Onboard controller system
First Claim
1. A method for interfering with the operation of a vehicle comprising the steps of:
- a. determining the vehicle speed;
b. selecting a threshold speed; and
c. controlling the vehicle by allowing operator control if the vehicle speed is less than the threshold speed and interfering with operator control if the vehicle speed is greater than the threshold speed.wherein the vehicle speed is reduced to the threshold speed.

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).

6. 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. - View Dependent Claims (7, 8)
