Definitions

  • the present invention relates to a system and a method for controlling the release of an automatic parking brake device on board a motor vehicle.
  • French Patent Application No. 2,828,450 discloses a system for controlling the release of an automatic parking brake device, on board a motor vehicle, in which, if conditions representative of a starting or a coasting maneuver are performed, a parking brake release command is issued a plurality of times, to brake actuators, requiring a multiple emission of a parking brake release command.
  • British patent applications GB 2 376 990 and GB 2 342 967 relate to the generation of a release control of a parking brake respectively according to the position of the clutch pedal and as a function of the torque measured at the wheels. . These documents also emit a plurality of times a command to release the parking brake.
  • a control system for the release of an automatic parking brake device, embarked on board a motor vehicle.
  • the system comprises transmission means for issuing several times a release command of the parking brake device, and interface means, arranged between said transmission means and said parking brake device, for receiving said transmission emissions. the release control and transmit a release command of said parking brake device.
  • the transmission means adapted for brake actuators requiring a multiple emission of a release control are easily adaptable, at reduced cost, to brake actuators for which the multiple sending of a release control is useless. .
  • said transmitting means are adapted to transmit a predetermined number of times said loosening command. Two successive transmissions are separated by a predetermined time interval.
  • the system includes manual, driver operable control means for controlling a release of the parking brake device.
  • said interface means are adapted to issue a release command of the parking brake device when:
  • said manual control means are not actuated or are defective
  • - Said transmission means emit a release command of the parking brake device, without issuing release command of the parking brake device within a previous time substantially equal to said predetermined time interval.
  • an assisted release of the brakes is possible if the brakes are effectively tightened, if the driver does not express any request by the manual control means or if the manual control means are defective, and if the conditions for starting on a hill or assisted coast maneuvering are carried out. When these conditions are not fulfilled, the loosening request is not transmitted to the brake actuators, and if the transmission means emit a disabling command of the automatic parking brake device, the interface means control the deactivation assistance of the parking brake device.
  • the system includes driver operable manual control means for controlling a release of the parking brake device.
  • Said interface means are adapted to emit a release command of the parking brake device when:
  • said manual control means are not actuated or are defective, and - Said transmission means emit a release command of the parking brake device, without issuing release command of the parking brake device within a previous time substantially equal to said predetermined time interval. It is thus possible to stop a clamping of the parking brake device and to perform a loosening immediately if a request for starting or coasting is made.
  • said interface means is adapted to disable the automatic parking brake device when said transmitting means issues a disengage command from the automatic parking brake device.
  • a method for controlling the loosening of an automatic parking brake device on board the motor vehicle in which a multiple emission of a release control of the device is modified. parking brake in an emission of a release command of the parking brake device for brake actuators unsuitable for said multiple emission of a release control.
  • the invention will be better understood on studying the following detailed description of some embodiments taken by way of non-limiting examples and illustrated by the appended drawing showing a control system of the release of a parking brake device.
  • automatic according to one aspect of the invention.
  • the figure illustrates an example of a control system of the release of an automatic parking brake device 1, on board a motor vehicle, to assist the driver during a hill start or a maneuver in side.
  • the device parking brake 1 is controlled according to different parameters by an electronic control unit 2.
  • the electronic control unit 2 is provided with an emission module 3 for issuing several times a release command of the parking brake device 1.
  • the electronic control unit 2 is provided with an emission module 3 for issuing several times a release command of the parking brake device 1.
  • the 2 also comprises an interface module 4 arranged between the transmission module 3 and the parking brake device 1.
  • the interface module 4 receives the successive emissions of a release command from the transmission module 3. 5. For example, successive releases of the loosening command are spaced apart by a predetermined time interval.
  • the interface module 4 transmits a release command to the parking brake device 1 via a connection 6.
  • the interface module 4 transmits a release command to the parking brake device 1 for the assembly. successive releases of the release command from the transmission module 3.
  • the automatic parking brake device 1 is, for example, controlled by the electronic control unit 2, so that, when the torque transmitted to the drive wheels of the vehicle compensates for the effects induced by the slope, the transmission module 3 of the electronic control unit 2 controls the release of the automatic parking brake device 1.
  • the electronic control unit 2 receives information representative of the slope ⁇ t ⁇ t of a slope sensor 8, via a connection 9.
  • the electronic control unit 2 also receives a plurality of other signals 10 provided by various sensors or estimators on board the vehicle. These signals are representative of the value of various parameters of operation of the vehicle, for example the position of the clutch pedal, the position of the accelerator pedal, the longitudinal speed of the vehicle, or the rotational speed of the engine.
  • the system further comprises a manual control module 1 1 connected to the electronic control unit 2 by a connection 12, and actuable by the driver, for controlling a tightening or loosening of the parking brake device 1.
  • the module manual control 1 1 may, for example, include a push button, a touch element, or any other element manually operable by the driver.
  • EPB status represents the state of the parking brake device 1
  • EPB switch represents the state of the driver - controlled manual control module 1 1
  • TOA demand represents the action of the transmission module 3
  • TOA demand ev represents the action of the interface module 4.
  • EPB status 2: clamping in progress
  • TOA demand a start aid strategy or hill climbing
  • the interface module 4 gives priority to the requests made voluntarily by the driver via the manual control module 1 1.
  • a request for loosening is sent to the parking brake 1 only when the brakes are really tight, which avoids trying to loosen brakes already loosened or loosening is already in progress.
  • this embodiment has the advantage of stopping a tightening of the brakes in progress and immediately making a release of the brakes when a request for assisted coast start or coasting or maneuvering assisted is generated.
  • the interface module 4 may take into account additional parameters such as the opening of a door, the presence of a driver, or the use of a safety belt, so as to further increase the safety of the occupants of the vehicle. vehicle.
