Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To sufftciently supply energy to the secondary side of a transformer even when a battery voltage has dropped. SOLUTION: Switching frequency of a MOS transistor is set low with drop in battery voltage. By setting the switching frequency low according to drop in battery voltage, primary current is sufficiently increased not only when battery voltage is high but also when battery voltage is low. Therefore, the total energy W stored on the primary side of the transformer can be increased even when the battery voltage has dropped. Practically, the frequency of saw tooth waves formed with a saw tooth wave forming circuit 163 in a PWM control circuit according to drop in battery voltage is dropped with a frequency changing circuit 185b.

Abstract: PURPOSE:To maintain the real time properties of a robot by positioning the robot hand after correction of parallel links and then correcting the error between the motor target value and the present position of the hand. CONSTITUTION:An error corrector 50 obtains the errors between the command value of a robot controller 40 and the measurement values of a rotational angle measurement device 20 and a clinometer 23. These errors are produced between the parallel links.

While a beta measurement instrument 52 obtains an error beta generated in the rotational angle of an output node with respect to the reference plane based on the error information. Then a robot controller 42 controls a drive motor in order to erase those errors alpha and beta. Thus the interpolation is carried out at a high speed.

Abstract: PROBLEM TO BE SOLVED: To evade the wrong recognition of a white line and a preceding vehicle on a road as much as possible and also to improve the measurement accuracy for recognition of the white line by varying the detection range of the white line according to the distance between vehicles. SOLUTION: The distance L between vehicles is measured (S1) and compared with the maximum detection range Zmax (S2). The white line detection range Z is set at the range Zmax (S4), and the distance L is compared with the minimum detection range Zmin (S3). The range Z is set as the distance L (S5) and then set at the range Zmin (S6). The initial value Zs is set at the white line detection start position Zo for the distance Zs between the position Zo and a while line detection point (S8). The coordinate of an image is calculated for the distance Zs by the perspective change method (S9), and a white line is detected from the coordinate of the image (S10). The Zi is added to the distance Zs for calculation of the distance Zs between the next white line detection start position and the while line detection point (S11). The distance Zs is compared with the range Z (S12).  Then the procedure returns to S9 and S1 when Zs<Z and Zs>=Z are satisfied, respectively.
