Vehicle Level Remote Range Improvement with Low Cost Approach 2012-01-0789

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:
  1. 1
    Use of separate RF (Radio Frequency) receiver -Additional Cost impact.
  2. 2
    High remote RF power - Reduced remote battery life and bigger remote size required
  3. 3
    High sensitivity RF receiver - High cost.
Low Cost approach:
It involves the followings:
  1. 1
    Integration of RF receiver inside the Body Control Module (BCM).
  2. 2
    Low Power Remote and Optimization of Remote PCB layout to get the maximum power.
  3. 3
    External wired antenna taken out from BCM and proper routine need be ensured to get the best performance.
  4. 4
    BCM 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.
