Definitions
- the invention relates to the supply of onboard electrical equipment on board a motor vehicle.
- the invention relates to a system and a method for managing the operation of a motor - alternator assembly for powering such equipment with electrical energy.
- the alternator-motor unit is then driven only from the consumption required by the equipment.
- the first solution consists of keeping the engine speed constant and carrying out load shedding for part of the equipment, as long as the engine and the alternator are not able to supply the requested power. But a number of electrical devices can not be unloaded. This is particularly the case of the power steering whose operation must be maintained permanently. In addition, this type of technique can cause stalls or malfunctions in electrical equipment, especially when the engine is idling.
- Another solution is to increase the speed of the engine so as to increase the amount of available electrical energy.
- the engine speed, or its torque is controlled from the current consumed.
- the object of the invention is to overcome the drawbacks associated with the solutions of the state of the art and to make it possible to supply onboard electrical equipment on board a motor vehicle without loss of function and with increased responsiveness.
- the invention therefore relates, in a first aspect, to a system for managing the operation of a motor-alternator assembly for the supply of on-board electrical equipment on board a motor vehicle.
- This system comprises means for processing control parameters of the equipment and means for controlling the motor-alternator assembly according to the control parameters.
- the engine and the alternator are driven from the parameters or control values of the equipment.
- the system comprises means for estimating the consumption of equipment from said parameters and means for controlling the motor-alternator assembly so as to deliver a quantity of electrical energy corresponding to said consumption.
- the system may further comprise means for offloading at least part of the electrical equipment if the consumption of the equipment can not be satisfied.
- the load shedding means comprise a filter adapted to filter control signals of the equipment, in particular by delaying the control signals or developing ramp control signals.
- the invention also relates, in a second aspect, to a method of managing the operation of a motor-alternator assembly for the supply of electrical equipment on board a motor vehicle.
- the consumption of the equipment is estimated from said parameters and the motor / alternator assembly is controlled so as to deliver a quantity of electrical energy corresponding to said consumption.
- This shedding can be implemented by delaying the supply of at least part of the equipment. It can still be implemented by gradually supplying said equipment.
- control parameters comprise at least one parameter chosen from an angle of the vehicle steering wheel, the position of control switches for the operation of electrical equipment, and variables derived from control laws of the vehicle. vehicle.
- the system shown in the accompanying drawing is intended to manage the supply of a set of electrical equipment, such as E l, E 2 and E 3, by controlling the alternator A and the heat engine M so as to deliver them with energy electric that corresponds, at any time, to their consumption.
- electrical equipment means any type of device on board a motor vehicle, intended to be powered from the alternator.
- the number of powered equipment, here three in number, is in no way limiting.
- the equipment to be supplied with power is electrical power steering. (DAE) of the vehicle or a GEP electric pump unit (equipment E l), or a water pump associated with a GMV fan unit (equipment E2), or an air conditioning compressor (equipment E3).
- DAE electrical power steering.
- equipment E l a GEP electric pump unit
- equipment E2 a water pump associated with a GMV fan unit
- equipment E3 an air conditioning compressor
- the control of the alternator A and the motor M as a function of the consumption of the equipment is particularly advantageous when the engine is operating at an idle speed by making it possible to deliver to the equipment E 1, E 2 and E 3 an electrical energy which corresponds to their consumption while avoiding any risk of stalling for the motor M.
- the electrical equipment El, E2 and E3 draw a current from the alternator, which is rotated by the heat engine M.
- the equipment E 1, E 2 and E 3 each perform a basic function for the vehicle. They are controlled from control signals from appropriate sensors, from control commands developed by action on a control member manually operable by the driver, or by signals from control laws, such as laws. control system for controlling the operation of the engine according to its operating phases.
- the power steering DAE or the electric pump group GEP can be controlled from a sensor C l of the steering wheel angle and / or the steering wheel torque.
- the water pump and the GMV fan unit are controlled by a water temperature sensor C2.
- the air conditioning compressor E3 is controlled by a control button B placed for example on the dashboard.
- the system is constituted by a calculation module, for example incorporated in the central computer C of the vehicle in which the control laws of the engine and the alternator are incorporated in order to control them in function. phases of operation of the vehicle.
- control consists in modifying the operating speed of the engine so as to increase the delivered torque c to the alternator when it is determined that the consumption will be increased.
- the system uses the control signals for equipment E 1, E 2 and E 3 in order to estimate their overall consumption and to drive the alternator and the motor accordingly.
- the computer C is able to determine the consumption of the power steering of the electric pump unit (equipment E l), the water pump and the fan assembly (equipment E2) and the air conditioning compressor (equipment E3).
- the computer C incorporates a model m in which are stored, for example, current consumption values for different values of the signals from the sensors C 1, C 2 and for different positions of the control button B.
- the computer C continuously monitors the value of the control parameters of the equipment El, E2 and E3 to deduce directly, even before the consumption of these equipment has been established, the amount of current to be delivered by the alternator and thereby drives the engine and the alternator, in particular by adjusting the engine rotation speed and torque so that the alternator receives a torque c such that it is able to deliver the required current.
- the device then incorporates filtering means F filtering the signals carrying the control parameters of these devices in order to delay their operation.
- Such a delay can be implemented by causing a temporal shift of the control signals or by developing ramp control signals so as to progressively supply power.
- the engine and the alternator of the vehicle are controlled by control parameters of electrical equipment on board the vehicle, it is possible to establish the level of current available for these vehicles. equipment from information available upstream, that is to say of signals developed before implementation of these equipment, and not from the current consumed, which makes it possible to adapt in real time the current delivered by the alternator.
