Abstract
A vehicle display system which keeps a driver from inputting data into the system while driving a vehicle, but which permits a person in the front passenger seat to perform the data input operations. A main ECU inhibits data input operations, such as map retrieval, destination setting, and telephone number input operations, when it determines that the driver is driving the vehicle, i.e., when the vehicle is moving. However, when the driver grips the steering wheel and thereby depresses drive enforcement releasing switches located on the vehicle steering wheel, the main ECU releases the drive enforcement state, thereby enabling passengers other than the driver to perform data input operations.
