VEHICLE-CENTER-OF-GRAVITY CONDITION DETERMINING APPARATUS AND VEHICLE BEHAVIOR CONTROL SYSTEM

摘要

A vehicle-center-of-gravity condition determining apparatus includes: a rear wheel brake pressure change unit; a front wheel brake pressure detector; a rear wheel brake pressure detector; a rear wheel axle load estimating unit configured to estimate a rear wheel axle load based on a relationship between front and rear brake pressures detected during braking and a rear wheel axle load property of the rear wheel brake pressure change unit; and a vehicle-center-of-gravity condition determiner configured to determine a center of gravity condition of a vehicle in a vehicle width direction based on the estimated rear wheel axle load. The rear wheel axle load estimating unit is configured to estimate each of the rear wheel axle loads in a case where braking is performed in a state of at least two of during straight running, during right turning, and during left turning.

1. A vehicle-center-of-gravity condition determining apparatus, comprising:
a rear wheel brake pressure change unit configured to change rear wheel brake pressure according to a rear wheel axle load; a front wheel brake pressure detector configured to detect brake pressure of a front wheel; a rear wheel brake pressure detector configured to detect brake pressure of the rear wheel at a downstream side with respect to the rear wheel brake pressure change unit; a rear wheel axle load estimating unit configured to estimate a rear wheel axle load based on a relationship between front and rear brake pressures detected during braking and a rear wheel axle load property of the rear wheel brake pressure change unit; and a vehicle-center-of-gravity condition determiner configured to determine a center of gravity condition of a vehicle in a vehicle width direction based on the estimated rear wheel axle load, wherein the rear wheel axle load estimating unit is configured to estimate each of the rear wheel axle loads in a case where braking is performed in a state of at least two of during straight running, during right turning, and during left turning.
