1. A system, comprising a controller for a vehicle sub-system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- receive a first message and a second message, wherein the first message includes at least a command for the controller, and the second message includes at least a target value for the controller to achieve, wherein the target value is provided along with a series of values and a corresponding set of parameters according to which additional target values can be estimated, the parameters including at least one of a time traveled parameter and a distance traveled parameter;
detect a fault with respect to the first message; and
locally determine an adjustment to the sub-system to achieve the target value.

Abstract
A vehicle sub-system controller is configured to receive a first message and a second message, wherein the first message includes at least a command for the controller, and the second message includes at least a target value for the controller to achieve. A fault may be detected with respect to the first message; and an adjustment to the sub-system may be locally determined in the sub-system controller to achieve the target value.

15. A system, comprising a controller for a vehicle sub-system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
-
receive a first message and a second message, wherein the first message includes at least a command for the controller, and the second message includes at least two target values for the controller to achieve, wherein the second message further includes at least one of a time parameter and a distance parameter, and also coefficients for a function with sub-functions, each of the sub-functions corresponding to one of the target values as well as at least one of the parameters; detect a fault with respect to the first message; and locally determine an adjustment to the sub-system to achieve the target values by using the sub-functions. - View Dependent Claims (16, 17, 18, 19)
