Abstract: A method, autonomous system controller, and computer program product generate a first route for an autonomous vehicle to transport a first person from a first location to a destination. In response to determining that a second person satisfies trigger criteria comprising: (i) being at a second location that is within a proximity threshold to the first route; (ii) being associated with the first person; and (iii) being associated with the destination, an affordance is caused to be presented via respective user interface devices to at least one of the first and second persons that proposes that the autonomous vehicle transport both the first and second persons to the destination. In response to receiving acceptance, a second route is generated for the autonomous vehicle that comprises picking up the first person at the first location, picking up the second person at the second location, and transporting both persons to the destination.

Abstract: Among other things, an operation of a computational device in identifying a type of a given trip of a person is improved. Historical information is stored about prior trips of the person or of other people or both. The historical information is based on other than recorded motion data of the trips. Features are derived about the prior trips from the historical information. Features indicative of the type of the given trip are identified by the computational device. The type of the given trip is identified based on the features derived from the historical information.
Abstract: A historical task database relating vehicle rollout decisions, vehicle maintenance states and subsequent deteriorations is created. A pattern analyzer may use an item-set mining algorithm on the task database to recommend whether a vehicle with its current maintenance state should be deployed. A supervisor uses this recommendation to make a rollout decision. These decisions are added to the database. Heuristic rules are defined to determine if the rollout decision was correct. The system to learns when a supervisor continues to make costly rollout errors. The system also discovers combinations of defects that lead to a rapid deterioration and makes recommendations that the vehicle be sent for maintenance rather than being rolled out.

Abstract: If the destination has not been input, it is judged whether the present location is on the expressway (step S32). If the judgement result of the step S32 is positive, it is judged whether or not the actual SOC is less than or equal to the threshold TH2 (step S34). If the judgement result of the step S34 is positive, the restoring control is executed (step S36). Subsequent to the step S34 or S36, it is judged whether or not the vehicle is still on the expressway (step S38). If the judgement result of the step S38 is positive, it is judged whether or not the actual SOC is greater than or equal to the SOC_T2 (step S42). If the judgement result of the step S42 is positive, the maintaining control is executed (step S44).

Abstract: A damping force control device 10 comprises vary damping shock absorbers, a detector, and a controller. Each of the shock absorbers sets damping coefficient from a minimum value to a maximum value in order to adjust damping force. The detector detects vertical vibration state quantity relating to vibration of the sprung mass. The controller performs an ordinary control for setting the damping coefficient based on the vertical vibration state quantity and according to a predetermined control law suitable for an assumption that all of the wheels touch ground. The controller performs, when at least one of the wheels is an ungrounded wheel which does not touch the ground and each of the other wheels is a grounded wheel which touches the ground, a specific control for setting the damping coefficient of the shock absorber corresponding to the grounded wheel to a first specific value greater than the minimum value.
