Benefits of technology

The invention provides an improved way to indicate if a car is moving correctly by giving them a certain amount of space between their wheels. This helps prevent errors caused by uneven road surfaces or other factors like tires on bumpy roads.

Problems solved by technology

The technical problem addressed in this patent text relates to improving the accuracy of detecting pitch and roll movements when vehicles travel over uneven surfaces or under heavy traffic conditions.

Embodiment Construction

[0021]Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

[0022]Referring initially to FIG. 1, a passenger compartment 10 of a vehicle 12 employing an embodiment of the present invention is illustrated. The vehicle 12 can be, for example, a truck, an SUV, an automobile or any other suitable type of vehicle. The passenger compartment 10 includes an instrument panel 14 which, in this example, has a display 16, which is typically referred to as a primary or secondary display, and a meter cluster 18. Typically, the display 16 includes features for a navigation display and / or an audio system display. On the other hand, as shown in more detail in FIG. 2, the meter cluster 18 generally includes meters 20, such a

Abstract

A vehicle orientation indicator comprises a sensor and a controller. The sensor is configured to sense a gravitational force component imposed on a vehicle. The controller is configured to determine an orientation of the vehicle with respect to a fixed plane based on the sensed gravitational force component and control an indicator device to provide a representation of the orientation of the vehicle. The controller is further configured to control the indicator device to update the representation of the orientation of the vehicle based on a change in the sensed gravitational force component as sensed by the sensor while a movement condition of the vehicle meets a prescribed condition, and to control the indicator device to refrain from updating the representation of the orientation of the vehicle while the movement condition fails to meet the prescribed condition.
