    • PROBLEM TO BE SOLVED: To provide a controller for an autonomous-running service vehicle that drives a service vehicle to run according to a predetermined running pattern in a scheduled running area and properly calibrates outputs of an angular velocity sensor.SOLUTION: The controller drives the service vehicle to run straight according to the predetermined running pattern in the scheduled running area based on running directions and running distances calculated based on outputs of a Yaw sensor generating outputs showing angular velocities generated around a vertical axis at a center-of-gravity position of the service vehicle and outputs of a wheel velocity sensor generating the outputs showing wheel velocities. Meanwhile the controller determines whether or not a difference between a scheduled running distance L1 scheduled in the predetermined running pattern and an actual running distance L2 exceeds an allowable error value α in straight running in controlling the autonomous-running service (S10 to S18), and corrects center values of the outputs of the Yaw sensor when the difference is determined to exceed the allowable error value (S22).

    • PROBLEM TO BE SOLVED: To provide a reliable method for detecting the position of a vehicle in a storage facility by low cost. SOLUTION: By this detection method, the current position of a vehicle is detected by detecting motion vectors of the vehicle, determining the reference position of the vehicle detecting absolute position when the vehicle passes a point at which a measure strip is installed, and seeking the vectorial summation of the motion vectors on the basis of the reference position. The detection of the absolute position is carried out by means of a sensor device which interacts in a non-contacting manner with the respective reference marking (MS) of the measure strip installed in the vehicle, and each reference marking (MS) has reflective and non-reflective areas (R1, R2; D) which are scanned simultaneously by the vehicle by means of at least two signals (ST1, ST2). The coordinates (x, y) of the reference position and the angle of passage (α) of the vehicle to the measure strip are measured by evaluating the time profile of the reflected intensity of the signals (ST1, ST2).

    • PROBLEM TO BE SOLVED: To enable a self-running type vacuum cleaner to surely return to a charging base when the residual quantity of a battery has decreased to a certain degree. SOLUTION: In this self-running type vacuum cleaner, when the residual quantity of the battery is judged to be an amount for which a predetermined margin amount is added to a battery amount required for returning to the position of the charger or higher, as shown by (A), a current is fed to a left driving wheel motor and a right driving wheel motor for 80% of the period of time (ON state), and the feeding of the current is stopped for 20% of the period of time (OFF state). In the meantime, when the residual quantity of the battery is judged to be lower than the amount for which the predetermined margin amount is added to the battery amount required for returning to the position of the charger, as shown in (B), the current is fed for 40% of the period of time (ON state) to the left driving wheel motor and the right driving wheel motor, and the feeding of the current is stopped for 60% of the period of time (OFF state).

    • PURPOSE:To avoid misconversion of direction generated in the middle of a traveling course, by inhibiting and releasing the control for conversion of direction on the basis of the traveling course information which is calculated and stored after teaching previously the outer circumference of a working area. CONSTITUTION:An unmanned truck is provided with copying sensors 5A and 5B which detect the boundary between a worked area and an unworked area, a distance sensor 7 which detects the distance traveled of the truck, a direction sensor 8 for traveling direction of the truck, and a contact type obstacle sensor 6. The truck travels along the outer circumference 12D of a working area. Then the teaching is given to the circumference 12D by sampling the direction information theta detected by the sensor 8 and for each prescribed traveled distance l0 which is detected by the sensor 8. The traveling course distances l1-ln are calculated and stored for each course on the basis of the information theta, the distance l0 and the work width (d) of a traveling course. When the actual traveled distance of each course is nearly coincident with the stored distances l1-ln or when the sensor 6 detects an obstacle, the traveling direction is automatically converted by a hydraulic cylinder 9.
