BLIND SPOT GUIDANCE SYSTEM FOR A VEHICLE
A blind spot guidance system for a vehicle includes a perception system, an electric motor, and one or more controllers. The one or more controllers execute instructions to monitor a trajectory of the vehicle to determine when a lane change maneuver to manipulate the vehicle from a current lane of travel to an adjacent lane of travel is being initiated. In response to determining the lane change maneuver is being initiated, the one or more controllers monitor the perception system for a moving obstacle located in a blind spot of the vehicle. In response to determining the moving obstacle is located in the blind spot of the vehicle, the one or more controllers instruct the electric motor to generate an assist torque provided to a hand wheel, wherein the assist torque guides the vehicle back into the current lane of travel.

System and method to stabilize motorcycles
Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as weave. A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.
