A car door-triggered tire pressure detection system includes an on-board unit with an ECU unit connected to a main high-frequency transceiver module, a main display, and a door sensing module. The on-board unit does not include a vehicle low- frequency circuit and a vehicle low-frequency antenna. Multiple TPMS each include a TPMS main control unit connected to a TPMS high-frequency transceiver module. Each TPMS does not include a TPMS low-frequency circuit and a TPMS low-frequency antenna. When the door sensing module detects a car door is opened, the main display shows the tire pressure values returned by each TPMS. The problem of excessive antennas used in known wireless transmission systems is improved. When the door sensing module detects the opening of the car door, the main display shows the tire pressure values returned by each TPMS.

A method and system for collision avoidance that goes beyond automatic steering and braking. A trained artificial intelligence (AI)/machine learning (ML) system is used to detect an impending impact event that exceeds a predetermined severity threshold based on received sensor and vehicle operational data. Upon detecting such an impending impact event, vehicle systems are deployed to avoid or lessen the severity of the impending impact event. These vehicle systems include automatic steering and braking, and automatic tire flattening and vehicle anchor deployment which are intended to stop or slow the vehicle before impact.

A track system for use with a vehicle includes an attachment assembly connectable to the chassis of the vehicle having a multi-pivot assembly having a first pivot extending longitudinally and defining a roll pivot axis, and a second pivot extending laterally and defining a pitch pivot axis. A frame assembly is disposed laterally outwardly from the attachment assembly and connected thereto. The frame assembly includes at least one wheel-bearing frame member. The track system further includes at least one actuator connected between the attachment assembly and the frame assembly for pivoting the frame assembly about the roll pivot axis, a leading idler wheel assembly, a trailing idler wheel assembly, at least one support wheel assembly, and an endless track.

The invention relates to a method of estimating the load on a motor vehicle (10). The motor vehicle (10) having a wheel (12) comprising a tread (20) for rolling over a surface being driven on (14) and a first air chamber (32) in which there is a gas which by means of its gas pressure (G) counteracts de-formation of the tread (20) when the wheel (12) is rolling. The method lets gas into the first air chamber 32 over a predetermined period and estimates the load based on the change in pressure in the chamber. The object under-lying the invention is to provide a means of estimating the load on a vehicle. For this purpose the wheel (12) may have a second air chamber (38) coupled to the first air chamber (32) by a valve device (44), the first air chamber (32) extending between the tread (20) and the second air chamber (38) and the gas may flow from the second air chamber (38) into the first air chamber (32).

An apparatus for controlling a pressure on at least one tire of a vehicle based on a remaining time of travelling to a destination of the vehicle and/or an expected load of the vehicle on a subsequent trip, includes: a data acquisition module to acquire data, the data being indicative of the remaining time of travelling to the destination and/or the expected load of the vehicle on the subsequent trip. The apparatus further includes a data processing module to determine a time of changing the pressure on the at least one tire based on the acquired data and a control module to issue a control signal to initiate the change of the pressure at the determined time.

A high temperature warning system for a vehicle steer axle an air pressure supply, a normally-closed valve in fluid communication with pressure supply, a heat sensitive control capable of opening the normally-closed valve upon a predetermined temperature, the heat sensitive control mounted adjacent to the wheel end assembly in a heat exchange relationship therewith, and a warning system connected to the air pressure supply for actuation upon opening of the normally-closed valve.

A wheel for a vehicle includes a tyre and a rim for supporting the tyre. A chamber is defined between the tyre and the rim for receiving pressurized air. The wheel further includes a detecting device located inside the chamber for detecting presence of water in the wheel.

Aspects of the present disclosure are generally related to one or more systems, methods, and devices for providing an integrated tire inflation system, mounted on each tire, wheel, rim, axle, or structure of the vehicle, that communicates with a remote device (e.g., communication device located in the cab of the vehicle and/or a remote network entity) and obtains an optimal tire pressure from the network entity that is calculated to maximize fuel economy, tread life, load, or an environmental condition. In some examples, the integrated telematics system may periodically measure and transmit data associated with the tire to the communication device in the cab and/or to a network entity that may calculate the optimal tire pressure for each tire on the vehicle. The integrated telematics system may receive the optimal tire pressure information from the communication device and/or the network entity and automatically adjust the tire pressure accordingly.

Tire pressure regulation method and system for an agricultural vehicle equipped with tires. In order to improve the pressure management of the tires connected to the tire pressure regulation system, a pressure setpoint is determined by determining the characteristics of the tires, the pressure of which is intended to be regulated by the tire pressure regulation device, determining the speed of the vehicle, calculating the pressure setpoint of the tire depending on the characteristics of the tire and on the speed.

An air induction system for filtering a compressible fluid to an electromechanical component mounted on a wheel of a vehicle. The system may make use of a first plurality of float valves arranged in series in a non-linear first flowpath path, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and one being in communication with an inlet of the electromechanical component. Each of the float valves may have a buoyant float valve element therein which is responsive to change position when submerged in water, to close off its respective float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.
