Display device and display system
First Claim
1. A display device comprising:
- a display provided inside a cabin of a vehicle;
a position detector provided in the vehicle, the position detector being configured to detect a position of the vehicle;
a storage device provided in the vehicle, the storage device being configured to store map information;
a vehicle speed detector provided in the vehicle, the vehicle speed detector being configured to detect a vehicle speed of the vehicle;
a steering angle detector provided in the vehicle, the steering angle detector being configured to detect a steering angle of the vehicle; and
an electronic control unit provided in the vehicle, the electronic control unit being configured to;
control the display such that a map view is shown on the display on a basis of the map information;
control the display such that an image indicating the position of the vehicle, detected by the position detector, is superimposed on the map view shown on the display;
acquire information about a traveling status of the vehicle;
determine whether a user of the vehicle is getting lost on a basis of the information about the traveling status of the vehicle and the map information; and
when the electronic control unit determines that the user is getting lost, control the display such that a scale of the map view shown on the display is set to a predetermined value or larger;
wherein the electronic control unit is configured to;
acquire the position, vehicle speed and steering angle of the vehicle from the position detector, the vehicle speed detector and the steering angle detector as the information about the traveling status of the vehicle;
identify a road on which the vehicle is traveling and a width of the road on a basis of the position of the vehicle and the map information; and
when the width of the road is smaller than a predetermined width, when the vehicle speed of the vehicle is lower than or equal to a predetermined speed lower than a regulation speed of the road and when the steering angle of the vehicle indicates that the vehicle was about to enter a one-way road in a reverse direction and subsequently returned to a straight-ahead traveling state, determine that the user is getting lost.
