Presenting geographic search results using location projection and time windows
Users within transit in a vehicle may initiate location queries to fulfill a set of interests, such as stops for food, fuel, and lodging. A device may fulfill the queries according to various factors, such as the distance of nearby locations to the user or to another location specified by the user, and the popularity of various locations. However, the user may not have specified or even chosen a route, and may wish to have interests fulfilled at a later time (e.g., stopping for food in 30 minutes), and a presentation of search results near the user's current location may be unhelpful. Presented herein are techniques for fulfilling location queries that involve predicting a route of the user, and identifying a timing window for the query results (e.g., locations that are likely to be near the user's projected location when the wishes to stop for food in 30 minutes).
TRAFFIC OBSTRUCTION DETECTION
One or more techniques and/or systems are provided for training and/or utilizing a traffic obstruction identification model for identifying traffic obstructions based upon vehicle location point data. For example, a training dataset, comprising sample vehicle location points (e.g., global positioning system location points of vehicles) and traffic obstruction identification labels (e.g., locations of known traffic obstructions such as stop signs, crosswalks, stop lights, etc.), may be evaluated to extract a set of training features indicative of traffic flow patterns. The set of training features and the traffic obstruction identification labels may be used to train a traffic obstruction identification model to create a trained traffic obstruction identification model. The trained traffic obstruction identification model may be used to determine whether a road segment has a traffic obstruction or not.
PROVIDING USERS WITH ACCESS TO ROUTES FOR TRAVELING
Among other things, one or more techniques and/or systems are provided for providing users with access to a route for travelling. A user, of a client device, may send a request for access to the route to a route planning service. The route may correspond to a starting location and an ending location. The route planning service may query a route database to identify an entry indicating that a restricted access road segment (e.g., a high occupancy vehicle lane, a shoulder lane, a bus lane, etc.) and/or a road segment (e.g., comprising a traffic light alteration capability) exists between the starting location and the ending location. Responsive to successfully authorizing the user for travelling the restricted access road segment and/or the road segment, the route, comprising the restricted access road segment and/or the road segment, may be provided to the client device.

LAUNCH CONTROL
A launch control system launches a vehicle from a slowed speed or stopped condition, to an accelerated speed. The system is activated by operating a switch while the vehicle is stopped. An acceleration pedal is depressed while an up shifter paddle and down shifter paddle are being held in a shifting position. The system launches the vehicle when the up shifter paddle and the down shifter paddle are simultaneously moved to a non-shifting position. The system automatically switches gears during the launch so as to increase the speed of the vehicle. The system is activated until the speed of the vehicle reaches a speed associated with the amount the accelerated pedal is depressed. The system may further inhibit yaw rotation of the vehicle during launch by moderating a rotation rate of the vehicle engine.
CONDITION-BASED LANE SUGGESTIONS FOR TRAVEL ADVISING
Users who are traveling on a path between a first location and a second location may be informed by navigation devices about the user's selected route. The path may also feature two or more lanes, which may present comparative advantages (e.g., a toll-restricted lane may present less traffic, and a toll-free lane may present more traffic at a reduced cost). Presented herein are techniques for enabling navigation devices to advise users about the lanes of the path. A travel service may collect information about the respective lanes, such as traffic density and the typical travel duration of users utilizing the lane during various periods, and may transmit information about the predicted travel durations of the respective lanes to the device. Such information may enable the device to advise the user to choose a selected lane, according to the predicted travel durations of the lanes of the path.

Responsive to successfully authorizing the user for travelling the restricted access road segment and/or the road segment, the route, comprising the restricted access road segment and/or the road segment, may be provided to the client device.
DRIVING PROFILES FOR AUTONOMOUS VEHICLES
One or more techniques and/or systems are provided for operating an autonomous vehicle based upon a driving preference. For example, a driving profile, comprising a driving preference (e.g., a speed preference, a route preference, etc.) of a user, may be provided to an automated driving component of the autonomous vehicle. An operational parameter for the autonomous vehicle may be generated based upon the driving preference of the user. The autonomous vehicle may be operated based upon the operational parameter. In an example, a condition of the user traveling in the autonomous vehicle may be determined, and the operational parameter for the autonomous vehicle may be adjusted based upon the condition of the user not corresponding to the driving preference.

Users who are traveling on a path between a first location and a second location may be informed by navigation devices about the user's selected route. The path may also feature two or more lanes, which may present comparative advantages (e.g., a toll-restricted lane may present less traffic, and a toll-free lane may present more traffic at a reduced cost).

Such information may enable the device to advise the user to choose a selected lane, according to the predicted travel durations of the lanes of the path.
Method of decoupling input and output torque for engine speed control and hybrid powertrain utilizing same
A method of decoupling output torque from input torque during engine speed control of a hybrid powertrain for a vehicle comprises determining, via a controller, a virtual output torque required on an output member of a multi-mode transmission given a virtual input torque commanded on an input member of the multi-mode transmission for engine speed control in a selected mode of the multi-mode transmission such that rotational speed of the output member is unchanged to prevent undesired torque variation at the output member. The controller determines the virtual output torque via a first stored transfer function relating virtual output torque to virtual input torque based on modeled physical dynamics of the vehicle driveline for the selected mode of the multi-mode transmission. A hybrid powertrain includes an engine and a hybrid transmission, and a controller that controls the hybrid transmission according to the method.
