    Abstract: A misfire-detecting system detects a misfire occurring in an internal combustion engine in such a manner that a value of discharge current is detected when sparking voltage is generated in response to an ignition command signal, the detected value of discharge current is compared with a predetermined current value, and it is determined that a misfire has occurred when a time period over which the detected discharge current value after generation of the ignition command signal is above the predetermined current value is shorter than a predetermined time period.

    Abstract: In a keyless entry system, a CPU in an ECU and a CPU in a remote control key each have an associated memory for storing respective function formulas, which are specified by primary function formula data. With this structure, function formulas used in the remote control key and the ECU can be changed to respective new function formulas. This technique makes it difficult to predict the function formulas used in the remote control key and the ECU, thereby further reducing any regularity of rolling codes generated by the function formulas.

    Abstract: A vehicle system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals. The ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal.

    Abstract: A peak factor reduction unit that never allow peak factor reproduction even when interpolation is done in a succeeding stage. The unit detects a local maximum value of amplitude components from an input complex signal and supplies a complex signal that passes a band limiting baseband filter and an interpolation filter to a correction signal generation unit for generating a correction signal used for peak factor reduction and reduces a peak factor of the input complex signal with use of the correction signal generated from an interpolated complex signal.

    Abstract: An induction machine used as a power generator for an internal combustion engine, and which generates a predetermined power regardless of a rotation speed of a rotor of the induction machine and the engine. A power P to be generated is controlled so as to be equal to an upper limit value Pmax or less, a lower limit value or more or, equal to a target value Pc. The power generation control is achieved in the following manner. A speed N2 of the rotating magnetic field electrically generated with a three-phase winding of the rotor 1R is controlled in accordance with the mechanical rotation speed N1 of the rotor 1R in order that a relative speed N of the rotating magnetic field generated in the rotor with respect to a stator coil is kept at an upper limit speed Nmax or less, a lower limit speed Nmin or more, or a target relative speed Nc.
