摘要： PROBLEM TO BE SOLVED: To stop transmission of tire pressure information during transportation of a vehicle without a trigger from the outside.
SOLUTION: An air pressure sensor 30 is provided at each wheel 20 of the vehicle to detect tire pressure. A transmitter 40 transmits the tire pressure detected by the air pressure sensor 30 to the vehicle body side. A transmission control part 42 determines that the vehicle is in the course of transportation and stops transmission from the transmitter 40 when the tire pressure is larger than a threshold value determined based on air pressure set during normal travel of the vehicle, and resumes transmission from the transmitter 40 when the tire pressure becomes the threshold value or less.

摘要： PROBLEM TO BE SOLVED: To automatically carry out initialization operation after air pressure adjustment in a tire air pressure monitoring device.
SOLUTION: An alarm determination part 118 determines abnormal air pressure when tire air pressure is reduced by a preliminarily defined ratio relative to set pressure. A data holding part 106 holds the tire air pressure detected by an air pressure sensor when the ignition of a vehicle is turned off and on about each wheel. An initialization determination part 108 calculates the variation amount of the tire air pressure of each wheel between ignition-off and ignition-on. When a variation amount is not smaller than a preliminarily defined threshold, the variation of the tire air pressure is determined to be due to intentional adjustment. An initialization part 112 resets the set value of the data holding part 106 when the tire air pressure is determined to be intentionally adjusted.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption by making a battery of a wheel-side device last long. SOLUTION: Air pressure of a tire is estimated based on a wheel speed by a second information processing section 62. Required information is transmitted to wheel-side devices 10-16 when the air pressure of the tire is suspected to be abnormal based on the estimated air pressure value. When the required information is received by the wheel-side devices 10-16, a pneumatic sensor 32 and a wheel information producing/transmitting section 40 are started to provide a power consumption state. The air pressure value of the tire is detected by the pneumatic sensor 32, and wheel information including the air pressure value is transmitted. In the wheel-side devices 10-16, the pneumatic sensor 32 and the wheel information producing/transmitting section 40 or the like are started if necessary, and power is consumed, so that power consumption speed of the battery is decreased and the battery can be made to endure.

摘要： PROBLEM TO BE SOLVED: To improve detection frequency and improve detection accuracy by sampling a predetermined frequency component from an oscillation frequency of a wheel speed and sampling a frequency component of a frequency range used for inflation pressure detection, and selecting a wheel revolution speed based on gain ratio such as deflection. SOLUTION: Pickup coils 14a through 14d fixed to rotation axles of tires 10a through 10d are connected to an ECU 16 The ECU 16 calculates a wheel speed from outputted alternating current signals, sampling oscillation frequency component thereof, performs frequency analysis (FFT), and calculates an overall gain. Next, calculation of gain in a frequency range used for inflation pressure detection is performed based on a result of FFT calculation, a gain ratio between the overall gain and the frequency range used for the inflation pressure detection is calculated, and it is determined whether the gain ratio is in an appropriate range. Even if the overall gain is small, as long as gain of the sampled frequency component is suitable for detection, this value is used for detection, increasing a detection frequency thereby.

摘要： PROBLEM TO BE SOLVED: To reduce electric energy required for transmitting information; and to acquire information for expressing further accurate air pressure in a wheel side device. SOLUTION: Air pressure information detected by an air pressure sensor 32 is transmitted to the car body side from the wheel side. The car body side extracts the information for expressing the air pressure by receiving the information transmitted from the wheel side, and acquires detecting information for expressing the detected air pressure. While the air pressure is estimated on the basis of a wheel speed, estimative information for expressing the estimated air pressure is acquired. The estimative information is always adopted as the air pressure information, and transmission prohibition indicating information is transmitted to the wheel side. While, when estimation accuracy is not more than a preset level when traveling on a bad road, the information is determined on the detecting information, and transmission permitting information is transmitted. Thus, the wheel side device reduces the electric energy required for transmitting the information, and can acquire the information for expressing the further accurate air pressure.

摘要： PROBLEM TO BE SOLVED: To prevent a degradation in linear regression accuracy by dispersion in a rotational state value, and eliminate dispersion in a pressure triggering a warning of a tire air pressure drop. SOLUTION: Ones in an effective range are selected from each of wheel speed deviation values D computed in a wheel speed deviation value computing part and front-to-rear wheel speed ratios β computed in a front-to-rear wheel speed ratio computing part, and then a regression line is derived from the selected wheel speed deviation values D and front-to-rear wheel speed ratios β. For example, a range of a given width centered on an initially computed slip deviation value A is used as the effective range, and the exclusion is taken to be outside the effective range.

摘要： PROBLEM TO BE SOLVED: To detect a tire air pressure drop accurately even under small dispersion in driving force. SOLUTION: If any dispersion is detected in wheel driving force, a wheel speed deviation value D is corrected according to a currently computed slip deviation value A, and if no dispersion is detected in wheel driving force., the wheel speed deviation value D is corrected according to a previously computed slip deviation value A*. Even under small deviation in driving force, regression accuracy is protected against degradation by a slight disturbance such as a slight turn, a rotational state value can be corrected accurately and a tire air pressure drop can be detected accurately.

摘要： PROBLEM TO BE SOLVED: To estimate tire inflation pressure without being influenced by load variation at the time of starting without requiring operation of an initialization switch by estimating the tire air pressure from deviation of a current dynamic load value against a dynamic load initial value provided immerdiately after starting. SOLUTION: In the case when a dynamic load initial value βo is not preserved, the dynamic load initial value βo is computed by a step 514, and after a dynamic load value βave is computed by a step S14, discrimination of lowering of tire air pressure by a dynamic load is carried out by a step S16. In the case when the dynamic load initial value βo is preserved, the dynamic load value βave is computed by a step S22, it is judged whether air pressure is normal or it is adjusted by steps S24-S28, and at the time when it is normal or it is adjusted, codes of βo and βo-βave are cleared. Thereafter, the dynamic load initial value βo is computed by a step S29, and judgement of lowering of tire air pressure by the dynamic load is carried out by a step 30. Consequently, it is possible to estimate tire inflation pressure without requiring operation of an initialization switch and without being influenced by load variation.
