Brake system

1. A brake system comprising: (a) a pair of electric brake devices respectively provided for a right wheel and a left wheel of a vehicle; (b) a pair of individual controllers respectively associated with the electric brake devices to respectively control the electric brake devices; (c) a central controller communicable with the individual controllers to control the electric brake devices in a centralized manner; and (d) an on-vehicle network to which the central controller and the individual controllers are connected,

wherein the central controller is configured to transmit, via the on-vehicle network, control commands to the respective individual controllers as signals containing destination information of the respective individual controllers,

wherein each of the individual controllers is configured to control an associated one of the electric brake devices according to the control command based on the signal containing the destination information of its own, and

wherein the brake system further comprises a position-change determining device configured to determine, based on a turning behavior of the vehicle, that positions of the pair of individual controllers are mutually changed with respect to the association with the pair of electric brake devices.

2. The brake system according to claim 1 ,

wherein each of the electric brake devices includes: a rotation body configured to rotate together with a corresponding one of the right wheel and the left wheel; and a caliper holding a friction member and including an actuator configured to push the friction member onto the rotation body, and

wherein each of the individual controllers is attached to the caliper of a corresponding one of the electric brake devices.

3. The brake system according to claim 1 ,

wherein the pair of electric brake devices are provided for a right wheel and a left wheel which are one of front wheels and rear wheels of the vehicle, and another brake device is provided for a right wheel and a left wheel which are the other of the front wheels and the rear wheels of the vehicle,

wherein the central controller is configured to execute a diagonal braking-force generating control in which the central controller causes one of the electric brake devices corresponding to one of the right wheel and the left wheel to generate a braking force and causes said another brake device to generate a braking force for one of the right wheel and the left wheel which is positioned diagonally with respect to the one of the right wheel and the left wheel for which the one of the electric brake devices generates the braking force, and

wherein the position-change determining device is configured to determine that the positions of the individual controllers are mutually changed, based on the turning behavior of the vehicle during execution of the diagonal braking-force generating control.

4. The brake system according to claim 1 ,

wherein the vehicle includes a yaw rate sensor, and

wherein the position-change determining device is configured to determine that the positions of the individual controllers are mutually changed based on the turning behavior of the vehicle estimated based on a yaw rate detected by the yaw rate sensor.

5. The brake system according to claim 1 , wherein the position-change determining device is configured to determine that the positions of the individual controller are mutually changed based on the turning behavior of the vehicle estimated in consideration of an operation amount of a steering operation member of the vehicle.

6. The brake system according to claim 1 ,

wherein each of the individual controllers stores identification information of its own that includes information indicating with which one of the electric brake devices the individual controller is ought to be associated, and

wherein the central controller is configured to set the destination information for each of the individual controllers based on the identification information of its own.
