Patent number: 11260856Abstract: An information display device includes a surrounding environment detector, a vehicle information acquirer, a predictor, an avoidance path provider, and an information display. The surrounding environment detector detects position relevant information related to a position of at least a surrounding object in a surrounding environment of a vehicle. The vehicle information acquirer detects vehicle information including a speed and a steering direction of the vehicle. The predictor predicts a contact of the vehicle with the surrounding object, based on the position relevant information and the vehicle information. When the predictor has predicted that there is a possibility of the contact of the vehicle with the surrounding object, the avoidance path provider assumes an avoidance path for avoiding the contact, based on the position relevant information and the vehicle information. The information display displays the avoidance path.Type: GrantFiled: September 5, 2019Date of Patent: March 1, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Daisuke Tokunaga, Nobuyuki Nakano, Toshiya Mori
