Systems, methods, and other embodiments described herein relate to updating vehicle software by using additional connectivity from an alternate device. In one embodiment, a method includes initiating a download from a first point and a second point within a software package by a communication module associated with a vehicle and an alternate device. The method also includes, responsive to comparing progress points of the download between the communication module and the alternate device, adapting the download according to the progress points and network connectivity by the communication module to complete the download, the first point and the second point being opposing ends within the software package.

Systems and methods for updating vehicle software

A system for updating software installed on an electronic unit on a vehicle can include a processor and a memory. The processor can be disposed on an intermediate communications device. The intermediate communications device can be a mobile device. The memory can store an update request module and an update existence module. The update request module can include instructions that when executed by the processor cause the processor to receive, from the electronic unit on the vehicle, a request for an update of the software. The request can include: (1) an identification of a version of the software currently installed on the electronic unit and (2) a key to specifically identify the electronic unit. The update existence module can include instructions that when executed by the processor cause the processor to receive, from a device associated with development of the software, information about an existence of the update.

Updating software installed on an electronic unit on a vehicle

Vehicle-to-vehicle (V2V) communication through short range communication techniques can be extended by sending messages from a host vehicle to a target vehicle using an intermediate vehicle. The host vehicle identifies road conditions which may be of interest to a target vehicle. An intermediate vehicle relays the message detailing the identified road conditions from the host vehicle to the target vehicle. The message can be rebroadcast by the intermediate vehicle to target vehicles in its communication range, or it can generate a new message to transmit the information to target vehicles.

Intermediate vehicle repeater for out of range vehicles

A back-propagating intersection collision avoidance system is provided. The system can include a first vehicle and a second vehicle, the first and second vehicles each operable to approach an intersection at a definable velocity and acceleration. In addition, the intersection can have a collision zone in which the first and second vehicles will collide if they are present there at the same time. The first vehicle can have a processing unit with a controller and a microprocessor, the microprocessor having an algorithm with a disturbance model. The processing unit is operable to back-propagate from the collision zone a capture set as a function of a disturbance for the first and second vehicles.
