A road inclination estimating apparatus is configured to acquire power spectrum density of vertical vibration by a frequency analysis based on the detected vertical acceleration of the sprung mass of a vehicle. The apparatus is configured to determine that a first estimation condition is satisfied, when the power spectrum density has two of the acquired peak frequencies, wherein, one of the two of the peak frequencies is within a predetermined first frequency range, and the other one of the two of the peak frequencies is within a predetermined second frequency range.

When information related to road surface conditions is conveyed from a vehicle body side system to a tire-mounted sensor and the tire-mounted sensor determines the road surface condition, an integrated voltage value is corrected based on the information related to the road surface condition. It is thus possible to estimate the road surface condition more accurately. Furthermore, in as much as the road surface condition is estimated at each tire-mounted sensor, the road surface condition can be estimated for each wheel.

Systems and methods cause a component of a vehicle to activate. The systems and methods receive audio data generated by a microphone of the vehicle, where the audio data represents sound of the component. Based on the audio data, a condition of the vehicle or the component may be determined, and based on the condition, the vehicle may be commissioned for use or decommissioned.

This monitoring device comprises: an acceleration acquisition unit for acquiring acceleration data of a vehicle traveling along a track; an acceleration effective value acquisition unit for acquiring a plurality of acceleration effective values obtained by applying a bandpass filter for each of a plurality of constant specific bandwidths to the acceleration data; a corrected acceleration calculation unit for calculating a corrected acceleration on the basis of each of the acceleration effective values of the respective constant specific bandwidths and predetermined correction coefficients corresponding to the respective constant specific bandwidths; and an abnormality detection unit for detecting an abnormality of the vehicle or of the track on the basis of the magnitude of the corrected acceleration.

A method for determining a road condition is carried out aboard a vehicle driving on the road and comprises the following steps: capturing the noise created by the friction between at least one tire and the road; analyzing the noise signal in the high frequency range to determine whether the road condition is dry or not; and, in case the road condition is not dry, analyzing the noise signal in the low frequency range to determine whether to road condition is wet or damp.

A method for determines the drive train sensitivity of a drive train of a motor vehicle. A vehicle body is placed in longitudinal oscillations in the direction of travel and a parameter for the drive train sensitivity is determined as a function of the determined longitudinal accelerations of the vehicle body and the resultant angular accelerations of a transmission input shaft of a transmission of the motor vehicle.
