Embodiment 1

[0040] An automobile throttle adaptive method, 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 weight of the vehicle,

[0041] 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.

[0042] Include the following steps:

[0043] 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;

[0044] Step 2: Obtain the current real-time total vehicle weight;

[0045] Step 3: If the current real-time total vehicle weight is less than or equal to the calibrated weight ...

Embodiment 2

[0080] This embodiment is basically the same as Embodiment 1, and the difference in Embodiment 2 is 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 ratio is calculated by the weight meter carried by the wheel. The total weight of the car and the position of the center of gravity, 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, take the horizontal axis of the car as the X-axis car The vertical axis is the Y-axis decomposing the current offset vector, 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 fi...

Embodiment 3

[0082] It is basically the same as Embodiment 1, the difference is that in step five, if the accelerator opening is within the set range, the current accelerator pedaling speed is obtained, and if the accelerator pedaling speed is greater than the set value, it is obtained by comparing the formula The response correction value, if the accelerator pedaling speed is less than or equal to the set value, the response correction value is obtained by comparing the accelerator opening comparison table.

Abstract

The invention relates to a self-adapting method for a car accelerator in order to overcome defects in the prior art. The technical scheme is as follows: the self-adapting method is suitable for electric vehicles or hybrid electric vehicles and comprises the steps of establishing an accelerator opening contrast table and / or an accelerator opening contrast formula for the total weight of a car; obtaining a response correction value in a way of the accelerator opening contrast table when an accelerator opening value is smaller than or equal to a micromotion range value or is larger than or equal to a limit range value; obtaining the response correction value in a way of the contrast formula when the accelerator opening value is larger than the micromotion range value and is smaller than the limit range value; calculating standard electric output power according to the real-time accelerator opening of a car; and outputting the power of each tire of the car by taking the product of the standard electric output power and the response correction value as the final car electric output power according to a power distribution ratio.

Description

technical field [0001] The invention relates to a method for controlling an accelerator system, in particular to an adaptive method for an automobile accelerator. Background technique [0002] Application number: CN200920172620.8, published on February 24, 2010, discloses an electronic throttle controller for automobiles, including a housing, a circuit board, and a CPU signal controller. The CPU signal controller is arranged on the In the casing, the electronic controller of the throttle is used to control the rising or decreasing speed of the voltage. The circuit board is arranged in the casing, and one end is provided with a power line and a throttle control line. The power line is connected to the storage battery, and the throttle control line is connected to the control The throttle controller of the automobile ECU unit is connected, and the other end is provided with a throttle plus button and a throttle minus button. connect. By pressing the throttle plus button and ...
