IDENTIFICATION AND MITIGATION CONTROL OF PULL FORCE IMPACTS WHEN PASSING LARGE VEHICLES IN AUTOMATED DRIVING
Methods and systems are provided for determining and mitigating vehicle pull force from passing other vehicles. In an exemplary embodiment, methods and systems are provided that include: obtaining sensor data via one or more sensors of a vehicle, the sensor data including both perception sensor data and vehicle dynamics sensor data; identifying, via a processor, one or more additional vehicles to be passed by the vehicle, using the perception sensor data; and predicting and determining, via the processor, a pull force for the vehicle that is caused by the passing of the vehicle by the one or more additional vehicles along with an impact of the pull force on the vehicle, based on both the perception sensor data and the vehicle dynamics sensor data, and control the vehicle to proactively mitigate the pull force on the vehicle; and vehicle with trailer when towing
APPLICATIONS FOR USING MASS ESTIMATIONS FOR VEHICLES
Various applications for use of mass estimations of a vehicle, including to control operation of the vehicle, sharing the mass estimation with other vehicles and/or a Network Operations Center (NOC), organizing vehicles operating in a platoon and/or partially controlling the operation of one or more vehicles operating in a platoon based on the relative mass estimations between the platooning vehicles. When vehicles are operating in a platoon, the relative mass between a lead and a following vehicle may be used to scale torque and/or brake commands generated by the lead vehicle and sent to the following vehicle.
DISTRIBUTED SAFETY MONITORS FOR AUTOMATED VEHICLES
Controllers, control architectures, systems and methods are described for controlling a host vehicle's participation in a platoon. In some embodiments, a vehicle control system includes a vehicle controller configured to determine vehicle control commands for at least partially automatically controlling the host vehicle based at least in part on sensor information. The vehicle control commands are arranged to be directly or indirectly utilized by one or more host vehicle control units resident on the host vehicle. The vehicle control system also includes one or more safety monitoring algorithms that, during at least partially automated driving, verify that selected vehicle control commands received from the vehicle controller meet selected safety criteria. At least some of the safety algorithms utilize sensor data in the verification of the commands received from the vehicle controller. The sensor data used by the safety algorithms may come from the host vehicle and/or a second vehicle.
Vehicle control system and method
Aspects of the present invention relates to a vehicle control system (1) for controlling a vehicle transfer case (3). The transfer case (3) is operable in a high range and a low range. The vehicle control system (1) is configured to output a range change signal to implement a transfer case range change.

Control system and method for a trailer or dolly
A control system for a trailer or dolly, wherein the trailer or dolly comprises a perception sensor which is directed in a first travelling direction of the trailer or dolly and a coupling member for coupling with a vehicle further ahead in the first travelling direction, wherein the control system is configured to provide and/or use data from the sensor for a first control mode when the trailer or dolly is not coupled to the vehicle via the coupling member and to provide and/or use data from the sensor for a second control mode different from the first control mode when the trailer or dolly is coupled to the vehicle via the coupling member.
Determining a distance between a camera and a hitch ball
A system for determining a distance between a camera and a hitch ball of a vehicle. The system includes a camera configured to be mounted on a vehicle and an electronic processor connected to the camera. The electronic processor is configured to determine a first position and a second position associated with a point on a trailer, determine an angle of rotation between the first position and the second position, and using the first position, the second position, and the angle of rotation, determine a null space of a matrix. In one example, the matrix is
METHODS AND APPARATUS TO MONITOR AND PREVENT TRAILER SWAY OF A VEHICLE AND TRAILER
Methods and apparatus to prevent trailer sway are disclosed. An example apparatus to prevent trailer sway of a trailer coupled to a vehicle includes prediction circuitry to predict, based on sensor data from one or more sensors of the vehicle, whether a trailer sway condition associated with the vehicle is likely to occur, and control activation circuitry to, in response to the prediction that the trailer sway is likely to occur, activate at least one vehicle control of the vehicle to prevent the trailer sway condition from occurring, the at least one vehicle control to include applying torque to at least one of one or more trailer wheels of the trailer or one or more vehicle wheels of the vehicle.
Vehicle control device
A vehicle control device is configured to control a vehicle. The vehicle control device is capable of deriving a required driving force required for traveling of the vehicle based on an output requirement received from a driver, and controlling a driving force of the vehicle using the required driving force as a target value. The vehicle control device is configured to transition to a second traveling mode when the required driving force increases while the vehicle is traveling in a first traveling mode. The vehicle control device is configured to perform driving force reduction control, in which an amount of increase in the required driving force accompanying an increase in the output requirement is made smaller than an amount of increase in the required driving force in a normal state, at a time of performing transition to the second traveling mode.
