  • Patent number: 12256432
    Abstract: A wireless communication system for a vehicle includes a wireless access point (AP), an ultra-wide band (UWB) system, a communication link, a controller, and a vehicle system. The UWB system is in communication with the wireless AP via a communication link. The wireless communication system is operable to detect, via the wireless AP, a request for localized wireless communication. The UWB system requests the wireless AP to generate a clear to send (CTS) transmission, which includes selecting an ultra-wide band (UWB) channel, mapping the UWB channel to a plurality of WiFi channels, and transmitting, by the wireless AP, the CTS transmission to each of the plurality of WiFi channels. The UWB system then transmits a UWB message.

  • Patent number: 12252156
    Abstract: A method of operating an autonomous racetrack driver coach and demonstrator in an autonomous vehicle employing operating systems for propulsion and maneuvering includes identifying a road course and mapping a velocity profile and a trajectory for the vehicle via a remote configurator. The trajectory defines a vehicle path around the road course and with the velocity profile minimizes the vehicle's lap time. The method also includes determining a presence of a human passenger/operator in the vehicle. The method additionally includes determining, via an electronic controller in communication with a remote detection source, localization of the vehicle on the road course. The method also includes determining vehicle velocity, acceleration, and heading relative to the mapped trajectory.

  • Publication number: 20250088574
    Abstract: A unified electronic control unit (ECU) interface provides a bridge from ECU clients to the ECU. The ECU interface may be implemented on a vehicle's onboard computer, and it may be used by clients executing on the onboard computer and, in some cases, by clients outside the onboard computer. The ECU interface may receive a request from a client in a first messaging format, e.g., a local networking protocol used by processes running on the vehicle. The ECU interface translates the request into a second messaging format and transmits the request to the ECU. The ECU interface receives a response from the ECU and translates the response into the first messaging format for delivery to the client. The ECU interface may further perform authentication of the client and/or the ECU, packet serialization of the response from the ECU, packet diagnostics, and other functionalities associated with communicating with the ECU.
