Step 2: determining the running condition of the vehicle according to the acquired environment data information
In this embodiment, the vehicle driving condition is divided into a low-speed congestion condition, a medium-speed condition, a high-speed condition, an ascending slope, a descending slope and other various conditions.
Specifically, give the commodity circulation car a commute operating mode from making a round trip between two cities, wherein contain one end highway operating mode, speed settlement scope:
and (3) low-speed working condition: 0-50 km/h; medium speed: 50-90 km/h; high speed: 90-130 km/h.
Using data collected by a vehicle speed sensor, a gradient sensor and the like, judging that when the vehicle speed is in a low-speed section, the distance between a target vehicle and a front vehicle and a rear vehicle is less than a first set value k, the speed of the target vehicle is less than 20km/h or the number of times of 0km/h is more than a second set value m, determining that the vehicle is in a congestion working condition at the moment, and the vehicle cannot directly respond to an output signal of an accelerator pedal sensor to control the vehicle speed, wherein the vehicle speed needs to be controlled according to the following strategies of load and speed limit, if the target vehicle speed is always 50-90km/h and the vehicle speed is occasionally 0, the vehicle is considered to be in a medium-speed working condition, and if the target vehicle speed is uphill, the vehicle speed needs to be judged to be in an uphill or a downhill according to the gradient sensor, if the target vehicle speed is downhill, the vehicle speed needs to be controlled according to the load and the following speed limit strategy, and if the vehicle speed is always in a high-speed working condition, the vehicle speed need not be controlled based on load and the speed limit control strategy described below as long as it is not on a downhill slope for fuel economy.
The low-speed congestion condition is shown in fig. 2, and the medium-speed congestion condition is shown in fig. 3, wherein the ordinate represents the vehicle speed, the abscissa represents the vehicle speed congestion factor, and congestion is serious if the abscissa is greater than 100.
The environmental data information corresponding to each working condition is obtained in advance, and specifically:
the method comprises the steps that commuting historical working condition data in a vehicle form, such as vehicle speed, acceleration, gradient and congestion degree of running working conditions, are collected through a GPS positioning module, a gradient sensor, a vehicle speed sensor, an acceleration sensor and the like, the collected historical environment data are processed and analyzed through a K-means clustering algorithm, and various working conditions such as low-speed congestion working conditions, medium-speed working conditions, high-speed working conditions, uphill slopes, downhill slopes and the like are classified.

At the moment, the voltage threshold of the pedal voltage is limited by the voltage signal collected by the pressure sensor, so that even if a driver steps on the accelerator suddenly due to driving technology, fatigue driving or malicious reporting, the opening of the throttle valve cannot be changed due to the accelerator, the throttle valve is limited by the voltage sensor, namely the load of the vehicle, and potential safety hazards are avoided.
When the vehicle running working condition is judged to be a medium-high speed working condition and a non-downhill working condition, or the vehicle running working condition is an uphill working condition:
in order to ensure the driving dynamic property of the vehicle, the pedal voltage corresponding to the voltage signal acquired by the accelerator pedal sensor is directly used as the final voltage threshold value for outputting, and a limiting strategy based on a pressure sensor is not required to be added.
At the moment, the maximum vehicle speed threshold is determined according to the actual driving requirement and is not limited by the load, so that economic benefit loss caused by the fact that the output torque is limited by the load all the time is avoided.
By adopting the control strategy, the highest speed threshold can be reduced under the condition of ensuring the load of the vehicle on the traffic jam road section and the downhill working condition; in a smooth traffic area or a high-speed working condition, the maximum speed threshold is determined according to actual driving requirements, so that the driving safety of the vehicle is effectively improved, and the economic benefit loss caused by the loading speed limit of a single vehicle is avoided.
And 4, step 4: and controlling the opening of the throttle valve according to the determined pedal voltage, and further realizing the dynamic regulation of the highest threshold value of the vehicle speed according to the vehicle weight and different driving environments.
Specifically, a pressure signal of the pedal voltage is sent to the ECU, the ECU integrates information such as the current vehicle speed, the vehicle distance, the opening degree of a throttle valve, the rotating speed of an engine and the like, the optimal opening degree of the throttle valve is calculated, the ECU controls the output torque of a servo motor of the throttle valve, the opening degree of the electronic throttle valve is continuously adjusted, a throttle valve position sensor feeds back a throttle valve position signal to the ECU to form closed control, and finally the electronic throttle valve is stabilized to the optimal opening degree.
