Abstract
An automatic guided vehicle comprising a fork carriage with a fork, a propulsion drive system, a sensor to acquire position data of objects located in a detection field and a computer. The vehicle comprises a reference member located in the detection field of the sensor rigidly secured to a common rigid frame with the sensor. The sensor periodically acquires control position data indicative of a position of the reference member. The computer periodically compares the control position data with a reference value stored in a memory.
Claims15
An automatic guided vehicle comprising:
- a fork carriage with at least one load bearing fork,
- a propulsion drive system to propel the automatic guided vehicle,
- a sensor to acquire position data of objects located in a detection field of the sensor, and
- a computer receiving position data from the sensor and controlling the propulsion drive system to automatically guide the vehicle,
- wherein the vehicle further comprises at least one reference member which is a structural part of the automatic guided vehicle located in the detection field of the sensor and detectable by the sensor, the at least one reference member and the sensor being rigidly secured to a common rigid frame so that the reference member is in a fixed position relative to the sensor,
- wherein the sensor is operative to at least periodically acquire control position data indicative of a position of the at least one reference member in the detection field of the sensor,
- and wherein the computer is operative to at least periodically compare said control position data with a reference value stored in a memory of the computer.
A method including providing an automatic guided vehicle comprising:
- a fork carriage with at least one load bearing fork,
- a propulsion drive system to propel the automatic guided vehicle,
- a sensor to acquire position data of objects located in a detection field of the sensor, and
- a computer receiving position data from the sensor and controlling the propulsion drive system to automatically guide the vehicle,
- wherein the vehicle further comprises at least one reference member which is a structural part of the automatic guided vehicle located in the detection field (7) of the sensor and detectable by the sensor, the at least one reference member and the sensor being rigidly secured to a common rigid frame so that the reference member is in a fixed position relative to the sensor,
- wherein the sensor is operative to at least periodically acquire control position data indicative of a position of the at least one reference member in the detection field of the sensor,
- and wherein the computer is operative to at least periodically compare said control position data with a reference value stored in a memory of the computer, said method including:
- at step wherein the sensor at least periodically acquires control position data indicative of a position of the at least one reference member,
- and a step wherein the computer at least periodically compares said control position data with a reference value stored in a memory of the computer.
