A controller for an exhaust brake device is provided whereby the braking force of the exhaust brake device can be ensured sufficiently, even at low vehicle speeds. A controller for an exhaust brake device (73) used in combination with a power transmission device comprising a fluid coupling (2) connected to the output shaft (1a) of an engine (E), a clutch (3) interposed between the fluid coupling (2) and a gearbox (T/M), and a lock-up clutch (7) for mechanically disengaging and engaging the fluid coupling (2), is provided, and this controller is provided with an electronic control unit (22) for controlling the engagement and disengagement of the lock-up clutch (7) and the operation of the exhaust brake device (73). The electronic control unit (22) permits operation of the exhaust brake device (73) in the range of engagement of the lock-up clutch (7).
