Abstract
A method for controlling the ground grip of a wheeled loader having a pair of front wheels, a bucket, and at least one boom, comprising measuring the relative position of said front wheels with respect to the ground, detecting the reaching of a critical threshold value by measuring the relative position of the front wheels with respect to the ground, comparing the measurement of the relative position of the front wheels to a critical threshold value, and, when the measurement of the relative position of the front wheels with respect to the ground reaches the critical threshold value, inhibiting a further tilting of the bucket and a further lowering of the at least one boom.
Claims20
A method for controlling the ground grip of a wheeled loader, said wheeled loader comprising a pair of front wheels, a bucket and at least one boom, wherein the method comprises the steps of:
- measuring the relative position of said front wheels with respect to the ground;
- detecting the reaching of a critical threshold value by the measurement of said relative position of said front wheels with respect to the ground;
- comparing the measurement of said relative position of said front wheels with respect to the ground with said critical threshold value;
- and
- when the measurement of said relative position of said front wheels with respect to the ground reaches said critical threshold value, inhibiting a further tilting of said bucket and a further lowering of said at least one boom.
A system for controlling the ground grip of a wheeled loader, said wheeled loader comprising a pair of front wheels, a bucket and at least one boom, said system comprising at least one sensor device and an electronic control unit, wherein:
- said at least one sensor device is configured to measure the relative position of said front wheels with respect to the ground;
- said electronic control unit is configured to detect the reaching of a critical threshold value on the part of the measurement of said relative position of said front wheels with respect to the ground, comparing the measurement of said relative position of said front wheels with respect to the ground with said critical thresh-old value;
- and
- when the measurement of said relative position of said front wheels with respect to the ground reaches said critical threshold value, said electronic control unit is configured to inhibit a further tilting of said bucket and a further lowering of said at least one boom.
A method for controlling a wheeled loader during a dozing operation so as to control lifting of front wheels of the wheeled loader off of a ground, the method comprising:
- using at least one sensor device to measure a relative position of the front wheels with respect to the ground during the dozing operation;
- using an electronic control unit to detect when the relative position reaches a threshold value;
- and, when the relative position reaches the threshold value, using the electronic control unit to inhibit both a further tilting of a bucket of the wheeled loader and a further lowering of at least one boom, the bucket and the at least one boom configured on the wheeled loader so as to permit the dozing operation.
