A tire communication apparatus of an embodiment includes a pressure sensor, a first wireless control unit and a second wireless control unit. The pressure sensor detects an air pressure of a tire. When receiving a wireless carrier sent out from a monitoring terminal by a first communication method, the first wireless control unit generates a trigger signal. The second wireless control unit is activated by the trigger signal being inputted when the second wireless control unit is stopped, acquires a detection result of the air pressure of the tire from the pressure sensor and transmits the detection result to the monitoring terminal by a second communication method different from the first communication method.

The systems and methods may transmit a plurality of locationing pulse requests from a mobile device in a vehicle to an audio system of the vehicle during a period of operation of the vehicle. The audio system may have an array of speakers disposed inside the vehicle, and the locationing pulse requests may include a request to emit a locationing pulse from the array of speakers. The systems and methods may further receive the locationing pulse at a microphone of the mobile device; and generate or update a vehicle usage profile based upon the receiving operation. The vehicle usage profile may include occupancy data of one or more seats inside the vehicle. The systems and methods may further transmit a recommendation to a person associated with the mobile device. The recommendation may be based upon the vehicle usage profile, and may relate to vehicle operation or insurance.

The systems and methods may determine an identity associated with each of the non-driver passengers, and subsequently transmit a request to share costs of the vehicle during the period of operation of the vehicle to the mobile device.

The technology relates to the prediction and handling of tire blowouts for vehicles operating in a self-driving (autonomous) mode. Aspects involve determining a likelihood of tire failure, including actions the vehicle may take to reduce the likelihood of failure. Pre-trip and real-time system checks can be taken. A vehicle model including the tires may be employed in blowout prediction. The on-board system may store received data and detected sensor regarding tire pressure and temperature, which can be evaluated based on the model in order to avoid or minimize the likelihood of a blowout given various factors. The factors can include the load weight and distribution of cargo, current and upcoming weather conditions on the route, the number of miles traveled per tire, and detected obstructions, such as potholes, debris or other roadway impairments. Should a blowout occur, the autonomous system may immediately take any necessary corrective action.

A device for determining an operating state of an automobile from automobile data available on a CAN network of the vehicle, the device including a computer for mathematically processing the data to determine the operating state of the vehicle. The computer is hosted in a smartphone, a specific application for processing the data using the computer is implemented in the smartphone, recovery of the data from the CAN by the smartphone is carried out via a wired or wireless link, and the smartphone displays, via a graphical interface thereof, the operating state of the vehicle.

A system for influencing a vehicle position when travelling along a subsurface includes a vehicle structure including left and right wheels, a tire inflation system for the supply of the corresponding tires of each individual wheel with a specified tire inflation pressure, and a sensor device for determining a transverse tilt of the vehicle structure with respect to the travelled subsurface. The sensor device is configured to provide a transverse tilt magnitude that reflects the determined transverse tilt and operably communicates it to a control unit. The control unit operably adapts the tire inflation pressure specified for the left and right wheels by controlling the tire inflation system in accordance with the transverse tilt magnitude in such a way that the vehicle structure is tilted in the sense of a reduction of the determined transverse tilt with respect to the travelled subsurface.

A system for detecting the operation of the motor or engine of a motor vehicle equipped with at least one tire-pressure-monitoring-system transmitter including: a low-frequency stage including a resonant stage connected in series with an antenna, a processing stage, a first switch and a second switch, the first switch being connected to at least two capacitors so as to control the parallel connection of at least one of the capacitors, the second switch being connected to at least two resistors so as to control the parallel connection of at least one of the resistors, outputs of the low-frequency stage being arranged to receive input from the processing stage, in order to transfer the perceived signal to a processor of the signal, which is configured to compare the level of the perceived signal to a preset threshold level.

A tire air pressure warning device includes a tire air pressure sensor and at least one controller that warns a driver that a tire air pressure detected by the tire air pressure sensor has dropped to or below a first prescribed pressure. The at least one controller further notifies the driver is reduction in the tire air pressure upon determining that the tire air pressure has dropped to or below a second prescribed pressure, which is above the first prescribed pressure. The at least one controller further determines whether the tire air pressure has dropped to or below the second prescribed pressure based on when the tire air pressure is at or below the second prescribed pressure in an ignition switch on state, and whether the tire air pressure has dropped to or below the second prescribed pressure when the ignition switch is turned off.
