Onboard controller system
First Claim
1. An onboard controller system for a vehicle, comprising:
- a. TPS sensor means for receiving a genuine TPS signal from a throttle position sensor, the genuine TPS signal destined for an engine controller;
b. TPS spoof means for generating a spoofed TPS signal;
c. intercept means for intercepting the TPS signal;
d. TPS sender means for sending the spoofed TPS signal or the genuine TPS signal to the engine controller; and
e. a controller for selectively determining whether the TPS sender means sends the genuine TPS signal or the spoofed TPS signal based on the comparison of a vehicle parameter to a threshold parameter.

Abstract
A system and method for safely slowing or controlling a vehicle'"'"'s speed or engine speed by selectively replacing a genuine engine control signal with a spoofed engine control signal to slow or control the vehicle. The operator is allowed control of the vehicle (e.g. genuine engine control signal) if the speed is below a threshold speed and the operator is denied control of the vehicle (e.g. spoofed engine control signal) if the speed is above the threshold speed; similarly, a maximum idle engine speed and time to idle before shut-down is enforced by selectively replacing a genuine engine control signal with a spoofed engine control signal, responsive to a set threshold for each. The threshold is set over the air (OTA).
