Filed: 1990-11-09
Abstract: PURPOSE:To maintain good accuracy of detecting a ground car speed all the time by designing a detector so as to increase the number of samples in the case a relatively large error is predicted to occur in the output signal of a receiver. CONSTITUTION:A ground car speed determination means 4 determines a ground car speed using a series of multiple sample car speeds among a multitude of sample car speeds determined by a sample car speed determination means 3.
