Embodiment 1
[0052] A parameter that characterizes the voltage value of the accelerator pedal depression displacement is defined as an adjustment parameter. The vehicle intelligent speed limit method adjusts the opening of the throttle valve by adjusting the adjustment parameters.
[0053] refer to figure 2 , a kind of intelligent speed limit method of vehicle, it comprises the following steps:
[0054] Measure the vehicle weight in real time, and form a real-time changing vehicle weight voltage value. Specifically, the pressure sensor 20 in the voltage sensor module 1 is installed at the bottom of the vehicle to measure the weight of the vehicle in real time.
[0055] Set the vehicle weight voltage value as a threshold. And judge whether the voltage value of the accelerator pedal depression displacement is less than the threshold value; in this embodiment, the comparison between the accelerator pedal depression displacement voltage value and the threshold value can be realized through...
Embodiment 2
[0062] This embodiment will illustrate the principle of the warning light 5 and the indicator light 4 in the first embodiment, and the principle of comparing the accelerator pedal displacement voltage value with the threshold value. Wherein, the accelerator pedal depression displacement voltage value is set to B.
[0063] refer to image 3 , the principle steps of the vehicle being in the alarm state are as follows:
[0064] S1, judging whether the switch button 10 is pressed, if it is pressed, the indicator light 4 is always off, and then proceed to step S2; if it is not pressed, the indicator light 4 is always on, and then proceed to step S6;
[0065] S2. Judging whether the voltage sensor module 1 outputs the vehicle weight voltage value C, if yes, proceed to step S3, and if not, proceed to step S6;
[0066] S3. The vehicle weight voltage value C is set as the threshold value, and it is judged whether the accelerator pedal depression displacement voltage value B is greate...
Embodiment 3
[0078] In Embodiment 1 and Embodiment 2, the pressure sensor 20 is used to measure the real-time vehicle weight of the vehicle. Wherein, the pressure sensor 20 is installed at the bottom of the vehicle. In this way, the vehicle will produce bumps during driving and transmit the shock sensation to the pressure sensor 20, causing the measurement accuracy of the pressure sensor 20 to be inaccurate. And when the vehicle is running, a large amount of dust will be adsorbed on the surface of the pressure sensor 20 . For this reason, this embodiment improves the pressure sensor 20 involved in Embodiment 1 and Embodiment 2.
[0079] refer to Figure 4 , one end of the pressure sensor 20 is connected to the bottom end of the vehicle through a shock absorbing device. A transparent protective cover 10 is mounted on the other end of the pressure sensor 20 .
[0080] refer to Figure 5 with Image 6 , The damping device includes a damping plate 30 , a damping spring 40 , a sliding pla...
