Patent Images
1. A method for producing a response to road conditions ahead of a vehicle, comprising the steps of:
- identifying a first vehicle ahead of a second vehicle traveling along the same path;
electronically sensing non-vehicular driving condition information local to said first vehicle, said step of electronically sensing non-vehicular driving condition information being performed automatically by electronic apparatus within said first vehicle;
transmitting said non-vehicular driving condition information from said first vehicle to said second vehicle;
producing a response to said non-vehicular driving condition information in said second vehicle, said step of producing a response to said driving condition information being performed automatically by electronic apparatus within said second vehicle.

Abstract
A method for producing a response to driving conditions ahead of a land vehicle such as an automobile includes a second vehicle using information received from a first vehicle traveling ahead of it to adjust vehicle mechanisms such as the suspension to cancel adverse effects of road anomalies sensed by the first vehicle.
