1. SYSTEM OVERVIEW
This short system description gives an overview about the functionality of the
Keyless Vehicle (KV) system and from the Keyless Vehicle Module (KVM).
The vehicle and the Passive Key (PK) will communicate via challenge / response.
By any request the KVM sends a challenge via the respective LF-antennas with
125 KHz to the Passive Key. The PK’s within the detection range answer via
Radio Frequency (RF) transmission. The external RF-Receiver sends the data
from the received signal via serial link to the KVM. The system will provide a
specific PK detection function for inside and outside detection range.
Different failure modes and diagnostic data will be displayed to the driver from
KVM via the Mid Speed CAN-Bus to display at the cluster.
For back up reasons, the Passive Key will provide a metal key blade for locking /
unlocking the vehicle and for starting the engine after key is inserted in ignition
switch (ignition key cylinder) and turned to crank position.

3. Duty Cycle
20 actuations of access control system within 24 hours with a typical transmission
time of 0.08 seconds. 0.07 seconds / hour.
Transmission time TON 0.07 seconds / hours
Off time T OFF 3599.93 seconds / hours
Duty Cycle: TON / T (ON+OFF) x 100% = 0,07 / 3.600 x 100 % = 0.02 %
