  • Publication number: 20210107466
    Abstract: A parking assistance apparatus obtains a target travelling route including a forward section and a backward section and lets a vehicle move along the target travelling route such that the vehicle reaches a target parking position. The parking assistance apparatus execute a collision avoidance processing when an obstacle which is closer than a threshold distance is detected while the vehicle moves along the target travelling route. The distance between the vehicle and a specific region is kept to be larger than a clearance distance while the vehicle moves along the backward section such that the obstacle for the collision avoidance processing which cannot be detected while the vehicle moves along the forward section will not be found while the vehicle moves along the backward section. The specific region is determined on the basis of a detection region of a sensor device for detecting the obstacle and the threshold distance.

  • Publication number: 20210107465
    Abstract: A parking assist apparatus comprises an imaging apparatus and a controller configured to extract feature points from captured image where a region a driver desires to register a parking position therein is captured, and register the extracted feature points in association with the parking position, registering this position as registered parking position. When it is determined that a feature point(s) is detectable from captured image, the controller calculates the registered parking position by detecting the feature point(s), and performs parking assist control for parking the vehicle in the registered parking position.

  • Publication number: 20210107524
    Abstract: A vehicle parking assist apparatus acquires and registers first information on a parking lot from a camera image when a vehicle stops by the parking lot. The vehicle parking assist apparatus acquires and registers second information on the parking lot from the camera image when completing parking the vehicle in the parking lot by a parking assist control. The vehicle parking assist apparatus acquires the information on the parking lot as current parking lot information from the camera image when the vehicle stops by the parking lot after registering the first and second parking lot information and executes the parking assist control with realizing a relationship in position between the vehicle and the parking lot by comparing the current parking lot information with the registered parking lot information.

  • Publication number: 20210107458
    Abstract: A vehicle parking assist apparatus acquires a camera image when the vehicle stops by a non-determined parking lot and acquires feature points of a ground of an entrance of the non-determined parking lot as non-compared entrance feature points from the camera image. The vehicle parking assist apparatus determines whether the non-determined parking lot is a registered parking lot by comparing information on the non-compared entrance feature points with registered entrance feature point information. The vehicle parking assist apparatus executes a parking assist control with using the currently-acquired parking lot information and the registered parking lot information when the vehicle parking assist apparatus determines that the non-determined parking lot is the registered parking lot.

  • Publication number: 20210107467
    Abstract: A vehicle parking assist apparatus acquires a feature image from a registration image representing a parking lot to register the feature image as parking lot information. The registration image is an image that a camera takes when the vehicle parking assist apparatus receives a registration request for registering a parking area in that the vehicle is parked. The vehicle parking assist apparatus determines that the vehicle has reached the parking area specified by the parking lot information when an image part that has the same feature as the feature image is included in a post registration image. The vehicle parking assist apparatus specifies an object image being an image representing a object from the registration image when the object is present in the area corresponding to the registration image; and acquires the feature image based on the registration image from which the specified object image is excluded.

  • Patent number: 10930150
    Abstract: When an automatic parking registration method is selected, a vehicle control ECU performs a pre-registration automatic parking control and stores a position determined based on a position of a vehicle at a time point at which the vehicle is set to a stop state by the pre-registration automatic parking control as a registered parking position in a non-volatile memory. When an execution condition of a post-registration automatic parking control is satisfied, the vehicle control ECU performs the post-registration automatic parking control after setting a target parking position to registered parking position which has been stored in the non-volatile memory.

  • Publication number: 20180118219
    Abstract: A feedback server includes a processing circuitry configured to determine an actual driving performance of a driver in a manual driving mode and a projected driving performance if the vehicle had been operated in an autonomous driving mode, compare the driving performance in the manual driving mode and the autonomous driving mode, and transmit a feedback to the driver based on the comparison. The processing circuitry can be further configured to determine a driver state of the driver in the manual driving mode, determine environmental driving condition of the vehicle, and establish a baseline behavior of the driver as a function of the driver state and the environmental driving condition.

  • Patent number: 9643602
    Abstract: A parking support device 1 includes a calculation unit 17 that calculates a speed pattern, an acceleration recognition unit 13 that recognizes driver-requested acceleration, a parking support control unit 19 that performs parking support control in a target parking position based on the speed pattern, and a determination unit 18 that determines whether a host vehicle V can stop in the target parking position at a set deceleration. When the driver-requested acceleration is recognized during the control and exceeds acceleration of the speed pattern at the time of recognition, the parking support control unit 19 accelerates the host vehicle V at the driver-requested acceleration. When the determination unit 18 determines that the host vehicle V can stop in the target parking position at the set deceleration, the host vehicle V is decelerated at the set deceleration and is stopped in the target parking position regardless of the driver-requested acceleration.
