Abstract: A vehicle dynamic control monitoring system includes an electronic display, a vehicle dynamic control system (VDC), a tire pressure monitoring system (TPMS) system and an electronic controller. The electronic display, the VDC and the TPMS are all installed to a vehicle and are all connected to the electronic controller. The electronic controller is configured such that, in response to determining that at least one of the wheels has a tire pressure that is below a predetermined tire pressure range, a tire pressure warning signal is indicated by the electronic display, and in response to determining that at least one of the wheels has a tire pressure that is below the predetermined tire pressure range and the vehicle is moving above a predetermined vehicle speed, a VDC warning indicator is displayed on the electronic display indicating that the at least one VDC will operate with reduced effectiveness.

Abstract: A push arm is coupled to a vehicle frame proximate an intersection of a first side member and a first cross-member. A rear surface of the push arm is located adjacent to a front suspension structure with a gap defined therebetween. The push arm extends forward and laterally outward such that a front surface of the push arm is located outboard of and spaced apart from a front end of the first side member. An energy absorbing structure is positioned within the gap and is attached to the rear surface of the push arm and is spaced apart from the front suspension structure in a non-impacted state. The energy absorbing structure is configured such that in response to an off-center impact event, impact force to the energy absorbing structure pushes the energy absorbing structure into contact with the front suspension structure.

Abstract: A tire tread wear system may include one or more vehicle sensors and a processor. The processor may include a control module, a geometrical model, a machine learning model, and a switch. The geometrical model may be configured to collect data from the vehicle sensors to determine a dynamic rolling radius of a tire. The geometrical model may be configured to output a tread wear estimation based on the dynamic rolling radius of the tire. The machine learning model may be configured to collect data from the vehicle sensors. The machine learning model may be configured to output a tread wear estimation based on a correlation of the tread wear estimation output from the geometrical model and one or more data instances with a tire tread state. The switch may be configured to activate the geometrical model, the machine learning model, or a combination thereof.

Abstract: Autonomous driving simulation using recorded driving data is disclosed. A method of simulating autonomous driving includes receiving recorded driving data from a recorded autonomous vehicle (AV), the recorded driving data includes decision-making data generated using a first decision-making algorithm, sensing data, and movement data including positions of the recorded AV; obtaining simulation data from the recorded driving data by excluding the decision-making data from the recorded driving data; and simulating, by a simulation AV, a second decision-making algorithm using the simulation data. The simulating the second decision-making algorithm includes determining a first position of the simulation AV at a first time and adjusting a playback speed of the simulation data based on a difference between the first position and a second position of the positions of the recorded AV at the first time.

Abstract: World objects tracking and prediction by an autonomous vehicle (AV) is disclosed. A method includes identifying, based on first observation data received from sensors of the AV, an oncoming vehicle; identifying, based on second observation data received from the sensors of the AV, a road object; generating a lane-following hypothesis for the oncoming vehicle, the lane-following hypothesis indicating an intention that the oncoming vehicle remain in a current road lane; computing a lane-following reference driveline for the lane-following hypothesis of the oncoming vehicle; in response to determining that the lane-following reference driveline is blocked by the road object, generating a go-around hypothesis for the oncoming vehicle, and computing a go-around reference driveline for the go-around hypothesis; and providing at least one of a go-around trajectory corresponding to the go-around hypothesis or a lane-following trajectory corresponding to the lane-following hypothesis.

Abstract: Methods and systems for generating a solution path overlay interface to transmit a solution path are described. The disclosed technology includes receiving vehicle data and external data from a vehicle. The vehicle data includes a vehicle location and a vehicle destination, and the external data includes a location and a movement path for each of a plurality of external objects. A solution path is determined between the vehicle location and the vehicle destination, wherein the solution path does not intersect with the plurality of external objects. A solution path overlay interface is generated that includes the vehicle traveling the solution path and at least some of the plurality of external objects. The solution path overlay interface is outputted for display that is configured to receive a command from an operator which results in an updated solution path that is transmitted to the vehicle for execution.

Abstract: Multi-acid polymers are produced having the formula R—SO2—NH—(SO3−H+)n or R—SO2—NH—(PO3−H2+)n and made from a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form The R is one or more units of the polymer precursor without sulfonyl fluoride or sulfonyl chloride, n is one or more, and the multi-acid polymer has two or more proton conducting groups. A method of making the multi-acid polymers includes reacting an amino acid having multiple sulfonic acids or phosphonic acids with a polymer precursor in sulfonyl fluoride form or sulfonyl chloride form in a mild base condition to produce the multi-acid polymer having two or more proton conducting groups.

Abstract: A shifter assembly includes a housing, a shifter member, a movement restrictor, sensors and a positioning device. The housing has a chamber with magnetorheological fluid and an electromagnetic coil to selectively generate a plurality of levels of magnetic field densities through the magnetorheological fluid. The shifter member moves between at least a park position, a reverse position and a drive position. The movement restrictor is disposed within the chamber of the housing for movement between a first section of the chamber and a second section of the chamber. The magnetorheological fluid provides levels of movement resistance to the movement restrictor. The sensors are positioned to detect changes in position of the shifter member. The positioning device is configured to selectively position the shifter member to any of the park position, the reverse position and the drive position in response to electronic signals received by the positioning device.

Abstract: An autonomous vehicle includes a vehicle body, at least one detector, at least one display and at least one controller. The at least one detector is configured to detect a presence of an external object within a vicinity of the vehicle. The at least one display is supported on the vehicle body. The at least one controller is programmed to determine the presence of the external object upon detection of the external object by the detector. The controller is further programmed to display a rationale indicator on the display to a remote party within the vicinity of the vehicle based on a detection result of the detector indicating the presence of the external object. The rationale indicator is an indication of an external condition occurring in the vicinity of the vehicle.
