Embodiment 1

[0035] Such as figure 1 As shown, a method for waking up a vehicle-mounted intelligent device is characterized in that, comprising the following steps:

[0036] S1: Simultaneously collect voice and light changes within the preset range of on-board smart devices;

[0037] S2: If the voice is collected, convert the collected voice audio into text through the semantic analysis engine, and match it with the preset wake-up word. When the matching voice is the wake-up word, wake up the on-board smart device;

[0038] If the voice is not collected, then jump to step S3;

[0039] S3: If the collected light within the preset range of the on-board smart device changes, wake up the on-board smart device;

[0040] If no change in light within the preset range of the on-board smart device is collected, skip to step and return to step S1.

[0041] In step S1, the preset range is 0-30cm.

[0042] In step S3, if the collected light within the preset range of the on-board smart device chan...

Embodiment 2

[0047] A wake-up device for a vehicle-mounted intelligent device, comprising: a voice collection module 1, a voice conversion module 2, a voice matching module 3, a wake-up trigger module 4 and a photosensitive module 5, the voice collection module 1, the voice conversion module 2, and the voice matching module 3 are electrically connected in turn, the voice matching module 3 and the photosensitive module 5 are electrically connected to the wake-up trigger module 4 respectively, and the wake-up trigger module 4 is also electrically connected to the vehicle-mounted intelligent device 6;

[0048] The voice collection module 1 is used to collect voice and send to the voice conversion module 2;

[0049] The voice conversion module 2 is used to convert the voice audio collected by the semantic analysis engine into text and send it to the voice matching module 3;

[0050] The voice matching module 3 is used for matching with the preset wake-up word, and when the voice is matched as ...

Abstract

The invention provides an awakening method and device for intelligent vehicle-mounted equipment. The awakening method comprises the steps that voice and light ray change of the intelligent vehicle-mounted equipment in a preset range are collected at the same time; if the voice is collected, the collected voice frequency is converted into characters through a semantic parsing engine, the charactersare matched with preset awakening words, and when the characters are the awakening words through matching, the intelligent vehicle-mounted equipment is awakened; if light ray change of the intelligent vehicle-mounted equipment in the preset range is collected, the intelligent vehicle-mounted equipment is awakened. According to the awakening method, on the basis of voice awakening, the light sensation awakening technology is added, the awakening action of the device is simple, the awakening success rate is increased, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the field of intelligent vehicle-mounted equipment, and more specifically, to a wake-up method and a wake-up device for a vehicle-mounted intelligent equipment. Background technique [0002] With the increasing popularity of artificial intelligence technology, various software and hardware products such as artificial intelligence companions and voice assistants have entered the daily life of the public. Especially in the car scene, various artificial intelligence voice assistants have gradually become the driver's virtual "copilot", providing convenient services for the driver during driving. At present, various in-vehicle voice assistant products use the voice wake-up method. When the user speaks a specific wake-up word, the in-vehicle voice assistant is woken up and starts recording to receive the user's next voice command. Due to the limitations of the environment in the car, this simple voice wake-up method has cer...
