1. A controller of a first vehicle, comprising:
a communication interface configured to periodically receive platoon messages from a second vehicle in a vehicle platoon of the first vehicle; and
a Cooperative Adaptive Cruise Control (CACC) controller configured to:
generate a safety driving model (SDM) for the first vehicle to perform control functions using first vehicle SDM parameters comprising at least a defined safe longitudinal distance between the first vehicle and the second vehicle;
determine the safe longitudinal distance using a response time that incorporates a frequency of the platoon messages periodically received from the second vehicle; and
cause the first vehicle to use the determined safe longitudinal distance as an inter-vehicle distance between the first vehicle and the second vehicle in the vehicle platoon.
