Definitions
- TITLE METHOD FOR AUTOMATIC STARTING CONTROL OF A THERMAL ENGINE COMPRISING PRIORITIZATION OF THE ELECTRICAL SUPPLY OF THE SYSTEMS
- the field of the invention relates to a method for controlling the automatic start of a heat engine of a motor vehicle.
- the process relates more specifically to the phases of automatic stopping and restarting of the heat engine.
- the reliability of the on-board network power system is vital for the vehicle and increasingly critical due to the increasing number of robotic systems on board vehicles.
- robotic systems on board vehicles In addition to the numerous engine sensors, there are trajectory control systems, robotic braking systems, or even driving assistance functions which also require sensors and computers to perform the automated functions.
- DMT voltage maintenance device
- the prioritization function assigns other robotic systems a higher priority level than the starter. This is the case, for example, of the robotic parking brake system, the action of which takes priority in a restart sequence.
- the implementation of the protocol foresees that the brake system generates the inhibition request and transmits it to the heat engine control unit which consequently controls the starting prohibition. The generation of the inhibition request is dependent on the internal strategy of the brake system.
- Some brake system OEMs configure a start inhibition to be issued only when an actuator draws a large electrical current. This is the case for a brake calliper tightening/loosening operation involving hydraulic pressure regulation by a solenoid valve.
- other equipment manufacturers generate an inhibition for all the pressure regulations of the hydraulic circuit of the actuators, including the fine regulations lasting a few milliseconds. These fine regulations are likely to cause several consecutive interruptions of the restart and ultimately a motor shutdown for safety purposes and to count consecutive restart failures.
- FIG. 1 shows a situation of automatic stopping and restarting of the engine during which an inhibition request is generated twice successively at a time t0 and a time t3.
- the GR signal represents the engine speed.
- the lifting of the inhibition at time t0 corresponds to an operation of applying the parking brakes. Inhibition is lifted for about 300ms and ends at time t1. During this inhibition, a first rise in speed is observed, which is stopped. Then, at time t2, the engine speed is zero. At time t3, the motor initiates a restart and at the same time a second inhibition request is lifted by the parking brake system, due to fine regulation lasting a few milliseconds. This second inhibition causes the engine to stall at time t4 and finally an engine shutdown.
- One objective of the invention is to avoid motor cutouts resulting from untimely inhibition generated by a robotic system.
- Another objective of the invention is to propose improved motor control prioritization management capable of supervising different strategies for generating restart inhibition requests.
- the invention relates to a method for controlling the automatic start of a heat engine of a motor vehicle, the method comprising a power supply prioritization arbitration inhibiting the start of the heat engine according to an inhibition request generated during the piloting of a robotic system, the method comprising the detection of a first start-up inhibition request emitted by the robotic system.
- the method further comprises a second request to inhibit the starting of the heat engine triggered from the moment of detection.
- the second inhibition request is a delay of a predetermined duration.
- the predetermined duration is between 500 ms and 1500 ms.
- the first inhibition request is generated at the instant of triggering of a command to apply/release the robotic parking brake.
- the first inhibition request is generated at the instant of triggering of a command to open/close a motorized element of a door of the vehicle.
- a motor vehicle comprising a heat engine, a means of starting the heat engine, at least one robotized system, an electric power supply means and an arbitration means capable of inhibiting the starting of the heat engine according to an inhibition request generated during the piloting of the robotized system, in which the arbitration means is configured to implement the start control method according to any one of the preceding embodiments.
- the electrical supply means comprises a battery and the starting means and the robotic system are powered solely by the voltage delivered by the battery.

Thanks to the invention and the generation of the inhibition signal by the engine control unit, it ignores untimely changes in an inhibition signal generated by a robotic parking brake system. Successive start failures causing engine stalling are thus avoided.

- This request is made in the form of a timer or a counter that is triggered when an inhibition requested by a robotic system is detected. The timer is configured to reset once it has elapsed.
- the parking brake is placed at a higher priority level with respect to a request to restart the heat engine. It is also envisaged that other robotic systems may take priority over the starter, for example the robotic system of the vehicle doors.

- the request Tin has a duration at least strictly greater than the duration between the first rise, at time tO, and the second rise of request RQ1, at time t3. Throughout the duration of the second inhibition request Tin, the prioritization arbitration suspends motor starting.
- the second request Tin is a timer, or a counter, of a predetermined and configurable duration, in a value range of 500ms to 1500ms, for example 700ms. This duration is sufficient to cover the duration of the first rise until the appearance of a fine regulation of pressure, if necessary.

- Engine start is allowed.
- the motor start sequence is triggered.
- the starter is electrically powered and is placed in torque transmission with the heat engine shaft.
