System and method for preventing power head rollover during a dump operation by monitoring front struts

摘要

A system is disclosed for preventing power head rollover of a vehicle during a dump operation. The system includes a dump signal indicating when the vehicle is dumping, a strut sensor reading indicating a condition of the front struts, and a controller receiving the dump signal and strut readings, and activating a warning signal when the dump signal indicates the vehicle is dumping and the strut reading indicates the front wheels may be lifted off the ground. The strut sensors can be height, pressure or other types of sensors. The controller can also disable further lifting of the dump body when the dump signal indicates the vehicle is dumping and the strut sensor indicates the front wheels may be lifted off the ground. The system can include a strut limit, and the controller can act based on comparing the strut reading to the strut limit.

1. A system for preventing power head rollover of a dump vehicle during a dump operation, the dump vehicle including an operator cab and front wheels coupled to a front frame, a dump body and rear wheels coupled to a rear frame, and front struts coupling the front wheels to the front frame, the front frame being coupled to the rear frame, the system comprising:
a dump operation sensor generating a dump signal indicating when the dump vehicle is performing a dump operation; a front strut height sensor generating a front strut height reading indicating a height of the front struts; a first front strut height limit; a second front strut height limit, the second front strut height limit being greater than the first front strut height limit; a controller configured to receive the dump signal and the front strut height reading;wherein when the front strut height reading is less than the first front strut height limit, the controller does not activate a warning signal or disable lifting of the dump body;
when the dump signal indicates that the dump vehicle is performing a dump operation and the front strut height reading exceeds the first front strut height limit and is less than the second front strut height limit, the controller activates the warning signal but does not disable further lifting of the dump body; and when the dump signal indicates that the dump vehicle is performing a dump operation and the front strut height reading exceeds the second front strut height limit, the controller activates the warning signal and disables further lifting of the dump body.
