Abstract: A first device, for communications on a communications bus is programmed to: identify a configuration on a communications bus comprising one of (1) a second LIN device and no second custom device, (2) the second custom device and no LIN device, and (3) both the second LIN device and the second custom device and select an operating mode specified for communications with the identified bus configuration. A third device for communications on the communications bus is programmed to identify that a fourth device on the communications bus is one of (1) a calibration device programmed to control two-way communications with the third device, (2) a LIN master device programmed to control two-way communications with the third device and (3) a custom master device programmed to only receive messages from the third device; and select an operating mode specified for communication with the other device.

Abstract: A climate control filter monitoring system includes a control module adapted to periodically set a climate control system to a filter test configuration, test the filter and then indicate when the climate control system filter needs changing or cleaning.

Abstract: An auxiliary heating system for a vehicle interacts with an ignition controller having a Run state in which an engine of the vehicle is running and an Off state in which the engine is not running. An auxiliary heater has a Parking mode for heating a passenger cabin of the vehicle when the ignition controller is in the Off state. An auxiliary heater controller has a user-configurable setting for selectably entering the Parking mode when the ignition controller enters the Off state. A manual interface is responsive to a user to provide user commands to the auxiliary heater controller including setting commands during the Run state for determining the user-configurable setting and a cancel command during the Off state for terminating the Parking mode.

Abstract: A heat transfer system is provided for a road vehicle having a passenger cabin. A primary branch includes a primary pump and a primary power plant. An auxiliary branch includes an auxiliary coolant pump, an auxiliary heat source, and a cabin heat exchanger. A thermostatic multi-way valve directs coolant from a valve inlet to substantially only a first valve outlet when receiving coolant below a first temperature. The valve directs coolant from the valve inlet to substantially only a second valve outlet when receiving coolant above a second temperature. The valve inlet is coupled to receive coolant from either the primary branch or the auxiliary branch. The first valve outlet is configured to return coolant to the same branch as is connected to the valve inlet. The second valve outlet is configured to direct coolant to the other branch to which the valve inlet is not connected.

Abstract: An air quality monitoring system for a motor vehicle includes a plurality of air sampling points on the motor vehicle, a single air quality sensor and a conduit system connecting the plurality of air sampling points with the single air quality sensor.

Abstract: A thermal management system for an automotive vehicle includes air cooled heat exchangers for an HVAC system, for a prime mover, and for various electronics componentry. All heat exchangers are cooled by a common air stream flowing from the ambient. The amount of heat imparted to the air stream through the HVAC system is controlled as to permit optimal cooling of the vehicle electronics and vehicle prime mover.
