Embodiment 1

[0034] Example 1: Infrared sensor

[0035] specifically, image 3 It shows a schematic diagram of realizing manipulation detection by an infrared sensor according to an embodiment of the present invention.

[0036] Such as image 3 As shown, according to a more preferred embodiment of the present invention, such as figure 1 The illustrated manipulation detection module 104 may include:

[0037] The infrared sensor 21 is arranged around the control screen 11 of the multimedia control system 1 and close to the passenger side. Specifically, for example, the infrared sensor 21 is arranged above the control screen 11, and its probe is tilted downward to form a corresponding infrared detection area 2'(such as figure 2 In the upper right area of ​​the control screen 11).

[0038] Then, the feedback signal of the infrared sensor 21 is received by the controller (not shown in the figure), and when a moving object is detected in the infrared detection area 2', it is determined that the hand of...

Embodiment 2

[0042] Embodiment two: microwave antenna

[0043] specifically, Figure 4 It shows a schematic diagram of realizing manipulation detection through a microwave antenna according to an embodiment of the present invention.

[0044] Such as Figure 4 As shown, according to a more preferred embodiment of the present invention, such as figure 1 The illustrated manipulation detection module 104 may include:

[0045] The microwave antenna 22 is arranged inside the control screen 11 of the multimedia control system 1, and a corresponding microwave detection area 2" is formed around the control screen 11 and near the passenger side.

[0046] Then, the feedback signal of the microwave antenna 22 is received by a controller (not shown in the figure), and when a moving object is detected in the microwave detection area 2", it is determined that the hand of the passenger in the front passenger seat is approaching manipulation The screen 11 is switched to the unlocked state accordingly.

[0047] Amon...

Embodiment 3

[0050] Embodiment 3: Distance measuring device

[0051] In the first and second embodiments, the infrared sensor and the microwave antenna are used to measure whether the hand of the passenger in the front passenger seat enters the corresponding detection area, so as to confirm the distance between the hand of the passenger in the front passenger seat and the control screen. Is the distance less than or equal to the preset distance.

[0052] Therefore, as a more preferred embodiment of the present invention, a distance measuring device (not shown in the figure) can also be used to directly monitor the real-time distance between the passenger's hand and the control screen, and the real-time distance When the distance is less than or equal to the preset distance, the control screen is switched to the unlocked state.

[0053] Specifically, the distance measuring device may include: a laser distance measuring device, an ultrasonic distance measuring device, or an infrared distance measu...

Abstract

The invention provides a screen unlocking method and system. The screen unlocking method and system are applied to a vehicle-mounted multi-media control system. The screen unlocking method comprises the steps that when the situation that a vehicle is in the traveling state is detected, a control screen of the vehicle-mounted multi-media control system is set to be in the locked state; when the control screen is in the locked state, the distance between a hand of a passenger on the co-driver seat and the control screen is detected; if the distance is smaller than or equal to a preset distance, the control screen is switched to be in the unlocking state. According to the technical scheme, the control screen of the multi-media control system can be automatically locked according to the running state of the vehicle so that driving safety of a driver can be ensured; in addition, the control screen can be automatically unlocked by judging the action intention of the passenger on the co-driver seat, and therefore control convenience of the passenger on the co-driver seat is remarkably improved.

Description

Technical field [0001] The invention relates to the technical field of vehicle control, in particular to a screen unlocking method and system. Background technique [0002] At present, most cars are equipped with Multi Media Controller System (MMC) to provide services and functions such as map navigation and multimedia file playback. However, the multimedia control system is often locked during driving to avoid disturbing the driver's attention, thereby ensuring the driver's safety during driving. [0003] In order to avoid parking the vehicle every time the multimedia control system is operated (sometimes it may not be convenient to park, such as when driving on a highway), people hope that the passenger in the front passenger seat will control the multimedia control system during driving. However, in related technologies, the automatic locking of the multimedia control system is for all passengers, so that neither the driver nor the passenger in the front passenger seat can cont...
