Steering control device

A steering control device, comprising;

• a driver support torque computer which computes a driver support torque according to a driver torque,
• an automatic driver torque computer which computes an automatic driver torque according to road condition, and
• an additional driver torque computer which computes an additional driver torque according to the driver support torque and the automatic driver torque,
• wherein the additional driver torque computer receives an output from at least one of a first torque correction computer and a second torque correction computer;
• wherein the first torque correction computer includes:
• a weight computer which computes an increment of weight based on a magnitude of the driver torque, and accumulates the increment of weight to generate a weight,
• a clip value computer which computes an automatic driver torque clip value according to the weight, and
• a clip processor which clip processes the automatic driver torque with the automatic driver torque clip value, to limit an upper limit value and a lower limit value thereof, and outputs a clip processed automatic driver torque, to the additional driver torque computer and
• the second torque correction computer includes:
• a gain computer which computes an increment of gain according to the driver torque, and accumulates the increment of gain to generate a gain, and
• a gain processor which outputs an automatic driver torque multiplied by the gain, to the additional driver torque computer.
