Abstract
A first computer including a processor is programmed to receive an indication of a failure mode in a vehicle and wirelessly transmit the indication of the failure mode to a remote server. The computer is further programmed to receive a revised route to a destination based at least in part on the failure mode and operate the vehicle along the revised route.
Claims14
A system, comprising:
- a vehicle computer and a remote server,
- wherein the vehicle computer is programmed to:
- determine a first risk level for operating a vehicle based on (1) a trouble code indicating a failure of a specified vehicle electronic control unit or sensor and (2) stored data specifying the first risk level for the failure of the specified vehicle electronic control unit or sensor;
- transmit the first risk level to a remote server;
- then, after transmitting the first risk level, receive, from the remote server, an instruction to take an action;
- and
- operate the vehicle to take the action;
- and
- wherein the remote server is programmed to:
- receive the first risk level from the vehicle computer;
- based on the first risk level and additional data that includes a stored weight that is applied to the additional data, determine a second risk level for the failure of the specified vehicle electronic control unit or sensor;
- based on the second risk level, determine an action for the vehicle;
- and
- transmit the action to the vehicle computer.

A method comprising:
- determining a first risk level for operating a vehicle based on (1) a trouble code indicating a failure of a specified vehicle electronic control unit or sensor and (2) stored data specifying the first risk level for the failure of the specified vehicle electronic control unit or sensor;
- transmitting the first risk level from a vehicle computer to a remote server;
- receiving the first risk level in the remote server;
- based on the first risk level and additional data that includes a stored weight that is applied to the additional data, determining, in the remote server, a second risk level for the failure of the specified vehicle electronic control unit or sensor and, based on the second risk level, an action for the vehicle;
- then transmitting an instruction including the action from the remote server to the vehicle computer
- receiving, from the remote server, the instruction to take the action;
- and
- operating the vehicle to take the action.
