Abstract
Methods for controlling the traveling operation of a self-propelled ground compaction machine with the aid of a control unit which provides travel control signals to a travel drive system of the ground compaction machine. The ground compaction machine may alternatively be operated in an operator mode in which travel specifications specified by an operator via a manually operable input device are transmitted to the control unit and are transmitted by the latter in the form of travel control signals to the travel drive system of the ground compaction machine. A ground compaction machine, in particular a vibratory plate or a trench roller.
Claims26
A method for controlling the traveling operation of a self-propelled ground compaction machine with the aid of a control unit which provides travel control signals to a travel drive system of the ground compaction machine, comprising:
- operation of the ground compaction machine in an autonomous mode, in which the control unit generates travel specifications itself and transmits them in the form of travel control signals to the travel drive system of the ground compaction machine, wherein:
- operation of the ground compaction machine in the autonomous mode is only enabled by the control unit as long as a sidewall detection device of the ground compaction machine detects the presence of a sidewall projecting relative to the contact surface of the ground compaction machine, in an area in the horizontal direction transverse to a direction of travel of the ground compaction machine, and during traveling operation in autonomous mode, in the event of an abrupt loss of detection of the presence of a sidewall by the sidewall detection device, the control unit continues traveling operation in autonomous mode in a time- and/or distance-dependent manner.
A self-propelled ground compaction machine, comprising:
- a drive unit, via which the drive energy required for traveling operation of the ground compaction machine is provided;
- a ground-contacting device, via which compaction of the ground takes place, a control unit, which controls the traveling operation of the ground compaction machine, wherein:
- it has a sidewall detection device which is configured such that it detects, in an area in horizontal direction transverse to a forward direction of travel of the ground compaction machine, the presence of a sidewall projecting vertically relative to the contact surface of the ground compaction machine;
- and that the control unit is configured such that it controls the traveling operation of the ground compacting machine in an autonomous mode, wherein in the autonomous mode travel specifications are specified by the control unit, wherein further an enabling device is provided which enables or blocks the autonomous mode, which is configured such that the autonomous mode is only enabled in operating situations in which the sidewall detection device detects the simultaneous presence of a sidewall located transversely to the forward direction of the ground compaction machine.
