Abstract

A vehicle display apparatus for displaying vehicle information has a pulse generating device. This pulse generating device includes at least: control means comprising a control part and an output part; and an output terminal (output means). The control part receives data of number of wheel rotations (wheel speed data) from an ABS unit mounted on the vehicle via a multiplex communication line, and generates, based on the received data of number of wheel rotations, a pulse signal that can be used for a retrofitted navigation unit (information display device) that is mounted on the vehicle later. The pulse signal generated by the control means is outputted from the output terminal through a wire member to the navigation unit.

Claims

1. A pulse generating device comprising:

control means for receiving vehicle speed information or wheel speed information via a multiplex communication line from a control device mounted on a vehicle, and for generating, based on said vehicle speed information or said wheel speed information, a predetermined pulse signal that can be used for an information display device mounted on said vehicle; and

output means for outputting said pulse signal generated by said control means, to said information display device.

2. A pulse generating device according to claim 1,

wherein said control means and said output means belong to a vehicle display apparatus for displaying the running information of said vehicle.

3. A pulse generating device according to claim 1 or 2,

wherein said control means outputs said pulse signal according to the running state of said vehicle.

4. A pulse generating device according to claim 1,

wherein said information display device is a navigation unit.

5. A vehicle display apparatus for displaying vehicle information, including a pulse generating device comprising:

at least control means for receiving vehicle speed information or wheel speed information via a multiplex communication line from a control device mounted on a vehicle, and for generating, based on said vehicle speed information or said wheel speed information, a predetermined pulse signal that can be used for an information display device mounted on said vehicle; and

output means for outputting said pulse signal generated by said control means, to said information display device.

6. A vehicle display apparatus according to claim 5,

wherein said control means outputs said pulse signal according to the running state of said vehicle.

7. A vehicle display apparatus according to claim 5,

wherein said information display device is a navigation unit.
