Abstract: A method of diagnosing a leak in a coolant system of an automobile includes repeatedly measuring the coolant level within the coolant system at a pre-determined time interval, calculating a short term leak rate, wherein the short term leak rate is the rate of coolant leakage over a first pre-determined length of time, calculating a long term leak rate, wherein the long term leak rate is the rate of coolant leakage over a second pre-determined length of time, further wherein the second pre-determined length of time is longer than the first pre-determined length of time, identifying a coolant system leakage state based on a current coolant level within the coolant system, the short term leak rate, and the long term leak rate, and providing notification of the coolant system leakage state to an operator of the vehicle.

Abstract: A thermal management device for dissipating heat from an electrical component includes a volume of working fluid configured to change from a liquid state to a vapor state in response to being heated by the electrical component. The thermal management device also includes a working fluid chamber configured to move the working fluid. The working fluid chamber includes an impermeable outer portion and a porous inner portion integrally formed with and connected to the impermeable outer portion. The inner portion is configured to move the working fluid when in the liquid state toward the electrical component. The impermeable outer portion is made of a first material and the porous inner portion is made of a second material. The first material is different from the second material.

Abstract: Vehicles and methods are provided for monitoring the health of a substrate and a protective coating disposed on the substrate. A vehicle includes a substrate, a protective coating, a coating deformation sensor, and a controller. The protective coating is disposed overtop the substrate. The coating deformation sensor is operatively coupled with the protective coating and configured to measure a deformation value of the protective coating. The controller is configured to: determine a deformation recovery rate of the protective coating based on the deformation value; determine whether the deformation recovery rate corresponds with an expected recovery rate of the protective coating; and indicate that the protective coating may be impaired in response to determining that the deformation recovery rate does not correspond with the expected recovery rate.

Abstract: A vehicle control system includes a plurality of components that are disposed to effect a vehicle function and a controller in communication with the plurality of components. A method for controlling the vehicle includes monitoring states of health (SOHs) of the plurality of components. Upon detecting a change in status of the SOH of the subject component, an allowable window of operation for the subject component and an allowable window of operation for the related component are determined, and operating constraints related to the vehicle function are determined based upon the allowable windows of operation for the subject component and the related component. Operation of the vehicle is controlled subject to the operating constraints related to the vehicle function.

Abstract: A method and associated device for automated maintenance scheduling for an autonomous vehicle includes monitoring a state of health (SOH) of an on-vehicle subsystem and monitoring an appointment log associated with a vehicle operator. Upon detecting a change in the SOH of the on-vehicle subsystem, the method includes communicating with a service center to determine a recommended maintenance action associated with the change in the SOH of the on-vehicle subsystem and to determine a proposed service appointment for the autonomous vehicle to effect the recommended maintenance action. The proposed service appointment is coordinated with the appointment log, and verified with the vehicle operator. A service appointment is scheduled based upon the proposed service appointment when verified by the vehicle operator. The appointment log is updated to include the service appointment.
