Abstract
A device and method for indicating the engine speed of a motor vehicle is provided. The engine speed in a motor vehicle is displayed, during a gear speed change via an engine speed signal, which is independent of the detected engine speed signal that is output as the engine speed signal, which is to be displayed, to the engine speed display module by way of an electronic transmission control module in the vehicle.
Claims12
A device for indicating an engine speed in a motor vehicle, comprising:
- a sensor for detecting an actual engine speed;
- at least one electronic module operatively configured to receive the actual engine speed, the electronic module providing a detected engine speed signal;
- an engine speed display module operatively coupled with the electronic module in order to display the detected engine speed signal;
- and
- an electronic transmission control module operatively configured to generate a gear change signal during a gear change, said gear change signal being detectable by at least one of the electronic module and the engine speed display module;
- and
- wherein during the gear change, the engine speed display module displays an engine speed based on an engine speed signal, which is independent of the detected engine speed signal.
A method for displaying engine speed via an electronic module, which processes a detected engine speed signal, and an engine speed display module, which receives from the electronic module the processed engine speed signal, the method comprising the acts of:
- outputting a gear change signal via an electronic transmission control module in the vehicle during a gear change;
- detecting the gear change signal by at least one of the engine speed display module and the electronic module;
- and
- displaying by the engine speed display module during the gear change an engine speed based on an engine speed signal which is independent of the detected engine speed signal.
A method for indicating engine speed in a motor vehicle during a gear change of the motor vehicle, the method comprising the acts of:
- detecting an actual engine speed;
- outputting an engine speed signal from an electronic transmission control module in the vehicle during a gear speed change;
- and
- displaying an engine speed based on the engine speed signal output from the electronic transmission control module at least during the gear speed change, wherein the engine speed signal is independent of the detected actual engine speed.
