Abstract
Basic Function: Vehicle remote is used for vehicle lock/unlock/search/Hazard lights /approach light functions for customer convenience and vehicle security system.
Conventional approach:
- 1Use of separate RF (Radio Frequency) receiver -Additional Cost impact.
- 2High remote RF power - Reduced remote battery life and bigger remote size required
- 3High sensitivity RF receiver - High cost.
Low Cost approach:
It involves the followings:
- 1Integration of RF receiver inside the Body Control Module (BCM).
- 2Low Power Remote and Optimization of Remote PCB layout to get the maximum power.
- 3External wired antenna taken out from BCM and proper routine need be ensured to get the best performance.
- 4BCM mounting location to get the best remote range in all vehicle directions.
This paper relates to the methodology for low cost approach for the RF communication between remote transmitter and receiver with achieving the best remote performance at vehicle level condition.
