  • Patent number: 11364897
    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.

  • Patent number: 11345338
    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.

  • Patent number: 11207479
    Abstract: A fan unit produces an airflow. A pressure difference generating member causes a pressure difference in the airflow. A sensor detects a pressure difference between the air pressure on the upstream side of the pressure difference generating member and the air pressure on the downstream side thereof. A straightening plate is provided between the fan unit and the pressure difference generating member, and straightens the airflow produced by the fan unit. A straightening plate comprises a first fin and a second fin which are arranged along the airflow, and a lattice-like third fin which is arranged on the downstream side of the first fin and the second fin, and through which the airflow through the first fin and the second fin passes.

  • Publication number: 20210300342
    Abstract: A parking assist system includes a control device. The control device continues an automatic parking process as a driver releases an operation on a brake pedal in a case where an obstacle is detected in a suspension area and an operation amount of the brake pedal has been equal to or more than a second threshold. The control device causes a brake device to stop a vehicle with a second brake force and suspends the automatic parking process in a case where the obstacle is detected in the suspension area and the operation amount of the brake pedal is less than the second threshold. The control device causes the brake device to stop the vehicle and cancels the automatic parking process in a case where the obstacle is detected in a cancellation area and the operation amount of the brake pedal is less than a first threshold.

  • 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: 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: 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.
