摘要： To provide a toe angle changing control ECU for controlling a toe angle of wheels of a vehicle. The toe angle changing control ECU includes: a straight traveling state judging section (41) for judging whether or not the vehicle is in a straight traveling state within a predetermined time period based on detection results (a vehicle speed, a steering torque, a yaw rate, and a lateral acceleration) of the traveling condition of the vehicle; a memory (44) for storing the toe angle of the wheels while the vehicle is in the straight traveling state; and a toe angle setting section (43) for setting the wheels to the toe angle stored in the memory (44) when the straight traveling state judging section (41) judges that the vehicle is in the straight traveling state. While the vehicle is in the straight traveling state, the wheels are set to a toe angle at which the wheels are substantially parallel to the longitudinal direction of the vehicle, and the rolling resistance of the wheels becomes minimum theoretically. Thus, the fuel consumption can be improved.

摘要： Generally, the toe angle target speed limiting unit (84A) adds a toe angle target value αT2P subjected to the primary delay to the result of a min-max processing the tracking error ΔαT1A by an adder (58A) to output it as a toe angle target value αT2A to a target current calculating unit (86). However, in this toe angle target speed limiting unit (84A), a switching control (steering direction change control) for generating a maximum value ΔαTmax as the toe angle target change quantity ΔαT2 and a hold control are made when a neutral position of the toe angle target value αT2A which is prior to the toe angle command value αT1 which is reached.

摘要： A steering controller for an electric power steering device 110 includes a base signal computing part 51 for computing a base signal DT in accordance with at least the steering torque; a damper compensation signal computing part 52 for computing a damper compensation signal in accordance with an angular velocity of an electric motor 4 or a speed of steering wheel turn; and an inertia compensation signal computing part 53 for compensating inertia and viscosity in the steering unit. The electric motor is driven by a target signal IM1 obtained by compensating the base signal with a damper compensation signal and an inertia compensation signal, to provide a steering auxiliary force. The target signal of the auxiliary torque is compensated so that a difference between a reference self-aligning torque of front wheel in a front wheel steering vehicle and a self-aligning torque of front wheel in an all-wheel steering vehicle is provided to a driver as a responsive feeling from the steering torque.

摘要： The main calculation section (37a) of a toe angle alteration control ECU (37) in a vehicle control system receives target toe angles αTL and αTR from a steering control ECU (130) and controls a motor (31L) for changing the toe angles of a left rear wheel and a motor (31R) for changing the toe angle of a right rear wheel independently. Stroke sensors (38L, 38R) detect actual toe angles αL and αR and inputs to the judging portion (85) of actuations of the sub calculation section (37c). In accordance with a pre-stored judgment table (85a), the judging portion (85) of actuations calculates an allowable actuation range, which is a combination of the toe angles αL and αR of the left-and-right rear wheels depending on vehicle speed VS, and judges whether the actuation of the motor (31L, 31R) is suitable for the turning of a vehicle or not depending on whether the actual toe angles αL and αR is within the allowable actuation range or not.
