The specific embodiment
For the purpose, technical scheme and the advantage that make embodiment of the present utility model is clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is known complete description:
The judgement of accelerator instead of brake and correcting system mainly comprise: force feedback device, angle detection device and processing unit.
Be positioned at the force feedback device of Das Gaspedal below.This device is arranged on the below of an end of Das Gaspedal motion amplitude maximum.For multi-form Das Gaspedal, can be arranged on different positions, unsettled such as S. A., be positioned at the traditional pedal of the top of pedal, force feedback device is arranged on the pedal below.
Be positioned at Das Gaspedal S. A. position, detect the angle detection device of Das Gaspedal rotational angle, the hanging type Das Gaspedal for traditional is arranged on rotating shaft place of pedal rod.
Processing unit is electrically connected with described force feedback device and angle detection device.
During work, when chaufeur was stepped on the throttle pedal, the angle variation that angle detection device perception Das Gaspedal is stepped on changed, namely notice is given birth to angled variable quantity, and this variable quantity is sent to described processing unit, this processing unit starts inner time meter after receiving this signal; When the variable quantity of described angle reaches default first threshold, processing unit is according to time meter, calculate and whether surpass corresponding time threshold, determine whether maloperation, then be judged as maloperation if surpass, processing unit is trampled the dynamics of throttle action by acceleration calculation, dynamics information is sent to device for force feedback, apply the antagonistic force of identical dynamics for Das Gaspedal, reminding driver.
Consider in the situation of accelerator instead of brake, chaufeur belongs to the high-pressure state usually, and especially women's chaufeur can not guarantee the thinking of reason, the force feedback signal that Das Gaspedal may be transmitted continues to strengthen the dynamics of trampling throttle as the resistance that is brake.
Pretending is a better embodiment, also is provided with alarm module.Also be set with Second Threshold and interdependent time threshold in the processing unit: when the variable quantity of described accelerator pedal angle reaches Second Threshold in setting-up time, processing unit sends alarm message to described alarm module, alarm module can send continuous buzzer warning by the buzzer phone of self, also can set the voice audio alert.
When sending sound and light alarm, alarm module is connected with the oscillatory system that is arranged in automotive seat and the bearing circle, when sending warning, can control described warning device and produce vibration, make muscle generation contraction or the pause in short-term of chaufeur, contain that in time chaufeur continues the trend of mis-accelerator pressing.
Further, consider in the situation that extreme dangerous, a lot of new hand, especially female driver instincts moments of all can selecting to brake tramples on earth, namely tramples to extreme lower position throttle is instantaneous mistakenly.Therefore preferred, described processing unit also is connected with control unit of engine, simultaneously on the basis of first threshold and Second Threshold, set the 3rd threshold value and corresponding time threshold, when brake pedal angle variable quantity at the appointed time surpasses the 3rd threshold value, then processing unit judge current dislocation brake still continuing, assign out-of-work instruction to control unit of engine, avoid the generation of accident.
In actual use, described processing unit can be installed separately also and can embed in the car running computer.
On a large amount of experiment basis, the anglec of rotation for brake pedal is made stipulations, the angle of revolution at described Das Gaspedal initial point place is made as 0 °, and the degreeof turn variable quantity of first threshold is 30～50 °, namely is positioned at the scope that is first threshold apart from 0 ° of position 30-50 of pedal ° scope.
The difference of Second Threshold angle of revolution variable quantity and first threshold angle of revolution variable quantity between-3～5 °, the variable quantity of the 3rd threshold value and first threshold in 0～5 °.The rebound coefficient K of device for force feedback is 3.0kgcm/ degree～60.0kgcm/ degree.
Consider that the situation that the vehicle brake mistake is stepped on is mainly in the low speed driving process, especially particularly common in the situation of frequent starting or warehouse-in reversing.In the process of normally travelling, the pin of chaufeur all can be placed on brake or the Das Gaspedal basically, when the conversion pedal, is not easy to occur mistake and steps on.And when vehicle belongs to higher form speed, mean that also this moment on-road vehicle is also corresponding less, and even occuring, mistake steps on, the probability of chaufeur self-correcting is also larger.
Pretending is a better embodiment, described processing unit is set the critical speed Va of Vehicle Driving Cycle, when Vehicle Speed surpassed Va, described processing unit was controlled described force feedback device, angle detection device, alarm module and control unit of engine and is in dormant state.Guarantee that vehicle is in the state of normal form.
Embodiment 1, as shown in the figure: Das Gaspedal 1, be flexibly connected with bracing frame 4 by connecting rod 11 and S. A. 3, described angle detection device is integrated in the described S. A. 3, and rebound mechanism 5 can make brake pedal 1 keep in the center.
Described positioner 5 is arranged on the below of Das Gaspedal 1, can produce and the pedal effect resultant direction opposite effect power of stepping on the throttle.When aforementioned warning device sends alerting signal, produce described vibration.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
