Embodiment 1

[0063] This embodiment provides a vehicle-mounted electronic device, which includes a base 1 and a display unit 2 electrically connected to the base 1 .

[0064] The base 1 is electrically connected to the vehicle OBD interface, and is used to obtain vehicle operation status data from the vehicle OBD interface, map the vehicle operation status data into corresponding control parameters, and transmit them to the display unit 2 .

[0065] The display unit 2 is configured to receive the control parameters, and perform corresponding dynamic display according to the control parameters.

[0066] The vehicle running state data includes relevant data such as engine speed, vehicle speed, fuel quantity, and exhaust emission.

[0067] Compared with the prior art, which only displays the vehicle running state data on the screen, this embodiment maps the vehicle running state data to corresponding control parameters for driving the display unit, so that the display effect of the display un...

[0078] As an optional implementation manner, the display module 22 also includes:

[0079] The sound control module 222 is configured to control the display unit 2 to perform corresponding sound display according to the control parameters.

[0080] As an optional implementation manner, the display module 22 also includes:

[0081] The lighting control module 223 is configured to control the display unit 2 to perform corresponding lighting display according to the control parameters.

[0082] The display module described in this embodiment may include only one of the above display methods, or may include any combination of the ...

Embodiment 3

[0094] On the basis of Embodiment 1 or Embodiment 2, the vehicle-mounted electronic device described in this embodiment, the base 1 also includes a base interface 13, which is electrically connected to the first microcontroller 12, and the control parameter Transfer to the display unit 2.

[0095] The display unit 2 further includes a device interface 23 electrically connected to the second microcontroller 21 and transmitting the control parameters received from the base interface 13 to the second microcontroller 21 .

[0096] The base 1 and the display unit 2 are electrically connected through the base interface 13 and the device interface 23 .

[0097] In the vehicle-mounted electronic device described in this embodiment, as an optional implementation manner, the base interface 13 is a USB female connector, and the device interface 23 is a USB male connector.

[0098] The vehicle-mounted electronic device described in this embodiment is divided into two detachable independe...

Abstract

The invention relates to a vehicle-mounted electronic device. Vehicle operating state data are obtained from a vehicle OBD interface through a chassis, mapped into corresponding control parameters, and then transmitted to a display unit; after the control parameters are received, the display unit carries out corresponding dynamic display according to the control parameters. Compared with the prior art that the vehicle operating state data are displayed only through a screen, the vehicle-mounted electronic device has the advantages that the vehicle operating state data are mapped into the corresponding control parameters to drive the display unit, therefore, display effects of the display unit can change in real time according to different vehicle conditions, display methods are more vivid and visual, and driving experience of drivers can be improved beneficially. In addition, the vehicle-mounted electronic device is divided into two detachable independent parts, namely, the chassis and the display unit, fixing and electrical connection between the chassis and the display unit are achieved through a USB female connector and a USB male connector, and replacement operation of the display unit can be completed just through simple hot plugging.

Description

technical field [0001] The invention relates to a vehicle electronic device. Specifically, it is an on-board electronic device capable of displaying vehicle operating status data. Background technique [0002] Vehicles expand people's living space and facilitate people's lives, but they also bring corresponding social problems. As the number of vehicles continues to increase, traffic congestion is becoming more and more congested, which means that people spend more and more time in the car. A vehicle is a small, closed, and moving inner space, and at the same time, its external environment is very complicated. Drivers need to concentrate for a long time to ensure driving safety. However, if the time spent in this environment is too long, the driver's psychological and physiological aspects are more likely to produce abnormal fluctuations, which can easily induce traffic accidents. Entertaining things, such as music, humorous speech or some interesting car interior decorat...
