Specific embodiment

Below in conjunction with attached drawing and preferred embodiment, the utility model is described in further detail, it should be clearly that, this place is retouched The preferred embodiment stated is only used for describing and explaining, and is not used to limit the utility model.

The utility model provides a kind of collection activation lock anti-misoperation accelerator pedal, it is identical with two pedals of brake throttle Operation mode carries out technology insulation: increasing a control vector, in the manipulation of gas pedal to distinguish the operation of brake pedal. When driver violates the operation mode that technical requirements use brake pedal, system can reduce the output power of motor in electric automobile extremely Shutdown or regenerative braking；Or internal combustion engine is reduced power and is braked to idling operation using engine drag, to avoid vapour Vehicle accelerates suddenly, effectively prevent accident.It as Figure 1-Figure 2, is that suspension type gas pedal lock panel longitudinally moves up mode, Including pedestal, stampeding section, the accelerator pedal position sensor 1 for detecting stampeding section position and accelerator pedal control unit. Stampeding section is connected on the base by pedal arm 2, and the stampeding section is divided into two layers up and down, and the lock panel 3 on upper layer covers lower layer Bottom-locking plate 6, and slightly a certain amount of extension, in case dust invades；Connected between lock panel 3 and bottom-locking plate 6 by sliding interconnecting piece It connects, the sliding interconnecting piece includes guide part, guiding auxiliary section and spring 7；The guide part is located on bottom-locking plate 6, and guiding is matched Conjunction portion is located in lock panel 3, and guide part and guiding auxiliary section match, and are oriented to auxiliary section and slide along guide part；The spring 7 One end be fixed on bottom-locking plate 6, the other end of spring 7 is fixed in lock panel 3, and the telescopic direction of spring 7 and guiding cooperate Portion is identical along guide part glide direction；If dry bearing 4 is arranged between the lock panel 3 and bottom-locking plate 6.Lock panel 3 in order to prevent Displacement triggering activation and gas pedal accelerate two movements to do things by following nature, and influence pedal and accidentally step on preventive effect, should be relative to oil Door pedal when being trampled lock panel 3 offset reprimand along the downward forced-slip trend of bottom-locking plate 6, the inverse upward low force touching group lock panel of gesture 3, so that lock panel 3 is made corresponding inverse gesture on bottom-locking plate 6 and move up, until bottom-locking plate 6 touches 3 lower end backstop of lock panel Side.

Read transducer 5, institute are dodged equipped with the displacement for detecting relative displacement between lock panel 3 and bottom-locking plate 6 in bottom-locking plate 6 Rheme is moved sudden strain of a muscle read transducer 5 and is electrically connected with accelerator pedal control unit.

Lock panel 3, by the pulling force effect of spring 7, is maintained at the bottom of running position under normal orientation, and bottom-locking plate 6 supports The firmly stop edge of 3 upper end of lock panel；The normal orientation be lock panel 3 under no external force in locating in gas pedal Home position.Leading right crus of diaphragm dials lock panel 3 against the upward low force touching of gesture, moves up it in 6 superinverse gesture of bottom-locking plate, until lock panel 3 Lower end stop edge touches the lower end of bottom-locking plate 6, i.e. lock panel 3 is moved to the top position, and triggering displacement is dodged read transducer 5, produced Raw signal activation accelerator pedal control unit, accelerator pedal control unit is according to control strategy by received gas pedal position It is sent to vehicle control unit of electric vehicle VCU or internal combustion engine control module ECM after setting the signal processing of sensor 1, it is real Freely accelerate under existing state of activation.Lock panel displacement is 3 lower end stop edge of lock panel and the lower end edge of bottom-locking plate 6 under normal orientation Distance, that is, lock panel 3 compare bottom-locking plate 6 generation specific extension amount.

On the other hand, when the un-activation of accelerator pedal control unit finds to further speed up, quick anxious accelerator pedal Strong acceleration signals is then judged as misoperation accelerator pedal, and accelerator pedal control unit is at once by accelerator pedal position sensor 1 Signal is converted to the shutdown of electric car and perhaps the idling operation signal of internal combustion engine and is sent to VCU or ECM, makes oil The assisted instruction of door pedal is invalid, and electric car is carried out regenerative braking according to VCU control strategy or remained shut off；Or internal combustion hair Motivation brakes using engine drag or keeps idling according to ECM control strategy.

