摘要： A vehicle driving control method with optimal efficiency includes a first step of state variable modeling of a longitudinal dynamics equation of a vehicle based on a velocity-related state variable and a wheel drive input variable, a second step of calculating wheel power using the state variable and the input variable, a third step of calculating battery power using the wheel power calculation, a fourth step of approximating the battery power, and a fifth step of outputting a wheel drive control target by calculating a minimum solution by using the approximated battery power as an objective function and applying at least one constraint to the objective function.

摘要： This application discloses a vehicle motion status identification method and apparatus, and relates to the field of autonomous driving. In this method, a traveling track of another vehicle may be predicted based on location information and motion information of the another vehicle, and at least two types of the following: lane information of a lane in which the another vehicle is located, lane information of a first adjacent lane of the lane in which the another vehicle is located, and lane information of a second adjacent lane of the lane in which the another vehicle is located, to obtain at least two predicted traveling tracks corresponding to the foregoing at least two types of lane information. Then, a motion status of the another vehicle relative to an ego vehicle may be identified based on the foregoing at least two predicted traveling tracks and lane information of a lane in which the ego vehicle is located, so that sensitivity to instantaneous kinematic information of the another vehicle can be effectively reduced and misidentification of the motion status of the another vehicle can be reduced in monitoring the motion status of the another vehicle relative to the ego vehicle.

摘要： According to various embodiments, systems, methods, and media for evaluating an open space planner in an autonomous vehicle are disclosed. In one embodiment, an exemplary method includes receiving, at a profiling application, a record file recorded by the ADV while driving in an open space using the open space planner, and a configuration file specifying parameters of the ADV; extracting planning messages and prediction messages from the record file, each extracted message being associated with the open space planner. The method further includes generating features from the planning message and the prediction messages in view of the specified parameters of the ADV; and calculating statistical metrics from the features. The statistical metrics are then provided to an automatic tuning framework for tuning the open space planner. An open space is an area without traffic lanes like a parking lot.

摘要： A cruise control method and system, and a vehicle, the method being applicable to a first vehicle (401). When the first vehicle (401) is driving in a first lane (4011), before the first vehicle (401) enters from the first lane(4011) into a preset recognition region (403) to thereby complete vehicle identity recognition in the preset recognition region (403), the cut-in probability of a second vehicle (402) cutting into the first lane (4011) can be predicted according to a movement parameter of the second vehicle (402) that is in an adjacent second lane (402 1), and it is determined, according to the cut-in probability and the stopping time of the first vehicle(401), whether to brake to stop the first vehicle (401); therefore, during the process of controlling the first vehicle(401) to pass through the preset recognition region(403), the driver is not required to temporarily take over control of the first vehicle (401), thus improving the driving experience for the driver, being able to effectively prevent economic loss or potential safety risks for the driver caused by the second vehicle(402) in the adjacent lane cutting in, reducing the costs of self-driving and improving the safety thereof.

摘要： Provided are lane recognition apparatuses and methods including a sensor provided at a vehicle to detect a left line and a right line of a current lane, sense a left line distance and right line distance from a middle of the vehicle to the left line and right line, respectively, and a controller configured to set a sum of the left line distance and the right line distance as a lane width, when the sensor detects both the left line and the right line, correct the left line distance or the right line distance based on a previously set lane width, when the sensor detects one of the left line or the right line, and determine a moving state of the vehicle as any one of normal, left-biased, right-biased, or lane change driving state based on the left line and the right line of the current lane.

摘要： A system (1) for estimating an articulation angle (α) between a first (110) and a second (120) connected vehicle section of an articulated vehicle combination (100), the system comprising:
- a primary image obtaining device (2) configured to be mounted on a first position of one of the vehicle sections and to obtain images of the other vehicle section during use;
- a secondary image obtaining device (3) configured to be mounted on a second position of one of the vehicle sections and to obtain images of the other vehicle section during use, the second position being different from the first position, and/or a mounting orientation at the second position of the second image obtaining device being different from a mounting orientation at the first position of the primary image obtaining device; and
wherein the system is configured to:
- estimate the articulation angle by use of at least one obtained image from the primary image obtaining device;
- determine if an unreliability condition has been fulfilled which indicates that the articulation angle cannot be reliably estimated from the at least one obtained image from the primary image obtaining device; and
when the unreliability condition has been fulfilled, the system is further configured to:
- estimate the articulation angle by use of at least one obtained image from the secondary image obtaining device. -
