SYSTEM AND METHOD FOR AUTOMATIC PRESSURE MANAGEMENT
A pressure management system for a tire assembly on a vehicle including: a housing unit, a pump, and a power interface.
1 . A system, comprising:
a wheel-end inflation system mounted to a wheel of a vehicle, comprising:
a pump configured to inflate a tire mounted to the wheel;
a local control system configured to control the pump based on a set of control instructions; and
a set of sensors configured to collect measurements about the wheel-end inflation system; and
a communications system mounted to the vehicle and configured to:
transmit the measurements to a remote control system configured to dynamically determine new control instructions based on the measurements;
receive the new control instructions from the remote control system; and
transmit the new control instructions to the local control system, wherein the local control system controls the pump based on the set of new control instructions.
2 . The system of claim 1 , wherein the new control instructions comprise a target pressure.
3 . The system of claim 1 , wherein the new control instructions are dynamically determined during operation of the vehicle.
4 . The system of claim 1 , wherein the measurement transmission is based on a wheel rotation speed.
5 . The system of claim 4 , wherein the measurements are transmitted when the wheel rotation speed is zero.
6 . The system of claim 1 , wherein the local control system is configured to wirelessly transmit measurements to the communications system.
7 . The system of claim 1 , wherein the communications system is mounted to the wheel-end inflation system.
8 . The system of claim 1 , wherein the pump is driven by an eccentric mass moving relative to the pump during vehicle operation.
9 . The system of claim 8 , wherein the local control system is powered by a battery mounted to the wheel of the vehicle.
10 . The system of claim 1 , wherein the local control system:
controls the pump based on an operation mode; and
dynamically switches operation modes based on the measurements.
11 . The system of claim 1 , wherein the communications system is further configured to send notifications to a user device.
12 . A system, comprising:
a set of tire inflation systems, each configured to mount to a wheel of a vehicle, wherein each tire inflation system comprises:
a pressurized fluid source;
a set of sensors configured to sample a set of measurements; and
a processing system configured to control operation of the pressurized fluid source based on a set of tire pressure targets; and
a remote controller, remote from the set of tire inflation systems and configured to:
determine a new set of tire pressure targets based on each set of measurements; and
transmit the new set of tire pressure targets to a plurality of tire inflation systems during operation of the vehicle, wherein the processing system of each tire inflation system is configured to control operation of the respective pressurized fluid source based on the new set of tire pressure targets.
13 . The system of claim 12 , wherein the set of tire pressure targets comprise a set of tire pressure ranges.
14 . The system of claim 12 , wherein each tire inflation system additionally comprises a valve fluidly connected to the pressurized fluid source, and wherein the processing system is additionally configured to control the valve.
15 . The system of claim 14 , wherein the valve is configured to facilitate a flow of air.
16 . The system of claim 12 , wherein the new set of tire pressure targets comprises different tire pressure targets for each tire inflation system in the set of tire inflation systems.
17 . The system of claim 12 , wherein each tire inflation system in the set of tire inflation systems is mounted to a wheel hub.
18 . The system of claim 12 , wherein the new set of tire pressure targets are determined based on route parameters.
19 . The system of claim 18 , wherein the new set of tire pressure targets are determined based on data captured by tire inflation systems on other vehicles.
20 . The system of claim 19 , wherein the data captured by tire inflation systems on other vehicles comprises historic operation data.
