Methods and systems are provided for estimating weight-related parameter values of a vehicle. The system includes a sensor system, a display device, and a controller configured to, by a processor, receive, from the sensor system, static sensor data sensed while the vehicle is stationary and coupled to a trailer and dynamic sensor data while the vehicle is being driven and not coupled to the trailer, wherein the static sensor data includes a deflection value associated with a suspension system of the vehicle, estimate, while the vehicle is stationary, one or more weight-related parameter values using a suspension model and the static sensor data, determine degradation of the suspension system over time using a suspension sag estimation model and the dynamic sensor data, update the suspension model to accommodate for the degradation of the suspension system, and display the one or more weight-related parameter values on the visual display.

Vehicles and related systems and methods are provided for assisting vehicle operation. A detection service obtains a current object location derived from one or more sensors onboard a vehicle, determines a current deviation metric associated with the current object location based on a relationship between the current object location and a preceding object location derived from the one or more sensors, and classifies the current object location into one of a plurality of different classifications based on the current deviation metric value, where a primary subset of object locations has respective values for the deviation metric that are less than a threshold. The detection service monitors a predicted path associated with the vehicle with at least the most recent object location of the primary subset to generate an alert in response to a predicted intersection with the predicted path.

Vehicle systems and collision detection methods with occlusion mitigation

Methods and systems for a vehicle of a remote transportation system. A vehicle includes a non-transitory computer readable media and one or more processors configured by programming instructions on the non-transitory computer readable media to: coordinate a platooning operation between the first vehicle and a second vehicle; monitor an environment of the first vehicle and the second vehicle while platooning; in response to the monitoring, determine a threat level vassociated with a cut-in operation of at least one object within the environment; and selectively activate at least one visual or audio cue based on the threat level to avoid the cut-in operation.

A system and method for surround view egress assistance that includes detecting, by a sensor in a vehicle, an obstacle in a swing path of a vehicle door. The method includes predicting, based on a geometrical analysis, one or more potential collision zones between the obstacle and the vehicle door. The predicting also includes determining a bank angle of the vehicle in the predicting of one or more potential collision zones. The method further includes estimating, based on data from an inertial measurement unit, a severity of an impact of the vehicle door with the obstacle. The method also includes detecting a color and height of a curb and potential collisions with a vehicle door.

A monocular camera system for a vehicle includes a front mono camera, a side mono camera, and one or more controllers in electronic communication with the front mono camera and the side mono camera. The one or more controllers execute instructions to determine an ideal lagged distance the vehicle travels between a current time step and a previous time step as two asynchronous camera frames are captured by the front mono camera and the side mono camera, determine a number of delayed frames captured by either the front mono camera or the side mono camera between the current time step and the previous time step based on the ideal lagged distance. The controllers determine a direction of travel of the vehicle that indicates which mono camera is selected to provide a previous camera frame captured at the previous time step.

A vibration monitoring system includes a plurality of encoders and an analyzer. The encoders are configured to generate multiple pulse train signals for multiple wheels. Each encoder is coupled to a respective one of the multiple wheels and generates a single one of the pulse train signals. The analyzer is coupled to the encoders and is configured to generate multiple pulse per revolution signals and multiple angular velocity signals for the wheels in response to the pulse train signals. Each pulse per revolution signal conveys a single pulse per rotation of the respective wheel. The analyzer is further configured to generate an input phasor array representative of the pulse per revolution signals, generate a response phasor array in response to the angular velocity signals for the wheels, and generate a report that identifies at least one vibrating wheel in response to the input phasor array and the response phasor array.
