Methods and systems for keeping remote assistance operators alert
Examples described may enable provision of remote assistance for an autonomous vehicle. An example method includes a computing system operating by default in a first mode and periodically transitioning from operation in the first mode to operation in a second mode. In the first mode, the system may receive environment data provided by the vehicle and representing object(s) having a detection confidence below a threshold, where the detection confidence is indicative of a likelihood of correct identification of the object(s), and responsive to the object(s) having a confidence below the threshold, provide remote assistance data comprising an instruction to control the vehicle and/or a correct identification of the object(s). In the second mode, the system may trigger user interface display of remote assistor alertness data based on pre-stored data related to an environment in which the pre-stored data was acquired, and receive a response relating to the alertness data.

Method and system for propelling a vehicle
The invention relates to a method for propelling a vehicle comprising a first power source being an internal combustion engine and a second power source comprising at least one electrical machine. The vehicle is configured to be selectively driven according to a first mode and a second mode, wherein said second mode is prioritized more in relation to fuel efficiency of said vehicle than said first mode. When a maximum power for propelling said vehicle is requested, power delivered by said first power source and said second power source is controlled such that the total power delivered by said first and said second power source exceeds the maximum deliverable power of said first power source. The total power delivered by said first and said second power source is allowed to exceed the maximum deliverable power of said first power source when said vehicle is driven according to said second mode.

Vehicle control system
A vehicle travel control device executes vehicle travel control such that a vehicle follows a target trajectory. An automated driving control device generates a first target trajectory that is the target trajectory for automated driving of the vehicle. The vehicle travel control device further determines whether or not an activation condition of travel assist control is satisfied. When the activation condition is satisfied, the vehicle travel control device generates a second target trajectory that is the target trajectory for the travel assist control. When the second target trajectory is generated during the automated driving, the vehicle travel control device determines whether or not a cancellation condition is satisfied. When the cancellation condition is satisfied, the vehicle travel control device cancels both the first target trajectory and the second target trajectory, and decelerates the vehicle.

Counter-rotating electric motor system for high efficiency operation of a hybrid or electric vehicle
A vehicle that utilizes a counter-rotating electric motor to generate at least a portion of its propulsive force that includes the vehicle with front and rear wheels, the counter-rotating motor with two oppositely rotating components linked to two drive shafts that are coupled to the wheels in a common rotational direction, a component for reversible stopping the rotation of at least one rotating component while permitting the drive shafts to rotate, a power source linked to the motor, and a controller that controls both the speed of the vehicle and the reversible stopping component to switch between a first operational mode for slower vehicle speeds and a second operational mode for higher vehicle speeds, thereby increasing the overall electrical efficiency for operating the vehicle.
