Abstract: The disclosure is directed at an apparatus, method and computer readable medium for a self-powered towed vehicle in a road train or tractor-trailer vehicle configuration to detect and respond to forward jack-knifing risk conditions. The apparatus may detect jack-knifing risk conditions based on sensors and information including sensors to detect an angle of misalignment between the towed vehicle and the vehicle directly in front of it in the road train. The apparatus may respond to the presence of a jack-knifing risk condition by reducing or eliminating the motive rotational force applied to the wheels of the towed vehicle.

Abstract: The disclosure is directed at an apparatus for an active converter dolly for use in a tractor-trailer configuration. In one aspect, the apparatus includes a system to connect a first trailer towed behind a towing vehicle to a second trailer. The apparatus further includes a kinetic energy recovery device for translating the mechanical motions or actions of the dolly into electricity or electrical energy so that this energy can be used to charge a battery or to power other functionality for either the dolly or the tractor-trailer. The active dolly may also operate to assist in shunting the tractor-trailer. The active dolly is operable in a number of modes to increase vehicle performance and efficiency.

Abstract: The present disclosure relates to a method for controlling steering of a vehicle arrangement. The method is controlling steering of the vehicle arrangement during a turning maneuver, by applying a differential wheel speed by at least one of individually controllable electric machines and reducing the operational capacity of a power steering system, when a first power utilization value, obtained by operating the individually controllable electric machines with the differential wheel speed, is equal to, or greater than a second power utilization value, obtained by operating the power steering system during the turning maneuver.

Abstract: A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.
