Abstract:
A system includes a drive system (e.g., a vehicle drive system) and a controller. The drive system includes a motor and/or engine and a rotational component (e.g., gear or bearing) that is rotated during operation of the drive system. The controller is configured to receive operational information of the drive system and to determine an estimated lifespan of the rotational component based at least in part on torque, speed, and time information associated with the rotational component. The controller is further configured to control the drive system or another vehicle system based on the estimated lifespan. For example, for a bearing, the controller may be configured to track time of operation in different speed ranges and/or torque ranges, for determining a corrected speed and/or a corrected force, respectively, that is used for determining the estimated lifespan.
Abstract:
The invention relates to a suspension system for a sound damping device. The system comprises at least two fitting apertures 31 situated close to the upper side of the sound damping device, two arms 2 and at least two insulators 4. The insulators are intended to be fitted in said fitting apertures 31 and on said arms 2, each insulator comprising a rod 43 and the insulators being intended to be fastened to the sound damping device. The suspension system also comprises a fitting device 1 intended to be attached horizontally to the vehicles chassis and comprising two members 13, 14 intended to be situated opposite and parallel to one another, which fitting device is intended to accommodate the arms 2, the insulators 4 fastened to the arms and the sound damping device 5 fastened to the insulators 4. The arms 2 are intended to be parallel and be horizontally attached detachably close to the members 13, 14. The invention relates also to a vehicle provided with a suspension system.
Abstract:
The present invention provides a front engine/rear drive vehicle, such as a medium-sized bus, having a power transfer device and a sloped lower load floor (102). The power transfer means enables advantageous packaging of a drive shaft (18) for driving a rear-positioned drive. The sloped lower load floor (102) provides a continuously flat load floor without requiring a step over a differential (32) area. Further the sloped lower load floor (102) enables lower ground clearance at a front portion for implementation of a manageable wheelchair access ramp, as opposed to an expensive elevator system. Additionally, the sloped lower load floor (102) provides sufficient rear ground clearance for managing inclines and is kneelable enabling easier load/unload access to the rear of the vehicle.

Abstract:
The invention relates to a vehicle speed control system (10) that comprises a vehicle accelerator mechanism (20) manually moveable between a plurality of positions, a detection means (22) configured to detect the position of the vehicle accelerator mechanism (20) and to generate an output signal indicative of the position of the vehicle accelerator mechanism (20), a vehicle speed controller (80) configured to establish a speed of the vehicle as a function of said detected position of said manually controllable vehicle accelerator mechanism (20), and to use said output signal as an input speed control signal. Moreover, said vehicle speed controller (80) is further configured to be operably activated by a user (90) and to operate any one of a clutch unit (60), propulsion unit (30) and service brake (40), wherein, when said vehicle speed controller (80) is operably activated by the user to use said output signal as an input speed control signal, said vehicle speed controller (80) is further configured to be operated by the user to control the speed of the vehicle (1) by an operation of any one of the clutch unit, the propulsion unit and the service brake, allowing the user to manually control the speed of the vehicle as a function of the position of the vehicle accelerator mechanism (20). Moreover, the invention relates to a method of controlling speed of a vehicle by a vehicle speed control system.
Abstract:
The invention relates to a method for shifting in a vehicle (1) with a hybrid powertrain (2), comprising a combustion engine (3), an electric machine (4), a gearbox (6) with an input shaft (10) and a main shaft (14), wherein the combustion engine (3) and the electric machine (4) are connected to the input shaft (10) and a lay shaft (16), which via gear sets (50, 52 and 58, 60, 62) is connected to the input shaft (10) and the main shaft (14), so that they form a split gear unit (13) and a main gear unit (15). The method comprises the steps: a) to bring the main gear unit (15) into a substantially zero torque state, b) in the event the input shaft (10) and the lay shaft (16) must both be accelerated or decelerated: to initiate synchronisation of the speed of the lay shaft (16) with, on the one hand, the speed of the input shaft (10), and, on the other hand, the speed of the main shaft (14), at a joint first point in time (t1 ), c) to engage a gear in the split gear unit (13) when the speed of the lay shaft (16) has been synchronised with the speed of the input shaft (10) at a second point in time (t2), and d) to engage a gear in the main gear unit (15) when the speed of the lay shaft (16) has been synchronised with the speed of the main shaft (14) at a third point in time (t3). The invention also relates to a hybrid powertrain (2) and a vehicle (1), as well as a computer program (P) and a computer program product.
