Embodiment 1

[0042] A method for setting the low-speed prompt sound of a pure electric vehicle, which is carried out in accordance with the following steps in sequence:

[0043] 1. Determine whether the following conditions are met at the same time. If so, short press the car instrument button to enter the low-speed prompt tone setting interface:

[0044] The vehicle key is in the ON gear;

[0045] The car instrument is in working condition;

[0046] 2. The car instrument collects the status information of the car door. If the door is closed, go to step 3;

[0047] 3. When the car meter detects that the door is opened and closed at least 3 times within 15 seconds, and the button of the car meter is pressed for more than 5 seconds, the car meter will enter the sound selection interface;

[0048] 4. Within 10 seconds, the sound number of the low-speed prompt tone set by default is 0, and each time the car instrument button is pressed once, it will switch to the low-speed prompt tone with t...

Abstract

A pure electric vehicle low-speed warning tone setting method comprises the steps that firstly, a low-speed warning tone setting interface is entered by pressing an automobile instrument key for a short time, then a sound selection interface is entered by pressing the automobile instrument key for a long time, then sound selection is completed through the automobile instrument key, and finally an automobile instrument sends a selected sound number to a low-speed warning tone device. The follow-up speed warning tone device can make corresponding sounds according to the sound numbers when the vehicle runs at a low speed. The method not only realizes stable and rapid setting of the low-speed prompt tone, but also is low in cost.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a method for setting low-speed prompt sounds of pure electric vehicles realized through automobile instrument buttons. Background technique [0002] In response to the low-speed driving safety of electric vehicles, the state issued the standard GB / T 37153-2018 "Low-speed Beeps for Electric Vehicles", which was implemented on July 1, 2019. Among them, the vehicle speed, sound level, Frequencies are specified, but specific sounds are not. At present, general vehicle manufacturers usually only set one low-speed beep sound. If you want to switch, you need to use a special tool or use the additional multimedia configuration of the vehicle to switch the sound setting, which increases the hardware cost and cannot satisfy customers. Diversification of beep sounds , Quick setup requirements. Contents of the invention [0003] The object of the present invent...
