Abstract

PURPOSE:To prevent steering force from its rapid change, when a vehicle is in running, by deciding a car speed signal to be abnormal through an engine speed and outputting fixed power to a solenoid control valve when the car speed signal is abnormal from this decision result. CONSTITUTION:An electronic control unit 30, which provides constitutional elements of a CPU31, ROM32 and a RAM33 connecting a solenoid 34 of a solenoid control valve 23 to the CPU31 through a solenoid circuit, controls an electric current applied by this CPU31. Constituting a car speed sensor 35 of an output shaft speed meter connected to an output shaft 40 of a transmission 39, an engine speed meter 36 is connected to a crankshaft of an engine 37. The ROM32 stores in memory a V-IM map showing the characteristic of an output current IM for a car speed and a fixed current IF, correction current DELTAI and steering torque control program controlling a current in the solenoid control valve 23 when a car speed signal is abnormal.
