Abstract

The invention relates to a vehicle integrated-control apparatus and method that controls at least a drive control system, a brake control system, and a dynamic behavior control system in an integrated manner. A temporary control target (F0) is set in response to the operation of an input member operated by a driver: a signal indicating the temporary control target (F0) is transmitted to the dynamic behavior control system: the temporary control target (F0) is partitioned into a control target allocated to the drive control system and a control target allocated to the brake control system based on a predetermined allocation rate: a signal indicating a post-partition control target (F1) is output to the appropriate system for achieving the post-partition control target (F1): an instruction from the dynamic behavior control system to correct the temporary control target (F0) is received: the temporary control target (F0) is corrected in accordance with the instruction from the dynamic behavior control system: and a signal indicating a corrected control target (F3) is output to the appropriate system for achieving the corrected control target (F3).

a dynamic behavior control system which stabilizes a dynamic behavior of a vehicle, and that controls at least the drive control system, the brake control system, and the dynamic behavior control system in an integrated manner, comprising;

a temporary-setting device that sets a temporary target driving force based on an operation amount of an input member of the drive control system operated by a driver;

a transmitting device that transmits a signal indicating the temporary target driving force to the dynamic behavior control system;

a first output device that partitions the temporary target driving force into a post-partition target driving force allocated to the drive control system and a control target allocated to the brake control system based on a predetermined allocation rate, and outputting a signal indicating the post-partition target driving force, derived after partition, to at least one of second output devices;

16. The vehicle integrated-control apparatus according to claim 15, wherein

the dynamic behavior control system outputs a signal to the correction device instructing the correction device to correct the temporary target driving force by replacing the temporary target driving force with an absolute amount rather than a relative amount by which the temporary target driving force should be changed.
