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.

User Setting Mode (USM)

Setting can be changed by using the haptic switch menu, and CW, CCW, OK buttons (or the UP, Down, Left, Right and OK button of the generic switch). There are total of 24 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, Triple Turn Signal, Average Fuel Consumption Auto Reset, HUD Height Adjustment, Brightness, and Content Setup) that can be set and customized. The signal flow during setting is as follows.

(1)

USM settings are set, they are transmitted to IBU.

(2)

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

(3)

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

(4)

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

  

The cluster communicates directly with C-CAN units.
