Description

Flat accelerator pedal

Technical field

The utility model relates to technical field of automobile parts, and in particular to a kind of flat accelerator pedal.

Background technique

Accelerator pedal (hereinafter referred to as throttle) on the market is suspension type and floor type at present, and is arranged with brake at horizontal-type Column, in long-time driving conditions, in since to maintain a posture unsmooth generations of logical blood for a long time tired for leg and foot muscles, this When perception and hypotaxia of the driver to accelerator pedal and brake, easily generation distraction and maloperation, especially exist When the emergency that happens suddenly, not in time, this poses a great threat traffic safety for brake.Solution at present in this respect is main It is cruise system, but this has some limitations and risk, cruise system is practical to be can be only applied on highway；Speed The excessive system completion of giving of control will cause driver attention and not concentrate, on highway speed quickly, energy of dashing forward at emergency Power is completely inadequate.Once driver has adapted to the vehicle with cruise system, then go drive without this function vehicle when It waits, respond and driving ability to road conditions will weaken, and increase risk.And the numerous connection of cruise system electronic component Complexity, inherently there is risks out of control.

Utility model content

The technical problem to be solved by the utility model is to existing suspension type or floor type accelerator pedal, for a long time Driving conditions easily make leg generate fatigue, perception and hypotaxia of the driver to accelerator pedal and brake, the ability that should dash forward drop Low, there are biggish security risk, the utility model provides the flat accelerator pedal to solve the above problems.

The utility model is achieved through the following technical solutions:

Flat accelerator pedal, including bottom plate and daughter board, the bottom plate are set to bottom in automobile, and daughter board is opposite with bottom plate sliding Dynamic connection, the board direction of daughter board and the board direction of bottom plate are parallel；Daughter board slidably reciprocates relative to bottom plate, passes through sensor group The sliding position signal of part detection daughter board is simultaneously sent to Engine ECU, controls engine acceleration or deceleration with judgement.

Utility model works principle are as follows: daughter board and bottom plate are slidably connected, daughter board, bottom plate parallel to the ground can be set Set, sole can all be stepped down on daughter board in this way, exert a force sliding daughter board, especially in long-time driving conditions, accelerate and Speed-down action is relatively fewer, can loosen completely foot and leg, reduce feeling of fatigue, correspondingly improve underfooting control pedal Precision；The bottom plate of accelerator pedal is linked by sensor module with ECU (vehicle-mounted computer), when driver's right threading is on daughter board When front and back is smooth, the associated location signal of daughter board opposed bottom sliding is detected by sensor module, and transmits this to ECU Signal value (principle compared with suspension type throttle sensor the same), ECU pass through judgement control engine acceleration or deceleration.

It is placed on right crus of diaphragm car bottom plate further, since cancelling traditional throttle form using bottom plate plus the stacked system of daughter board It is in upper and lower relation with right crus of diaphragm, brake can be placed in the position of former suspension type throttle, be in oblique line context with throttle.Throttle and brake The handover operation of vehicle is in two-dimensional linear relationship, rather than traditional three-dimensional curve relationship is simple and efficient operation more, when needing to stop Che Shi, right crus of diaphragm forward upward touch on the brake.The utility model has been obviously improved the safety and comfort of driver.

Preferably, the sensor module includes resistance, brush and signal transmitting module；The resistance is set to the upper of bottom plate Plate face, the axis direction of resistance and the glide direction of daughter board are parallel；The lower face of daughter board is equipped with the electricity being adapted to the resistance Brush；The real-time tele-communication number of brush and resistance loop is sent to Engine ECU by the signal transmitting module.
