Abstract
A dynamic jack reference control system may include a tilt sensor operatively associated with the vehicle so that the tilt sensor senses a tilt angle of the vehicle. A processor operatively connected to the tilt sensor produces a jack reference value based on the tilt angle of the vehicle. A speed controller operatively associated with the processor extends the at least one jack on the vehicle at a speed that is related to the jack reference value.
Claims28
A method for extending at least one jack on a vehicle, comprising:
- sensing a tilt angle of the vehicle;
- producing a jack reference value based on the sensed tilt angle, the jack reference value being a percentage of a maximum jack extension speed available for the at least one jack;
- and
- extending the at least one jack at a speed that is related to the jack reference value.
A method for leveling a jacked vehicle, comprising:
- (a) sensing a pitch angle of the vehicle;
- (b) sensing a roll angle of the vehicle;
- (c) producing a pitch reference value that is related to the sensed pitch angle of the vehicle;
- (d) producing a roll reference value that is related to the sensed roll angle of the vehicle;
- (e) extending a vehicle jack that affects at least the pitch angle of the vehicle at a speed that is related to the pitch reference value, the pitch reference value being a percentage of a maximum jack extension speed available for the vehicle jack that affects at least the pitch angle of the vehicle;
- (f) extending a vehicle jack that affects at least the roll angle of the vehicle at a speed that is related to the roll reference value, the roll reference value being a percentage of a maximum jack extension speed available for the vehicle jack that affects at least the roll angle of the vehicle;
- and
- (g) repeating (a)-(f) until the sum of the pitch and roll angles falls below a predetermined angle.
A dynamic jack reference control system for extending at least one jack on a vehicle, comprising:
- a tilt sensor operatively associated with the vehicle, said tilt sensor sensing a tilt angle of the vehicle;
- a processor operatively connected to said tilt sensor, said processor producing a jack reference value based on the tilt angle of the vehicle, the jack reference value being a percentage of a maximum jack extension speed available for the at least one jack;
- and
- a speed controller operatively associated with said processor, said speed controller being operative to extend the at least one jack on the vehicle at a speed that is related to the jack reference value.
A dynamic jack reference control system for extending at least one jack on a vehicle, comprising:
- means for sensing a tilt angle of the vehicle;
- processor means operatively associated said means for sensing a tilt angle of the vehicle for producing a jack reference value based on the tilt angle of the vehicle, the jack reference value being a percentage of a maximum jack extension speed available for the at least one jack;
- and
- speed control means operatively associated with said processor means and the at least one jack on the vehicle for extending the at least one jack on the vehicle at a speed that is related to the jack reference value.
