An information display apparatus for vehicles for securely providing the driver with only information corresponding to the running condition, the information display apparatus comprising an information processor for receiving information detected by various sensors and monitors and for detecting the running condition of the vehicle, memory containing information on respective running conditions for display and degree of information importance being, and a display unit for displaying information in a display area or in an amount according to the degree of importance. The memory of the information display apparatus is used to read information corresponding to the detected running condition and the degree of information importance. The display area of speed information is increased when the vehicle is running straight and the display area of information about conditions behind the vehicle is increased when the vehicle is traveling in reverse.
A vehicle-mounted equipment control system having a power state detecting unit for detecting whether a power of vehicle-mounted equipment is ON or OFF, a vehicle state detecting unit for detecting whether a vehicle is running or at a standstill, a counting unit for performing a counting operation when the power state detecting unit detects a change of power from OFF to ON, and for performing a resetting operation when the vehicle state detecting unit detects a change of vehicle state from a running state to standstill state, and a control unit for regulating or deregulating the image display or the operation of the vehicle-mounted equipment based on a detected result of the vehicle state detecting unit and a counted value of the counting unit.
The invention relates to a method for displaying a perspective image and to a display device for at least one passenger of a motor vehicle. The air of the vehicle is to guarantee by simple means a high road safety that is substantially independent of the knowledge and skills of the driver. To this end, a method for displaying a perspective image (B) with one image element (4A to 4H) for at least one passenger of a motor vehicle is provided, said image (B) representing the view of the passenger. According to the inventive method, the image element (4A to 4H) is changed in at least one size depending on the forward travel way (F), on at least one operational parameter of the motor vehicle and/or on at least one parameter of an object (6) identified in the range of the travel way (F).
A navigation system includes an input device for inputting a destination, a current location detector for detecting current location of the vehicle, a camera for imaging an area to the rear of the vehicle, a route search program for searching for a route to the destination and a controller for providing guidance along the route determined by the route search. The controller controls the imaging by the camera according to route guidance information and determines whether a lane change is required in accordance with information obtained from the image. When it is determined that a lane change is required, the traffic situation in the vicinity surrounding the vehicle is recognized and guidance for the lane change is provided.
A navigation apparatus for appropriately providing a driver with necessary information without offering an excessive amount of information. When there are a plurality of information to be provided to a driver, the navigation apparatus selects information having a high priority in accordance with a predetermined priority order (PR or RK in FIG. 6) and offers the selected information to the driver in the selected order.
