Abstract

The present invention comprises: an intention estimation unit (103) that estimates, with three or more levels of accuracy, the steering intention of steering being performed by a driver in order to change lanes; and an intervention degree determination unit (105) which, for higher accuracies of the steering intention estimated by the intention estimation unit (103), determines a higher value for the degree of intervention of a steering assistance system (10) mounted in a vehicle being driven by the driver. The degree of intervention becomes relatively low when the accuracy of the steering intention is relatively low. Accordingly, it is possible to prevent the steering assistance system from excessively intervening in steering and giving the driver an unnatural feeling of manipulation from a time point when the steering intention is unclear. The degree of intervention becomes relatively high when the accuracy of the steering intention is relatively high. Accordingly, when the steering intention becomes clear, the degree of intervention of the steering assistance system in the steering becomes high, and the steering assistance system can assist the steering of the driver.

Abstract

This steering control device is configured to execute a torque acquisition process, steering angle acquisition process, and determination process. In the torque acquisition process, the value of a torque variable is acquired. The torque variable indicates the drive torque, which is the torque for driving a steering mechanism. In the steering angle acquisition process, a steering angle variable is acquired. On the basis of the torque variable and the steering angle variable, which are used as input variables, the determination process determines that a fault leading to an increase in force required for steering increases has occurred, provided that the logical product of the torque gradient being equal to or greater than a predetermined value and the amount of increase in the absolute value of the drive torque exceeding a predetermined amount is true. The torque gradient is the ratio of the amount of increase in the absolute value of the drive torque to the absolute value of the amount of change in the steering angle indicated by the steering angle variable.

Abstract

A steering control device (1) has a processing circuit (1A) that controls a reaction force motor (12) and a turning motor (31). The processing circuit can select a steering control mode from a normal mode and a play mode. The normal mode is a mode that is selected when actually causing a vehicle to travel. The play mode is a mode that is selected when performing simulated traveling using the vehicle or when a vehicle is used to perform an operation of a simulated vehicle. When the play mode is selected as the steering control mode, the processing circuit causes the steering control mode to transition from the play mode to the normal mode when it is detected that the vehicle is traveling, or when a sign that the vehicle starts traveling is detected.

Abstract

A motor control device (11) is provided with a command value computation unit (31) and a disturbance observer unit (33). The command value computation unit computes a command value (T*ldld) acting on the mechanical device on the basis of the command value and rotation information (θ) regarding the motor and corrects the command value on the basis of the estimated disturbance. The disturbance observer unit includes an estimator (33A) that has a nominal plant (P^). The nominal plant is a model that simulates the mechanical device, and is constituted only by an inertia term from among an inertia term, a viscosity term, and a rigidity term. The estimator estimates the disturbance on the basis of the difference between output of the mechanical device in response to the command value and output of the nominal plant in response to the command value.

Abstract

This steering control device is configured to execute a steering angle acquisition process, a target turning equivalent angle setting process, a turning operation process, a determination process, and a gradual change process. The target turning equivalent angle setting process is a process for setting a target turning equivalent angle according to a selected driving mode among a plurality of driving modes on the basis of a steering angle as an input variable. The plurality of driving modes are set such that the gear ratio, which is the ratio of the target turning equivalent angle to the steering angle, can be different in each of the driving modes. The determination process is a process for assessing, on the basis of whether a vehicle is in a stopped state or a traveling state, whether or not to execute the gradual change process when a request to switch the driving mode occurs. The gradual change process is a process for gradually bringing the target turning equivalent angle corresponding to the driving mode before switching closer to the target turning equivalent angle corresponding to the driving mode after switching.
