A multifunctional vehicle central control system

Abstract

The invention relates to a multifunctional vehicle central control system, which includes a control unit, a display screen and a signal transceiver. The control unit includes a capacitive touch screen controller, a vehicle navigation control module and a microcontroller. The display screen includes a capacitive touch screen controller connected to the The projected capacitive touch display and the capacitive touch sensing switch connected to the microcontroller; the signal transceiver device transmits the signals collected by the vehicle-related accessory system sensors to the control unit; the capacitive touch screen controller can output the projected capacitive touch display The original analog signals of the horizontal and vertical positions are converted into a data stream composed of multiple X and Y coordinate points and sent to the DSP control and processing module and the central processor to calculate the precise position of the limb on the projected capacitive touch display and Decode it into the corresponding gesture indication. The invention has high touch sensitivity, supports multi-point touch, and greatly increases the comfort of the vehicle and the aesthetics of the interior.

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
