Title:
ROAD SURFACE FRICTION COEFFICIENT DETECTOR
Document Type and Number:
Japanese Patent JP2001315633
Kind Code:
A
Abstract:
To provide a road surface friction coefficient detector capable of obtaining a μ value required for the control of a vehicle.
According to detected accelerator opening θa (step S1), target deceleration EBA(t) is computed (steps S3-S6). After imparting braking torque (step S7), the μ value is detected on the basis of a slip state and actual deceleration Gy(t) (step S8-S11).
