摘要： An autonomous moving object includes: at least one distance sensor configured to detect distances to first and second positions located in a moving direction of the autonomous moving object on a road surface; and a determination unit configured to calculate a difference between a differential time between a time when the distance value to the first position detected by the at least one distance sensor is greater than a first threshold value and a time when the distance value to the second position is greater than a second threshold value and a moving time in which the autonomous moving object moves between the first and second positions and to determine that the distance sensor is abnormal only when the calculated difference is equal to or greater than a predetermined value.

摘要： A method for adjusting the sensitivity of ultrasonic sensors for detecting the distance of objects from a vehicle. A sensor sensitivity is set selected so that a sonic lobe is transmitted which has an intersection with the ground. A measurement is determined using the sensor, objects in the surroundings of the vehicle having a greater distance from the vehicle than the distance from the sensor to the intersection of the sonic lobe with the ground, so the distance from the sensor to the intersection of the lobe with the ground is detected as being the shortest distance from an object. The sensitivity of the sensor is set as a function of the distance between the sensor and the intersection of the lobe with the ground, so after sensitivity is set, the lobe, at its point closest to the ground, does not fall below a specified distance from the ground.

摘要： A method for functionally testing an ultrasonic sensor on a motor vehicle in which, in a test operating mode, an ultrasonic signal is emitted whose magnitude is large enough that under conventional conditions this ultrasonic signal is reflected by a ground surface in front of the vehicle and is received again. In this way, it can easily be determined that the ultrasonic sensor is functioning properly.

摘要： A method and apparatus for automatically controlling the depth of earth grading for utilization with a grader or paver is disclosed. The method includes determination of time taken for an acoustic pulse to travel from a transducer to a reference surface and back, with this value being used to calibrate a microprocessor-controlled distance-measuring device. As the grader moves over a surface to be graded, the distance to the reference surface is constantly detected by a repeated emission and detection of such acoustic pulses. The timing of the echoed pulses is converted to addresses in a look-up table which contains control words symbolizing commands to be given to hydraulic rams carried by the grader. By implementing these commands, the depth of the blade relative to the reference surface is constantly updated, compensating for variations with the height of the reference surface. A thermistor is provided to automatically compensate for temperature variations as the grading takes place. Displays are provided for the operator of the vehicle to show what type of adjustments are being made to the blade, and whether the height of the reference surface is outside the range of sensitivity of the follower. The follower is automatically calibrated for a given blade depth by repeated incrementation of a delay time variable until a zero adjustment command is generated for the blade control.

摘要： A method and apparatus for automaticlly controlling the position of a tool carried by a machine, which in the preferred embodiment may be the blade of a grader or paver for leveling a surface at a chosen depth. The method includes determination of time taken for an acoustic pulse to travel from a transducer to a reference surface and back, with this value being used to calibrate a microprocessor-controlled distance-measuring device. As the grader moves over a surface to be graded, the distance to the reference surface is constantly detected by a repeated emission and detection of such acoustic pulses. The timing of the echoed pulses is converted to addresses in a look-up table which contains control words symbolizing commands to be given to hydraulic rams carried by the grader. By implementing these commands, the depth of the blade relative to the reference surface is constantly updated, compensating for variations with the height of the reference surface. A thermistor is provided to automatically compensate for temperature variations as the grading takes place. Displays are provided for the operator of the vehicle to show what type of adjustments are being made to the blade, and whether the height of the reference surface is outside the range of sensitivity of the follower. The follower is automatically calibrated for a given blade depth by repeated incrementation of a delay time variable until a zero adjustment command is generated for the blade control.
