摘要： In an automatic draft control system for positioning a hitch, velocity feedback loop techniques are employed to control the rate of movement of the hitch. When the system is operating in an open loop position control mode, a switch (72,74) mounted on a tractor fender enables an operator manually to control raising/lowering of the hitch for the purpose of attaching an implement (10). Hitch position is sensed (70) and a microprocessor (40) calculates the first derivative of the hitch position signal to determine actual hitch velocity. The actual velocity is subtracted from a desired velocity value to obtain a velocity error signal. The error signal is subjected to an integral control algorithm and the integrated value is used to energize RAISE or LOWER solenoids (76,78) controlling a valve (44) which raises or lowers the hitch. When the actual hitch velocity is equal to or greater than the desired hitch velocity, the integrated value is saved. When the next raise/lower sequence is initiated the integrator is reset to the saved value. This eliminates delays in starting hitch motion. The desired velocity value may be derived from the setting of a drop rate potentiometer (58) in which case a drop rate value is added to the integrated error signal with the result being used to modify a hitch movement command that energizes the "LOWER" solenoid (78), thereby limiting the hitch drop rate when the system is operating in a closed loop position/draft control mode.

摘要： A cold start control apparatus for diesel engines (26) includes a cold start switch (12), engine temperature and speed sensors (28, 24) and a transistor (16) all connected to a programmable controller (14). The transistor (16) is connected in a series circuit with a cold start relay (22) and the series circuit is connected to the run/crank positions of an ignition switch (10). The relay (22) has a pair of contacts through which a battery voltage (+12B) may be applied to a cold start assist apparatus provided for the engine. The cold start assist apparatus may be a thermostart element (30) such as a glow plug ignitor, or a solenoid controlled ether injection system (32). A permanent memory in the controller (14) stores an indication of the type of cold start assist apparatus provided for the engine. The controller (14) senses for actuation of the cold start switch (12) and applies a signal to the transistor (16) thus turning it on if (1) the ignition key is in the run or crank position, (2) the engine is cold and (3) the cold start assist apparatus is a thermostart element (30). On the other hand if the cold start assist apparatus is an ether injection system (32), the controller (14) responds to actuation of the cold start switch (12) to apply a signal to the transistor (16) only if (1) the engine is cold, (2) the ignition switch is in the crank position and (3) the engine speed is at least as great as a predetermined speed. While the transistor (16) is on, voltage is applied to the cold start assist apparatus. The controller (14) generates one signal to turn the transistor (16) on for each sensed actuation of the cold start switch (12). The duration of the signal is determined by the stored indication of the type of cold start assist apparatus provided for the engine (26).

摘要： In an automatic hitch control system wherein a hitch (14) is raised or lowered in response to operation of a valve (44), and the valve (44) is controlled by solenoids (76,78) which are selectively energized by connecting them to ground through switch drivers (92), a safety disconnect relay (90) is provided for preventing uncommanded motion of the hitch (14) such as might occur if the lead between a solenoid (76,78) and its driver (92) should be grounded or if the driver should fail in an "on" state. The relay (90) has contacts connected between the solenoids (76,78) and the positive voltage for operating them. A microprocessor (40) senses hitch position, the position of a quadrant lever (50) and the speed of the vehicle carrying the hitch. From the conditions sensed, the microprocessor (40) determines if the vehicle is moving, if the hitch is captured, if the hitch is moving and whether the hitch control system is in an open-loop control mode in which manual switches (72,74) may be used to control hitch movement. If the hitch is not captured, or the hitch control system is in the open-loop mode, and uncommanded downward hitch motion is detected, the microprocessor (40) energizes the safety disconnect relay (90) to disable the hitch valve (44) thereby preventing uncommanded downward motion of the hitch. When the hitch (14) is captured and the control system is in a closed-loop control mode, feedback signals from the hitch act through a closed-loop to maintain the hitch at the position specified by the quadrant lever (50).

摘要： A vehicle transmission system having shift levers (92, 96) coupled to couplers (65, 55) for selection of ranges of gear speed ratios and electro-hydraulic powershift clutches (60) for selection of a gear speed ratio within the selected range is provided with controls for avoiding unexpected speeds or speed changes under certain conditions. When an operator depresses a clutch pedal (78), shifts a shift lever (92, 96) and then changes his mind and shifts the shift lever back to its original position before releasing the clutch pedal (78) above a threshold point, the microprocessor (80) selects the powershift gear in effect at the time the clutch pedal (78) was depressed. This "change of mind" logic uses first and second registers; first means for transferring the powershift gear value from the first register to the second register and entering a new powershift gear value in the first register the first time the range shift lever (92; 96) is shifted from one position to another during a given depression of the clutch pedal (78), and second means for transferring the value in the second register back to the first register if the range shift lever (92; 96) is also shifted back from said other to said one position during the given depression of the clutch pedal (78).

摘要： An automatic draft control for controlling the position of a vehicle-mounted hitch (14) includes a slip override circuit (116) responsive to a wheel signal (80,82) for modifying a hitch position command so that hitch draft is reduced by raising the hitch when the degree of vehicle wheel slip exceeds a threshold value. The slip is determined by measuring theoretical (no-slip) ground speed with a sensor (80,82) which senses the rate of rotation of the vehicle rear axle, and measuring true ground speed with a radar unit (84) mounted on one side of the vehicle. Because the radar unit (84) does not indicate the speed of the center line of the vehicle as it turns, the slip signal is prevented from modifying the hitch position command if the hitch (14) is raised since the hitch is usually raised when turning and there is no need to modify the position command with the slip signal when the hitch is raised. The true ground speed is automatically and repeatedly divided by the rate of rotation of the vehicle rear axle when conditions are such that wheel slippage is unlikely. The multiple divisions produce plural indications of a correction factor. These indications are filtered to obtain a correction factor which accounts for variations in the effective rolling radius of the wheels. Once the correction factor has been determined it is applied to the wheel speed sensor output to calculate the theoretical ground speed of the vehicle.

摘要： In a transmission system, a solenoid controlled electro-hydraulically actuated creeper mechanism coupler (15) permits selection of very low speeds and provision is made to prevent creeper gear engagement/disengagement, unless controlled by the operator and then only if specified conditions exist. Current flow through the solenoid (83) which actuates the creeper mechanism (70) is monitored at all times to provide a controlled engagement/disengagement of the creeper mechanism (70) in the event the monitored conditions are not within prescribed limits. The current is monitored as the creeper solenoid (83) is energized, while it is energized and when it is not energized so that short or open circuit conditions may be detected before they can cause an unexpected engagement or disengagement of the creeper mechanism (70).
