Antiskid control unit and data collection system for vehicle braking system
First Claim
1. A method of providing information related to the operation of a wheel on an axle of a moving vehicle, the wheel including a wheel brake and a tire, the method comprising the steps of:
- measuring at least one of wheel speed, tire pressure, brake torque and brake temperature and correspondingly generating at least one of wheel speed, tire pressure, brake torque and brake temperature data, respectively;
storing said at least one of wheel speed, tire pressure, brake torque and brake temperature data;
transmitting said at least one of wheel speed, tire pressure, brake torque and brake temperature data from a transmitting antenna associated with a radio frequency data port at the wheel;
receiving said at least one of wheel speed, tire pressure, brake torque and brake temperature data from said transmitting antenna at a receiving antenna associated with said radio frequency data port at the wheel; and
providing said at least one of wheel speed, tire pressure, brake torque and brake temperature data to said radio frequency data port at the wheel to provide access at the wheel to said at least one of corresponding wheel speed, tire pressure, brake torque and brake temperature data.

Abstract
A wheel speed transducer including a magnetic device associated with a wheel and a sensor device associated with the axle of the wheel provides data indicative of the velocity of the wheel. A processor located at the axle receives the wheel speed data and processes it to perform antiskid control functions. The velocity data is stored in a data concentrator also associated with the axle. A tire pressure sensor, a brake temperature sensor and a brake torque sensor, each associated with the wheel, send data to the processor at the axle, for storage in the data concentrator. A transmitting antenna associated with the axle and in communication with the data concentrator transmits stored data to a receiving antenna associated with the wheel. A data port at the wheel and in communication with the receiving antenna provides an interface to an external device for receiving the data.

9. A method of providing information related to the operation of a wheel on a hollow axle of a moving vehicle, the moving vehicle including an antiskid unit operative to generate operation information data related to operation of the wheel, the antiskid unit being associated with the hollow axle, and a data concentrator operatively connected to the antiskid unit and configured to receive and store the operation information data from the antiskid unit, said data concentrator being associated with the hollow axle, the method comprising the steps of:
-
transmitting the operation information data from the data concentrator from a transmitting antenna of a radio frequency data port at the wheel; receiving the operation information data transmitted from said transmitting antenna at a receiving antenna of the radio frequency data port at the wheel; and providing the operation information data received at the wheel to said radio frequency data port at the wheel to provide access to the operation information data at the wheel.
