摘要： A device for detecting nefarious communication signals in a vehicle includes a detection support logic, a nefarious logic, a filtering circuit, and a microcontroller. The device receives a measurement signal from the detection support logic. The device determines a characteristic of an alternating current (AC) signal during communication at a first time on a wiring harness of the vehicle based on the measurement signal. The device determines the characteristic of the AC signal at a second time based on the measurement signal. The device determines that the characteristic measured during the first time differs from the characteristic measured during the second time. The device transmits a blocking signal to the nefarious logic to filter a frequency band of a communication conductor of the wiring harness in response to the determination that the characteristic measured during the first time differs from the characteristic measured during the second time.

摘要： 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.”

摘要： The system assigns a plurality of drivers to one or more identified routes. An onboard computing system of a vehicle collects or generates a plurality of vehicle events, which are received at a server via a network. The onboard computing system includes a plurality of sensors and subsystems that are connected to monitor various vehicle components, such as braking, steering, and radar, as well as one or more cameras. A difficulty of each of the identified routes is characterized based on the plurality of vehicle events. A performance of each driver is characterized based on a subset of the plurality of vehicle events collected or received from the vehicle of each driver.

摘要： Various examples of a controller, method and system for determining positions of a tractor-trailer vehicle train are disclosed. In one example a tractor controller is manually-initiated or a user-initiated tractor controller and includes an electrical control port for receiving an electrical start signal, and a communications port for receiving data. A processing unit of the tractor controller includes control logic and is in communication with the electrical control port. The control logic is capable of receiving, in response to the electrical start signal, a data signal at the communications port which includes a GPS signal and a unique identification which corresponds to the towed vehicle. At a predetermined response time, the tractor controller determines the position of the towed vehicle in the tractor-trailer vehicle train based on the data received from the towed vehicles.

摘要： A vehicle lane management system and a method of operating a vehicle lane management system is provided. The lane management system minimizes unnecessary driver warnings regarding lane departure and/or vehicle operation intervention actions to alter lane position when a vehicle is to be operated in a turn in conditions where the driver is or will be intentionally placing wheels of the vehicle outside of lane boundaries. The conditions for suppressing lane departure warnings and/or interventions include a vehicle speed being below a threshold speed and an upcoming turn radius being below a predetermined minimum turn radius.

摘要： A one piece drum brake spider construction eliminates welds and distortion, at least relative to a typically fabricated spider, and should improve brake performance. The spider includes a main body plate having opposed flat sides, an outer perimeter, and an inner perimeter configured to receive an axle tube. Vibration control structure is preferably formed on at least one of the opposed flat sides of the main body plate, and the brake drum spider additionally includes weight minimizing features. At least the main body plate may be produced by any of a casting technique, a stamping technique, a machining technique, and an additive manufacturing technique. The invention also concerns a process of producing such a brake drum spider.

摘要： A method for determining a presence of an occupant within a vehicle includes capturing, via a driver facing camera, video image data, including a plurality of image frames of a field-of-view of the driver facing camera. At least one area-of-interest within the image frames is defined, and a foreground pixel count of each image frame of each area-of-interest is determined. At each Nth image frame, an occupancy for each area of interest is determined based at least in part on the foreground pixel count. The occupancy indicates whether the occupant is present or absent in the respective area-of-interest. A history of the occupancy determination for each area-of-interest is maintained, and a final status for each area-of-interest is determined based on the respective history of occupancy. External indicators are initiated based on the final status determination.

摘要： A system controlling an electronic parking brake of a vehicle includes an input device receiving an input pattern from an operator and a parking brake controller receiving the input pattern from the input device. The parking brake controller determines if the input pattern is a respective predetermined pattern for setting the electronic parking brake to one of a primary mode and a secondary mode. If the parking brake controller determines the input pattern is the predetermined pattern for setting the electronic parking brake to the secondary mode, the parking brake controller transmits an electronic control signal for releasing the electronic parking brake until a subsequent input pattern received by the input device is the predetermined pattern for setting the electronic parking brake to the primary mode.

摘要： A method for transmitting event data from an event detection and reporting system in a vehicle to a backend server includes storing full resolution sensor data in a vehicle buffer memory and subsampling the full resolution sensor data to produce reduced resolution of the sensor data. A vehicle event is detected based on an analysis of the reduced resolution sensor data, and the vehicle event is classified based on the reduced resolution sensor data. A determination is made as to whether the vehicle event is classified as a particular type of event with a minimum degree of confidence. The method then includes transmitting an indication that the vehicle event has not been classified with the minimum degree of confidence when the vehicle event has not been classified with the minimum degree of confidence, and transmitting reduced resolution sensor data for the detected vehicle event when the vehicle event is classified with at least the minimum degree of confidence.
