Vehicle driving management system

The present invention relates to a system for managing the driving of a vehicle.

The present invention more particularly relates to a vehicle driving management system intended to be mounted on a thermal motor vehicle which comprises an on-board computer.

The invention applies in a preferred manner, but not limited to vehicles whose management of the pipe is not p.is_cha_cha ge by the on-board computer of the vehicle.

Indeed, since the 2000s, many thermal motor vehicles are produced by shipping an on-board computer that includes a set of hardware diagnostic means. This set of hardware diagnostic means is also called "Hardware Diagnostics" or "On Board Diagnostics" in English (usually abbreviated as OBD). The "Hardware Diagnosis" allows among other things access to relevant data (examples: temperature, pressure ...) relating to vehicle components.

Moreover, these vehicles do not always include systems to optimize a more ecological and / or more economical driving of the vehicle. For example, some vehicles do not incorporate a "Stop & Start" system or systems aimed at reducing the fuel consumption of the vehicle.

Thus, the applicant has sought to provide a system allowing among other things a more ecological and economical driving of a thermal motor vehicle and which is for example suitable for mounting on thermal vehicles comprising a set of hardware diagnostic means.

For this purpose, the invention relates to a system for managing the driving of a vehicle, said system comprising:
