Definitions
- the invention relates to the automatic control devices for stopping and / or starting a combustion engine of a motor vehicle also called "stop and start” starting devices according to the English terminology.
- the “Stop and Start” is to stop the engine when its operation is not essential and restart the engine as soon as possible when the driver needs it again.
- Stopping and restarting the engine represents an energy cost, corresponding to two or three seconds of fuel consumption at engine idling. All engine stops below this time therefore have a detrimental impact on the overall fuel consumption of the vehicle.
- the driver is not master of the stop of his engine by the stop and start function because the action he performs for slowing down the vehicle is synonymous with engine stop request when the speed becomes low, this is the case for example of pressing the brake pedal at a speed less than 5 Km / h.
- the invention aims to remedy these drawbacks.
- an automatic control device for starting and / or stopping a combustion engine of a motor vehicle, which device takes into account at least one action of a driver of the vehicle of in such a way as to initiate the stopping and / or starting of the engine according to the presence of this action of the driver, characterized in that the device also takes into account a result delivered by a vehicle detector preceding the vehicle equipped by the command so as to initiate the stopping and / or starting of the engine according to this result.
- the device takes into account a speed of the preceding vehicle to trigger a stop and / or start of the engine.
- the device takes into account a speed of the preceding vehicle and inhibits a stop of the engine in the case where the preceding vehicle is in the acceleration phase.
- the device takes into account a speed of the preceding vehicle and inhibits a stop of the engine in the case where the preceding vehicle has a speed greater than the vehicle equipped with said device.
- the device takes into account a speed of the preceding vehicle and triggers a start of the engine in the case where the preceding vehicle passes from a stationary situation to a rolling situation.
- the device triggers a start of the engine in the case where the preceding vehicle changes from a stationary situation to a rolling situation despite a detection of immobility of the vehicle equipped by the control device and despite detection of a action of the driver controlling the stopping of the engine of the vehicle.
- the device takes into account a speed of the previous vehicle and it initiates a start of the engine in the case where the preceding vehicle accelerates.
- the device takes into account a signal indicative of an action of the driver on a brake pedal of the vehicle equipped by the device as a condition for initiating a stopping of the engine.
- the device takes into account a signal indicative of an action of the driver on a brake pedal of the vehicle equipped with the device and takes into account a signal of disappearance of the action of the driver on the brake pedal as a condition to initiate a motor start.
- the invention also relates to a method for automatically controlling the starting and / or stopping of a combustion engine of a motor vehicle, comprising the steps of initiating a stop and / or starting of the engine taking into account at least one action of a driver of the vehicle so as to initiate the stopping and / or starting of the engine depending on the presence of this action of the driver, the method being characterized in that it comprises the step of also take into account a result delivered by a vehicle detector preceding the vehicle whose start and / or start of the engine is initiated so as to initiate the stopping and / or starting of the engine according to this result.
- FIG. 1 is a functional diagram corresponding to an automatic stop and start control device according to one embodiment of the invention
- FIG. 1 is a graph showing an evolution of different conditions affecting a stop and automatic start in this same embodiment.
- the stop and automatic start control device shown in Figure 1 comprises a control module 10 consisting of an onboard computer, and a series of condition detection devices to which the vehicle is subjected.
- the present device comprises a sensor 20 on a brake pedal of the vehicle, a vehicle speedometer 30 and a detector 40 of presence of a vehicle preceding the vehicle equipped with the present device.
- This presence detector 40 of a vehicle is here a driving assistance system.
- This driver assistance system 40 also called collision avoidance system typically aims to automatically control a distance between the vehicle equipped by this system and the vehicle in front of it.
- the present driving assistance system delivers a certain amount of information such as a measure of the distance separating such a vehicle from the vehicle which precedes it, the time which separates these two vehicles, and the speed of the vehicle. vehicle preceding the equipped vehicle.
- the information used primarily is the speed of the previous vehicle.
- this information here we will define the conditions relating to the speed of the preceding vehicle which must be respected to authorize the stopping of the engine as well as conditions relating to the speed of the preceding vehicle triggering an automatic restart of the engine by anticipation .
- the module 10 verifies the behavior of the front vehicle.
- the module 10 prohibits the engine stop. This type of situation is encountered on arrival at a traffic light passing "green" at an intersection without priority vehicles on the perpendicular roadway or in line. In these latter cases, the engine stopping time would have been too short, and the engine stop would have embarrassed the driver.
- the speed of the vehicle STT is represented by a track 100.
- the speed of the front vehicle is represented by a track 200.
- a speed threshold to authorize the stop is represented by a horizontal line 300.
- vertical line 400 corresponds to obtaining the driver stopping configuration.
- a vertical line 500 corresponds to obtaining the driver restart configuration.
- a vertical line 600 corresponds to a new obtaining of the driver stopping configuration.
- a vertical line 700 corresponds to a new obtaining of the driver restart configuration.
- two traces 800 and 900 represent signals which become active when the engine is stopped and inactive when the engine is in operation, these two lines 800 and 900 respectively corresponding to a control device according to the present embodiment and to a control device. control according to the prior art.
- the speed of the vehicle STT represented by the track 100 passes below the speed threshold 300.
- the engine stopping time between points 400 and 500 is long enough to be profitable.
- the speed 100 of the vehicle STT falls below the speed threshold 300.
- the speed 200 of the front vehicle is lower but is accelerating, so stopping is not authorised.
- the engine stopping time between 600 and 700 is too short to be profitable.
- the module 10 is also programmed to trigger a restart from results provided by the driver assistance device 40 in the case where the vehicle is preceded by another vehicle.
- the speed information of the front vehicle is used here to supplement the driver restart configurations.
- the module 10 anticipates restarting the engine of the vehicle STT before the driver releases the brake foot.
- the driver assistance device 40 emits a signal according to which the front vehicle starts rolling again or a signal formally constituting an engine restart command.
- the module 10 interprets the restart information and initiates the engine restart.
- the module 10 comprises a part of the driver assistance device, so that the interpretation of a restart of the front vehicle is carried out in the driver assistance device itself, a control of the driver assistance device. engine restart is then sent by the driver assistance device.
- the vehicle equipped with the present system has a speed of less than eight km / h and the driver has his foot on the brake pedal, and this conductive stop configuration has triggered engine shutdown especially because that the speed of the front vehicle was low enough.
- the driver assistance device 40 indicates to the module 10 that the front vehicle is accelerating, the module 10 initiates an engine restart in anticipation that the driver will need to accelerate too.
- the device In anticipation of the restart, the device allows the driver to no longer be bothered by a waiting time for the provision of engine torque, and the stop and start function becomes more transparent to the user.
- This embodiment has a significant technical interest directly visible by the driver of a vehicle STT. Indeed not only the unwanted motor stops are reduced in number, but we obtain a gain in consumption by the shorter stops are reduced and the driver's discomfort is reduced. By anticipating restarting the engine, we obtain a better transparency of the stop and start function for the driver, thanks to the fact that it eliminates a wait during departures following a motor shutdown.
