Abstract: PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of more easily and precisely detecting progress of sulfur poisoning of an NOx storage reduction catalyst. SOLUTION: If sulfur poisoning of the NOx storage reduction catalyst 4 adsorbing, reducing and converting NOx component in exhaust gas progresses, sulfur component in exhaust gas can not be sufficiently stored and is discharged to an exhaust gas downstream of the NOx storage reduction catalyst 4. The discharged sulfur component adheres on a detector of an oxygen concentration sensor 5 arranged in exhaust gas downstream of the NOx storage reduction catalyst 4 and changes sensor characteristics thereof. Progress of sulfur poisoning of the NOx storage reduction catalyst 4 is detected from the characteristic change of the oxygen concentration sensor 5. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To compensate variation of communication quality, in a communication system for a vehicle having a varied relative relationship between a transmitting means and a receiving means, caused by variation between the a relative relationship, and to suppress the occurrence of failure of communication. SOLUTION: The communication system for the vehicle is provided with a relative relationship detection means for detecting the relative relationship between the transmitting means and the receiving means; and a signal processing change means for changing the processing of a signal processed by a signal processing means. The signal processing change means changes the processing of the signal based on the detection result of the relative relationship detection means. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To acquire fitted tire information and non-fitted tire information separately, not requiring a special operation by a driver and causing no vehicular vibration. SOLUTION: A transmission change program S1 stored in each tire side transceiver of a fitted and non-fitted tires is used to detect whether or not a specified signal from a specified signal transmitter is received by the tire side transceiver. When the judgement is YES, the specified signal is judged as the non-fitted tire to set the nonfitted tire judgement information to '10'. When the specified signal is not received and the output value of a vibration sensor 33 is smaller than a set value, the tire has a high possibility of the non- fitted tire, and the non-fitted tire judgement information is set to '01'. Then, the transmission contents of the tire information based on the tire condition detected by various sensors are changed at S6, and is transmitted to the vehicle side receiver. The transmission change at S6 includes a tire information change, a tire information reduction and transmission interval change. The vehicular side receiver discriminates the fitted tire from the non-fitted tire based on the transmitted tire information to apply a different treatment. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To avoid deterioration of the communication state caused in a case where a wheel side communication device is rotated with a wheel to vary a relative position of a vehicle body side communication device and it, in technology for carrying out the communication with radio between the wheel side communication device and the vehicle side communication device in a vehicle.
SOLUTION: The communication system for the vehicle includes a transmitter 10 installed at a fixed position of the wheel, i.e., the transmitter for transmitting a signal to a receiver 12 at the vehicle body side; and a position sensor 22 for detecting a rotation position of the wheel. The transmitter 10 is constituted such that it transmits the signal to the receiver 12 at the timing corresponding to the rotation position of the wheel based on the rotation position detected by the position sensor 22.

Abstract: PROBLEM TO BE SOLVED: To automatically register information corresponding to wheel identification information in vehicle-body-side device, in a wheel state acquisition device in which a wheel state is acquired by communication between a wheel-side device and the vehicle-body-side device. SOLUTION: Antennas 75, 76 for outputting trigger signals are mounted on a wheel mounting state inspection device. In a case where the wheel mounting state inspection device 14 faces a wheel, when the wheel is rotated, the wheel-side device 100 faces either of the antennas 75, 76, so that the identification information are transmitted from the wheel-side device by the trigger signals transmitted from the antennas 75, 76. The transmitted identification information are received and registered by the vehicle-body-side device 102. Thus, a worker can eliminate the need for transportation of a trigger device for each wheel and can automatically register the identification information. COPYRIGHT: (C)2004,JPO

Abstract: PURPOSE: To prevent a sudden change in auxiliary steering effort at before and after fail. CONSTITUTION: Under a normal state, a voltage applied to auxiliary steering effort generating means C1 is decided by means of voltage deciding means C4 based on desired auxiliary steering effort decided by means of auxiliary steering effort deciding means C2 and the resistnce value related amount of the auxiliary steering power generating means C1 detected by means of resistance value related amount detecting means C3. A voltage decided by means of voltage application means C5 is applied. Meanwhile, when impossibility determining means C6 determines that the detection of a resistnce valve related amount by means of the resistance value related amount detecting means C3 is in an impossible state, an application voltage from the voltage applications means C5 is decided by means of current value sudden change suppressing means C7 so that a current amount from the auxiliary steering effort generating means C1 may not suddenly be changed before and after (in timewise) determining detection impossibility by means of the impossibility determining means C6. The voltage is applied to the auxiliary steering effort generating means C1.

Abstract: PURPOSE:To prevent the fluctuation of the driving torque when a throttle valve is opened by opening the throttle valve from the idling position while a lock-up clutch is temporarily set to the non-lock-up state during the automatic drive control. CONSTITUTION:An automatic drive control device normally outputs the lock-up signal to a lock-up clutch to set it to the lock-up state, if a constant-speed running command is issued in place of a deceleration running command, the output of the lock-up signal is interrupted, and a signal for opening a throttle valve from the idling position is outputted to an actuator controlling the throttle valve after a fixed period T0 elapses. When the throttle valve is actually opened from the idling position, the output of the lock-up signal is restarted.
