  • Publication number: 20210291812
    Abstract: A movement path is regenerated within a movement capable region in accordance with an instruction to correct a movement path by a pointing unit, and the regenerated movement path is displayed on a display unit in a superimposed manner on a movement capable region for a user's own vehicle. As a result, without changing a parking space (position) in which a vehicle occupant desires to park, it is possible for parking to be performed along the desired movement path to the desired parking space.

  • Publication number: 20210291810
    Abstract: A steering motor generates a driving force based on a steering instruction from a travel control unit and applies a steering axial force to a rack shaft to thereby cause vehicle wheels to be steered. An action planning unit, through the travel control unit, initiates traveling at a starting position of parking on a movement path by suppressing the steering axial force to be less than a maximum driving force of the steering motor.

  • Publication number: 20210291811
    Abstract: An automated parking movement path is generated such that a vehicle speed and a steering angle are set so as to enable a full steering axial force to be applied within a range of being less than a maximum driving force which depends on the temperature of a steering motor. Consequently, a load on the steering motor is suppressed, and thus a rise in the temperature of a steering motor is suppressed within the movement path from a movement starting position to a movement ending position.

  • Publication number: 20210179057
    Abstract: An automated-parking control unit prevents a brake noise during braking, when causing a vehicle to start moving forward or backward. The automated-parking control unit includes: an environment recognizer to recognize environment of a vehicle; a behavior controller to execute behavior control inclusive of steering and acceleration/deceleration, based on recognized information; a brake hold instructor to suspend the vehicle with the behavior control and hold the suspension until receiving behavior-related operation by a driver; and a brake fluid pressure controller, when the vehicle is made to start moving forward or backward, to estimate a range having a brake noise and increase a change rate of a brake fluid pressure in a brake-noise range having a brake noise, as compared with that in a no-brake-noise range.

  • Publication number: 20210179083
    Abstract: A parking assist system for a vehicle includes a control device configured to control the vehicle to execute an automatic moving process for autonomously moving the vehicle from a current position to a target position. The control device is configured such that, in a case where a parking brake driving condition is satisfied when the control device stops the vehicle during movement to the target position in the automatic moving process and thereafter cancels the automatic moving process without permitting resumption of the movement of the vehicle, the control device switches a shift position of the shift device of the vehicle to a parking position and drives the parking brake device of the vehicle.

  • Publication number: 20210179078
    Abstract: A parking assist system includes: a display device configured to display a parking space candidate; and a control device configured to control a screen display of the display device, to set the parking space candidate selected by a user to a target parking space, to set a stop position where the vehicle should be stopped in the target parking space, and to execute a driving process to autonomously move the vehicle along a trajectory to the stop position. While executing the driving process, the control device causes the display device to display the trajectory and the stop position and determines whether the stop position is suitable based on external environment information. Upon determining that the stop position is not suitable, the control device corrects the stop position and causes the display device to display the stop position that has been corrected.

  • Publication number: 20200398822
    Abstract: A parking assist system includes: a control device configured to control an autonomous parking operation to move a vehicle autonomously to a prescribed target parking position; and a vehicle state detecting device configured to detect a state of the vehicle. During control of the parking operation, when the control device determines that the state of the vehicle detected by the vehicle state detecting device is a prohibition state in which the parking operation should be prohibited, the control device executes a prohibition deceleration process to decelerate the vehicle so as to stop the vehicle. The control device is configured to set an upper limit on deceleration of the vehicle in the prohibition deceleration process to be larger than an upper limit on deceleration of the vehicle in a stop operation to stop the vehicle at the target parking position.
