The disclosure generally pertains to systems and methods for assisting a driver to travel through a drive-through lane of an establishment in an autonomous mode of operation. In an example method, a processor in a vehicle determines a location of the vehicle in a drive-through lane in various ways such as, for example, based on objects located in the vicinity of the drive-through lane, based on location coordinates, and/or based on a geofence defined around the establishment. The processor may then place the vehicle in an autonomous mode of operation and instruct the driver of the vehicle to refrain from touching vehicle driving control components such as the steering wheel, the brake pedal, and the accelerator pedal. The vehicle autonomously then moves through the drive-through lane in a stop-and-go mode of movement at a controlled speed while executing lane-centering and collision avoidance.

Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method selects one or more electric machines to start an engine. The method may reference a data structure, such as a matrix or table, and the matrix or table outputs which of the one or more electric machines is applied to start the engine.

Various embodiments include a method for controlling a motor vehicle having an internal combustion engine with a crankshaft and a drivetrain separable from the internal combustion engine using a releasable clutch comprising: propelling the vehicle in a first operating state in a predetermined range around a speed while the internal combustion engine is off and is separated from the drivetrain by the releasable clutch; sensing a braking operation while in the first operating state; predicting whether a power demand is expected within a predetermined time interval; and, if the power demand is expected, setting the crankshaft of the internal combustion engine in rotation, or increasing a rotational speed of the crankshaft in preparation for an engine restart.

The present disclosure relates to a pull up controlling system of a vehicle for controlling the vehicle in a planned stop-and-go situation. The pull up controlling system determines a position of the vehicle and identifies a stop-and-go destination within a predeterminable distance from the vehicle position. The stop-and-go destination includes an interaction interface. The pull up controlling system provides a user input request relating to whether to discard or acknowledge the stop-and-go destination. The pull up controlling system receives intention data indicative of confirmation to acknowledge the stop-and-go destination. The pull up controlling system further derives preference data indicative of an openable section of the vehicle. The pull up controlling system maneuvers the vehicle to pull up at the stop-and-go destination, with the openable section aligned with the interaction interface.

A method of reducing cold start emissions in a series mode hybrid electric vehicle, including an internal combustion engine with an exhaust duct having a catalyst and a downstream oxygen sensor, an output of the combustion engine being connected to an electric generator with a power output of at least 10 kW that is connected to an electric motor which is coupled to a drive shaft of two or more wheels. The method includes detecting a cold start condition, injecting fuel into the engine such that combustion at a lambda value, λ, is achieved for which λ>1, running the engine at a speed of 1000 rpm or higher, determining if the efficiency of the catalyst reaches a first level, setting λ to about 1 after the predetermined efficiency level of the catalyst has been reached, and reducing the speed to working conditions when the catalyst efficiency reaches a second level.

A control apparatus includes: a rotor temperature estimation unit estimating a temperature of a rotor based on stator temperature information from a first temperature sensor for identifying a temperature of a stator, refrigerant temperature information from a second temperature sensor for identifying a temperature of refrigerant used to cool an electric motor, and rotation speed information about the rotor from a resolver for identifying a rotation speed of the rotor; and an electric motor control unit controlling at least one of an output characteristic and a drive condition of the electric motor based on the temperature of the rotor estimated by the rotor temperature estimation unit.

Systems and methods for controlling navigation of an autonomous vehicle through an intersection are disclosed. The methods include determining a loiter pose of an autonomous vehicle for stopping at a point within the intersection before initiating an unprotected turn for traversing the intersection. One or more distinct classes of trajectories are then identified, each of which is associated with multiple trajectories that take the same combination of discrete actions with respect to the loiter pose. A constraint set for each of the one or more distinct classes of trajectories is then be computed based on the loiter pose, and a candidate trajectory is determined for each of the one or more distinct classes based on the corresponding constraint set. A trajectory for the autonomous vehicle for executing the unprotected turn for traversing the intersection is selected from amongst the candidate trajectories.

A control method for a self-driving vehicle provided with an engine as a driving source, comprising: determining whether or not coast stop is executed in accordance with required driving force of the vehicle, the coast stop being for automatically stopping the engine during the vehicle traveling at speed not more than predetermined vehicle speed; setting the required driving force so that an intervehicular distance between the host vehicle and a preceding vehicle becomes closer to a predetermined distance under presence of the preceding vehicle in front of the host vehicle; predicting a behavior of the preceding vehicle from a situation in front of the preceding vehicle under presence of the preceding vehicle; and prohibiting release of the coast stop for the engine during an automatic stop when future deceleration of the preceding vehicle is predicted in response to an expansion of the intervehicular distance.

A vehicle controlling apparatus includes an engine processor, an electric motor, an electric power storage, an SOC detector, an internal resistance detector, and a resistance threshold setting unit. The engine processor is configured to stop an engine of a vehicle on the basis of a stop condition, and start the engine on the basis of a start condition. The engine processor is configured to prohibit a stop of the engine based on the stop condition based on determining that an internal resistance of the electric power storage detected by the internal resistance detector is equal to or greater than a resistance threshold set by the resistance threshold setting unit on the basis of a state of charge of the electric power storage, and permit the stop of the engine based on determining that the internal resistance is less than the resistance threshold.
