Abstract: A detection system for determining spark voltage of a spark plug in a capacitive discharge ignition system is disclosed. The detection system may have a sensor circuit configured to detect occurrence of a spark by measuring a voltage on a low side of a primary coil. The detection system may also have an electronic control unit connected to the sensor circuit. The electronic control unit may be configured to receive a signal from the sensor circuit indicating that the voltage exceeded a threshold. The electronic control unit may be further configured to determine a spark time based on the signal, and determine a spark voltage based on the spark time.

Abstract: A controller of a machine identifies that a battery of the machine is connected to an electrical power connector component. The controller then causes one or more charging components of the battery of the machine to be enabled, then cause one or more electrical components associated with the battery of the machine to be enabled, then causes one or more cooling components of the machine to be enabled, then causes one or more propulsion components of the machine to be disabled, then causes one or more accumulator components of a hydraulic system of the machine to bleed, and then causes one or more non-accumulator components of the hydraulic system of the machine to be enabled. In this way, the controller causes the battery of the machine to enter into a charging state.

Abstract: A method for steering alignment calibration of an articulated machine having front and rear frames pivotally connected by an articulation joint to steer the machine may include displaying a steering alignment calibration screen with a target steering angle between the frames and a calculated steering angle. The calculated steering angle may be determined based on a sensed steering angle and a calibration steering angle. The machine is steered until the displayed calculated steering angle is equal to the target steering angle. If an actual steering angle of the machine is not equal to the target steering angle, further steering is performed until the actual steering angle is equal to the target steering angle. The calibration steering angle may be recalculated and stored for future use when the actual steering angle is equal to the target steering angle but the calculated steering angle is not equal to the target steering angle.
