<P>PROBLEM TO BE SOLVED: To provide a device for estimating longitudinal acceleration that can improve the accuracy of estimating longitudinal acceleration or a road friction coefficient of a vehicle or a road condition. <P>SOLUTION: The longitudinal acceleration estimation device 22 includes an acceleration estimation unit 110 for calculating an estimation value of the longitudinal acceleration of a vehicle 10 from a difference between a detection value of a longitudinal acceleration sensor 42 when the vehicle is accelerated or decelerated and a subsequent detection value of the longitudinal acceleration sensor 42. <P>COPYRIGHT: (C)2013,JPO&INPIT |
