Problems solved by technology

However, there are still problems with this technical solution, mainly because there are large errors in the vehicle weight measurement method disclosed in the technical solution, which is prone to calculation errors, and the experience for passengers is relatively poor. Response correction simply gives the formula: T1 / W2=T2 / (W1+W2), which does not clearly involve the various situations of vehicle acceleration in different situations, and there are major technical problems, and it is difficult to achieve the described The technical effect of adapting the throttle output to the load, and its claim 1 only expresses the technical solution of "setting the throttle response according to the current load information", and the claim is obviously too large

Embodiment 1

[0030] A control method for a vehicle weight adaptive throttle system, suitable for electric vehicles or hybrid vehicles, establishing a throttle opening comparison table and / or a throttle opening comparison formula for the total weight of the vehicle to obtain the current total vehicle weight,

[0031] According to the current gross weight of the vehicle, query the throttle opening comparison table or the throttle opening comparison formula to obtain the current response correction value, and set the throttle response according to the actual throttle opening and the response correction value.

[0032] Include the following steps:

[0033] Step 1: Read the standard configuration parameters and the preset throttle opening to compare the vehicle's electrical output power to obtain the vehicle's calibrated weight value;

[0034] Step 2: Obtain the current real-time total vehicle weight;

[0035] Step 3: If the current real-time total vehicle weight is less than or equal to the c...

Embodiment 2

[0068] This embodiment is basically the same as Embodiment 1. The car in Embodiment 2 is provided with an L-shaped air pipe below the accelerator pedal, and a piston rod is arranged in the L-shaped air pipe. The upper end of the air pipe faces the accelerator pedal. The upper end of the piston rod is fixedly connected to the lower surface of the accelerator pedal, and the lower end of the L-shaped air pipe is provided with two vent holes, the sum of the diameters of the two vent holes is smaller than the diameter of the upper end of the air pipe, one of which is The vent hole is equipped with a safety redundant solenoid valve, and the safety redundant solenoid valve is connected to the automobile ECU. In step 1, the set pedaling limit speed has an adjustment range, and the pedaling limit speed is within the adjustment range and is equal to the set speed. The opening of the safety redundant solenoid valve is proportionally related, and the safety redundant solenoid valve is tran...

Embodiment 3

[0071] This embodiment is basically the same as Embodiment 1, except that the power distribution ratio of the two tires of the front wheels of the automobile is a standard configuration parameter, and the current real-time total weight and center of gravity of the automobile are calculated by the weight gauge carried by the wheels Position, extract the offset vector between the real-time center of gravity position and the preset center of gravity position, if the offset vector is maintained within a predetermined time, then obtain the current offset vector as the calculated value, with the horizontal axis of the car as the X axis and the vertical axis of the car as the Y axis The current offset vector is decomposed, and the tire power distribution ratio of the two front wheels is corrected proportionally according to the current X-axis offset vector decomposition value. 94% of the tire power distribution ratio of all wheels is the distribution fixed value, and 6% of the tire po...

Abstract

The invention relates to a control method of an accelerator system self-adaptive to automobile weight and solves the defects in the prior art. The technical scheme is as follows: the control method is applicable to electric automobiles or hybrid automobiles and is characterized by comprising the following steps: establishing an accelerator opening degree comparison table and / or an accelerator opening degree comparison formula for automobile total weight to obtain the current automobile total weight, looking up the accelerator opening degree comparison table and / or the accelerator opening degree comparison formula according to the current automobile total weight to obtain a current response correction value, and setting accelerator response according to the accelerator actual opening degree and the response correction value. Through the control method of the accelerator system self-adaptive to the automobile weight, a manner of the accelerator opening degree comparison table or comparison formula is used for corresponding to the current automobile total weight; the problem that the accelerator response is changed when the loads of the automobile are different is solved; the effects that the accelerator response of the automobile is set according to the current load information and the accelerator response can be unchanged or similar under different loads are achieved.

Description

technical field [0001] The invention relates to a control method of an accelerator system, in particular to a control method of an automobile weight adaptive accelerator system. Background technique [0002] Generally, the accelerator of a car controls the opening of the throttle to control the speed of the vehicle, but now electric vehicles or hybrid vehicles are emerging in the market as emerging vehicles, and the traditional method of controlling the throttle is no longer applicable. Electric vehicles or hybrid vehicles Although the car throttle is called a throttle, it mainly controls the output power of the motor to achieve the purpose of controlling the output. In general, it converts the output value by detecting the throttle opening, and then sends a drive command to make the motor output the corresponding power. [0003] Application number: CN201510148074.4, published on March 31, 2015, discloses a throttle response method and device, belonging to the automotive fie...
