Abstract

The assembly has a pedal with a spring which returns the pedal towards a rest position for exerting, on the pedal, a permanent adjusting force against an action of a vehicle driver on a support shoe. The spring is conformed such that a value of the force varies based on the operating parameters of the vehicle and the engine, where the parameters of the vehicle and the engine are speed and fuel consumption, respectively.

Description

"Traction Control Accelerator Pedal Assembly"

  The invention proposes a motor vehicle accelerator pedal assembly that makes it possible to notify the driver of one or more information items.

  The invention more particularly proposes a motor vehicle accelerator pedal assembly which comprises: a support which is fixed to a vehicle body structure element; a pedal which is pivotally mounted relative to the carrier between an angular position; of rest and several angular positions for controlling the operation of the engine - a support pad on which the driver of the vehicle acts to pivot the pedal about its pivot axis to one of the angular control positions - means of return from the pedal to the rest position which exert permanently a biasing force on the pedal which opposes the action of the user on the support pad.

  Current motor vehicles generally comprise an electronic calculator which makes it possible to accurately determine the quantity of fuel to be injected into the combustion chamber of the engine, as a function of several operating parameters of the vehicle, such as, for example, the speed or the load. of the vehicle.

  The calculator can also be used to determine the resulting fuel consumption, either instantaneous consumption or average consumption over a defined period of time.

  According to a known embodiment, the fuel consumption thus determined by the electronic computer is notified to the driver by means of a display device arranged in the passenger compartment of the vehicle.

  However, to know the fuel consumption, the driver must look away from the road to watch the display device.

  The invention aims to provide means for informing the driver of the fuel consumption of the vehicle by non-visual means.

  In order to achieve this, the invention proposes a pedal assembly of the type described above, characterized in that the return means are shaped so that the value of the return force varies as a function of at least one operating parameter of the vehicle and / or engine.

  According to other characteristics of the invention: the pedal assembly comprises an electronic device for controlling the return means which is programmed so that the value of the return force varies as a function of the angular position of the pedal according to a first control law when the value of said parameter is less than a predefined threshold value, and in such a way that the value of the return force varies as a function of the angular position of the pedal according to a second control law when the value of said parameter is greater than or equal to the threshold value of said parameter; - The pedal assembly comprises a manually operated control member which is connected to the control device of the return means to allow the driver to change the value of the return force; the threshold value of said parameter is determined by the user when he acts on the control member; the first control law and / or the second control law is selected from a set of control laws when the user acts on the control member; the said operating parameter is the fuel consumption of the engine; the said operating parameter is the quantity of polluting elements produced by the engine.

  The accelerator pedal assembly is a component of the pedal of a motor vehicle, which also includes a brake pedal assembly, and possibly a clutch pedal assembly.

  The accelerator pedal assembly includes a mounting bracket that is attached to the body structure member, a pedal that is pivotally mounted relative to the support, and a shoe that is attached to one end of the pedal, by the intermediate the driver acts to pivot the pedal relative to the support, so as to control the operation of the engine.

  The pedal is pivotally mounted relative to the support about a horizontal axis between a rest position for which the driver does not act on the pad, and several angular actuation positions which each correspond to an action of the driver on the skate.

  The pedal assembly also includes biasing means of the pedal to its rest position, which exert permanently on the pedal a return effort.

  When the user acts on the pad to pivot the pedal to an actuating position, the return force produced by the biasing means opposes the action of the driver, thereby providing the driver with a feeling of resistance from the pedal to his action.

  According to a known embodiment, the return force is exerted by a spring, so that the value of the return force varies as a function of the angular position of the pedal about the horizontal pivot axis, relative to at his rest position. Thus, the more the actuating position of the pedal is away from the rest position, the higher the value of the return force is important.

  According to the invention, the biasing means of the pedal are shaped so that the value of the return force they exert on the pedal is also variable depending on at least one operating parameter of the vehicle or the vehicle. engine.

  The return means thus comprise an electric or electronic actuator, such as for example an electric motor, which is capable of being controlled electronically to produce the return force.

  For example, the operating parameter of the engine is its fuel consumption, or the production of pollutants, and the operating parameter of the vehicle is its speed.

  The vehicle then comprises an electronic device which makes it possible to determine the value of the operating parameter and an electronic device for controlling the actuator which is connected to the electronic device for determining the value of the operating parameter and which controls the actuator of the the actuator of the return means so as to exert the effort is is recall determined.

  According to a preferred embodiment of the invention, the electronic control device is programmed so that the value of the return force is determined according to the angular position of the pedal, from one or the other two different control laws, each control law being selected according to the value of the operating parameter.

  Thus, when the value of the operating parameter is lower than a threshold value of the parameter, the value of the return force is determined as a function of the angular position of the pedal according to a first control law, and when the value of the operating parameter is greater than the threshold value, the value of the return force is determined according to the angular position of the pedal according to a second control law.

  The control laws are defined in such a way that the value of the return force is greater when it is determined according to the second control law than when it is determined according to the first control law, for the same angular position of the pedal.

  Thus, the value of the return force felt by the driver is greater when the value of the operating parameter is greater than the threshold value, when the value of the operating parameter is less than the threshold value.

  According to an alternative embodiment of the invention, the electronic control device is programmed so that the value of the return force is determined as a function of the angular position of the pedal and as a function of the value of the operating parameter.

  According to another aspect of the invention, the vehicle comprises a control member which is connected to the electronic control device and that the driver can manually operate to change the value of the return force.

  This manually operated control member is arranged in the passenger compartment of the vehicle, at the driving position.

  The control member allows the driver to modify at will the programming of the electronic control device, increasing or decreasing the value of the return force depending on the traffic conditions, for example increase the value of the effort of recall when traffic conditions are fluid, or reduce the value of the return force when traffic conditions are difficult.

  The action of the driver on the control member consists, for example, in modifying the threshold value that makes it possible to select the first or the second control law, or to select the first or the second control law from among a set of laws. command stored in the electronic control device.

  According to a preferred embodiment of the control member, it consists of a potentiometer that the driver can operate freely.

  According to an alternative embodiment of the control member, it comprises a locking element, for example a key system, to prevent modification of the programming of the electronic control device by another person.
