Abstract
The invention discloses a kind of methods of electric vehicle driver acceleration request intents, pass through the parsing to accelerator pedal change rate, and the switching of driving cycles, reach the accelerator pedal amount of same mechanical opening, respond out different accelerator pedal aperture requests, it finally realizes the effect of different torque requests, the purpose of driver's acceleration intents is realized with this.
Description
Technical field
The invention belongs to electric car development development fields, the in particular to key components and parts based on C language platform
VCU develops test job, will be used for driver and accelerate intents.
Background technique
Mechanical intelligent has gradually come into our life, particularly evident to be just embodied in us and all using daily
On the vehicles-automobile, it is desirable to embody higher levels of mechanical intelligent on automobile, driver intention parsing shows outstanding
It is important.At this stage driver accelerate intents project plan comparison it is single, only simply according to accelerator pedal mechanical opening come
Differentiate that driver accelerates, the parsing intelligence degree of the intentions such as deceleration is lower.
Summary of the invention
The purpose of the present invention is to overcome the disadvantages of the prior art, provides a kind of accelerator pedal amount of same mechanical opening,
It different accelerator pedal aperture requests is responded out, finally realizes the effect of different torque requests, realize that driver accelerates with this
The method of the electric vehicle driver acceleration request intents of the purpose of intents.
A kind of method of electric vehicle driver acceleration request intents of the invention, comprising the following steps:
Step 1: judge driving mode, driving mode according to vehicle be divided into energy-saving mode, normal mode, motor pattern and
Snow field mode, different driving modes correspond to different accelerator coefficients；
Step 2: VCU, which reads accelerator pedal voltage change by rigid line first, obtains corresponding accelerator pedal mechanical opening,
Then mechanical pedal aperture change rate is obtained by the variation of accelerator pedal mechanical opening, is finally opened according to accelerator pedal machinery
Logic pedal opening is calculated in degree, mechanical pedal aperture change rate；
Wherein: mechanical pedal aperture change rate=(current accelerator pedal mechanical opening-last moment accelerator pedal is mechanical
Aperture)/N
N is the coefficient for calculating change rate in formula；
Snowfield, energy-saving mode logic pedal opening=accelerator pedal mechanical opening-mechanical pedal aperture change rate；
Motor pattern logic pedal opening=accelerator pedal mechanical opening+mechanical pedal aperture change rate；
Normal mode logic pedal opening=accelerator pedal mechanical opening；

Coefficient.
The beneficial effects of the present invention are: can be reached by the switching of parsing and driving mode to accelerator pedal change rate
The accelerator pedal amount of same mechanical opening responds out different accelerator pedal aperture requests, finally realizes different torque requests
Effect realizes the purpose of driver's acceleration intents with this.
Specific embodiment
The present invention is described in detail combined with specific embodiments below:
A kind of method of electric vehicle driver acceleration request intents of the invention, comprising the following steps:
Step 1: judging driving mode: existing vehicle driving model requires to be generally divided into energy-saving mode according to vehicle
(ECO), normal mode (NORMAL), motor pattern (SPORT) and snow field mode (SNOW), the corresponding difference of different driving modes add
Fast coefficient.Accelerator coefficient more large torque request answer speed is faster.The numerical value of accelerator coefficient can be carried out according to different vehicles
Calibration.
As one embodiment of the present invention: energy-saving mode and the corresponding accelerator coefficient of snow field mode are generally 0.5-1
Between, normal mode accelerator coefficient is generally 1, and the corresponding accelerator coefficient of motor pattern is generally between 1-2.
Step 2: VCU, which reads accelerator pedal voltage change by rigid line first, obtains corresponding accelerator pedal mechanical opening,
Then mechanical pedal aperture change rate is obtained by the variation of accelerator pedal mechanical opening, is finally opened according to accelerator pedal machinery
Logic pedal opening is calculated in degree, mechanical pedal aperture change rate；
Wherein: mechanical pedal aperture change rate=(current accelerator pedal mechanical opening-last moment accelerator pedal is mechanical
Aperture)/N
N is the coefficient for calculating change rate in formula, and N is bigger, and change rate is relatively smaller, and the smaller change rate of N is relatively bigger, N's
Specific value is demarcated according to vehicle demand.
Snowfield, energy-saving mode logic pedal opening=accelerator pedal mechanical opening-mechanical pedal aperture change rate；
Motor pattern logic pedal opening=accelerator pedal mechanical opening+mechanical pedal aperture change rate；
