Embodiment Construction

[0031] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art should understand that hardware manufacturers may use different terms to refer to the same element. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".

[0032] Please refer to figure 2 , figure 2 is a simplified block diagram of a malfunction system 200 for a vehicle malfunction display according to a first embodiment of the present invention. The malfunctioning system 200 includes: an in-vehicle system 202 , a sensor 204 , a display system 206 , a control unit 208 and a graphics processing unit 210 . The in-vehicle system 202 can be an engine management system, an ignition sys...

Abstract

The present invention provides a function safety system for a vehicle malfunction display is disclosed. The function safety system comprises: an automotive system, a sensor, a display system, a control unit, and a graphics processing unit (GPU). The sensor is coupled to the automotive system, and utilized for detecting whether the automotive system has at least a malfunction. The control unit is coupled to the sensor and directly connected to the display system, and utilized for indicating the display system when the sensor detecting the automotive system has the at least a malfunction. The GPU is coupled to the display system, and utilized for performing information transmission for the display system.

Description

technical field [0001] The invention relates to a malfunction system, in particular to a malfunction system for a vehicle malfunction display. Background technique [0002] Please refer to figure 1 , figure 1 Is a simplified block diagram of a prior art malfunction system 100 for a vehicle malfunction display. The malfunctioning system 100 includes: an in-vehicle system 102 , a sensor 104 , a display system 106 , a control unit 108 , and a graphics processing unit (GPU) 110 . The sensor 104 is coupled to the vehicle system 102 and is used for detecting whether the vehicle system 102 fails. The graphics processing unit 110 is coupled between the display system 106 and the control unit 108 . When the sensor 104 detects that the in-vehicle system 102 fails, the control unit 108 will send a signal to notify the graphics processing unit 110, and the graphics processing unit 110 will integrate the corresponding failure image into the driving information (driving inforamtion) a...
