VEHICLE BODY SPEED ESTIMATION DEVICE, ESTIMATION METHOD FOR VEHICLE BODY SPEED AND BRAKING/DRIVE FORCE CONTROL UNIT

摘要

PROBLEM TO BE SOLVED: To provide a vehicle body speed estimation device capable of accurately estimating vehicle body speed even if a braking force generation unit includes one or more wheels having secular changes and abnormality.;SOLUTION: This vehicle body speed estimation device includes vehicle body speed estimation means 41d for estimating the vehicle body speed of a vehicle at which the motor torque of at least one of motors 31FL, 31FR, 31RL, 31RR can be independently assigned to at least one or more wheels 10FL, 10FR, 10RL, 10RR using information on the wheels. Further, the vehicle body speed estimation means 41d is configured so as to estimate the vehicle body speed upon controlling an ABS through the only use of the information on the wheels on which motor regenerative torque acts.;COPYRIGHT: (C)2008,JPO&INPIT
