車速検出装置
Document Type and Number:
Japanese Patent JP7417566
Kind Code:
B2
Abstract:
To calculate the speed of a vehicle accurately in real time.SOLUTION: A wheel rate detector 12 includes: a wheel rate sensor 44 using a pulsar ring rotatably and integrally attached to a front wheel; a pulse-vehicle rate converter 62 for generating a raw vehicle rate signal Vp from a pulse signal Sp detected by the wheel rate sensor; and a vehicle rate signal calculation unit 64 for correcting the raw vehicle rate signal in consideration of information related to the eccentricity to the vehicle axis of the pulsar ring and calculating a vehicle rate signal V with less eccentricity noise caused by eccentricity.SELECTED DRAWING: Figure 4
