Abstract

Disclosed herein is an integrated vehicle control system, which eliminates the possibility of interfering with motion control devices and is capable of accurately controlling the targeted behavior of a vehicle.

Claims

1. An integrated vehicle control system, comprising:

a sensor unit configured to obtain information about a vehicle and peripheral information;

a plurality of actuators configured to control behavior of the vehicle;

an integrated control unit configured to calculate control target values for one or more of the actuators, based on the vehicle information and the peripheral information received from the sensor unit;

a coordinator configured to (i) perform feedforward decoupling control so that possible interference components that may occur on the actuators due to the control target values offset each other wherein the coordinator includes one or more feedforward parameters required to offset mutual interference components between the actuators that may interfere with each other, the one or more feedforward parameters corresponding to control parameters of the respective actuators obtained based on a full vehicle model and (ii) output to the driving unit a decoupling control value to which a control target is added, wherein the control target is a control component corresponding to a control input value expected for a target actuator, and from which interference unexpected components are subtracted in advance from the decoupling control value, wherein the interference unexpected components are attributable to control input values of actuators other than the target actuator; and

a driving unit configured to convert values output from the coordinator into drive values for the respective actuators.

2. The integrated vehicle control system according to claim 1, wherein the integrated control unit is configured based on the full vehicle model.

3. The integrated vehicle control system according to claim 2, wherein the integrated control unit performs feedback control to detect results of control through the actuators.

4. The integrated vehicle control system according to claim 1, wherein the driving unit comprises driving elements included in installation regions of the respective actuators, the driving elements being operated autonomously in parallel with each other.

5. The integrated vehicle control system according to claim 4, wherein the plurality of actuators comprises an actuator used for an Advanced Safety Vehicle (ASV).

6. A motor vehicle comprising the integrated vehicle control system of claim 1.
