Abstract

A computer-implemented vehicle controller (VCON) is positioned in the passenger compartment of a vehicle on a test track. The VCON communicates with a base computer for receiving commands therefrom. In response, the VCON, which includes a servo controller and associated servos that are coupled to the controls of the vehicle, operates the controls of the vehicle to drive the vehicle around the test track.

2. The VCON of claim 1, wherein the vehicle includes a position antenna for generating a position signal, and the VCON further comprises:

a position circuit for receiving the position signal, the position circuit being electrically connected to the slave cpu for sending the position signal thereto for transmission of the position signal to the base computer.

3. The VCON of claim 2, comprising a shift servo, a brake servo, an accelerator servo, and a steering servo.

4. The VCON of claim 3, comprising a power up device (PUD) for receiving data from the vehicle, the PUD being electrically connected to the master cpu.

5. The VCON of claim 4, wherein the PUD includes:

a flight recorder electrically connected to a data bus of the vehicle for receiving data therefrom, the data being representative of at least engine rpm, vehicle speed; and

a decoder electrically connected to the flight recorder.

6. The VCON of claim 5, further comprising a select switch electrically connected to the decoder for enabling control of the vehicle by the VCON.

7. The VCON of claim 6, further comprising a manual input device electrically connected to the decoder, wherein the select switch can be moved to:
