Embodiment Construction

[0046] FIG. 1 shows a power management system 2 for a motor vehicle, for example a hybrid vehicle. The management system is preferably an on-board system.

[0047] The management system 2 includes a power management unit such as a central ECU unit 4 .

[0048] The power management unit 4 is connected to the drivetrain of the car. The power transmission system includes a motor and an engine for providing front-wheel drive / rear-wheel drive, especially a heat engine 6, a motor 8 and a transmission chain.

[0049] The power management unit 4 is also connected to the power storage unit, in particular the battery 10, the charge level of which is monitored.

[0050] Preferably, said power management unit 4 is connected to a human-machine interface IHM 12 allowing it to communicate with the driver 14 of the vehicle.

[0051]The human-machine interface 12 thus allows the driver 14 to be informed of fuel consumption, battery 10 charge level, power costs, CO2 emissions, carbon footpri...

Abstract

The invention relates to a method for managing the power of a hybrid electric vehicle, which is selectively driven by an electric motor or a heat engine, the electric machine being powered by a power storage unit capable of being powered by the thermal Engine recharging, wherein the charge level of the power storage unit is monitored in order to select a mode in which the vehicle is driven by a heat engine or a mode in which it is driven by an electric motor, according to the method, the method comprising the steps of: a road map of the car associated with the trip; and based on said road map, determining (36) a threshold charge level (S2), referred to as the permission threshold, below which said car is driven by the heat engine Activated.

Description

technical field [0001] The invention relates to a power management method for a hybrid electric vehicle. The corresponding management system is also involved. [0002] In particular, the present invention relates to the technical field of hybrid electric vehicles. Background technique [0003] Typically, hybrid vehicles employ multiple separate power sources to drive the vehicle. These power sources typically include heat engines and electric machines associated with battery-type energy storage units. [0004] The presence of a second power source in a hybrid vehicle introduces an additional degree of freedom with regard to supplying the required power to the driver of the vehicle compared to conventional single thermally driven vehicles. [0005] Thus, there is a need to find a way to efficiently use the various sources available. In particular, unfavorable power management can lead to similar or higher power losses compared to the same conventional car, especially due ...
