Vehicle control system

A vehicle control system comprising an operation amount generating node for computing an operation amount command value based on driver's demand signals and vehicle status signals from sensors, and actuator driving nodes each controlling an actuator in accordance with the operation amount command value from said operation amount generating node, thereby driving, steering and braking a vehicle,

• wherein each of said nodes has a failure detecting function and operates such that, when a failure is detected in itself with the failure detecting function, the relevant node does not make any action externally of the relevant node except for notifying that the relevant node is in a failed state, and when a failure occurs in any node, the other normal nodes than the failed node switch over control in accordance with a failure detecting notification from the failed node, thereby continuing normal operation as an entire system.

A vehicle control system comprising an operation amount generating node for generating an operation amount, a correction amount generating node for generating a correction amount, and an actuator driving node for driving an actuator,

• wherein said actuator driving node controls said actuator by using, as a control target value, a value obtained by adding the correction amount from said correction amount generating node to the operation amount from said operation amount generating node when said correction amount generating node is normal, and controls said actuator by using, as the control target value, the operation amount from said operation amount generating node when said correction amount generating node is abnormal.
