A multifunctional vehicle central control system

Abstract

The invention relates to a multifunctional vehicle central control system which comprises a control unit, a display screen and a signal transceiving device. The control unit comprises a capacitive touch screen controller, a vehicle navigation control module and a microcontroller, the display screen comprises a projection capacitive touch display screen connected with the capacitive touch screen controller and a capacitive touch sensing switch connected with the microcontroller, and the signal transceiving device transmits signals collected by a vehicle related accessory system sensor to the control unit; the capacitive touch screen controller can convert transverse and longitudinal position original analog signals output by the projection capacitive touch display screen into data flow composed of multiple X and Y coordinate points and transmit the data flow to a DSP (digital signal processor) controlling and processing module and a central processing unit to calculate an accurate position of a body on the projection capacitive touch display screen and decode the accurate position into corresponding gesture indication. The multifunctional vehicle central control system is high in touch sensitivity and supportive of multipoint touch, and comfort of a vehicle and attractiveness of upholstery are improved to a great extent.

Description

technical field [0001] The invention relates to an automobile auxiliary device, in particular to a multifunctional vehicle central control system. Background technique [0002] In traditional vehicles, in order to enable the driver and passengers to know the status of the vehicle and control various functions of the vehicle at any time, it is often equipped with various complex control systems. For example: navigation system, entertainment system, air-conditioning system, and interior environment regulation system. As one of the most important ways of interaction between the driver or passenger and the vehicle, the vehicle's central control interface is crucial to the driver's or passenger's operability and comfort. On the one hand, an overly complex or poorly designed vehicle central control interface may distract the driver during driving; on the other hand, the aesthetics of the vehicle central control interface also has a potential impact on vehicle sales.

AI Technical Summary

Problems solved by technology

Resistive touch screens and single-touch capacitive touch screens have disadvantages such as single control gesture function, low touch accuracy, and insufficient response.

[0005] Existing car navigation and entertainment control devices are mostly limited to playing radio, DVD or songs in terms of multimedia entertainment

At the same time, in terms of mobile phone interconnection, it is only connected through Bluetooth. There are no other functions except for Bluetooth calls or song playback through Bluetooth, which makes the entire system function relatively single, and the entertainment is not very strong.

[0006] Therefore, the existing technology cannot meet the needs of users, and needs to be improved and improved. A highly integrated product has become an urgent need
