Problems solved by technology

In some cases, the vehicle may actually start to move, but the resistance may be so high that there is a risk of burning a clutch arranged between the vehicle's engine and gearbox, or that undesired wear on the clutch will be a result of the vehicle starting
In these cases, the clutch device may not be adequately controlled or designed to handle launch without excessive wear

Embodiment Construction

[0027] exist figure 1, a schematic diagram of a traction system 1 of a heavy-duty truck is shown. The traction system 1 comprises a first mechanical propulsion system 12 and a second hydraulic propulsion system 13 . The first mechanical propulsion system 12 comprises a pair of traction wheels (2a, 2b) on a rear driven axle 3 powered by an internal combustion engine (ICE) 4 . The rear driven wheel shaft 3 is connected to the ICE4 via the gearbox 5 . The gearbox 5 may be a manual or automatic step gearbox such as an automatic mechanical transmission (AMT), and the mechanical drive train may include a gearbox that is a dual clutch transmission (DCT) in order to shorten the time to change gears. The second hydraulic propulsion system 13 further comprises: a second pair of traction wheels 6a, 6b; a front wheel driven by a pair of hydraulic motors 8a, 8b connected to a hydraulic pump 7 and powered by The hydraulic pump 7 provides power. The traction system 1 also comprises a con...

Abstract

A method and vehicle traction system (1) comprising; - a first traction wheel (2a) forming part of a first propulsion system (12) comprising a mechanical drive train, - a second traction wheel (6a) forming part of a second propulsion system (13) comprising a hydraulic pump (7) for powering a hydraulic motor (8a), - one sensor (10a, 10b, 10c, 14) indicating a take-off condition, - a control unit (9) for controlling said second propulsion unit (13), wherein said control unit is programmed to; - automatically detecting a take-off condition by said sensor (10a, 10b, 10c, 14) and sending an input to the control unit (9) that a take-off condition is fulfilled, - automatically provide a traction force from said second propulsion system (13) in response to the indication that there is a take-off condition of the vehicle present and an indication that a traction is or will be provided by the first traction system, - automatically controlling said second propulsion unit (13) by the control unit (9) in dependence of the manually controlled torque from the first propulsion unit (12).

Description

technical field [0001] The present invention relates to a system and method for driveline control of a vehicle. The invention specifically relates to controlling vehicle and driveline features during vehicle launch. Background technique [0002] As is well known among drivers of motor vehicles is the fact that during launch maneuvers of such vehicles, situations arise in which, due to undesired launch conditions that prevent the vehicle from moving, for example, a heavily loaded vehicle attempts to When starting on an uphill, the torque from the driven wheels is insufficient and the wheels may skid or not travel. In some cases, the vehicle may actually start to move, but the resistance may be so high that there is a risk of burning a clutch arranged between the vehicle's engine and gearbox, or that undesired wear on the clutch will be a result of the vehicle starting . In these cases, the clutch arrangement may not be adequately controlled or designed to handle launch ope...
