Abstract: A pressure sensing system includes a pressure transducer, a pressure manifold, and a heater assembly. The pressure transducer is configured to measure pressures at one or more locations of a vehicle engine. The pressure manifold is configured to cover a face of the pressure transducer and provide an interface for transferring air or gas generated at the one or more locations of the vehicle engine. The heater assembly is configured to heat one or more portions of the pressure transducer and one or more portions of the pressure manifold and maintain a temperature of each of the pressure transducer and the pressure manifold above a predetermined temperature level.

Abstract: Method and system for assigning addresses to end point devices in a network includes placing a mobile device in close proximity to a first end point device and establishing a wireless connection, transmitting an auto-addressing command from the mobile device to the end point device in response to the connection being established and disconnecting the connection in response to the end point device being configured with the network address. As the mobile device is moved through the system, when the wireless signal strength between the mobile device and a respective the end point device exceeds a threshold, both devices recognize that they are in close proximity and the mobile device transfers the address configuration information to the end point device. By moving the mobile device through the system the steps are automatically repeated until the mobile device assigns address and location information to each end point device on the network. The initialization process also involves assigning personality information to end devices that define particular behaviors that the end devices shall assume in the configured system.

Abstract: In one aspect, a system for torsional damping of electric traction drives comprises dual Kalman filters to correct for oscillations based on measured traction motor speed and commanded traction motor torque. A first Kalman filter can perform a state space estimate of the shaft torque providing negative feedback to the final torque command in order to eliminate resonant components from the commanded torque and quickly damp external disturbances. A second Kalman filter provides a state space estimation of the load torque or, equivalently, load acceleration. This second Kalman filter can ignore commanded torque and can provide a damping feedback when the wheel speed deviates from the vehicle speed.

Abstract: A plurality of control channels each include a power supply, an interface that receives a manipulation signal, an arithmetic processing portion that calculates and generates an operation command signal for actuators based on the manipulation signal, and a signal determination unit that determines a control signal for finally controlling the operation of the actuators and outputs the control signal. The arithmetic processing portions respectively provided in the plurality of control channels have designs different from one another. Each of the signal determination units determines the control signal by receiving a first operation command signal generated by the arithmetic processing portion of the control channel in which that signal determination unit is provided, and a second operation command signal generated in the arithmetic processing portion of another of the control channels, and comparing the first operation command signal and the second operation command signal, and outputs the control signal.

Abstract: A multi-wire choke filter is implemented in an inverter module of a modular power control system for a vehicle. Such an inverter module includes gate driver circuits to control switching power transistors used to power loads in a vehicle. The switching power transistors and gate drivers are configurable to support both a three-phase and a single phase current drive driver circuit topology in which switching power transistors are connected in parallel to share driving currents and dynamic switching losses. In any configured topology, the multi-wire choke is connected in series between gate driver circuit components and switching power transistors to mitigate any EMI threat to the gate driver circuitry by presenting an impedance to reduce circuit susceptibility to any differential and common mode noise currents that can flow through the gate driver circuit that can overwhelm gate driver circuitry and negatively effect power transistor switching performance at any time.

Abstract: A high voltage measurement port and a circuit contact wire assembly for vehicle high-voltage power decommissioning. The high voltage measurement port includes four externally accessible pins for obtaining an electrical characteristic measurement of a connected circuit. For redundancy, the assembly includes a resistor between a first measurement port pin and a first positive DC busbar at a first location, a resistor between a second pin and the first DC busbar at a second location different from the first location, a resistor between a third pin and a second negative DC busbar at a first location, and a resistor between a fourth pin and the second DC busbar at a second location different from the first location. Via the high voltage measurement port, a multi-meter can verify each resistance connection between the positive pins and then again between negative pins before a differential voltage measurement is made between positive and negative.
