Abstract
Disclosed are various embodiments for compensating footprint length for inflation pressure changes in tires. Various embodiment can receive a tire pressure measurement for a tire and an uncompensated footprint length for the tire. Various embodiments can calculate an inflation difference between the tire pressure measurement and a target tire pressure for the tire. Then, various embodiments can calculate an inflation ratio by at least on finding a quotient of the inflation difference over the target tire pressure for the tire. Based at least on the inflation ratio, various embodiments can determine a compensated footprint length. Then, various embodiments can send the compensated footprint length to a vehicle system.
Claims15
A method, comprising:
- receiving, from a sensor, a tire pressure measurement for a tire;
- receiving, from the sensor, an uncompensated footprint length for the tire;
- calculating an inflation difference between the tire pressure measurement and a target tire pressure for the tire;
- calculating an inflation ratio by at least on finding a quotient of the inflation difference over the target tire pressure for the tire;
- determining a compensated footprint length based at least in part on the inflation ratio;
- and
- sending the compensated footprint length to a vehicle computing system, wherein sending the compensated footprint length to the vehicle computing system causes a pressure regulator to adjust the tire pressure of the tire to achieve the compensated footprint length by at least:
- sending, to the vehicle computing system, an instruction to modify the tire pressure, wherein the instruction to modify the pressure includes an instruction to increase the tire pressure by adding gasses to the tire or to decrease the tire pressure by releasing gasses from the tire;
- receiving, from the sensor, an updated footprint length for the tire;
- and
- sending, to the vehicle computing system and based at least on a determination that the updated footprint length matches the compensated footprint length, an instruction to cease modifying the pressure.
A system, comprising:
- a computing device comprising a processor and a memory;
- and
- machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:
- receive, from a sensor, a tire pressure measurement for a tire;
- receive, from the sensor, an uncompensated footprint length for the tire;
- calculate an inflation difference between the tire pressure measurement and a target tire pressure for the tire;
- calculate an inflation ratio by at least on finding a quotient of the inflation difference over the target tire pressure for the tire;
- determine a compensated footprint length based at least in part on the inflation ratio;
- and
- send the compensated footprint length to a vehicle computing system, which causes a pressure regulator to adjust the tire pressure of the tire to achieve the compensated footprint length by at least:
- sending, to the vehicle computing system, an instruction to modify the tire pressure, wherein the instruction to modify the pressure is an instruction to increase the tire pressure by adding gasses to the tire or to decrease the tire pressure by releasing gasses from the tire;
- receiving, from the sensor, an updated footprint length for the tire;
- and
- sending, to the vehicle computing system and based at least on a determination that the updated footprint length matches the compensated footprint length, an instruction to cease modifying the pressure.
A non-transitory, computer-readable medium, comprising machine-readable instructions that, when executed by a processor of a computing device, cause the computing device to at least:
- receive, from a sensor, a tire pressure measurement for a tire;
- receive, from the sensor, an uncompensated footprint length for the tire;
- calculate an inflation difference between the tire pressure measurement and a target tire pressure for the tire;
- calculate an inflation ratio by at least on finding a quotient of the inflation difference over the target tire pressure for the tire;
