A zero emissions electrically powered haul truck is disclosed. The haul truck has a 40 metric ton hauling capacity and a form factor that allows the truck to travel through underground mines. The truck also includes a primary battery assembly that is externally mounted along the front and sides of the truck.

An onboard hazard detection system for installing on a vehicle includes a processor that is configured to receive sensed data that is acquired by one or more sensors that are installed on the vehicle and that are configured to sense a topography of a region in the vicinity of the vehicle. The received data is analyzed to generate a three-dimensional map of the region based on the sensed data. One or more characteristics of an approach of the vehicle toward a cliff or safety barrier is calculated, based on the sensed data. The system detects when the calculated characteristics are indicative of a hazard and performs an action.

A method of controlling a differential lock. The differential lock is actuated to lock a differential assembly when wheel slip of a first wheel assembly is detected and a duration of the wheel slip exceeds a pre-activation buffer. The pre-activation buffer is based on acceleration of the first wheel assembly and vehicle speed.

A system for retaining a plurality of compressed gas cannisters for fueling a vehicle is provided, the system comprising: a base which includes: a plate including a distal end and a proximal end; a base engagement member at the distal end of the plate; and a first mating member proximate the proximal end; a cassette which includes: a top; a first side; a second side; a front; a back; a bottom to define an interior, the interior for housing the plurality of compressed gas cannisters; at least one fork pocket mounted on one of the top, the bottom or the back, the fork pocket extending from a distal end a distance; a plurality of gas cannister apertures extending between the interior and an ambient environment, wherein the bottom includes a bottom engagement member which extends outward beyond the first side at the distal end; a locking mechanism proximate the distal end; and a second mating member proximate a proximal end, wherein the first mating member and the second mating member are in pivotal engagement in use.

A method of brake management in a heavy vehicle is provided, and includes, in response to determining that a request for emergency braking is imminent, increasing an air pressure of e.g., a service brake system of the vehicle and decreasing an air pressure of e.g., a parking brake system of the vehicle. The method further includes, in response to actually receiving the request for emergency braking of the vehicle, performing an emergency braking of the vehicle by compounding both the service and parking brake systems, including further increasing the air pressure of the service brake system and further decreasing the air pressure of the parking brake system. A corresponding brake system controller, brake system, heavy vehicle, computer program and computer program product are also provided.

The vehicle system can include: a set of vehicle couplings (e.g., a tractor interface, a trailer interface, etc.); a chassis, a battery pack, an electric powertrain, a sensor suite, and a controller. The modular vehicle system can optionally include landing gear, a suspension, and any other suitable set of components. The vehicle system functions to structurally support and/or tow a trailer – such as a Class 8 semi-trailer – and/or to augment/supplement a tractor propulsive capability (e.g., via a diesel/combustion engine) with a supplementary electric drive axle(s).

A transport refrigeration unit (TRU) system (IO) is provided. The TRU system includes a TRU (30), an electrical grid and a control unit. The TRU (30) is configured to be operably coupled a container (20) and includes components configured to control an environment within an interior of the container (20) and a TRU battery pack (40) configured to store energy for powering at least the components. The control unit is communicative with the TRU (30) and the electrical grid and is configured to manage power supplies and demands between the TRU battery pack (40) of each TRU (30) and the electrical grid.

An electrified vehicle includes a chassis, a body, and a cab. The chassis is configured to support a tractive element. The chassis includes a battery box. The body is supported by the chassis. The cab is supported by the chassis. The battery box includes a shell defining an internal cavity. The battery box is configured to receive a module. The module comprises a battery and a module terminal. The battery box is configured to transfer energy from the module to a component of the vehicle. The internal cavity of the battery box comprises a system terminal configured to contact the module terminal of the module to facilitate the transfer of the energy from the module to a component of the vehicle.

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.
