Monitoring Systems for Tire Performance

A tyre monitoring sensor for vehicles that reduces cost by using an ultra-wideband (UWB) device that can switch between sensing, communication, and ranging modes. The sensor can measure tyre properties, transmit data, and determine its location on the vehicle using UWB. This eliminates the need for separate components to perform these functions. The sensor alternates between sensing, communicating, and ranging modes. After initial ranging to associate the sensor with a wheel, it only ranges on user input.

A tire pressure monitoring system with an externally replaceable battery in the valve stem. The valve stem has a removable core that holds the battery. The sensor is separate from the stem. The stem connects to the sensor via spring-loaded terminals. This allows battery replacement without removing the tire or stem. The stem interior cavity retains the battery. The stem core removably secures the battery. The stem is separated from the sensor by a connector. The stem has a port for airflow. The battery provides power to the sensor inside the stem.

A method to monitor wheel balance in vehicles using existing TPMS sensors without additional hardware. The method involves measuring the noise of the raw acceleration signal from each wheel and comparing the variation to detect unbalanced wheels. It uses the standard deviations of the acceleration signals transmitted by the TPMS wheel units. If the variation exceeds a threshold over multiple iterations, indicating simultaneous noise on both wheels, it's interpreted as a bad road rather than wheel imbalance. This prevents false warnings from road vibrations. The reference averages are reset if both wheels exceed a threshold simultaneously to avoid false warnings from road conditions.

Automatic programming of tire pressure monitoring sensors (TPMS) for vehicles that saves time and simplifies the programming process compared to manual selection of programming steps. The system uses a programming tool with a database of TPMS programs for different vehicle brands. When a new TPMS is connected, the tool issues a verification code. The TPMS checks if the code matches a pre-set value. If so, the TPMS sends back an installation code. The tool then retrieves the correct program for the vehicle brand from the database and sends it to the TPMS for programming.

A tire pressure monitoring system that provides more accurate and contextual tire pressure alerts based on environmental conditions like temperature, humidity, and weather. The system uses sensor data from the tires along with external environmental data to determine if a tire pressure warning is necessary. This allows adjusting the threshold for what constitutes an underinflated tire based on factors like cold weather, rain, and snow. The goal is to avoid false positives and unnecessary alerts in certain conditions where slight pressure drops may be normal.

Power-saving tire pressure monitoring system that reduces energy consumption by intelligently controlling the sensor operation based on vehicle acceleration and time of day. The system has a microcontroller that monitors sensors like pressure, temperature, and acceleration. It uses a real-time clock to determine the time and day. The microcontroller puts the sensor system into a sleep state when the vehicle is stationary or at night to save power. It wakes up the sensors when acceleration indicates driving or it's daytime. This allows the system to operate without affecting the warning function while minimizing power consumption.

Tire pressure monitoring system for vehicles with multiple tires that improves reliability for long wheelbase vehicles with distant tires. The system uses a master sensor near the vehicle's electronics and slave sensors further out. The master initiates tire pressure sensing and commands the slaves to measure. The slaves transmit data wirelessly to the master which then sends it to the central processing unit. This reduces attenuation compared to direct transmission from faraway sensors. If a sensor detects a fault, it sends an alert on a separate frequency to avoid interference.
