摘要： In a tire air pressure estimation based upon vibration components extracted from a vehicle wheel speed signal, when the vehicle is a driven vehicle wheel, the precision of estimation is improved by canceling the components of vibration due to the resonance of the drive system from the vibration components based upon which the estimation calculation is made. The vibration components due to the resonance of the drive system can be canceled by canceling those vibration components extracted from the vehicle wheel speed signal which are the same in the phase between left and right driven vehicle wheels. When the tire air pressure of one of a pair of left and right driven vehicle wheels is lower than that of the other, the lower tire air pressure is more correctly estimated. Therefore, the higher tire air pressure may be estimated according to the lower tire air pressure against the drive system resonance.

摘要： Pickup coils (3a-3d) which generate vehicle wheel speed signals (V) which include vibration frequency components of tires (1a-1d) during vehicle cruising are provided. An electronic control unit (4) extracts resonance frequencies (f 0B , f k ) of tires (1a-1d) from the vehicle wheel speed signals (V) and estimates tire pneumatic pressure based on the extracted resonance frequencies. When an estimated vehicle wheel pneumatic pressure falls below a predetermined critical pneumatic pressure, pneumatic pressure decline warnings are generated and displayed by a display unit (5). An update switch (41) is provided and when this update switch (41) is turned on when replacing tires (1a - 1d), the electronic control unit (4) adjusts and sets the value of the critical pneumatic pressure described above based on the resonance frequency (f 0B , f k ) extracted during this time.
