Abstract: A system for calibrating signals received over a power line within a vehicle includes a signal conditioning circuit that converts the analog input signals into digital input signals. In one embodiment the circuit includes an adjustable gain circuit that outputs an amplifier gain signal establishing an amplifier gain level and an amplifier that outputs amplified signals responsive to the analog input signals and the amplifier gain signal. In another embodiment, the circuit includes a bias circuit that outputs a bias signal establishing a bias level and a comparator that generates the digital input signals responsive to the analog input signals and the bias signal. A controller receives the digital input signals and generates, depending on the embodiment, one or more control signals configured to control the configuration of the amplifier gain signal and amplifier gain level and/or the bias signal and the bias level.

Abstract: Sensor assemblies incorporating a temperature varying resistor provide information regarding the temperature of the operating environment for a sensor or protect the sensor from extreme temperatures. The assembly includes only two conductors—one transmitting current from a power source and another transmitting an output signal. In one embodiment, the assembly includes a sensor and a temperature varying resistor in parallel between the conductors with the output signal including information regarding a value of a variable measured by the sensor and information regarding a temperature of an operating environment for the sensor. In another embodiment, the sensor and temperature varying resistor are in series between the conductors with the output signal including information regarding a value of a variable measured by the sensor and the temperature varying resistor preventing delivery of current to the sensor when a temperature of the operating environment for the sensor meets a predetermined condition.

Abstract: A system and method for pre-trip inspection of a tractor trailer are provided. The system includes a communications gateway configured for electronic communication with a vehicle control system of the tractor-trailer and a computing device configured for communication with the vehicle control system through the communications gateway. The device is configured to display an instruction to a user to perform a task of the pre-trip inspection and receive an input associated with the task from the user. The input is indicative of an operating characteristic of the tractor-trailer. The device may be further configured to determine whether the operating characteristic meets a predetermined condition. The device is further configured to transmit an instruction to the vehicle control system through the communications gateway when the operating characteristic does not meet the predetermined condition. The instruction establishes a restriction on operation of the tractor-trailer.

Abstract: Various examples of park brake interface modules which are utilized as human machine interfaces (HMI) in vehicles are provided. In one example, a park brake interface module for a vehicle includes a park brake switch device to actuate the park brake. The park brake switch device is capable of actuating the vehicle park brake in a brake apply mode upon receipt of a pinch signal. In another example, the park brake interface module includes a park brake switch device which is capable of actuating the vehicle park brake in a brake release mode upon receipt of a reach signal. In a further example, the park brake interface module includes recessed fixed parking brake actuation switches. In operation, the electronic interface module and park brake switch devices allow the operator to apply or release the vehicle park brakes according to memorable mnemonics, for example, “pinch to park” and “reach to release.”

Abstract: A backup power supply system and a method for providing power to an electrical load are provided. The system includes at least one supercapacitor, a battery and a power supply controller. The controller is configured to determine whether an output of a primary power supply for the load meets a first predetermined condition, determine, when the output of the primary power supply does not meet the first predetermined condition, a level of current required by the load, provide current to the load from the supercapacitor if the level of current required by the load meets a second predetermined condition, and, provide current to the load from the battery if the level of current required by the load does not meet the second predetermined condition until an output of the battery meets a third predetermined condition and thereafter provide current to the load from the supercapacitor.

Abstract: Platoon management control systems and methods rearrange three of more vehicles cooperatively travelling seriatim as a platoon along an associated roadway into a platoon arrangement other than the linear or single file formation. Multi roadway lane platoon management control systems and methods control the three or more vehicles cooperatively travelling as a multi-lane platoon along an associated multi-lane roadway into a platoon arrangement other than the linear or single file formation. Larger platoon sizes are provided thereby enabling more vehicles to participate in the larger multi-lane platoon. A platoon management control uses a combination of the GPS position of the lead vehicle representative of the position of the vehicle relative to the associated geographical area, and braking performance data representative of the braking capabilities of following vehicles to rearrange the vehicles into the non-columnar formation.

Abstract: A system for demodulating and decoding received messages transmitted along a vehicle power line includes a reference signal generator, a timer, and a demodulation and decoding circuit. The circuit determines whether a message is present on the power line by identifying a symbol indicative of a message preamble, subsequently setting the timer to a time corresponding to a predetermined length of the message preamble, detecting, during the time, a plurality of symbols and determining whether the symbols indicate the presence of a message preamble. The circuit then extracts data from the message by activating the reference signal generator, adding the reference signal to the message to produce an equivalent signal, detecting a symbol in the equivalent signal indicative of the message data body, subsequently setting the timer to a time corresponding to a predetermined length of the message data body and detecting, during the time, a second plurality of symbols.

Abstract: A system for transmitting and receiving signals having varying frequencies along a power line within a vehicle is provided. A transceiver is configured to transmit output signals to and receive input signals from various electronic systems on a vehicle along a power line at a first frequency. A frequency control circuit determines whether the destination system for the output signal is configured to receive the output signal at the first frequency or a different frequency and modulates the frequency of the output signal if necessary. The frequency control circuit also determines, prior to receipt by the transceiver, whether the input signal has the first frequency or different frequency and modulates the frequency of the input signal if necessary.
