Cluster Variant Coding

As we have more options (ESC, MDPS etc.) in the car, the dashboard now has more information to display depending on the chosen options.

For this reason, we need to learn which options the vehicle has when replacing the dashboard.

To address this issue, a course of learning based on the option required for the vehicle when replacing the dashboard should be carried out.

This is called Variant Coding.

Function

1.

High speed CAN communication (C-CAN)

Custom Function : car seats linked to getting on/off motion, Welcome Light

LDWS : Lane Departure Warning System

SPAS: Smart Parking Assist System

2.

Low speed CAN communication (M-CAN)

AV : Audio / Video Multimedia information Display

TBT : Turn By Turn Navigation Information Display

3.

Sound output

Various alarms and sound effects are issued through the external speakers connected to the dashboard.

If External AMP is applied, the directional alarm is outputted through the amp.

4.

User Setting Mode (USM)

Setting can be changed by using switchs (Menu, UP, Down and OK button). There are many items (for example, In/Out Seat Synchronization, In/Out Steering Wheel Synchronization, Auto Door Lock, Auto Door Lock Deactivate, Head Lamp Escort, Welcome Light, Welcome Sound, One Touch Turn Signal, Average Fuel Consumption Auto Reset, Brightness, and Content Setup) that can be set and customized. The signal flow during setting is as follows.

(1)

UMS settings are set, they are transmitted to BCM.

(2)

BCM transmits the settings via B-CAN to the relevant modules.

(3)

The module completes setting and transmits the modified setting to BCM.

(4)

BCM transmits the final settings via C-CAN to the cluster.

  

The cluster communicates directly with C-CAN units.

Hybrid Mian Features

1.

ECO and power guage

(1)

It displays the degree of economic driving by identifying the status of a driver's operation, depending on a vehicle's driving conditions (e.g., required power, system efficiency and charging).

(2)

It leads to economic driving by informing the driver of the optimal driving conditions depending on the vehicle's conditions.

(3)

It displays that ECO guide and power segment will operate during driving, and also indicates the state of regenerative braking when a charge zone is instructed while driving.

2.

SOC(State of Charge) guage

(1)

It displays the amount of charge of high-voltage battery.

(2)

It displays the charged amount of SOC received from BMS module on the digital gauge in the instrument cluster (as follows).

No.

3.

Energy Flow

(1)

It displays graphical energy flow of an HEV vehicle to inform the driver of the vehicle information.

(2)

It leads to economic driving by showing the energy flow diagram by means of intuitive images.

(3)

HCU module receives operation mode CAN signals to implement any relevant animation.

No.
