Abstract
A system (,) and method for automatically monitoring and/or controlling the actual speed of a vehicle (,) relative to the legal speed limit of the geographic area the vehicle is located in. A wireless transmission (,) containing location or legal speed limit information is received from a transmission source (,). If location information is obtained, database (,) is queried to obtain legal speed limit information for the physical location of the vehicle. The legal speed limit is stored into a memory space (,). Alternatively, the legal speed limit is used to control the actual speed of the vehicle. In a monitor mode, the system (,) compares the actual speed of the vehicle to the legal speed limit with a processor (,), and the relative information may be communicated to the driver. In an offset mode, the system (,) controls the actual speed of the vehicle to an offset amount relative to the legal speed limit, where the offset amount is set by the driver of the vehicle. The transmission source (,) may be a GPS-compatible satellite network (,) or a transmitter (,) on a traffic sign (,).
