摘要： A towing configuration of a vehicle coupled to a trailer may be evaluated by rolling a tire of the coupled vehicle and trailer over a compressible region of a pressure vessel filled with a hydraulic fluid. A peak pressure of the hydraulic fluid as the tire rolls over the compressible region of the pressure vessel may be determined. The tire load may be determined based upon the peak pressure. Based at least in part on the tire load, a determination may be made whether the towing configuration satisfies a predetermined set of criteria.

摘要： Methods and apparatus are provided for cleaning a sensor lens cover for an optical vehicle sensor. The method includes monitoring the sensor lens cover for a contaminant obstructing at least a portion of the sensor lens cover and determining the presence of the commandant and a contaminant type using information provided by one or more vehicle sensors. A cleaning modality selected based the contaminant type is activated and it is determined whether the cleaning modality has removed the contaminant from the sensor lens cover.

摘要： A forward facing camera module is configured to, based on an image including a predetermined field of view (FOV) in front of the vehicle: determine a first distance between the vehicle and a first cyclist. A blind zone radar sensor module is configured to: determine a second distance between the vehicle and a second cyclist within a predetermined area on a side of the vehicle based on radar signals transmitted within the predetermined area. A first and second distance modules are configured to generate first and second signals when the first and second distances are decreasing, respectively. An output control module is configured to, when at least one of the first signal and the second signal is generated while a turn light for the side of the vehicle is activated, selectively generate at least one of an audible output and a visual output within a passenger compartment of the vehicle.

摘要： A passive entry passive start (PEPS) system is provided for performing at least one PEPS function with respect to a vehicle as an end device (e.g., smart phone or key fob, etc.) approaches the vehicle and comes within range for authorization. The vehicle includes a plurality of sensors and a central module. The central module is communicatively coupled to the end device and to the sensors via short-range wireless connections. The central module can determine, based on signal strength information provided from the sensors or the end device, whether the end device is within range for authorization. When the end device is determined to be within range for authorization, the central module can control performance of at least one PEPS function at the vehicle.

摘要： A dimension calculation system in a host vehicle for dynamically calculating a vehicle dimension using solar shadow information is disclosed. The system is configured to: calculate solar position and an expected vehicle shadow based on geocode location, time and vehicle dynamics; detect an actual vehicle shadow in an image from a vehicle camera; compare the actual vehicle shadow to an expected vehicle shadow; determine a dimension profile and max height point for a vehicle plus vehicle cargo based on a comparison of the actual vehicle shadow to the expected vehicle shadow; calculate a confidence level for the dimension profile and max height point for the vehicle plus cargo; and use the dimension profile and max height point to provide one or more dimension notifications when the confidence level for the dimension profile and max height point for the vehicle plus cargo are above a first threshold level.

摘要： A method for dampening trailer sway, includes: receiving, by a controller of a vehicle system that is coupled to a trailer, a vehicle speed signal of the vehicle system, wherein the vehicle speed signal is indicative of a vehicle speed of the vehicle system; determining a friction force to be applied to the trailer by an actuator using the vehicle speed of the vehicle system and a graph that establishes a relationship between the friction force to be applied to the trailer and the vehicle speed; and adjusting, by the controller, the graph that establishes the relationship between the friction force and the vehicle speed using the decay rate of the plurality of oscillation amplitudes to create an updated graph.

摘要： Systems are provided for assisting in towing a trailer by a lead vehicle. A wheeled tow assist unit couples between the lead vehicle and the trailer. A drive unit onboard the tow assist unit drives the wheels in response to a force between the trailer and the tow assist unit. The tow assist unit bears at least a portion of the force required to tow the trailer.

摘要： A self-cleaning lens system disposed adjacent a camera is disposed. The system may incorporate a piezoelectric (PZT) lens system having a first PZT element secured to a first peripheral portion of the lens element, which may be responsive to an alternating current (AC) signal applied to the first PZT element. An AC signal may excite the first PZT element to cause shear displacements in opposite longitudinal directions and to create an oscillating shear motion for the first PZT element. The oscillating shear motion may cause an oscillating rotational movement of the lens element that removes the environmental element from a surface of the lens element.
