Abstract: A redundant parking brake apparatus is provided for a vehicle having components of a parking brake system. The redundant parking brake apparatus comprises a first parking brake controller arranged to (i) monitor a first signal indicative of a request to apply parking brakes of the vehicle, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply the parking brakes in response to receiving the first signal. The redundant parking brake apparatus also comprises a second parking brake controller arranged to (i) initiate a timer counter in response to receiving the first signal, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply the parking brakes when the timer counter has reached a predetermined count.

Abstract: Embodiments are presented for trailer sway detection and braking distribution using a camera mirror system. In one embodiment, a vehicle controller is provided comprising: one or more processors; a non-transitory computer-readable medium; and program instructions stored on the non-transitory computer-readable medium. The program instructions, when executed by the one or more processors, cause the one or more processors to: monitor images captured by at least one image capture device to detect sway of a plurality of trailers being towed by a tractor; estimate a relative weight of each of the plurality of trailers based on the detected sway; determine braking force to apply to each of the plurality of trailers based on the estimated relative weight of each of the plurality of trailers; and send an electronic signal to a braking system of each of the plurality of trailers to apply the determined braking force to each of the plurality of trailers.

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: A system and method for controlling communications between members of a tractor-trailer along a power line extending between the members are provided. The system includes an input signal conditioning circuit including an amplifier and conditioning stage configured to convert an analog input signal from the power line to a digital input signal. The system further includes a controller configured to receive the digital input signal, identify a communication protocol for the analog input signal from among a plurality of communication protocols responsive to the digital input signal and decode the digital input signal using the communication protocol. The controller may also identify a communication protocol for an output signal on the power line from among the plurality of communication protocols and encode a digital communication using the communication protocol.

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.

Abstract: A system and method for assembling and using a map for supporting advanced driver assistance systems (ADAS) on a host vehicle are disclosed. The map indicates which roadway segments can support automated driving. The map may also indicate which vehicle sensor signal interpretation and vehicle control algorithms shall be used on those segments. The map may be assembled on a host vehicle, transmitted to a server and collated with maps from other vehicles equipped with ADAS. The host vehicle may download the other maps from the server for use in locations where the driver assistance sensor input from the host vehicle may not be dependable.
