Vehicle steering system having a user experience based automated driving to manual driving transition system and method

A steer by wire steering system includes a steering wheel selectively coupled to a steering shaft, the steering wheel and steering shaft axially movable between a deployed position and a retracted position; an advanced driver assist system configured to steer the steerable wheels of a vehicle that is in communication with the steering wheel and steering shaft, the ADAS configured to selectively control the steering of the steerable wheels in an autonomous driving mode and a manual driving mode; and a steering system controller in communication with the ADAS, the steering system controller programmed to, while the steering wheel is in the retracted position, move the steering wheel to the deployed position and operatively couple the steering wheel to the steering shaft, in response to a vehicle operator request to deactivate a portion of the ADAS and transition from the autonomous driving mode to the manual driving mode.

ELECTRIC POWER STEERING TORQUE COMPENSATION
20200239067 · 2020-07-30 ·

Among other things, we describe techniques for electric power steering torque compensation. Techniques are provided for a method implemented by a computer, e.g., a computer onboard an autonomous vehicle. A planning circuit onboard the vehicle and connected to an EPS of the vehicle determines a compensatory torque signal to modify an actual steering angle of a steering wheel of the vehicle to match an expected steering angle of the steering wheel. The planning circuit transmits the compensatory torque signal to a control circuit that controls the steering angle of the steering wheel. The EPS modifies the actual steering angle based on the compensatory torque signal resulting in a modified steering angle. The control circuit operates the vehicle based on the modified steering angle.

SYSTEMS AND METHODS FOR DETERMINING PATH CONFIDENCE FOR UNMANNED VEHICLES

Examples implementations relate to determining path confidence for a vehicle. An example method includes receiving a request for a vehicle to navigate a target location. The method further includes determining a navigation path for the vehicle to traverse a first segment of the target location based on a plurality of prior navigation paths previously determined for traversal of segments similar to the first segment of the target location. The method also includes determining a confidence level associated with the navigation path. Based on the determined confidence level, the method additionally includes selecting a navigation mode for the vehicle from a plurality of navigation modes corresponding to a plurality of levels of remote assistance. The method further includes causing the vehicle to traverse the first segment of the target location using a level of remote assistance corresponding to the selected navigation mode for the vehicle.

METHOD FOR TRAJECTORY PLANNING OF A MOVABLE OBJECT

A method for determining a movement trajectory (MT) for a movable object (a vehicle) in a rule-based trajectory planning (TP) system, TP being performed based on minimizing overall costs of a cost function (CF), the CF considering violation costs (VC) which arise for each MT section from a potential respective violation of violatable rules as to the section, the rule violation (RV) including a state/transition RV, the state RV indicating a violation of a state rule indicating an impermissible state of the object; the transition RV indicating a violation of a transition rule indicating an impermissible state transition, the state RV being assigned a time-dependent cost amount of the VC, and the transition RV being assigned a fixed, time-independent cost amount of the VC, so that overall costs for a MT for each section violating a violatable rule depend on the time-dependent/fixed cost amount assigned to the violated rule.
