摘要： Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time. Other control systems modify a coolant flow rate based on differences between designated and ambient conditions.

摘要： Embodiments of the subject matter disclosed herein relate to controlling engine operating points and power for full throttle command in an off-highway vehicle, such as a diesel electric haul truck, to increase fuel efficiency. In one example, a system includes an engine and a controller. The controller is configured to determine a target engine horsepower and associated target engine speed, command the engine to operate at a first engine speed above the target engine speed, adjust a load placed on the engine to reach the target engine speed, and command the engine to operate at a second engine speed to reach the target engine horsepower.

摘要： A power conversion system includes a bus bar, a switch coupled to the bus bar and configured to receive a DC input voltage from a voltage source through the bus bar, and a parallel fuse system. The parallel fuse system may be disposed on the bus bar in series with the voltage source and the switch. The parallel fuse system includes two or more parallel fuses, and may be configured for an inductance imbalance between the fuses, such that there is an asymmetric flow of currents through the fuses when the power conversion system is in operation. For the inductance imbalance, for example, the fuses may be positioned asymmetrically with regard to a shortest conductive path from the voltage source to the switch.

摘要： A system and method for auxiliary clutch failure detection determines a difference between a first output power of a powered system when a clutch system is controlled to engage and drive a load at a first output of the load and a second output power of the powered system when the clutch system is controlled to drive the load at a larger, second output. A control signal indicative of clutch failure is generated responsive to the difference being less than a designated threshold. The control signal may be used to implement one or more remedial actions.
