Abstract:
A vehicle arrangement includes a tow vehicle (12) and a towed vehicle (10). The towed vehicle (10) includes at least two wheels (16) and at least one motor (18), with each motor (18) being coupled with a corresponding wheel (16). A load sensing hitch between the tow vehicle (12) and the towed vehicle (10) provides an output signal representing a sensed load on the load sensing hitch. An electrical processing circuit is coupled with the load sensing hitch. The electrical processing circuit actuates at least one motor (18), dependent upon the output signal.
Abstract:
A method of controlling a vehicle involves determining if the vehicle is swaying (e.g., if a trailer being towed by the vehicle is exerting a sway force on the vehicle), and if the vehicle is swaying, reducing a torque of an engine of the vehicle and applying independent braking forces to each wheel of the vehicle. A vehicle for controlling vehicle sway includes an engine, a plurality of wheels, a braking system configured to apply independent braking forces to each wheel, and a controller configured to control the engine and the braking system. The controller is configured to determine if the vehicle is swaying (e.g., if a trailer being towed by the vehicle is exerting a sway force on the vehicle), and if the vehicle is swaying, reducing a torque of the engine and applying independent braking forces to each wheel.
Abstract:
A control system for a vehicle (10) for determining whether a trailer (12) is attached to the vehicle, the system being configured to receive an input of pitch data for the vehicle from pitch detection means and to determine from the pitch data whether a trailer is attached to the vehicle.
Abstract:
The invention relates to a controller for a hybrid electric vehicle (100) having an engine (121) and an electric machine (123), the controller (140) being configured upon start-up of the vehicle to control the electric machine (123) to provide torque to drive the vehicle (100) with the engine (121) off if a state of charge (SoC) of an energy storage device (150) is above an EV- start SoC threshold and to start the engine (121) if a SoC of the energy storage device (150) is below the EV- start SoC threshold, wherein the EV- start SoC threshold is determined to be one selected from amongst a value sufficient to allow the vehicle (100) to travel a prescribed distance before a SoC falls below a SoC minimum level at which the engine (121) is started and a value sufficient to allow the vehicle (121) to operate for a prescribed time period before the SoC falls below the SoC minimum level.
Abstract:
The disclosure relates to a system for controlling a hybrid vehicle having a primary power source such as an electric motor and a secondary power source such as an internal combustion engine, the electric motor and internal combustion engine each being connectable to a driveline of the vehicle. The system comprises a control unit operable to cause the internal combustion engine to be pre-emptively initiated and subsequently connected to the driveline. The control unit is configured and arranged to determine when the vehicle is in a first driving mode (wherein the internal combustion engine is not initiated and is disconnected from the driveline of the vehicle and wherein the electric motor and battery pack are delivering a torque to the driveline in response to a driver demanded torque). The control unit is further configured and arranged to determine that a steering angle of the vehicle and a situational status of the vehicle are indicative of a driving situation in which an expected driver demanded torque will not be met by the primary power source alone. In response thereto, the control unit is configured and arranged to automatically and pre-emptively cause the internal combustion engine to be initiated and connected to the driveline at a time before the actual driver demanded torque reaches or exceeds said expected driver demanded torque.

The invention further relates to a hybrid system, an electric motor, a method for producing a rotor-shaft arrangement, and the use of a rotor-shaft arrangement, a hybrid system, and/or an electric motor as and/or for a drive unit of an aircraft, watercraft, or land craft or as a generator in a power generation device.
Abstract:
The present invention relates to a method for the adaptation of the driving of a vehicle on a roadway in association with taking a curve. The method comprises the steps to determine (S1 ) the degree of curvature along the route of the vehicle and to adapt (S2) the speed of the vehicle based on the lateral acceleration of the vehicle. The method comprises further the steps to determine (S3) a maximum permitted lateral acceleration; and to adapt (S4) the maximum permitted lateral acceleration depending on properties of the vehicle and/or the surroundings that influence the safe driving of the vehicle when taking a curve. The step to adapt the maximum permitted lateral acceleration includes the step to determine a factor that corresponds to the degree to which the said properties of the vehicle and/or the surroundings influence safe driving of the vehicle when taking the curve, whereby the said factor includes the influence of properties of the surroundings in the form of the effective width of the traffic lane in which the vehicle is being driven. The present invention relates also to a system for the adaptation of the driving of a vehicle on a roadway in association with taking a curve. The present invention relates also to a motor vehicle. The present invention relates also to a computer program and a computer program product.
