    Abstract: A vehicle travel assistance system includes a travel assistance control unit, an operation unit, and a travel assistance setting unit. The travel assistance control unit is configured to perform travel assistance in a braking-and-driving-force distribution control mode and an automatic cruise control mode. The travel assistance setting unit supplies, to the travel assistance control unit, setting information of travel assistance in response to the received operation under a condition that the operation received by the operation unit is for selecting the braking-and-driving-force distribution control mode, the travel assistance setting unit automatically supplies setting information of the braking-and-driving-force distribution control mode to the travel assistance control unit regardless of the operation in a case where a speed of the vehicle becomes an automatic deactivation speed or higher and thereafter becomes an automatic reactivation speed or lower.

    Abstract: An apparatus and a method for actuating a function of a motor vehicle are provided. The apparatus has a first transmission/reception device arranged at a first location of the motor vehicle and designed to receive a functional signal for actuating a function of the motor vehicle from a functional device different from the motor vehicle and to transmit a first acknowledgement signal, a second transmission/reception device arranged at a second location of the motor vehicle and designed to receive the acknowledgement signal from the first transmission/reception device, a control device in communication with the first transmission/reception device and the second transmission/reception device and designed to measure a propagation time of the first acknowledgement signal from the first transmission/reception device to the second transmission/reception device, to compare same with a predetermined threshold value, and to actuate or disable the function based on the comparison.

    Abstract: A method is for determining a maximum coefficient of friction of a wheel of a vehicle on a road. The method includes: determining a reference wheel acceleration of the wheel, wherein accelerations and a yaw behavior of the wheel and/or of the vehicle on the road are determined, determining a real wheel acceleration of the wheel, wherein a slip behavior of the wheel on the road is determined, comparing the reference wheel acceleration and the real wheel acceleration, in particular forming a quotient, determining the maximum coefficient of friction from the comparison of the reference wheel acceleration and the real wheel acceleration.

    Abstract: A method for controlling propulsion of a heavy-duty vehicle includes. configuring a nominal shaft slip of the drive shaft in dependence of a desired longitudinal wheel force to be generated by the driven axle, wherein a shaft slip is indicative of a difference between a current vehicle velocity and a vehicle velocity corresponding to the rotation speed of the drive shaft, obtaining a rotation speed of the left wheel and a rotation speed of the right wheel, as function of a current shaft slip of the driven axle, estimating a peak shaft slip value associated with an open differential peak longitudinal force of the driven axle, based on the current shaft slip and on the corresponding obtained speeds of the left and right wheels, and controlling propulsion of the heavy-duty vehicle unit by setting the current shaft slip of the drive shaft based on the configured nominal shaft slip adjusted in dependence of the estimated peak shaft slip value.

    Abstract: The technology relates to developing a highly accurate understanding of a vehicle's sensor fields of view in relation to the vehicle itself. A training phase is employed to gather sensor data in various situations and scenarios, and a modeling phase takes such information and identifies self-returns and other signals that should either be excluded from analysis during real-time driving or accounted for to avoid false positives. The result is a sensor field of view model for a particular vehicle, which can be extended to other similar makes and models of that vehicle. This approach enables a vehicle to determine when sensor data is of the vehicle or something else. As a result, the detailed modeling allowing the on-board computing system to make driving decisions and take other actions based on accurate sensor information.

    Abstract: A control system includes a plurality of request generation devices each of which outputs first and second requests based on a request generated by at least one application, an arbitrator that arbitrates the first and second requests and that outputs a single first request and a single second request, and a control apparatus that controls an actuator based on a final request obtained by arbitrating the first and second requests from the arbitrator and a request made by a driver. The arbitrator specifies the request generation device that has output a request corresponding to the final request based on the final request, the self-output first request, and the self-output second request. The request generation device specified by the arbitrator specifies the application that has generated the request corresponding to the final request based on the self-output first request, the self-output second request, and the request made by the driver.

    Abstract: Systems and methods of controlling an active safety feature of a vehicle are provided. The systems and methods receive radar data from a radar device of the vehicle and image data from a camera of the vehicle. Object detection and tracking processes are performed on the radar data and the image data to identify and track objects in an environment of the vehicle. Conditions are assessed with respect to identified objects to ascertain whether a radar track is erroneously reported as a separate object to a camera track. When the conditions are assessed to be true, an object corresponding to the camera track is used as an input for controlling an active safety feature of the vehicle and an object corresponding to the radar track is discounted for controlling the active safety feature of the vehicle.

    Abstract: Aspects of the present disclosure relate to differentiating between active and inactive construction zones. In one example, this may include identifying a construction object associated with a construction zone. The identified construction object may be used to map the area of the construction zone. Detailed map information may then be used to classify the activity of the construction zone. The area of the construction zone and the classification may be added to the detailed map information. Subsequent to adding the construction zone and the classification to the detailed map information, the construction object (or another construction object) may be identified. The location of the construction object may be used to identify the construction zone and classification from the detailed map information. The classification of the classification may be used to operate a vehicle having an autonomous mode.
