A monitoring system for a combination vehicle comprises at least one image capture device mounted on a tractor, which has a trailer mounted control system within its field of view. The trailer mounted control system has a visual indicator. A controller is associated with the at least one image capture device. The controller captures images of the visual indicator, determines if the visual indicator meets a predetermined event condition and provides notification to at least one of a driver of the tractor and a remote fleet operator in response to the visual indicator meeting the predetermined condition.

A tire state monitoring system includes: tire state acquisition devices installed on tires of a host vehicle, each of the tire state acquisition devices being configured to acquire a tire state quantity; a monitoring device configured to receive an output signal from each of the tire state acquisition devices and perform predetermined processing; and an alerting device configured to issue an alert to a following vehicle. In addition, the monitoring device causes the alerting device to operate when a predetermined abnormality has arisen in the tire state quantity.

An example of a vehicle tire gauge system includes a tire pressure monitoring system in a vehicle. A transceiver in the vehicle is for transmitting a tire pressure sensed by the tire pressure monitoring system to a paired wearable device. A tire pressure table is stored in a model of an application having a view on the wearable device. A haptic feedback generator in the wearable device is responsive to the tire pressure reaching a first value, wherein the first value is contained in the tire pressure table.

A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire. The pressure sensing assembly includes a housing, a pressure transmitting member, a sensing chamber defined by the housing and the pressure transmitting member, and a sensing element. The pressure transmitting member is coupled the housing and has a central portion offset from the plane in a first direction. The sensing element is offset from the plane in a second direction opposite the first direction. The pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber.

Disclosed embodiments include apparatuses, systems, and methods for providing a sound indicative of a pressure of a tire relative to a target pressure. A target pressure specifier is configured to specify a target pressure for a tire and generate a target pressure signal indicative of the target pressure. A pressure monitor is configured to receive the target pressure signal, a current pressure signal indicative of a current pressure of the tire, and an indicator of a deliberate change in the current pressure and compare the current pressure signal with the target pressure signal responsive to the indicator. A status signal is generated indicative of a status of the current pressure signal relative to the target pressure signal. An audio generator is configured to receive the status signal and to generate a sound audible outside of the passenger compartment of the vehicle that is indicative of the status signal.

A method of communicating configuration data of a tire pressure monitoring device configured to be affixed to a wheel in use. The method includes, at the tire pressure monitoring device, receiving a request to confirm configuration data, and responsive to receipt of the request to confirm configuration data, transmitting a configuration data signal which encodes the configuration data. The configuration data signal is configured to be received and understood by a human. The configuration data signal is indicative of any of an aircraft wheel location at which the tire pressure monitoring device is intended to be located, and a security code representative of security parameters of the tire pressure monitoring device

A wireless sensor for a wheel end assembly of a heavy-duty vehicle is provided. The wheel end assembly includes a wheel hub and a hub cap mounted on the wheel hub. The sensor includes mounting means disposed in the hub cap. Sensing means are mounted on the mounting means to sense at least one condition of the vehicle. A processor is mounted on the mounting means and is electrically connected to the sensing means to process data from the sensing means. Communication means are mounted on the mounting means and are electrically connected to the processor to communicate the processed data to a user. An electrical energy storage device is mounted on the mounting means and is electrically connected to the sensing means, the processor and the communication means, enabling the sensor to be independent from the vehicle power supply. The sensor also accommodates components of a tire inflation system.

A wireless vehicle data communications device is adapted for mounting on a wheel hub assembly of a vehicle. The vehicle data communications device includes a housing, a microprocessor located inside the housing, a signal transmitting device, and a signal receiving device. A self-generating electrical power supply is located within the housing and functions to supply electrical power to components of the vehicle data communications device.

A vehicle wheel illumination assembly includes a light source located on the body of a vehicle near the wheel well and oriented to direct light onto a wheel assembly having a tire. A tire pressure indicator detects tire pressure of the tire. The light source illuminates the wheel assembly with a desired color to indicate a tire pressure status based on the detected tire pressure. A photoluminescent material is located on the wheel assembly and configured to luminesce in response to excitation by the light assembly.
