Abstract: A system and method for determining the presence of a hidden hazard may include identification of an operational scene for a host vehicle, and identification of an operational situation for the host vehicle. Information from a plurality of proximity sensors is collected and classified. A plurality of hidden hazard presence probabilities corresponding to the information from each of the plurality of proximity sensors, the operational scene, the operational situation, and at least one of a comparative process and a dynamic neural network process are estimated. A fusion process may be performed upon the plurality of hidden hazard presence probabilities to determine the presence of a hidden hazard.

Abstract: A system and method for predicting a collision between a host vehicle and a target vehicle operating on a multi-lane roadway may include determining the host and target vehicles are converging from respective first and second lanes to a third lane intermediate the first and second lanes. A predetermined set of conditions is evaluated including relationships among the host and target vehicle separations and speeds, and a collision predicted based upon the evaluation.

Abstract: A method of monitoring a propulsion system of a vehicle includes determining a health indicator from a diagnostic signal based on electrical outputs from a resolver connected to an electric motor of the propulsion system, the diagnostic signal related to a resolver offset and/or a resolver wobble, calculating a reference value based on values of the health indicator determined during a first time period, and monitoring the health indicator over a second time period, where the monitoring includes continuously or periodically calculating a trend value of the health indicator over a plurality of cycles. The method also includes comparing each trend value to the reference value and estimating a difference between the trend value and the reference value for each cycle, predicting whether a fault will occur based on the difference, and based on the predicting indicating that a fault will occur, outputting a fault indication.

Abstract: Apparatus and techniques for analyzing a capacitance value in an electric motor inverter are disclosed. A processor is coupled to a DC-AC inverter, which includes a capacitor across its terminals and is powered by a battery. The processor performs resistor switching to enable singular, periodic measurement of the capacitance. The measured value is compared with a nominal or beginning of life (BOL) value. An alert may be sent if the capacitance has degraded beyond a threshold. In other aspects, the DC torque ripple envelop is used to measure capacitance. The outcome is compared with the other tests to assess consistency. An inconsistent outcome may identify potential resistor degradation.

Abstract: A control system for an electric motor includes a power input calculating module configured to calculate power input to the electric motor. A power output calculating module is configured to calculate power output by the electric motor. A power loss calculating module is configured to calculate power loss in the electric motor based on the power input and the power output. A fault module is configured to compare the power loss in the electric motor to one or more predetermined power loss thresholds and to selectively alter operation of the electric motor based on the comparison.

Abstract: Systems and methods for vehicle-target localization, identification and indication. The system includes a vehicle module operating onboard a vehicle and configured to receive a request for a tether and send the tether responsive thereto, and a target module operating on a target external to the vehicle. The target module can generate target profile data (TPD) comprising location information for the target, such as, a first component that is a function of a detected first WiFi signal having a first signal strength. The request for the tether including the TPD is transmitted to the vehicle module; a tether of secured communications is established between the vehicle module and target module. Real-time TPD is exchanged during the tether and the vehicle module performs the V-T localization as a function of the RT TPD, and commands the vehicle based on V-T localization data.

Abstract: An electric drive system of a vehicle comprises a motor, a position sensor, an inverter, sensors to sense current and voltage supplied to the motor, and a controller to control the motor by controlling the inverter based on data from the position sensor and the sensors and a torque command. The controller estimates a motor torque using a motor model, calculates the motor torque, and generates a first state of health for the electric drive system based on a difference between the estimated and calculated motor torques. The controller generates, in response to the first state of health being less than or equal to a first threshold, a second state of health for at least one of the position sensor, the sensors, and the motor, and determines whether one of the position sensor, the sensors, and the motor is faulty based on the first and second states of health.

Abstract: A process for local traffic approximation through analysis of cloud data is provided. The process includes, within a computerized traffic flow estimation controller of a host vehicle, operating programming to monitor a planned navigational route of the host vehicle, identify along the planned navigational route a road section including cross-traffic, monitor cloud data related to a mobile cellular device, analyze the cloud data to identify traffic posing a hazardous condition to the host vehicle within the road section, and generate a vehicle alert to a driver of the host vehicle based upon the identified traffic.

Abstract: Methods and systems to implement sensor fusion to determine collision potential for a vehicle include identifying a specific intersection that the vehicle is approaching, and identifying collision potential scenarios associated with one or more paths through the specific intersection. Each collision potential scenario defines a risk of a collision between the vehicle and an object in a specified area. A weight with which one or more information sources of the vehicle are considered is adjusted for each collision potential scenario such that a highest weight is given to one or more of the one or more information sources that provide most relevant and reliable information about the specified area. Sensor fusion is implemented based on the adjusting the weight of the one or more information sources and performing detection based on the sensor fusion, and an alert is provided or actions are implemented according to the detection.
