Problems solved by technology

[0004] However, in the existing technology, when the load of the car changes and the stepping on the accelerator pedal is the same, the output power of the car engine is constant, but the final response of the car has changed. Although the throttle opening is uniquely corresponding to the output power of the car engine, this has existed for a long time problem, but for the driver, the driving experience is still affected to a certain extent

Embodiment 1

[0057] A weight-adaptive throttle control 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,

[0058] 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.

[0059] Include the following steps:

[0060] 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;

[0061] Step 2: Obtain the current real-time total vehicle weight;

[0062] Step 3: If the current real-time total vehicle weight is less than or equal to the calibrated weig...

Embodiment 2

[0097] 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

[0099] 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 throttle control method adaptive in weight and overcomes the defects of the prior art. According to the technical scheme, the throttle control method comprises the following steps: for an electric automobile or hybrid automobile, establishing a throttle opening comparison table and / or throttle opening comparison formula according to the total weight of the automobile, obtaining the total weight of the current vehicle, obtaining the current response correction value by inquiring the throttle opening comparison table or throttle opening comparison formula according to the total weight of the current automobile, and setting throttle response according to the actual opening and response correction value of a throttle. According to the throttle control method provided by the invention, an L-shaped air pipe is added, so that an error can be avoided from the hardware aspect by virtue of resistance of the air during slamming of a brake once the throttle and the brake are mistaken; meanwhile, reasonable electromagnetic valve opening is set, so that feel of feet can be kept consistent when the throttle is treaded, and consistency between control security and foot feel can be achieved.

Description

technical field [0001] The invention relates to a control method of an accelerator system, in particular to a weight adaptive accelerator control method. Background technique [0002] Application number: CN201510525267.7, published on 21.21.2015, discloses a newbie mode control method for preventing accidental stepping on the accelerator. It only needs to calibrate the ECU accelerator control part of the existing vehicle to realize error prevention The pedaling function is convenient to use and does not change the structure and operation method of the vehicle itself, which is beneficial to the popularization of existing vehicles. The present invention mainly comprises the steps: A, the user turns on the novice mode switch, starts the novice mode, and proceeds to the next step; B, the electronic control unit ECU monitors the opening of the electronic accelerator pedal and the rate of change, if the opening of the electronic accelerator pedal is within the time period If T ch...
