Systems and methods for identifying improper implement installation

1 . A system for identifying an improper implement on a machine, the system comprising:

a machine configured for performing one or more tasks, the machine including:

a movable link configured to change a position of an implement installed on the machine;

a hydraulic system for moving the link, the hydraulic system including a hydraulic valve and a hydraulic pump; and

a pressure sensor configured to detect a pressure of hydraulic fluid for the hydraulic system and output a signal according to the detected pressure; and

a controller configured to:

receive the signal from the pressure sensor,

determine that the implement is improper for the machine on which the implement is installed due to the implement being oversized, overweight, undersized, or underweight, based on the signal from the pressure sensor and based on the position of the implement, and

generate a notification in response to determining that the implement is improper.

2 . The system of claim 1 , wherein the controller is configured to determine that the implement is improper based on signals from a plurality of sensors, each of the sensors being a non-vision sensor.

3 . The system of claim 1 , wherein the controller is further configured to determine a height of the ground and determine that the implement is improper based on the determined height of the ground and the position of the link.

4 . The system of claim 1 , further including a position sensor, the controller being configured to determine the position of the implement based on a signal from the position sensor.

5 . The system of claim 4 , wherein the controller is further configured to determine that the implement is improper when a pressure measured with the pressure sensor is greater than a pressure threshold when the implement is located at the position determined by the controller based on the signal from the position sensor.

6 . The system of claim 1 , wherein the controller is configured to determine that the implement is improper for the machine on which the implement is installed further based on signals from a swing sensor or from an engine speed sensor.

7 . The system of claim 1 , wherein the controller is configured:

to determine when the implement is oversized,

to determine when the implement is overweight,

to determine when the implement is undersized, and

to determine when the implement is underweight,

the controller being further configured to:

determine that the implement is improper based on comparing a detected pressure with a pressure threshold, the pressure threshold being associated with a posture of the machine.

8 . A detection system configured to determine presence of an improper implement on a machine, the system comprising:

a pressure sensor configured to detect a pressure of hydraulic fluid for controlling an implement and output a signal indicative of the pressure; and

a controller configured to:

receive the signal from the pressure sensor,

determine that the implement is improper for the machine on which the implement is installed due to the implement being oversized, overweight, or oversized and overweight, based on the signal from the pressure sensor, and

generate a notification in response to determining that the implement is improper.

9 . The system of claim 8 , wherein the controller is configured to determine that the implement is improper further based on a detected position of the implement.

10 . The system of claim 8 , wherein the controller is configured to determine that the implement is improper when the signal indicates that the pressure of hydraulic fluid exceeds a maximum pressure threshold that is associated with a posture of the machine or with a movement of the machine.

11 . The system of claim 8 , wherein the controller is configured to generate the notification when the pressure of hydraulic fluid has exceeded a maximum pressure threshold more often than a threshold number of occurrences.

12 . The system of claim 8 , wherein the controller is configured to perform the determination that the implement is improper based on the pressure of the hydraulic fluid sensed while the implement is in contact with the ground.

13 . The system of claim 8 , wherein the controller is configured to determine that the implement is improper by receiving the signal while the implement is not in contact with the ground.

14 . A method for identifying installation of an improper implement on a machine, the method comprising:

detecting a position of a movable link for positioning an implement with a position sensor;

determining a position of the implement based on the position of the movable link;

detecting a pressure of hydraulic fluid, flow of the hydraulic fluid being controlled for positioning the implement; and

based on the determined position of the implement and the detected pressure, identifying that the installed implement is improper for the machine on which the implement is installed.

15 . The method of claim 14 , further including comparing the detected pressure of hydraulic fluid to an expected hydraulic fluid pressure associated with the position of the implement.

16 . The method of claim 15 , wherein the position of the implement is a position in which the implement is expected to be above the ground.

17 . The method of claim 16 , wherein the improper implement is identified based on the detected pressure being less than the expected hydraulic fluid pressure.

18 . The method of claim 15 , wherein the position of the implement is a position in which the implement is expected to be in contact with the ground.

19 . The method of claim 14 , wherein the improper implement is identified without the use of a vision-based sensor.

20 . The method of claim 14 , further including generating a notification in response to identifying the improper implement, the notification indicating presence of the improper implement.
