Road inclination estimating apparatus of vehicle
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.
Road surface condition estimation device
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.
Using sound to determine vehicle health
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.
