Abstract: A steering control device that can set and cancel an automatic driving mode includes a steering control unit, a cancellation instruction detection unit, a stop detection unit, and a steering angle reduction unit. The steering control unit controls a steering angle in the automatic driving mode so that a vehicle travels along an intended route. The cancellation instruction detection unit detects a cancellation instruction to cancel the automatic driving mode. The stop detection unit detects a stop of the vehicle. The steering angle reduction unit reduces the steering angle set by the steering control unit, if the cancellation instruction detection unit detects the cancellation instruction and the stop detection unit detects the stop of the vehicle.

Abstract: An apparatus for performing driving aid control to cause a travel trajectory of a mobile object to follow a setpoint trajectory by transmitting a control command value to a yaw moment controller capable of controlling a yaw moment of the mobile object. In the apparatus, a first control command value calculator is configured to calculate a first control command value used to calculate the control command value. A straight-driving stabilizing compensator is configured to, when the mobile object is driving straight, calculate a first control command compensation value by decreasing the first control command value. A second control command value calculator is configured to calculate a second control command value used to calculate the control command value. A third control command value calculator is configured to calculate a final control command value based on the first control command compensation value and the second control command value.

Abstract: An apparatus for performing driving aid control to cause a travel trajectory of a mobile object to follow a setpoint trajectory by transmitting a control command value to a yaw moment controller. In the apparatus, a setpoint trajectory setter sets the setpoint trajectory of the mobile object. A first control command value calculator calculates a first control command value by performing target-position following control to cause a position of the mobile object to follow a future target position of the mobile object set on the setpoint trajectory. A second control command value calculator calculates a second control command value by performing setpoint-trajectory following control based on a current lateral error that is a lateral error between a current position of the mobile object and the setpoint trajectory. A third control command value calculator calculates the control command value based on the first control command value and the second control command value.

Abstract: An apparatus for performing driving aid control to cause a travel trajectory of a mobile object to follow a setpoint trajectory (La) by transmitting a control command value (?) to a yaw moment controller capable of controlling a yaw moment of the mobile object. In the apparatus, a setpoint trajectory setter is configured to set the setpoint trajectory (La) of the mobile object. A control command value calculator is configured to calculate the control command value (?) based on an integrated value (?I) of a lateral error that is an error between a position of the mobile object and the setpoint trajectory. The control command value calculator is further configured to decrease the integrated value (?I) with decreasing a curvature (?) of a road on which the mobile object is traveling.
