摘要： A control system and method for controlling pump includes a pump control module communicating a drive signal to the high pressure pump and a high pressure pump in communication with the pump control module operating in response to the drive signal. A current sampling module samples a pump current signal to form a sample prior to an end of the drive signal. A current comparison module compares the sample to a threshold that may be a function of pump solenoid resistance, pump solenoid temperature, and/or system voltage, and a fault indication module generates a fault signal in response to comparing.

摘要： In a method for detecting a signal in a multi-input multi-output wireless communication system that receives signals transmitted through a plurality of transmission antennas by using a plurality of reception antennas, a detection order for detecting the transmission signals received through the reception antennas is determined on the basis of a cofactor determinant of components constituting a channel matrix representing characteristics of channels between the transmission antennas and the reception antennas. In addition, the transmission signal is detected from the signals received through the reception antennas in accordance with the determined detection order.

摘要： A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual.
