Abstract:
A vehicle yaw stability control method and a vehicle yaw stability control apparatus are provided. The yaw rate {dot over (ψ)} of the vehicle is measured. A first reference yaw rate {dot over (ψ)}ref is set. A difference yaw rate Δ{dot over (ψ)} is set. Stabilizing braking intervention is triggered when a value of the difference yaw rate Δ{dot over (ψ)} exceeds limits defined by difference yaw rate threshold values Δ{dot over (ψ)}min, Δ{dot over (ψ)}max. Information regarding the shape of the road ahead of the vehicle is acquired. The reliability of the driver steering input δ is evaluated upon stabilizing braking intervention being triggered. In case the driver steering input δ is deemed unreliable a replacement reference yaw rate {dot over (ψ)}refroad is set based on the acquired road shape and a replacement difference yaw rate Δ{dot over (ψ)}road is set whereupon stabilizing braking intervention is performed based on the replacement difference yaw rate Δ{dot over (ψ)}road.
