Rollover control algorithm

Abstract:

According to one embodiment, a vehicle can be implemented with a drive-by-wire controller which operates subsystems of the vehicle such as throttle, brakes, and steering based on electrical signals from transducers on the vehicle controls and without a direct physical link between the controls, such as the steering wheel, and the components of the corresponding vehicle subsystem. In such cases, the stability control feature of the vehicle can be adapted to detect conditions such as oversteering which can make the vehicle unstable and unsafe and can adjust the steering and other controls of the vehicle to correct the unstable or unsafe condition regardless of the physical input on the steering wheel and other controls.
