CONTROL SYSTEM FOR VEHICLE

摘要

A control system for a vehicle includes an imaging device; a co-ECU to limit the travel speed of the vehicle; and an ECU to set the speed limit, that recognizes the speed limit value on a road while traveling, and sets the recognized speed limit value in the co-ECU. If the elapsed time since the speed limit value has been set reaches a predetermined time, the ECU estimates the speed limit value on the road while traveling, and if receiving a switch command, switches the speed limit value set in the co-ECU to the estimated speed limit value so as to avoid limiting the vehicle speed by a speed limit value that is different from the actual speed limit value on the road.

主权项

1. A control system for a vehicle, comprising:
an imaging unit configured to capture an image of a sign that represents a speed limit value on a road on which the vehicle is traveling; a recognition unit configured to obtain information about the image captured by the imaging unit, and to recognize the speed limit value; a setting unit configured to set the speed limit value recognized by the recognition unit; a limiter unit configured to limit a vehicle speed of the vehicle, based on the speed limit value set by the setting unit; a measurement unit configured to measure at least one of an elapsed time and a travel distance, since the speed limit value recognized by the recognition unit has been set by the setting unit; an estimation unit configured to estimate the speed limit value on the road on which the vehicle is traveling in at least one of a case where the elapsed time measured by the measurement unit has reached a predetermined time, and a case where the travel distance measured by the measurement unit has reached a predetermined distance; a display unit configured to display the speed limit value estimated by the estimation unit on a display device before switching the speed limit value set by the setting unit to the speed limit value estimated by the estimation unit; and a command determination unit configured, when the speed limit value estimated by the estimation unit is displayed on the display device, to determine whether a switching command to switch to the speed limit value estimated by the estimation unit has been input; wherein if the command determination unit determines that the switching command has been input, the speed limit value set by the setting unit is switched to the speed limit value estimated by the estimation unit.
