Abstract: A friction washer for a limited slip differential is provided, with the friction washer including a disk body having first and second opposing surfaces. The first and second opposing surfaces define respective first and second contact planes and include recesses that extend into the disk body from the respective first and second contact planes such that only a portion of the disk body extends to the respective first and second contact plane. The recesses are defined by partial spherical or partial cylindrical surfaces. This provides improved properties for holding lubricating fluid circulated within the differential so that the hydrodynamic pressure created between the friction surfaces provides a more consistent film or boundary layer of the lubricating fluid for a more uniform coefficient of friction over various operating speeds and pressures.

Abstract: Perception systems and methods include use of occlusion constraints for resolving tracks from multiple types of sensors. An occlusion constraint is applied to an association between a radar track and vision track to indicate a probability of occlusion. The perception systems and methods refrain from evaluating occluded and collected radar tracks and vision tracks. The probability of occlusion is utilized for deemphasizing pairs of radar tracks and vision tracks with a high likelihood of occlusion and therefore, not useful for tracking. Improved perception data is provided and more closely represents multiple complex data sets for a vehicle to prevent a collision with an occluded object as the vehicle operates in an environment.

Abstract: Circuits, devices and systems that include a low voltage test for common mode transient immunity (CMTI). The CMTI test of this disclosure may be used in a variety of applications, such as a data transmission circuit configured to communicate across galvanic isolation. A differential circuit may include two signal paths. For robust common mode transient rejection, the first signal path should be the same as the second signal path. Differences in the resistance, inductance, and capacitance between the two signal paths may result in common mode noise being measured as a differential signal at the output terminals. Devices according to the techniques of this disclosure are configured to enter a test mode to conduct a low voltage test that outputs a measurement of CMTI at any phase of production or field use.

Abstract: The techniques and systems herein enable ESA modification based on manual steering inputs. Specifically, a score is determined for a manual steering input to a host vehicle while an ESA is actively applying an ESA steering input to the host vehicle. The score quantifies an amount of additional steering input relative to the ESA steering input (e.g. additional steering angle, steering wheel torque). The ESA steering input is maintained, modified, or canceled based on the score. By doing so, the system is able to effectively adapt the ESA to the manual steering inputs thereby allowing for effective collision mitigation while ensuring that the vehicles operate as intended by the drivers.

An installation space-saving and safe control unit is rendered possible owing to the fact that the plug housing forms a dielectric resistance between the clamping contact and the valve housing.
