Information Flow Prediction by Modeling Dynamic Probabilistic Social Network

A driving control apparatus for an engine of a vehicle comprises a first control unit 21 for calculating an engine control parameter, a second control unit 22 for calculating a throttle control amount, and first and second communication lines L1 and L2 for transmitting data between the first and the second control units. The second control unit includes an instrument for judging an abnormality of the first communication line L1. The first control unit includes an instrument for judging an abnormality of the second communication line L2, and second control unit monitor for monitoring an operation of the second control unit based on a first throttle opening degree signal T1 when an abnormality of each of the communication lines is judged. With the above arrangement, an abnormality of the second control unit can be judged at the side of the first control unit with a simple logic, and a reliable driving property can be secured at low costs.
