A cooling system includes a reactant material, a reactive material, a thermally managed control module, and a plunger. The reactive material is spaced apart from the reactant material. The thermally managed control module is configured to receive coolant from a coolant supply reservoir via a coolant supply channel. The plunger is movable between a retracted position and an extended position. When a temperature of the thermally managed control module is greater than a predetermined temperature, an actuator is configured to transition the plunger from the retracted position to the extended position and cause the reactive material to mix with the reactant material to create a second coolant via an endothermic reaction, and the second coolant enters the thermally managed control module via the coolant supply channel.

Secondary cooling system for control modules

A method and apparatus that perform threat zone assessment in a host vehicle are provided. The method includes detecting a target vehicle in a nonadjacent lane with respect to the host vehicle, determining dimensions of the detected target vehicle, a type of the detected target vehicle, and geometry of a road on which the detected target vehicle and the host vehicle are traveling, calculating the threat zone based on the dimensions of the detected target vehicle, the type of the detected target vehicle, or the geometry of the road on which the detected target vehicle and the host vehicle are traveling, and controlling the host vehicle to avoid the calculated threat zone by accelerating the host vehicle, decelerating the host vehicle, or aborting a lane change by the host vehicle.

Method and apparatus for threat zone assessment

A method of controlling a ground vehicle includes providing the vehicle with a first sensor configured to detect a vehicle position, a second sensor configured to detect a driven path of the vehicle, and a controller. The method also includes obtaining, via the first sensor, a plurality of vehicle position coordinates during a time interval of a drive cycle, and calculating, via the controller, a first path curvature parameter based on the plurality of vehicle position coordinates. The method additionally includes obtaining, via the second sensor, a second path curvature parameter based on the driven path during the time interval. The method further includes comparing, via the controller, the first path curvature parameter to the second path curvature parameter, and in response to a difference between the second path curvature and the first path curvature exceeding a threshold, automatically operating the controller according to a diagnostic mode.
