A method that may include receiving driving information and environmental metadata indicative of information sensed by the vehicle; detecting multiple driving events encountered during the driving over the path; determining driving events; for each driving event, determining a comfort based autonomous driving pattern information; for each driving event, determining an driving event identifier; and storing in at least one data structure a driving event identifier for each one of the multiple types of driving events, and a comfort based autonomous driving pattern information.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

A method for selecting and executing at least one reactive action of a vehicle includes a control unit receiving sensor data from a vehicle sensor system; detecting an emergency situation based on the sensor data; performing an evaluation; and selecting and implementing a reactive action for minimizing an accident risk of the vehicle based on the evaluation, where, in the evaluation, sensors that are uninvolved in the detection of the emergency situation are not taken into account or are taken into account at a lower weighting, are operated at a reduced performance, and/or are operated with a reduced scanning range. In addition, a control unit, computer program, and machine-readable memory medium can be provided for implementing the method.

A voltage controlled aircraft electric propulsion system includes an electric propulsion system. The voltage controlled aircraft electric propulsion system may include electric propulsors providing thrust for the aircraft. In hybrid systems, a gas turbine engine may also be included. The electric propulsion system may include at least one electric generator power source, at least one propulsor motor load, and at least one stored energy power source, such as a battery. The propulsor motor load may be supplied power from a power supply bus. The voltage of the power supply bus may be adjusted according to an altitude of the aircraft while maintaining a substantially constant current flow to the propulsor motor load. Due to the adjustment to lower voltages at increased altitude, insulations levels may be lower.

Systems, apparatus and methods may be configured to implement actively-controlled light emission from a robotic vehicle. A light emitter(s) of the robotic vehicle may be configurable to indicate a direction of travel of the robotic vehicle and/or display information (e.g., a greeting, a notice, a message, a graphic, passenger/customer/client content, vehicle livery, customized livery) using one or more colors of emitted light (e.g., orange for a first direction and purple for a second direction), one or more sequences of emitted light (e.g., a moving image/graphic), or positions of light emitter(s) on the robotic vehicle (e.g., symmetrically positioned light emitters). The robotic vehicle may not have a front or a back (e.g., a trunk/a hood) and may be configured to travel bi-directionally, in a first direction or a second direction (e.g., opposite the first direction), with the direction of travel being indicated by one or more of the light emitters.

Systems for hybrid electric engines have a fuel vapor canister (FVC) in fluid communication with (i) fuel vapor in a fuel tank with a refueling valve therebetween, (ii) an intake manifold with a canister purge valve therebetween, and (iii) atmospheric pressure (atm) with a canister vent valve (CVV) therebetween, a bypass loop around the refueling valve, and a pressure sensor upstream of both the refueling valve and the CVV. The loop has a control pump and a control valve controlling fluid communication with atm, and in a first mode, control valve and CVV open, pumps fuel vapor to the FVC for pressure control, then closes the control valve; in a second mode, control valve closed and CVV open, pumps atm to the FVC; and in a third mode, control valve and CVV open, pumps fuel vapor to the FVC to a pre-selected threshold to close the CVV.

Vision based guidance system and method for lawn mowing devices are disclosed. An exemplary method for operating an autonomous lawn mower includes receiving, via a receiver, a perimeter data set from a handheld computer. The perimeter data set includes a perimeter outline of at least one perimeter that is determined utilizing a GPS unit of the handheld computer. The exemplary method also includes collecting, via at least one camera, images of a set area within the perimeter outline and mowing, via a mowing blade, grass within the set area. The exemplary method also includes autonomously steering, via a controller, the autonomous lawn mower based on the perimeter outline of the at least one perimeter and the images captured by the at least one camera.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis and positioned rearward of the cab, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A vehicular collision avoidance system includes a forward-viewing camera, a rearward-viewing camera, a rearward-sensing non-vision sensor and an electronic control unit. The vehicular collision avoidance system detects vehicles present forward and/or rearward of the equipped vehicle. Responsive to at least one selected from the group consisting of (i) data processing of image data captured by the rearward-viewing camera and (ii) data processing of sensor data captured by the rearward-sensing non-vision sensor, the vehicular collision avoidance system detects another vehicle approaching the equipped vehicle from the rear, determines that the other vehicle is traveling in the same traffic lane as the equipped vehicle, determines speed difference between the vehicles, and determines distance from the equipped vehicle to the other vehicle. Based on such determinations, the system determines that impact with the equipped vehicle by the other vehicle is imminent.

A method of controlling stability of a vehicle and a stability control system for the vehicle. A driver command is determined based on driver input data. At least one output command is sent to one or more vehicle systems to control stability of the vehicle based on the driver command. A controller sends the output command based on a control hierarchy that provides an order in which the controller controls body motion of the vehicle, wheel slip of the vehicle, and standard stability of the vehicle to control stability of the vehicle. The order dictates that the controller controls the body motion of the vehicle and the wheel slip of the vehicle before the controller controls the standard stability of the vehicle. A state of one or more of the vehicle systems is controlled based on the sent output command as dictated via the control hierarchy.
