Techniques for fault injection testing are described herein. The techniques may include receiving, at a computing device, an indication to simulate a fault associated with a component of a vehicle. The computing device may be coupled to the component via a control line that includes a relay or switch component that, when activated, causes the component to simulate the fault. The computing device may also receive data indicative of a vehicle response, such as a measured trajectory of the vehicle in response to the fault, whether a backup system of the vehicle performed correctly in response to the fault, whether the vehicle responded to the fault within a threshold period of time, and the like. The computing device may determine a difference between the vehicle response and an intended response of the vehicle relative to a threshold difference.

Autonomous vehicle fault injection testing

Aspects of the invention relate to a method comprising: determining an output torque at a wheel of a vehicle mounted to a test apparatus comprising an external motor, the output torque being in response to a command; determining a correction factor based on the output torque and at least one coefficient associated with a reaction of a component of the vehicle and/or of the test apparatus to an applied torque at the vehicle; and controlling the external motor to apply the correction factor to the wheel of the vehicle.