Specifically, read transducer 5 is dodged in displacement is displaced triggering generation activation signal to lock panel 3, accelerator pedal control is single Member receives the signal and activates, and accelerates behavior without limitation in specific timeliness, can quickly deep accelerator pedal carry out strongly It is anxious accelerate, all acceleration functions of gas pedal activate completely, but gas pedal must one-way movement, it is continuous keep accelerating it is dynamic Make, this state is known as state of activation；Conversely, not triggering and activating, acceleration function is restricted then as unactivated state.

The specific timeliness of state of activation is in two stages: the first stage is activated to gas pedal from accelerator pedal control unit Start to accelerate motion, the time in this stage is more than that specific time threshold then activates failure, returns to unactivated state；Second-order Section accelerated motion since gas pedal stops to accelerated motion, this process must continue to accelerate and complete within a certain period of time, Once accelerated motion stops or withdraw gas pedal or the accelerator time is more than specific time threshold, then failure is activated, Return to unactivated state.

Lock panel 3 trigger simultaneously be maintained at the uninterrupted continuous trigger of trigger position, have and only once activate, activation timeliness from The time of initial trigger is counted, and then activates failure more than specific time threshold.Thus lock panel 3 need not be maintained at trigger bit It sets, lock panel 3 can be back to normal orientation after displacement triggering, wait mobile triggering next time, it can flash the touching of lock panel 3 Distribute into activation.It is displacement sensor that read transducer 5 is dodged in displacement described in the utility model, and of short duration flash only is needed in trigger process Lock panel 3 can make accelerator pedal control unit keep state of activation in certain timeliness.

The prevailing situation of unactivated state has: firstly, the initial position or stop position of electric automobile pedal；Or The idle position of internal combustion engine gas pedal is defaulted as unactivated state；Secondly, activation failure described in the utility model etc. It imitates in unactivated state.Under unactivated state, in addition to normally freely slowing down, gas pedal is merely able to maintain original position or oil Door tread depths are held essentially constant；Or within the scope of specific gas pedal change in depth or jogging speed to step on pedal slow Accelerate, more than the threshold value of setting, then accelerated step control unit is judged as that pedal is accidentally stepped on, and the accelerator pedal control unit is at once The signal of accelerator pedal position sensor 1 is converted to the shutdown of electric car or the idling operation signal of internal combustion engine, And be sent to vehicle control unit of electric vehicle VCU or internal combustion engine control module ECM, make the assisted instruction of gas pedal without Effect, electric car carry out regenerative braking or internal combustion engine according to VCU control strategy and utilize engine according to ECM control strategy It is counter to drag friction brakes.

At the same time, accelerator pedal control unit is locked in acceleration signals shutdown or the internal combustion engine of electric car Idling operation and record, this state be accidentally step on lock state.Under the state, gas pedal cannot be further used for lock panel 3 Displacement triggering activation and accelerate, gas pedal need be returned to the initial position or stop position or internal combustion of electric car The idle position of engine resets activation lock, could ring off signal locking；Accelerator pedal control unit is restored to receive processing oil The signal of read transducer 5 is dodged in the signal of door pedal position sensor 1 and displacement, and then again real according to the rule under different conditions Apply operation.

Accelerator pedal control unit is electrically connected with automobile instrument panel, determines that pedal is accidentally stepped on, into accidentally stepping on the same of lock state When, issue instrument panel lamp warning and audio alarm.After activation lock resets, all clear.

Gas pedal is in a certain depth or some position under unactivated state, can be changed into activation by being displaced triggering State implements fierce driving on the basis of original depth or position, but cannot touch the threshold value of activation failure.

The initial position or stop position of electric automobile pedal or the idle position of internal combustion engine gas pedal It usually can be set as maintaining home position operating condition under unactivated state, accelerating mode can be just only transitioned by activation, with Maximum probability pedal caused by this specific position is avoided to misapply event.

The downshift acceleration of automatic gear-box is limited under unactivated state.

