Abstract: Systems and methods for bypassing a compromised engine cylinder via cylinder deactivation are described according to various embodiments herein. A system includes an engine coupled to a controller. The controller includes at least one processor and at least one memory coupled to the at least one processor. The at least one memory stores instructions that, when executed by the at least one processor, cause the controller to: determine that one or more cylinders of a plurality of cylinders of the engine is compromised based on data regarding operation of the engine; and cause the engine to operate in the modified engine operating mode whereby operation of the one or more cylinders that are compromised is modified.

Abstract: A system includes a controller having at least one processing circuit including at least one memory coupled to at least one processor. The controller is configured to: receive data regarding operation of an engine indicating that one or more cylinders of a plurality of cylinders of the engine is compromised; cause the engine to operate in a modified engine operating mode whereby operation of the one or more cylinders that is compromised is modified; cause the engine to operate in a non-modified engine operating mode whereby operation of the one or more cylinders that is compromised is not modified responsive to receiving information regarding a predetermined condition despite the data regarding operation of the engine indicating that the one or more cylinders of the plurality of cylinders of the engine is compromised.

Abstract: A method of route planning for an electric vehicle includes obtaining waypoint data that indicates waypoint locations for the electric vehicle. The method also includes generating a map and a plurality of route segments to connect each of the waypoint locations on the map. Further, the method includes calculating an optimal route for the electric vehicle to visit each of the waypoint locations by evaluating the plurality of route segments. In response to detecting changes occurring in conditions associated with each of the plurality of route segments, the method includes recalculating the optimal route for the electric vehicle.

Abstract: A prime mover system includes a first prime mover, a first drive shaft, a differential, a power take-off (PTO) drive shaft, a second drive shaft, a transmission, a first accessory, and an output shaft. The first drive shaft is operatively coupled to the first prime mover. The differential is coupled to the first drive shaft. The PTO drive shaft is coupled to the differential. The second drive shaft is coupled to the differential. The transmission is coupled to the second drive shaft. The first accessory is operatively coupled to the PTO drive shaft. The output shaft is coupled to the transmission. The transmission is configured to transfer rotation of the second drive shaft to the output shaft. Rotation of the PTO drive shaft is independent of rotation of the output shaft.

Abstract: A system is provided for performing a predicted cooling operation for an electric vehicle (102) using a processor (122), and includes a vehicle monitoring unit (128) configured to monitor one or more vehicle characteristics related to the electric vehicle (102). The one or more vehicle characteristics include look-ahead demand information of one or more components of the electric vehicle (102). A cooling controller (126) is configured to communicate with the vehicle monitoring unit (128) and determine the look-ahead demand information based on at least one of: navigational information, thermal information, and environment information associated with the electric vehicle (102). The cooling controller (126) is configured to generate a cooling command based on the look-ahead demand information and perform the predicted cooling operation based on the cooling command by over-cooling the one or more components of the electric vehicle (102).
