Abstract

An aware vehicle network system and method for one or more vehicles each having adaptive active suspensions includes at least one vehicle having a vehicle position detector for determining a vehicle position and a road condition detector for determining road condition information for any given position determined by the vehicle position detector. A transmitter sends the road condition information and the vehicle position over a vehicle communication network. A central network device receives the road condition information and the vehicle position and calculates ideal active suspension parameters based thereon. The network device sends ideal active suspension parameters over the vehicle communication network to at least another vehicle having an adaptive active suspension. The adaptive active suspension is adjusted based on the ideal suspension parameters received from the network device.
