IPC: G01S7/526
Filed: 1993-03-19
Abstract: PURPOSE:To reduce the error of a car ground speed due to the change in transmission frequency in a Dappler type car ground speed detection device including a smoothing means. CONSTITUTION:The reflection wave from a road surface of a wave transmitted from a transmitter 10 is received by a receiver 16. Transmission frequency is changed by a transmission frequency modification device 12 so that the reception sensitivity of the received wave increases. The reception wave is sent to a mixer 24 via an amplifier 18, etc., and is mixed with a transmission wave, thus obtaining Doppler frequency. The obtained Doppler frequency is processed by a Doppler frequency compensation program and a compensation condition modification program by a Doppler frequency processor 28 and is sent to a car ground speed processor 30 for performing car ground speed operation. The compensation condition modification program adds frequency modification content to the Doppler frequency after compensation when the transmission frequency is changed, thus rapidly changing the Doppler frequency according to the modification of the transmission frequency.

At this moment, the pressure increment due to the expansion of the oil in pocket 4 is absorbed by part 4a and with the temperature increase. Thus the pressure can be kept constant within pocket 4, ensuring the high-acuracy measurement of the temperature.

Filed: 1988-04-06
Abstract: PURPOSE:To remove vibration due to a sudden change in acceleration by generating a continuously smooth targeted speed even when a positional deviation at the time of starting movement or up to an object is small. CONSTITUTION:A main control part 1a is provided with a CPU, a ROM, a RAM, and a DMA controller and generates targeted position information and a servocontrol part 1b receives the information and commands the speed control of a moor 2. A PWM driving part 1c drives the motor 2 based on said command. At the time of receiving an increment/decrement constant sufficiently smaller than respective command values relating to a targeted position, a cycle speed, the number of times of increment/ decrement, and the number of repeats and a cycle speed command value, the main control part 1a adds the increment/decrement constant to the preceding targeted position to set up a new targeted value, finds out a deviation between the targeted value and a current position and reads out speed information based on a prescribed deceleration characteristic to repeatedly control the motor 2 only by the number of command. Thereafter, the main control part 1a finally stops the motor 2 after said repeats. In said constitution, the acceleration of the motor 2 can be directly changed by leading a trapezoidal cycle speed command value and the motor can be smoothly rotated.
