  • Publication number: 20170267286
    Abstract: A method of assisting a driver of a vehicle includes obtaining a feature of a road to be traveled by the vehicle with a sensor and/or a GPS system. A parameter is selected to assist a driver of the vehicle in driving a segment of the road based on the feature of the road. The parameter includes information on the location of a boundary along the road and a preferred trajectory to be driven along the road. A controller determines whether a current trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road. A feedback operation is provided to assist the driver in guiding the vehicle nearer to the preferred trajectory based on the selected parameter.

  • Patent number: 9649980
    Abstract: Captured images obtained beforehand by imaging ranges corresponding to peripheries of a vehicle, or processed images generated to correspond to the captured images are stored to be associated with stored road information of a preset area. A superimposed area having a clarity lower than a preset clarity threshold is set in a captured image of a periphery of the vehicle. A superimposition image is extracted among the stored images, the superimposition image being an image of a range corresponding to the captured image. A superimposed image is generated by superimposing an image in an area in the extracted superimposition image corresponding to the superimposed area on the captured mage. A video generated from the superimposed image is displayed at a position visible from a driver.

  • Patent number: 9457842
    Abstract: A parking mode selection apparatus selects one parking mode among from plural parking modes including at least a perpendicular parking or a parallel parking. The parking mode selection apparatus includes a steer angle detector that detects a steer angle of a steering wheel, an operation detector that detects, based on the steer angle detected by the steer angle detector, a predetermined operation in which the steering wheel is returned to a neutral position after rotated to a right or a left, and a parking mode selector. The parking mode selector selects, when the predetermined operation is detected by the operation detector, a parking mode that coincides with a steered direction to the right or the left of the steer angle detected by the steer angle detector and is associated with said steer angle.

  • Publication number: 20160090086
    Abstract: A method of assisting a driver of a vehicle includes identifying a road to be driven by the driver using a position determination unit. A parameter is selected to assist a driver of the vehicle in driving a segment of the road. The parameter includes information on the location of a boundary along the road and a preferred trajectory to be driven along the road. A controller determines whether a driven trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road. A feedback operation is provided while travelling the road to assist the driver in guiding the vehicle from the driven trajectory nearer to the preferred trajectory based on the selected parameter. The preferred trajectory is updated based on the driven trajectory of the vehicle along the road.
