DSC CONTROL OPERATION
id041800819200
• When the dynamic stability control (DSC)/roll stability control (RSC) hydraulic unit (HU)/control module (CM)
determines that the vehicle has a strong oversteer or understeer tendency, engine output is lowered and, at the
same time, it suppresses the yaw moment by affecting the braking of the front or rear wheels to inhibit the
oversteer or understeer tendency.
Oversteer Tendency Suppression
• When a large oversteer tendency is determined, braking is applied the outer front wheel according to the
degree of the tendency. As a result, a yaw moment is formed towards the outer side of the vehicle and the
oversteer tendency is suppressed.
Understeer Tendency Suppression
• When a large understeer tendency is determined, engine output is controlled and braking is applied to the inner
front wheel according to the degree of the tendency. As a result, a yaw moment is formed towards the inner
side of the vehicle and the understeer tendency is suppressed.
