LOAD SENSING FOR TRACTOR TRAILERS
In a particular embodiment, a vehicle load measurement system is described that includes a chassis configured to support a body of the vehicle. In this embodiment, the vehicle load measurement system also includes a suspension system and a plurality of angle sensors attached to the suspension system. Each angle sensor is configured to measure an angle with respect to height. In this embodiment, the plurality of angle sensors include a first sensor attached to the first side of the suspension system configured to measure a first angle and a second sensor attached to the second side of the suspension system configured to measure a second angle. According to this embodiment, the first angle and the second angle are combined to obtain a combined value representative of axle load.
Tractor Unit With On-Board Regenerative Braking Energy Storage for Stopover HVAC Operation Without Engine Idle
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 trailer, a tractor-trailer configuration, 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.
SUPPLEMENTAL ELECTRIC DRIVE WITH PRIMARY ENGINE RECOGNITION FOR ELECTRIC DRIVE CONTROLLER ADAPTATION
Through-the-road (TTR) hybrid designs using control strategies such as an equivalent consumption minimization strategy (ECMS) or an adaptive ECMS are implemented at the supplemental torque delivering electrically-powered drive axle (or axles) in a manner that follows operational parameters or computationally estimates states of the primary drivetrain and/or fuel-fed engine, but does not itself participate in control of the fuel-fed engine or primary drivetrain. BSFC type data particular to the paired-with fuel-fed engine allows an ECMS implementation (or other similar control strategy) to adapt to efficiency curves for the particular fuel-fed engine and to improve overall efficiencies of the TTR hybrid configuration.
DRIVER ASSISTANCE FOR A COMBINATION
For driver assistance for a combination (8) with a motor vehicle (9) and a trailer (10), a first camera image (19) and a second camera image (20) are generated. A combined image (21) is generated by means of a computing unit (13) by superimposing the camera images (19, 20) such that the second camera image (20) covers a subsection of the first camera image (19), wherein a hitch angle (14) of the combination (8) is determined by means of the computing unit (13). State data of the combination (8) are determined by means of a sensor system (17) and it is determined whether the combination (8) moves forward or backward. The hitch angle (14) is determined based on the state data, if the combination (8) moves forward and based on a change of time-dependent image data, if the combination moves backward. A position of the subsection is determined depending on the hitch angle (14).
Semi-trailer, semi-trailer truck and method for braking a semi-trailer
A semitrailer includes a wheel and an electric machine for driving the wheel, wherein the electric machine is configured so as to be operable as an electromotive brake in a braking state.
SYSTEM AND METHOD FOR IDENTIFYING A CHANGE IN LOAD OF A COMMERCIAL VEHICLE
A system for identifying a change in a load of a commercial vehicle, the commercial vehicle including an electronic stability program with at least one inertial sensor and a control unit for estimating a mass of the commercial vehicle and/or the load, including: a device for querying sensor data of the at least one inertial sensor; and an evaluation unit which is configured to identify the load change if the queried sensor data exceed a variation range, and inform the control unit of the identified load change to allow the load change to be taken into account in the estimation of the mass. Also described are a related commercial vehicle, method, and computer readable medium.
Axle Unit
The present invention relates to an axle unit comprising an axle tube and an axle stub, wherein the axle stub is formed to be rotationally symmetrical with respect to a stub axis in some regions and has a channel which extends substantially parallel to the stub axis, wherein the axle stub has a first connection portion which has an engagement geometry for fluid-tight connection to the channel, wherein the axle tube is formed to be substantially rotationally symmetrical about a tube axis and wherein the axle tube and the axle stub are fixed on/to one another by way of a cross-member in such a way that the tube axis and the stub axis are spaced from one another.
SPACE-EXPANDABLE AND EASILY TRANSPORTABLE CARAVAN
The space-expandable and easily transportable caravan according to present invention is a cubical caravan, wherein the caravan has a structure in which both sides expand symmetrically, characterized by: comprising a caravan (100) which has a cubical upper main body (110) having space expandable and collapsible panel unit and a lower main body carrier (120) integrally attached thereunder to support the upper main body (110); the space expandable and collapsible panel unit is expandable from sides comprising external panels (10a, 10b) and internal panels (20a, 20b) on each of side walls of the caravan, wherein each external panel (10a, 10b) comprises roof panel (11a, 11b) which forms an expansion roof by spreading it outwards, and expansion external panel (12a, 12b) which forms an expanded side outer wall, and each of the internal panel (20a, 20b) comprises floor panel (21a, 21b) which forms an expansion floor by spreading it downwards, and expansion side panel (22a and 23a, 22b and 23b) which forms the front and back expanded outer wall. The space-expandable caravan (100) of present invention can be set up by conveniently loading onto a cargo box of a truck by lifting the caravan using four jacks, and easily unloading from the cargo box to a desired place.
SYSTEM AND METHOD OF CAPACITANCE CONTROL
A system and method of capacitance management in an agricultural vehicle and connected implement, wherein the vehicle and implement have a plurality of electric drives connected to a common connection and connectable to a direct current supply, and each electric drive has an associated Y capacitor between each direct current supply connection and the common connection, wherein the method includes receiving and summing capacitance values for each of the electric drives and comparing with a stored threshold value. If the threshold value is exceeded, a sequence of selective disconnections of individual electric drives is performed until the sum of the received capacitance values is less than or equal to the threshold value. The method may be performed manually, or automatically based on a sequence defined in a priority list until the sum of the received capacitance values is less than or equal to the threshold value.
Systems and Methods to Address Jackknifing in Autonomous Vehicles
The technology relates to articulated autonomous vehicles that can potentially jackknife. To avoid or mitigate such hazardous conditions, the current state of the vehicle is evaluated against the vehicle's planned trajectory, for instance as it drives along a freeway or surface streets. When the evaluation indicates a likelihood of jackknifing, an automated braking approach is implemented using elective braking to stabilize the vehicle. The braking approach can depend on whether the situation involves tractor jackknifing or trailer jackknifing, and one or more different braking mechanisms can be employed for a selective modulation of the braking profile to address actual jackknifing or to prevent the vehicle from entering a jackknifing situation.
