    摘要: A vehicle security system includes a reception device that is mounted on a vehicle, and a transmission device that remotely operates the vehicle. The transmission device includes an encryption section that encrypts identification information that identifies the transmission device with a first encryption key, and a transmission section that transmits to the reception device instruction information that includes the identification information encrypted and gives an operation instruction to the reception device. The reception device includes a FeRAM that stores a second encryption key to pair with the first encryption key, wherein the second encryption key is erased from the FeRAM when the second encryption key is read out from the FeRAM, a reception section that receives the instruction information transmitted from the transmission device, a decoding section that decodes the identification information received, which is encrypted with the first encryption key and included in the received instruction information, with the second encryption key that is supposed to be stored in the FeRAM, and a judgment section that judges based on the decoded identification information as to whether the transmission device matches with the reception device.

    摘要: A control system for an internal combustion engine which performs an engine output control so that an output of the engine coincides with a demand output by changing at least one of the intake air flow rate and an ignition timing of the engine. An output reduction control in which the engine output is reduced by changing at least one of the intake air flow rate and the ignition timing, is performed when the demand output decreases. A retard limit of the ignition timing is calculated according to an operating condition of the engine. A retard limit output, which is an output of the engine corresponding to a state where the ignition timing is retarded to the retard limit and the intake air flow rate is maintained at a value immediately before the demand output decreases, is calculated. A retard limit intake air flow rate is calculated when the demand output is less than the retard limit output. The retard limit intake air flow rate is an intake air flow rate at which the engine output is equal to the demand output under the condition where the ignition timing is retarded to the retard limit. The engine output is made to coincide with the demand output by retarding the ignition timing, when the demand output is equal to or greater than the retard limit output. When the demand output is less than the retard limit output, the ignition timing is retarded to the retard limit and the intake air flow rate is controlled so as to coincide with the retard limit intake air flow rate.
