Patent attributes
A fire fighting vehicle includes a chassis, a front axle, a rear axle, an engine, an energy storage device, an electromechanical transmission, a vehicle subsystem, and a power divider. The electromechanical transmission is (i) coupled to at least one of the front axle or the rear axle and (ii) electrically coupled to the energy storage device. The power divider is positioned between the engine, the vehicle subsystem, and the electromechanical transmission. The power divider includes a first interface coupled to the engine, a second interface coupled to the vehicle subsystem, and a third interface coupled to the electromechanical transmission. The power divider is configured to facilitate (i) selectively coupling the engine to the vehicle subsystem and (ii) selectively coupling the engine to the electromechanical transmission.
