Definitions
- the invention relates to a unit of a so-called tachograph control device intended to be loaded onto a motor vehicle-in particular a vehicle for transporting goods or passengers-in order to enable the control of the activities of a driver of the vehicle.
- driver designates a person who can in turn exercise the activities of driver or co-driver (also called “conveyor") of the vehicle.
- the tachograph comprises, in addition to this unit, at least one vehicle motion sensor, to which the unit is intended to be connected.
- a tachograph has the particular function of recording, storing, producing, printing, and possibly exchanging and displaying, data, called driver data, relating to the activities of a driver of the vehicle, with a view to allow control of these activities by a controller.
- the tachographs currently used are of the tachograph type with disks, such as that described by US 4,782,691. These are analog and mechanical instruments for retranscribing conductive data on a paper disk by means of a stylus. Following a widespread trend in the automotive field, electronic tachographs have also been developed, including microprocessor circuits for the processing and storage of driver data. The introduction of electronics in tachographs has made it possible to envisage the implementation of new equipment within the tachograph unit and the realization by it of new functions.
- the tachograph unit be electrically powered continuously, regardless of the phase of operation of the vehicle in progress (contact established or not, engine of the stopped vehicle or engine running, vehicle to stopping or rolling vehicle ...), and this, not only in order to continuously process and store tachograph data, but also to allow a control of the activities of the driver at any time (and especially when the engine of the vehicle is stopped %), and especially to guarantee a total integrity of the data and a perfect coincidence between the reality of the facts and the recorded data (that these concern activities of the driver or the management of the equipments of the unit).
- it is not allowed to connect the tachograph unit only to a network, said network after contact, of the vehicle, which is electrically powered only after the established contact (for example by means of a key) by a user of the vehicle.
- a tachograph unit has a power supply circuit, intended to be permanently supplied by a permanent electrical source of the vehicle when the unit is on board a vehicle.
- this power supply circuit is connected to a network, said permanent network of the vehicle, which is permanently powered by the vehicle battery. Any device connected to the permanent network is connected at all times electrically to the battery, regardless of the operating phase of the vehicle.
- the tachograph unit is thus constantly supplied with electricity, at least as long as the electrical source (battery) is not exhausted.
- the inventors have determined that with the allocation of new equipment and functionalities to the tachograph unit, such an architecture - in which the unit is connected to the permanent network of the vehicle - no longer makes it possible to guarantee a sufficient level of security.
- the new equipment envisaged is, for some, highly energy-consuming.
- the multiplication of the features that must now offer the tachograph unit results in an increase in the amount of energy required for the operation of the unit and forces to resize its power supply circuit.
- the invention aims first of all to overcome these disadvantages, by providing an electronic tachograph unit capable of offering a level of services (equipment, functionalities, security, etc.) equivalent to, and even greater than, that defined by the new regulations. and international standards, without the risk of exhausting the permanent electrical source (battery) of the vehicle and without however having a larger footprint than known tachograph units.
- a level of services equipment, functionalities, security, etc.
- the invention also aims to provide a range of several tachograph units which, although intended for different types of vehicle and therefore subject to different electrical rules, have a similar design and a close architecture allowing a rationalization of the production and a lower cost.
- the aim of the invention is to propose at least one standard version of a tachograph unit (suitable in particular for most conventional goods transport vehicles) and at least one specific version -that is an isolated version of a tachograph unit (particularly suitable for transport vehicles of hazardous materials) whose differences are minor, and which can be produced by the same production line (with possible adaptations, minor and quick to implement).
- Another object of the invention is to provide a tachograph unit that offers improved performance including both in terms of functionality, safety and energy efficiency.
- An object of the invention is to provide a tachograph unit displaying low power consumption.
- the invention also aims to achieve all these objectives at lower cost, by proposing a low cost unit made from means, including electronic and electrical components, usual or possibly new but inexpensive.
- off contact mean any period during which the network after contact of the vehicle is not powered (contact not established), and the terms “after contact” designate any period during which the network after contact of the vehicle is powered.
- the invention relates to a tachograph unit intended to be loaded onto a motor vehicle and to be connected to at least one vehicle motion sensor, which unit comprises at least one microprocessor card) for the secure processing and storage of data, said tachograph data, comprising at least data, called conductive data, relating to activities of a driver of said vehicle.

- the main circuit and the power circuit being connected to each other by data transmission channels and / or signals.
- the invention therefore consists in assigning the tachograph data processing functions and the safety functions to a first circuit whose power supply is permanent, and in assigning certain power-consuming functions to a separate circuit which is normally powered only when the network after contact is activated.
- the inventors firstly found that the activation of the network after contact of the vehicle was generally controlled by a user of the vehicle for starting the engine of the vehicle, and that its deactivation was generally ordered immediately following the stopping said motor, so that the phases where the network after ignition is activated coincide substantially with those where the engine is running.
- the power operations which can be performed only after contact, are therefore normally when the engine is running and the vehicle's power source can be recharged.
- the inventors have also and above all demonstrated that the neutralization of the aforementioned power operations, off contact, does not affect the proper operation of the tachograph and ensures a high level of security. In particular, they demonstrated that, against all odds, the specifications of the new regulations were fulfilled despite this temporary neutralization.

- the main microprocessor is adapted to control the activation of the power supply on receipt of the signal after contact and for (except possibly waking up by an external device, as will be explained hereinafter) to deactivate the off-contact power supply (that is to say in the absence of reception of said signal after contact or reception of a signal representative of the deactivated state of the network after contact of the vehicle).
- the neutralization of the power operations is handled in software by the main microprocessor (as a function of a contact signal received by the latter).
- the main and power supplies are referenced to the same mass.
- the data and / or signal transmission channels between the two circuits preferably comprise high resistances. This standard version is particularly intended for conventional goods transport vehicles.
- the power supply is adapted to be connected (when the unit is on board) to the network after contact of the vehicle.
- the power supply is fed only when the network after contact is itself powered (activated).
- the signal after contact corresponds to the electric current received by the power supply when the network after contact is activated.
- Out of contact the power circuit is not powered (except possibly wakeup by a remote external device, as will be explained later), so that no power operation can be executed. In other words, the neutralization of power operations is managed purely "electrically".
