Understeer suppressing apparatus for vehicle
An understeer suppressing apparatus for a vehicle includes an electric power steering device S for suppressing steering when the vehicle is in the understeer state, an alarm device A for informing a driver that the vehicle is in the understeer state, and a braking force distribution device B for generating moment of the vehicle by applying braking forces different from each other to the left and right wheels. As the degree of understeer is increased, the electric power steering device S, the alarm device A, and the braking force distribution device B are operated in this order.
1. A method of suppressing understeer of a vehicle, comprising the steps of:
suppressing front wheel steering with a steering reaction force device when the vehicle is in an understeer state;
informing with an alarm device that the vehicle is in the understeer state; and
applying braking forces with a braking force distribution device to at least one of a left and right wheel of the vehicle,
wherein as the amount of understeer is increased, the steering reaction force device, the alarm device, and the braking force distribution device are operated in this order.
2. The method of suppressing understeer of claim 1 , wherein during the step of informing, the steering reaction force device is continuously operated.
3. The method of suppressing understeer of claim 1 , wherein during the step of applying brake forces, the steering reaction force device and the alarm device are continuously operated.
