Title: Driving support method and driving support system
Inventor: IWAKI KEIYA
IPC: G08G1/0962
Filed: 2022-02-24
Abstract: To provide a technique capable of suppressing the display of an incorrect speed limit, deviated from the actual state, on a display device.SOLUTION: A driving support system applied to a vehicle reads a speed limit at a travel position of the vehicle out of map information in which speed limits are registered. The driving support system displays the speed limit read out of the map information. In a first zone in which a temporary speed limit is set, however, even if the speed limit registered in the map information is changed, the driving support system inhibits update of the speed limit to be displayed on the display device.SELECTED DRAWING: Figure 5