For configuring the automobile of manual transmission, accelerator pedal control unit will also be with the clutch pedal switch electricity of vehicle Connection acquires clutch separation signal, with of short duration releasing Anti-mis-stepping function；

It similarly, is that suspension type gas pedal lock panel laterally moves to left mode, the lock panel 3 on upper layer covers shown in Fig. 3-Fig. 4 The bottom-locking plate 6 of lower layer simultaneously slightly a certain amount of is widened；Lock panel displacement is 3 right end stop edge of lock panel and lock under normal orientation The distance on 6 right end side of bottom plate compares the specific Widening of the generation of bottom-locking plate 6 relative to lock panel 3.Lock panel 3 is in normality By the pulling force effect of spring 7 under position, it is maintained at the right end of running position, bottom-locking plate 6 resists the backstop of 3 left end of lock panel Side.The displacement of lock panel 3 triggering activation and gas pedal accelerate two movements to do things by following nature in order to prevent, influence pedal and accidentally step on prevention Effect should correspond to lock panel 3 when gas pedal is trampled and mutually repel along the downward forced-slip trend of bottom-locking plate 6, low force Lock panel 3 is dialled in touching, and lock panel 3 is just made to make opposite transverse shifting on bottom-locking plate 6.Leading right crus of diaphragm laterally turn left low force touching dial lock Panel 3 moves to left it on bottom-locking plate 6, until the right end of 3 right end stop edge of lock panel touching bottom-locking plate 6, i.e. lock panel 3 are moved Left end position is moved, read transducer 5, the signal activation accelerator pedal control unit of generation are dodged in triggering displacement.

It similarly, is that organ type gas pedal lock panel longitudinally moves up mode shown in Fig. 5.

It similarly, is that organ type gas pedal lock panel laterally moves to left mode shown in Fig. 6.

The Anti-mis-stepping scheme of lock panel displacement vector control gas pedal accelerates the confirmation being intended to enhance driver, sentences Not precisely, manipulation is simple and direct；The anti-misoperation accelerator pedal scheme of multivariate vector control can also equally be introduced.Lock panel 3 and lock bottom There can be different matching relationships between plate 6, can also be fixed as one；Built-in near field touch sensing and accelerator pedal control are single Member electrical connection, and carry out motion capture according to specific foot posture action induction collaboration accelerator pedal control unit and sentence to identify Disconnected gas pedal accidentally steps on behavior.The near field touch sensing be one group of condenser type or ultrasonic type approach switch sensor, with Certain interval, sequence arrange, embedded to be arranged between lock panel 3 and bottom-locking plate 6, for incuding the sequentially-operating of foot； Lock panel 3 and bottom-locking plate 6, which are fixed as one, forms stampeding section.Similarly, it is also able to achieve this scheme using other type components, thus It is without being limited thereto.

The gas pedal controlled using 3 displacement vector of lock panel, is equipped with spring 7 and axis between lock panel 3 and bottom-locking plate 6 4 are held, 3 low force of lock panel that the pulling force of spring 7 is only sufficient under no external force is maintained at normal orientation, or flashes locking face in foot During plate, return lock panel is assisted, to enable the displacement light and fast of lock panel 3；Lock panel 3 and bottom-locking plate 6 are solid The gas pedal of fixed one is not necessarily to spring 7 and bearing 4, only arranges near field touch sensing.

Therefore, lock panel 3 and the mating surface of bottom-locking plate 6 can have different morpheme and geometrical relationship；Lock panel 3 and lock bottom The sensor, spring and bearing of different type quantity, different location and arrangement form can be installed between plate 6.

Gas pedal originally be electrically connected with accelerator pedal control unit, original electrical connection directly all shift and Accelerator pedal control unit electrical connection, by accelerator pedal control unit integrated treatment signal.

Accelerator pedal control unit is electrically connected with Anti-mis-stepping functional switch (ON/OFF), under the premise of determining safe driving Anti-mis-stepping function can be closed.

Accelerator pedal control unit can with self-contained independence, and with vehicle control unit of electric vehicle VCU or internal combustion engine Control module ECM electrical connection；Also it is desirably integrated into VCU or ECM.

The utility model is not provided with self-actuating brake system in the case where Context awareness technology accuracy of driving a vehicle is not guaranteed System, in case deep accelerator pedal causes autobrake system to judge by accident and increase vehicle rear-end collision accident under unactivated state, and fiber crops The vigilance of numbness driver manipulation.

The utility model is not limited to above embodiment, still can be to above-mentioned for related technical personnel Technical solution documented by each embodiment is modified, or part of technical characteristic is converted or improved.It is all this Within the essence spirit or principle of utility model, made any change, be all contained in the protection scope of the utility model it Interior, it is exactly the same for regarding similar.
