摘要： In a material handling vehicle such as an electric forklift, a depression amount of an accelerator pedal (26) that provides an instruction on a control amount of a drive motor (9) for driving a drive wheel (5) is detected. When the depression amount of the accelerator pedal (25) is equal to or larger than a predetermined value and a forward-backward switching signal that indicates that a shift lever (24) is operated is received, a drive current for a steered system motor (19) is set to a value smaller than a normal drive current within a predetermined time period (T) that starts upon reception of the forward-backward switching signal.

摘要： A motor vehicle steering system steers vehicle wheels (4) in response to the operation of an operation member (1, 61) for steering a vehicle. The system includes a rutted road judging unit (34, 83) which judges whether the vehicle is driving on a rutted road or not, and a steering enhancement control unit (31, S10, 32, 51, 84) which enhances steering of vehicle wheels (4) in response to operation of the operation member (1, 61) when the rutted road judging unit (34, 83) judges that the vehicle is driving on a rutted road than when the rutted road judging unit (34, 83) judges that the vehicle is not driving on a rutted road.

摘要： In a vehicle steering system, when a sensor malfunction determination unit (57) detects a malfunction of a rotation angle sensor (21), the sensor malfunction determination unit (57) changes a control mode from a first control mode to a second control mode. In the second control mode, an actual rotor angle (mechanical angle) (θ SM ) of a steered system motor (3) is computed on the basis of a second rotor angle (electric angle) (θ SE2 ) estimated by a rotation angle estimation unit (55). Then, feedback control is executed such that the actual rotor angle (θ SM ) converges to a target rotor angle (θ SM1 *) that is obtained by superimposing a rotation maintaining command signal on a target rotor angle (θ SM *) computed by a target rotor angle computation unit (41).

摘要： A steering angle detecting unit (13), a reaction force actuator (15) that applies steering reaction force to a steering member (10), a yaw angle detecting unit (33) that detects a yaw angle of a vehicle body, and a reaction force actuator control unit (16) that sets the steering reaction force as a function of a steering angle and that controls the reaction force actuator (15) such that the reaction force actuator (15) generates the set steering reaction force, are provided. The reaction force actuator control unit (16) computes a turning angle of the vehicle body on the basis of a change in the yaw angle of the vehicle body, detected by the yaw angle detecting unit (33). When the computed turning angle is larger than or equal to a reference angle, the steering reaction force applied to the steering member is increased.
