Motor vehicle control system and control unit therefor
First Claim
1. A control unit for a motor vehicle control system, said control unit comprising:
- means for connection to a sensor and for calculating a control parameter based upon data derived from an output of said sensor;
means for driving at least one actuator means in accordance with said calculated parameter;
means for communicating with other control units;
transmitting means for transmitting an interrogation signal to said other control units;
receiving means for receiving response signals from said other control units in response to said interrogation signals; and
modifying means connected with said receiving means for adaptively varying said control parameter in dependence upon the existence of the responses received by said receiving means.

Abstract
A motor vehicle control system and a control unit therefor is described, the control unit being arranged to calculate a control parameter based upon data derived from a sensor output and to drive at least one actuator in accordance with the calculated parameter. The control unit is adapted to communicate with a plurality of other control units and each of the control units comprises a transmitting means adapted to transmit interrogation signals to other control units and a receiving means adapted to receive response signals from the other control units in response to the interrogation signals. A microcomputer is provided adapted to vary the control parameter of each of the control units in dependence upon the existence of responses received by the receiving means of each control unit.
