Problems solved by technology

[0004] However, in the above two existing technologies, there is a unique correspondence between the throttle opening and the output power of the car engine. Therefore, once 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 This is a problem that has existed for a long time, but for the driver, the driving experience is still affected to a certain extent

Embodiment 1

[0031] A throttle weight self-adaptive method for electric or hybrid vehicles, 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,

[0032] 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.

[0033] Include the following steps:

[0034] 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;

[0035] Step 2: Obtain the current real-time total vehicle weight;

[0036] Step 3: If the current real-time total vehicle weight is less than or...

Embodiment 2

[0071] 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

[0073] 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 an accelerator weight self-adaptation method of an electric or hybrid automobile. Shortcomings in the prior art are overcome. According to the technical scheme, for adapting to the electric or hybrid automobile, an accelerator opening degree comparison table and / or an accelerator opening degree comparison formula are / is built for the automobile total weight, the current automobile total weight is obtained, according to the current automobile total weight, the accelerator opening degree comparison table or the accelerator opening degree comparison formula is inquired, a current response correction value is obtained, and according to the accelerator actual opening degree and the response correction value, an accelerator response is set. An accelerator pedal obtains the response correction value by adopting the accelerator opening degree comparison table within the set micro range and within the set large opening degree limit range, and when the accelerator opening degree is within the set medium range, the comparison formula is adopted to obtain the response correction value.

Description

technical field [0001] The invention relates to a control method of an accelerator system, in particular to an adaptive method for the throttle weight of an electric or hybrid vehicle. Background technique [0002] On May 13, 2009, an automobile accelerator pedal safety device (200810204700.7-application number) was disclosed, including the accelerator pedal, an inner sleeve, and an accelerator connecting rod. The accelerator pedal is provided with an oval inner sleeve, and the accelerator connecting rod The cross-section is elliptical, and the inner sleeve covers the accelerator connecting rod, and the inner sleeve and the accelerator connecting rod are provided with a circuit switch that can cut off the power supply of the vehicle when the accelerator pedal rotates down. The invention is used for the safe use of the accelerator pedal of the automobile. The accelerator pedal can ensure the normal running of the car. When the accelerator pedal is mistakenly used as the brake...
