摘要: A system and method including receiving a plurality of messages generated by a vehicle, each of the messages being associated with an indicated topic; initializing one or more state machines, each state machine preconfigured with a one or more specified state parameters to define a specific scenario, the initializing commencing an execution of the one or more state machines; querying the plurality of messages by the one or more state machines, each state machine querying for messages having an indicated topic associated with the querying state machine; updating, at one or more of a sequence of time intervals of a time period, the one or more state machines based on state transitions determined for each state machine; updating, based on each of the one or more state machines, a scenario record for each of the one or more state machines; and storing the updated scenario record in a data store.

摘要: Provided are systems and methods for controlling a vehicle based on a map that designed using a factor graph. Because the map is designed using a factor graph, positions of the road can be modified in real-time while operating the vehicle. In one example, the method may include storing a map which is associated with a factor graph of variable nodes representing a plurality of constraints that define positions of lane lines in a road and factor nodes between the variable nodes on the factor graph which define positioning constraints amongst the variable nodes, receiving an indication from the road using a sensor of a vehicle, updating positions of the variable nodes based on the indication and an estimated location of the vehicle within the map, and issue commands capable of controlling a steering operation of the vehicle based on the updated positions of the factor nodes.

摘要: Provided are systems and methods for detecting a vehicle with sensors that are not calibrated properly and calibrating such sensor in real-time. In one example, a method may include iteratively capturing sensor data of a road while the vehicle is travelling on the road; monitoring a calibration of the sensors of the vehicle based on the sensor data, determining that the sensors of the vehicle are not calibrated properly based on the monitoring, generating a calibration target of an object on the road based on the sensor data, and adjusting a calibration parameter of the one or more sensors of the vehicle based on the generated calibration target.

摘要: Provided is a system and method for interfacing with physical input mechanisms of a vehicle and electrically controlling signals from the physical input mechanisms to a computer of the vehicle. Examples of such physical input mechanisms include a gas pedal, a brake pedal, a turn signal stalk, a button, and the like. In one example, the method may include receiving, via a first interface, a request to actuate a component of a vehicle that is controlled by a physical input mechanism, generating, via a processor, a control signal that corresponds to an actuation signal from the physical input mechanism, and transmitting, via a second interface, the generated control signal to a control unit of the vehicle for actuating the component of the vehicle.

摘要: Provided are systems and methods for auto calibrating a vehicle using a calibration target that is generated from the vehicle's sensor data. In one example, the method may include receiving sensor data associated with a road captured by one or more sensors of a vehicle, identifying lane line data points within the sensor data, generating a representation which includes positions of a plurality of lane lines of the road based on the identified lane line data points, and adjusting a calibration parameter of a sensor from among the one or more sensors of the vehicle based on the representation of the plurality of lane lines.
