Problems solved by technology

[0011] Thus, when a change in coupling state of the first coupling device needs to be performed while a gear shift is taking place, there may be insufficient power available in the energy storage device, which can lead to a reduction in the quality of performing the shift and / or coupling state change, the quality of which Descent manifested, for example, as jerks or intermittent shifting and / or coupling state changes

Embodiment Construction

[0028] The present invention is particularly aimed at proposing a control device DC: on the one hand for equipping a vehicle V comprising a drive train comprising at least a first non-thermal prime mover MM1 and a non-thermal second prime mover MM2; and On the other hand it is used to control the coupling / decoupling of the first prime mover MM1.

[0029] In the following, as a non-limiting example, the vehicle V is considered to be a motor vehicle type. This is for example a car. However, the invention is not limited to this type of vehicle. In fact, the present invention relates to any type of vehicle comprising a drive chain comprising a first prime mover and a second prime mover, the first prime mover being couplable to a first axle by means of a first coupling means, the second prime mover A prime mover may be coupled to the second axle through a shifter and act during a shift of the shifter. Therefore, the present invention not only relates to land vehicles, but also s...

Abstract

The invention relates to a device (DC) for controlling the coupling / disengagement of a first prime mover (MM1) via a first coupling device (MC1) to a first axle (T1) of a vehicle (V), the vehicle Also includes a second axle (T2) and a second prime mover (MM2), the second prime mover being adapted to be coupled to the second axle (T2) via a shifter (BV) and Active during gear changes. The device (DC) comprises control means (MCT) arranged to at least temporarily inhibit the coupling of the first coupling means (MC1) during the gear shift when at least one predetermined condition is fulfilled in the event of a determined gear shift A change of state, the predetermined condition pertaining to a type selected from a type of coupling state change and a determined shift type.

Description

technical field [0001] The present invention relates to a vehicle having a drive chain comprising at least a prime mover that is non-thermal and associated with a shifting device coupled to an axle, and another prime mover that is non-thermal and coupled to another axle, in conjunction with the shifting The prime mover associated with the gear device participates in the shift. Background technique [0002] Here, the term "prime mover" refers to a non-thermal engine, which is arranged to provide or recover torque for moving the vehicle, either alone or in addition to a possible heat engine. The prime mover may be, for example, an electric motor (or electric motor), a hydraulic machine, a pneumatic (or compressed air) machine, or a flywheel. [0003] As is known to those skilled in the art, some vehicles, optionally of the motor vehicle type, and optionally of hybrid power, include a drive train having a first prime mover and a second prime mover, the first prime mover passin...
