摘要： An electric jack load balancing method and device for reducing the difference in load carried by each jack of a pair of electric jacks while adjusting the attitude of a platform. The device includes a controller configured to reduce the difference in load carried by each jack of a pair of electric jacks. The method includes monitoring the power draws of the jack motors of the pair of electric jacks, comparing the ratio of the power draws of the jack motors to a predetermined desirable power draw ratio, and when the jack motor power draw ratio differs from the desirable power draw ratio, modifying the operation of the jacks in such a way as to decrease the difference between their actual power draw ratio and the predetermined desirable power draw ratio.

摘要： An autocalibration method for use within an electronic compass in a vehicle is disclosed. The method includes steps of initializing variables and then retrieving sensor readings from at least two axis. The method then compares the compass tilt to a predetermined threshold. Next the method will determine if the sensor reading is a minimum or maximum for the current calibration cycle. Next the method will determine if the maximum value of the sensor readings is greater than the predetermined minimum spread. Then the method will calculate an offset value for each axis and calculate a sensor value for each axis. Then the method will calculate an azimuth value with the new sensor values and determine the heading using the azimuth.

摘要： A controller commands a jack drive to extend and retract a jack leg relative to a jack base along a stroke having retraction and extension limits. The controller updates a perceived present leg position value in response to position change signals from a position change sensor. The controller occasionally applies compensation factors to the perceived present leg position value in the extension direction. The controller resets the perceived present leg position value whenever the jack leg reaches the retraction limit.

摘要： An electric actuator motor drives an actuator leg between inner and outer limits of an actuator stroke relative to an actuator base. A controller detects when the actuator leg is at one of the inner and outer stroke limits by monitoring and comparing actuator motor power draw to known actuator motor power draw values associated with the operation of an electric actuator when its leg has reached an actuator leg stroke limit. A position sensor senses changes in the position of a monitored actuator component and provides corresponding signals to the controller. The controller calculates the position of the monitored actuator component relative to the position that the monitored actuator component was in when the actuator leg was in a predetermined home position. The controller recognizes and records the concurrent position of the monitored actuator component as indicating that the actuator leg is in the home position whenever the leg reaches a stroke limit.

摘要： An electric jack ground contact detection method and device for detecting ground contact of an electric motor-driven jack as the jack is being extended to adjust the attitude of a mobile platform. The device includes a controller that monitors the electrical power draw of an electric motor-driven jack while the jack is being extended for use in adjusting the attitude of a mobile platform. The controller recognizes jack ground contact when the monitored power draw value exceeds a ground contact power draw value consistent with jack ground contact. The controller calculates the ground contact power draw value as equaling the sum of a dynamically-adjusted threshold power draw value associated with jack extension before ground contact and a power draw increase value equaling an amount of additional power that the jack is known to draw as a result of jack ground contact.
