiet residential area. Necessary noise disturbs the people. Contents of the invention [0003] In view of the problems in th...
