Abstract
An information presentation system for a vehicle is provided. The vehicle comprises a transmission operable in a plurality of gear states. The system comprises a sensor adapted to detect a gear state of the transmission, an electronic control system adapted to operate the transmission and to detect a gear state of the transmission, and a display device coupled to the sensor and to the electronic control system. The display device is adapted to receive a first signal indicating the gear state of the transmission, to receive a second signal indicating the gear state of the transmission, and to adjust an arrangement of visual elements in a manner influenced by the first and second signals.
Claims20
An information presentation system for a vehicle, the vehicle comprising a transmission operable in a plurality of gear states, and the system comprising:
- a sensor adapted to detect an actual gear state of the transmission;
- an electronic control system adapted to operate the transmission and to detect a commanded gear state of the transmission;
- and
- a display device coupled to the sensor and to the electronic control system, the display device adapted to:
- receive a first signal indicating the actual gear state of the transmission;
- receive a second signal indicating the commanded gear state of the transmission;
- and
- adjust an arrangement of visual elements based on whether the first and second signals indicate that the commanded gear state is different from the actual gear state.
A display device for a vehicle, the vehicle comprising a transmission having a plurality of gear states, the display device adapted to:
- receive a first signal that is indicative of a commanded gear state of the transmission;
- receive a second signal that is indicative of an actual gear state of the transmission;
- display a first visual image comprising a first foreground portion and a first background portion when the first and second signals indicate the same gear state of the transmission;
- and
- display a second visual image comprising a second foreground portion and a second background portion when the first and second signals indicate different gear states of the transmission.
A method of displaying transmission gear state information to an operator of a vehicle, the transmission operable in a plurality of gear states, and the method comprising:
- receiving a first signal from an electronic control system coupled to the transmission, the first signal conveying information indicating a gear state of the transmission;
- determining a gear state of the transmission with a sensor, the sensor operating independently of the electronic control system;
- receiving a second signal from a sensor coupled to the transmission, the second signal conveying information indicating a gear state of the transmission;
- comparing the gear state indicated by the first signal to the gear state indicated by the second signal;
- and
- presenting a first visual image to the operator of the vehicle in response to determining that the first and second signals convey information indicating different gear states.
