Abstract: Methods, computing systems, and technology are presented for providing voice assistance in a vehicle. For example, a computing system may be configured to access a first voice prompt indicative of a speech-based voice query provided by a user of the vehicle. The computing system may be configured to determine, based on the first voice prompt, a first prompt message corresponding to a text-based transcription of the first voice prompt. The computing system may be configured to process the first prompt message with a machine-learned large language model trained to generate a digital message response based on the first prompt message. The computing system may be configured to convert the digital message response to a speech-based voice response. The computing system may be configured to provide the speech-based voice response as audio output to the user of the vehicle.

Abstract: A method of controlling platooning of a lead vehicle and at least one follow vehicle traveling in a first lane of a roadway includes indicating an intended lane change of the lead vehicle to a second lane. A third vehicle is detected in a blind spot of the at least one follow vehicle preventing the at least one follow vehicle from changing lanes to the second lane. A signal is sent from the at least one follow vehicle to the lead vehicle indicative of the prevention of the at least one vehicle to change lanes to the second lane. The lead vehicle is automatically prevented from changing lanes to the second lane in response to the signal.
