RU31538U1 - Combination of vehicle electronic devices with signal transmission via interface bus and indicator diagnostics - Google Patents

Description

wiring harness for any number of indicators and indicator devices used.Jfc

The specified task in the proposed device is achieved by the fact that an additional microprocessor is introduced to process the input signals and control indicators, and the input signals are received via the interface bus.

The above set of features in comparison with the prior art allows us to conclude that the claimed technical solution meets the criterion

novelty. The set of distinctive features leading to the solution of the problem follows from the prior art, therefore, the claimed technical solution meets the criterion of inventive step.

The invention is illustrated by the drawing shown in figure 1. and consists of a microprocessor 1 for processing the signal of the bus driver, controlling the buffer devices 5 and their diagnostics, bus driver 2, which is a signal transceiver and matching signal levels of the bus and the microprocessor 1, and when exchanging information on the interface bus

one of the protocols, for example LIN, CAN or J1850, connector 3, which is standard for any number of input signals and displayed parameters, fault indicator 4, as well as buffer converters 5, capable of transmitting a signal to the microprocessor to diagnose their operability, should be used. Indicators and indicator devices 6 may be of any type.

The combination of the car’s electronic devices with signal transmission via the interface bus and indicator diagnostics works as follows: When a control command is sent to the interface input of the connector, the signal is converted by the transceiver 2 and fed to microprocessor 1, where

decrypted. Depending on the address transmitted in the command, the microprocessor generates a control signal to the corresponding indicator device 6. After

This microprocessor analyzes the execution of the issued command. In the event that the command is executed correctly, the microprocessor enters the standby mode of the next command. If - the command was not an indicator device

completed, as reported by the microprocessor buffer device 5, is

switching on the fault indicator 4 on the front panel of the instrument cluster with

indicating a faulty device. In addition, the microprocessor generates a fault code and transmits it through the transceiver 2 to the interface bus for

subsequent display by external or internal test - diagnostic equipment.
