Abstract: An autonomous dock system for a vehicle, comprises a control system with instructions comprising steps for receiving a request to implement an autonomous dock routine. A vehicle speed and clutch position are calculated. A clutch position controller is commanded to maintain the calculated clutch position. An actual torque amount is iteratively detected as transferred across the clutch. A vehicle speed-control mechanism is commanded to maintain the calculated vehicle speed, and the actual vehicle speed is iteratively detected. When comparing the commanded vehicle speed to the detected actual vehicle speed indicates that the detected actual vehicle speed is below a speed threshold, and when the actual torque amount transferred across the clutch exceeds a torque threshold, the control system commands an increase in vehicle speed.

Abstract: A storage system for managing an array of SSDs includes the array of SSDs and a host controller. Each of the SSDs is operable to store data. The host controller is configured to manage the array of SSDs as multiple logical volumes. Each of the logical volumes is associated with at least one stream ID. At least one of the SSDs and the host controller stores a system code configured to execute stream ID commands to access each of the logical volumes. Each of the logical volumes is dedicated to a memory region of each of the SSDs. Each of the logical volumes corresponding to the memory region of each of the SSDs are combined to form a logical volume group using the at least one stream ID. The host controller uses the stream ID commands to communicate with logical volumes of the logical volume group.

Abstract: A vehicle brake control system includes an inverter configured to convert direct current (DC) into an alternating current (AC) for a motor of a vehicle. The inverter includes switches configured to convert the DC to the AC, as well as a resistor and a bypass switch disposed in series with each other. A controller is communicatively coupled with the inverter switches and the bypass switch. The controller opens the bypass switch so that the DC is conducted through and converted into the AC for the motor during a motoring mode. The controller closes the bypass switch so that regenerated current from the motor is conducted through the resistor of the inverter for partial dissipation of the regenerated current during a dynamic braking mode.

Abstract: A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor.

Abstract: Methods for detecting a short fault of an alternator rectifier electronic component include sampling a field winding voltage or current signal of an alternator, during operation of the alternator, and determining a fault ripple period at which the alternator field winding signal exceeds a fault threshold. A short fault of an electronic component of a rectifier coupled to the alternator is detected in the event that the fault ripple period closely matches an alternator armature period. Alternatively or additionally, the sampled field winding signal is band pass filtered, and a short fault is detected in the event that an amplitude of the band pass filtered field winding signal exceeds a fault threshold. The methods can be implemented, for example, by an apparatus that includes a hysteresis frequency counter, a frequency comparator, and a countdown timer.

Abstract: The present invention discloses a back-propagating intersection collision avoidance (ICA) system for preventing two or more vehicles from colliding at an intersection. The ICA system can calculate predicted positions of the two or more vehicles in the near future, and both the current and future positions can be broadcast to surrounding vehicles using vehicle-to-vehicle communication. For each vehicle, a set of states, for example position, speed, acceleration, and the like, where a collision is imminent can be identified using state information for a local vehicle, a remote vehicle, and a known collision zone for the intersection. If the current states of the vehicles are determined to be in danger of entering the collision zone, the ICA system can control the vehicles to perform evasive driving maneuvers and/or alert the drivers.
