Embodiment 1
[0041] Such as figure 1 , 2 Shown, a kind of vehicle acceleration pedal suppressing method comprises the steps:
[0042] Step S1: Use the acquisition device to detect whether there is an obstacle in the track interval in the direction of travel of the vehicle, and proceed to step S2;
[0043] Step S2: The controller obtains the obstacle information and the actual stroke information of the accelerator pedal, obtains the maximum stroke information of the accelerator pedal according to the obstacle information, and judges whether the actual stroke information of the accelerator pedal is within the safe stroke through the maximum stroke information, and proceeds to step S3, not Go to step S4;
[0044] Step S3: The controller converts the actual stroke of the accelerator pedal into a signal and sends it to the accelerator actuator, so that the car accelerates according to the actual stroke of the accelerator pedal;
[0045] Step S4: The controller converts the signal of the maxi...
Embodiment 2
[0075] The difference from the first embodiment above is that, in step S1 of the first embodiment, if no obstacle information is detected, the controller will make a wrong step judgment, and the wrong step judgment process is as follows:
[0076] Step S10: the controller obtains the actual stroke information of the accelerator pedal;
[0077] Step S11: According to the actual stroke information of the accelerator pedal, make a logical judgment of wrong stepping, if it belongs to wrong stepping, go to step S12, and if it does not belong to step S3;
[0078] Step 12: The controller sends the suppression signal to the acceleration actuator, and the car runs at idling speed. In the state of idling speed, the car does not accelerate, but moves forward slowly at its own speed, so as to realize acceleration suppression.
[0079] Specifically, the displacement sensor collects the actual stroke information c of the accelerator pedal in real time and transmits it to the controller. The ...
Embodiment 3
[0084]The difference with Embodiment 1 and Embodiment 2 is that: the insufficient situation in Embodiment 1 and 2 is solved, that is, when an obstacle is detected, there is also a sudden occurrence of misstepping, thereby realizing the "acceleration pedal "Acceleration suppression with a sharp increase in travel within a short period of time" and "acceleration suppression with obstacles in the trajectory area in the direction of travel" are triggered simultaneously and complement each other.
[0085] Such as Figure 4 As shown, the specific implementation process is: in step S2, when the safe travel distance is not satisfied, a wrong step judgment is made, if the wrong step is made, the controller outputs an acceleration suppression signal to the acceleration actuator, and the car runs at idle speed; if it is not a wrong step, then Execute step S4.
[0086] Specifically, when the acquisition device detects an obstacle but the driver does not see it at first (for example, a pe...
