摘要： A switch arrangement for providing alternative distribution paths in a system for distributing electrical power in a vehicle including electrical power supplies and electrical loads. The switch arrangement includes a first switch adapted to be connected to a first electrical element, a second switch adapted to be connected to the first electrical element and a second electrical element, and a third switch adapted to be connected to the electrical element and a third electrical element. Each of the first, second, and third switches is independently controllable, and selective operation of each of the first, second, and third switches to its open or closed state interconnects at least two of the first, second, and third electrical elements to establish one of multiple alternative distribution paths to connect one of the power supplies and one of the loads or to connect two of the power supplies.

摘要： An apparatus for determining integrity of an electronic device in a vehicle is provided. The apparatus comprises a controller operably coupled to a high voltage measuring circuit and to an analog-to-digital converter (ADC). The high voltage measuring circuit receives a high voltage signal and includes at least one stressed resistor for reducing the high voltage signal into a suitable voltage signal. The ADC performs a measurement with the suitable voltage that is indicative of the high voltage signal in a normal operation mode. The controller is configured to apply a calibrated voltage to the at least one stressed resistor in a calibration mode. The controller is further configured to calculate a resistance value of the at least one stressed resistor based on applying the calibrated voltage to the at least one stressed resistor to determine if the at least one stressed resistor is in a stressed state.

摘要： A sensor for monitoring battery current includes a shunt and a current source. The shunt has a resistance with an actual value. The current source is configured to provide a known value of current through the shunt. A controller is configured to generate a measured value of the current through the shunt as a function of a measured value of voltage drop across the shunt caused by the current through the shunt and an assumed value of the resistance of the shunt. The controller is further configured to detect the assumed value of the resistance of the shunt as being different than the actual value of the resistance of the shunt when the known and measured values of the current differ.

摘要： An electronic control unit (ECU) for vehicles is described, including memory to store encrypted data and unencrypted data; a main control unit operatively connected to memory to access unencrypted data; and a hardware encryption-decryption device operatively connected to memory to access encrypted/decrypted data for decryption using a hardware algorithm and for encryption using a hardware algorithm. Data in the memory is decrypted by the hardware encryption-decryption device using the hardware algorithm and stored in memory for use by the main control unit. Data in memory is encrypted by the hardware encryption-decryption device using the hardware algorithm for storage in memory. The main control unit and the hardware encryption-decryption device are separate integrate circuits on a same substrate or and are connected by a bus and can process data in parallel. An external bus can communicate encrypted information with the ECU to allow encrypt/decrypt at run time (on-the-fly) and wire-speed.

摘要： Operation for performing diagnostics, such as vehicle diagnostics including short circuit and low impedance diagnostics during a high-voltage (HV) battery pre-charging a power-net of the vehicle and including insulation resistance monitoring diagnostics for measuring an insulation resistance between the power-net and another power-net, with reduced processing time includes measuring a physical parameter (voltage or current signal) as the parameter is being generated by a device-under-test to which the diagnostic process pertains. The diagnostic process requires a stable value of the parameter. The parameter variates while being generated during a beginning time and is stable while being generated during an ending time. While the parameter is being generated during the beginning time, a stable value of the parameter which the parameter will have during the ending time is predicted. The stable value of the parameter is predicted based on variation of measured values of the parameter during the beginning time.
