ABSTRACT:
A control system and method is disclosed for an electromagnetic clutch brake, including an electromagnetic clutch brake actuator coil surrounding a power input shaft for a multiple-ratio transmission in a vehicle powertrain. A protective circuit of the control system normally monitors data inputs that indicate conditions that are not favorable for clutch brake actuation. The protective circuit prevents actuation of the clutch brake under such conditions. The protective circuit may monitor a plurality of signals including a vehicle speed signal which prevents engagement of the clutch brake unless the vehicle speed is below a predetermined level. The system may further include a transmission neutral switch that permits bypassing monitoring the vehicle speed signal when the transmission neutral switch is actuated.
