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 invention aims in particular to propose a control device DC: on the one hand intended to be equipped to a vehicle V comprising a drive train comprising at least a first non-thermal prime mover MM1 and a second non-thermal prime mover MM2; and Another aspect is used to control coupling / disengagement of the first prime mover MM1.

[0029] In the following, it is considered, as a non-limiting example, that the vehicle V is a type of motor vehicle. This is for example a car. However, the invention is not limited to this type of vehicle. In fact, the invention relates to any type of vehicle comprising a drive train comprising a first prime mover and a second prime mover, the first prime mover being connectable to a first axle by a first coupling device, the second prime mover The prime mover may be coupled to the second axle through a shifter and be active during shifting by the shifter. Therefore, the present invention does not only relate to land vehicles, but also ...

Abstract

A device (DC) controls the coupling / uncoupling of a first prime mover (MM1), via first coupling means (MC1) to a first wheelset (T1) of a vehicle (V) also comprising a second wheelset (T2), and a second prime mover (MM2) able to be coupled to said second wheelset (T2) via transmission ratio-change means (BV) and which intervenes during changes in the transmission ratio of these means (BV). This device (DC) comprises control means (MCT) designed, in the event of a decision to change the transmission ratio, to at least temporarily prevent a change in the state of coupling of the first coupling means (MC1) during this change in transmission ratio when at least one predefined condition relating to a type selected from a type of change of coupling state and a type of change of chosen transmission ratio, is met.

Description

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