  • Publication number: 20230219561
    Abstract: Provided are methods for vehicle state estimation based on sensor data, which can include receiving the sensor data generated by one or more sensors, calculating a cornering stiffness value associated with the vehicle, predicting a lateral velocity value associated with the vehicle based on the cornering stiffness value, and outputting a set of vehicle state variables indicative of a current state of the vehicle at least by inputting the lateral velocity value into a recursive filter. Some methods described also include updating the cornering stiffness value based on the set of vehicle state variables, updating the lateral velocity value based on the updated cornering stiffness value, and updating the set of vehicle state variables based on the updated lateral velocity value. Systems and computer program products are also provided.

  • Publication number: 20230152796
    Abstract: Provided are systems and methods for vehicle control time delay compensation. Data associated with a vehicle state of the vehicle is provided. Data associated with at least one control parameter is received from the control system, the data generated by the control system based on the vehicle state. A time delay related to generation of the data associated with the at least one control parameter is determined by the control system, the time delay associated with a period of time from when the data associated with the vehicle state was transmitted to the control system to when the data associated with the at least one control parameter was received by the DBW system. A DBW parameter is determined based on the data associated with the at least one control parameter and the time delay, wherein the DBW parameter is used for traversal of a path by the vehicle.

  • Publication number: 20220289199
    Abstract: Among other things, systems and methods are described for brake arbitration. Safe stop requests are obtained. A safe stop request is associated with a deceleration value of a vehicle in motion. Safe stop activations associated with the safe stop request are determined, wherein the safe stop activations are associated with predetermined deceleration values. An automated emergency (AEB) system deceleration command is calculated. Arbitration is performed between the deceleration values associated with the safe stop request, predetermined deceleration values associated with the safe stop activations, and the deceleration value calculated from data captured by the AEB system to determine a final deceleration output.
