WHEEL-STATE ESTIMATION DEVICE AND VEHICLE CONTROL DEVICE
First Claim
1. A wheel-state estimation device which estimates a force or acceleration acting on a wheel provided in an automotive vehicle, comprising:
- a plurality of wheel side detection units respectively provided in a plurality of wheels of the vehicle, each wheel side detecting unit detecting a force or acceleration acting on a corresponding one of the wheels; and
an estimation unit estimating, when use of detection results of one of the wheels from one of the plurality of wheel side detection units is suspended, a force or acceleration acting on said one of the wheels with respect to the suspended use of the detection results, by using detection results of other wheels from other wheel side detection units.

Abstract
In a wheel-state estimation device which estimates a force or acceleration acting on a wheel provided in an automotive vehicle, a plurality of wheel side detection units are respectively provided in a plurality of wheels of the vehicle, each wheel side detecting unit detecting a force or acceleration acting on a corresponding one of the wheels. An estimation unit estimates, when use of detection results of one of the wheels from one of the plurality of wheel side detection units is suspended, a force or acceleration acting on the one of the wheels with respect to the suspended use of the detection results, by using detection results of other wheels from other wheel side detection units.
