  • Publication number: 20150375740
    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.

  • Publication number: 20150367845
    Abstract: A parking assist apparatus that causes a vehicle to be parked in a target parking position generates a traveling route of a vehicle M from a parking travel start position P0 to a target parking position P2 (S12); generates a plurality of speed patterns having different speeds when the vehicle travels on the traveling route (S14); selects a target speed pattern from the plurality of speed patterns based on information of an object around the traveling route (S18); and controls the traveling of the vehicle M based on the target speed pattern (S24).

  • Patent number: 8958929
    Abstract: In a vehicle control apparatus which performs a remote operation of a vehicle using a remote control, a remote operation of the vehicle which is not intended by a driver is prevented. When traveling control of a vehicle is performed through a remote operation from a remote control 3, a stop position of a vehicle 2 is set by a stop position setting device 9, and a movement course of the vehicle 2 is calculated by the vehicle course calculation device 10. In addition, the vehicle 2 is moved along the calculated movement course in response to a driving operation from the remote control 3, but if a driving operation from inside of the vehicle and a driving operation from the remote control 3 come into conflict, the driving operation from the remote control 3 is canceled, and the driving operation from inside of the vehicle is prioritized.

  • Patent number: 8958986
    Abstract: A parking assistance apparatus includes a display unit that displays an image of a scene behind a host vehicle. At least when the host vehicle moves forward or when the host vehicle is stopped, the display unit displays an indication including a plurality of kinds of trajectories along which the host vehicle is able to back up from a point at which the host vehicle is currently positioned, in a manner such that the indication is superimposed on the image of the scene behind the host vehicle.

  • Publication number: 20140244073
    Abstract: In a vehicle including an automatic steering means enabling the vehicle to move automatically by receiving an instruction signal for a remote operation from a transmitter outside of the vehicle, the vehicle enables correspondence to an ambient condition change when parking-out. When an automatic steering unit automatically performs parking-out by receiving an instruction from a transmitter, obstacle conditions around the vehicle (particularly, around a door) obtained by a surrounding object sensor are detected, and it is determined whether a sufficient space is ensured for a passenger's getting on/off through a door to automatically move a vehicle to a place where getting on/off is easy.

  • Publication number: 20140232538
    Abstract: In device 1 including rear view wide angle camera 11, and ECU 20 and display 30 displaying rearward image captured by the camera 11, display control section 25 of the ECU 20 and the display 30 divides the image into right and left rear lateral screens 204 and central rearward screen 202 for display, driver can determine which place is displayed. The section 25 and the display 30 do not display the same image on the screens 204, 202, the driver can understand the distance between object in the image and host vehicle 100. The section 25 performs distortion correction of correcting distortion of the image displayed on the screens 204, the driver can see the image viewable due to the distortion correction. The section 25 forms the screens 204 in shape based on the distortion correction, the driver can understand an approaching position of the object in the image.

  • Publication number: 20140225723
    Abstract: In a driving support display device 1 that includes a rear view wide angle camera 11, and an ECU 20 and a display 30 that display a rearward image captured by the rear view wide angle camera 11, a display control section 25 of the ECU 20 and the display 30 is capable of displaying a moving object approaching detection frame 210 that supports driving of a driver of a host vehicle 100 and a pedestrian detection frame 212 while dividing the rearward image into plural screens for display, and changes the number of the screens to be displayed between when the moving object approaching detection frame 210 is displayed and when the moving object approaching detection frame 210 is not displayed. Thus, the driver can easily recognize operation and non-operation of a system that displays the moving object approaching detection frame 210.
