Abstract:
1. A vehicle motion control system for enabling a plurality of vehicle behavior control units to operate in a mutually coordinated manner, comprising: a first vehicle behavior control unit including a first central processing unit (CPU) programmed to generate a first coordination control signal; a second vehicle behavior control unit including a second CPU different from the first CPU and programmed to operate in a coordinated manner with respect to the first vehicle behavior control unit according to the first coordination control signal; a third vehicle behavior control unit including a third CPU different from the first and second CPUs and programmed to operate in a coordinated manner with respect to the first vehicle behavior control unit according to the first coordination control signal; a coordination control signal storage device that stores the first coordination control signal; and a failure detection unit for detecting a failure of the first vehicle behavior control unit; wherein the second vehicle behavior control unit is incorporated with the coordination control signal storage device, and upon detection of the failure of the first vehicle behavior control unit by the failure detection unit, transmits to the third vehicle behavior control unit the first coordination control signal stored in the coordination control signal storage device immediately before the detection of the failure of the first vehicle behavior control unit; and wherein upon detection of the failure of the first vehicle behavior control unit, the second vehicle control unit is configured to maintain a coordinated operation thereof according to the first coordination control signal stored in the coordination control signal storage device immediately before the detection of the failure, and the third vehicle behavior control unit maintains a coordinated operation thereof according to the first coordination control signal transmitted by the second vehicle behavior control unit.
