Autonomy first route optimization for autonomous vehicles
Embodiments herein can determine an optimal route for an autonomous electric vehicle. The system may score viable routes between the start and end locations of a trip using a numeric or other scale that denotes how viable the route is for autonomy. The score is adjusted using a variety of factors where a learning process leverages both offline and online data. The scored routes are not based simply on the shortest distance between the start and end points but determine the best route based on the driving context for the vehicle and the user.

METHOD FOR CONTROLLING A MOTOR VEHICLE IN EMERGENCY STEERING MODE BY MEANS OF FRONT WHEEL BRAKE-BASED TORQUE VECTORING
A method can be used to control a steer-by-wire steering system in an emergency steering mode. The method comprises checking a steering system for the presence of a fault state and upon detection of a fault implementing the emergency steering mode, which involves determining a setpoint position of a steering tie rod using a setpoint wheel steering angle, determining a front wheel to be braked and a brake pressure to attain the setpoint position with a control unit, transmitting the front wheel to be braked and the brake pressure to a brake system, braking the front wheel to be braked, and increasing a torque provided by a wheel drive to compensate for a loss of speed of the motor vehicle caused by the braking of the front wheel to be braked.

METHOD FOR GENERATING A REFERENCE TRAJECTORY WITHIN A LANE, METHOD FOR OPERATING A VEHICLE, DATA PROCESSING APPARATUS, VEHICLE, AND COMPUTER-READABLE MEDIUM
The disclosure relates to a method for generating a reference trajectory within a lane for a vehicle. The method comprises receiving at least one vehicle current state parameter describing a current state of the vehicle (S11). The current state of the vehicle comprises at least a current position of the vehicle. Furthermore, a destination parameter describing a destination to be reached by the vehicle (S12), and at least one route parameter describing a route for reaching the destination (S13) are received. Moreover, the method comprises estimating a power loss being caused when traveling from the current position of the vehicle to the destination (S14). The reference trajectory within the lane is determined such that it minimizes the power loss and leads to the destination (S15). Additionally, a method for operating a vehicle is presented. According to this method, a reference trajectory is generated in accordance with the above method (S21) and at least one control signal is provided for controlling a motion of the vehicle along the reference trajectory (S22). Furthermore, a data processing apparatus, a vehicle and a computer-readable medium are presented.

VEHICULAR TRAILERING GUIDANCE SYSTEM
A vehicular trailer guidance system includes an electronic control unit (ECU) and a rear backup camera disposed at a vehicle. A human machine interface (HMI) is operable in (i) a trailer left-backup mode, (i) a trailer straight-backup mode and (iii) a trailer right-backup mode. Responsive to selection by the driver of the trailer left-backup mode or trailer right-backup mode, the ECU sets a desired trailer angle of the trailer tongue leftward or rightward to an angle that is commensurate with a driver-selected setting of an input device. Responsive to selection by the driver of the trailer straight-backup mode, the ECU sets the desired trailer angle to a zero degree angle. The ECU, while the vehicle is backing up the trailer, controls the power steering system of the vehicle to steer the vehicle to back up the trailer to have the determined trailer angle coincide with the set desired trailer angle.

CONTROLLING MOTION OF A VEHICLE
A method for controlling motion of a vehicle, the method comprising the steps of: obtaining input information on a vector related to the velocity of said vehicle; computing repeatably a future trajectory of said vehicle based on said input information and trial torques to be applied to at least one wheel of said vehicle for optimizing said future trajectory in view of a target vehicle motion, thereby obtaining target trial torques; and applying the obtained target trial torques to the at least one wheel for controlling the motion of said vehicle.
METHOD FOR PROVIDING AN AT LEAST PARTIALLY AUTOMATIC DRIVING FUNCTION AND/OR A PERSONALIZED FUNCTION IN A MOTOR VEHICLE
An example method of providing an at least partially automatic driving function and/or a personalized function in a motor vehicle as well as to the motor vehicle may include establishing a communication link between a communication interface of the motor vehicle and a communication interface of a mobile terminal, which is associated with a user of the motor vehicle; receiving terminal data transferred via the communication link in the motor vehicle, which is recorded on the mobile terminal and which describes at least navigation information and/or user information relating to the user; and providing an at least partially automatic driving function of a driver assistance system of the motor vehicle and/or a personalized function in the motor vehicle by evaluating the received terminal data.
