Title:
STEERING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3229074
Kind Code:
B2
Abstract:
PURPOSE: To reduce the capacity of a CPU by suppressing the change of the behavior of a vehicle by the turning behavior suppressing torque which is obtained by multiply ing the vehicle behavior detection value by the suppressing coefficient and the damping torque which is obtained by multiplying the steering angular speed by the damping coefficient and setting both the coefficients in proportion.
CONSTITUTION: As for a control unit 20 for controlling an electric motor 10 for applying a steering assisting force to a steered wheel, the target steering torque is obtained on the basis of the lateral accelerating speed and the yaw rate by a motor driven power steering control means 22. Further, the steering angular speed and the yaw rate difference are calculated by an active steering reaction force calculating means 23, and the steering reaction force is determined and the control signal which is obtained by multiplying the steering reaction force by the limitter is outputted, and added with the target steering torque. The additional value is converted to the target electric current value by an output electric current determining means 24 and outputted to the electric motor 10. In this case, the transmission function up to the generation of the yaw rate on a vehicle from the external turbulence input is obtained by using the control coefficient and the damping coefficient which are in a proportional relation.
