<p>PURPOSE:To improve the steering feeling by installing a manual adjusting circuit which varies and adjusts the motor-output instruction value corresponding to the steering torque in plural stages or steplessly, thus permitting a driver to arbitrarily set the steering auxiliary force optimum for himself. CONSTITUTION:A torque sensor 1 detects the steering torque in steering operation, and a motor-output instruction circuit 2 determines the motor-output instruction value corresponding to the steering torque value signal. In this case, a manual adjusting circuit 3 which readjusts the motor-output instruction value of the circuit 2 in plural stages or steplessly by the operation by a driver is installed. Said circuit 3 is constituted of, for example, multiplication circuit, and a motor driving part 4 controls a motor 5 so that the output of the value obtained by multiplying the motor-output instruction value of the circuit 2 by a certain factor by selecting and adjusting the factor to be multiplied. Therefore, the driver can arbitrarily set the steering auxiliary force optimum for himself.</p> |
