Description of the drawings
Fig. 1 is the structural schematic diagram that the electric vehicle deceleration of the present invention based under specific operation increases boat control system.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art with reference to specification text
Word can be implemented according to this.
Electric vehicle of the present invention based under specific operation, which slows down, to be increased in boat control system, involved specific work
Condition refers to NEDC operating modes, has specifically included four kinds under five kinds of deceleration-operations and the suburbs operating mode under urban conditions behaviour of slowing down
Make, has specific regulation for the speed of electric vehicle under these operating modes, therefore be easily identified in testing.
In order to improve the mileage travelled under above two operating mode, the electronic vapour of the present invention based under specific operation
It includes speed feedback unit and entire car controller that vehicle, which slows down and increases boat control system, and the entire car controller passes through the speed feedback
Unit obtains speed information, further includes deceleration identification module；Under the deceleration regime of electric vehicle, the deceleration identifies mould
Root tuber is calculated according to current vehicle speed information and target vehicle speed information needed for linear deceleration numerical value and correspondence needed for front deceleration
Target torque；The vehicle control unit controls electric motor of automobile exports power according to the target torque.
It is that the drive shaft of vehicle is directly imparted power to motor for electric vehicle, and entire car controller
It is the whole control unit of electric vehicle, is the core of whole-control system, is responsible for power output, power performance and energy pipe
Reason, by acquiring, receiving data and after calculation process, sends out control instruction to each control unit, controls the reality of vehicle
Border travels.For driver, by the operation to gear, accelerator pedal, brake pedal, driving intention is passed into vehicle
, and corresponding torque is calculated according to internal control algorithm by entire car controller, then moment of torsion control instruction is sent to motor
Controller drives vehicle to travel to control motor.Then, in the present invention, first by deceleration identification module according to current speed
Information and the target vehicle speed information to be reached of slowing down calculate the required linear deceleration numerical value of front deceleration and herein
Target torque under kind operating status needed for motor, then moment of torsion control instruction is sent out according to target torque by entire car controller, with
It is travelled by scheduled speed by electric machine controller to control motor-driven vehicle.
It should be noted that the data computing function involved by the deceleration identification module can also collect together in entire car controller
It is interior to be realized by newly-increased operation program, i.e., by entire car controller according to current vehicle speed information and the target carriage to be reached of slowing down
Fast information calculates linear deceleration numerical value, further, can also calculate the target under such operating status needed for motor and turn round
Square.Due to being run by linear ways of deceleration by controlling electric vehicle in the present invention, it is therefore not necessary to which human intervention can obtain
Expected slowing effect, moreover, because the control mode linearly slowed down is used, but also the operating status of electric vehicle is more
Ideal, the power consumption smaller of battery component, also increases the course continuation mileage under same electric quantity consumption, to improve electronic vapour
The test performance index of vehicle.Simultaneously as the electric machine assembly of electric vehicle has the characteristic that power generation is slowed down, therefore, above-mentioned
Electric energy production is had in linear moderating process, and the power generation torque in the moderating process that generates electricity can also meet under NEDC operating modes and slow down
Demand, then, if identify the deceleration intention of driver, and determination enter linear decelerating mode, so that it may control motor
Power generation make its export negative torque, this measure avoid driver trample brake pedal slow down and caused by energy loss.
Specifically, the electric vehicle of the present invention based under specific operation, which slows down, increases in boat control system, also wraps
Include accelerator pedal and brake pedal；The entire car controller according to the actuating signal of accelerator pedal, the actuating signal of brake pedal,
And current speed information determines the deceleration regime of electric vehicle.
Electric vehicle of the present invention based under specific operation, which slows down, to be increased in boat control system, further includes motor control
Device；The entire car controller controls the electric motor of automobile by the electric machine controller and exports power according to the target torque.
The present invention also provides a kind of electric vehicle decelerations based under specific operation to increase boat control method, i.e., in electric vehicle
Under deceleration regime, according to current vehicle speed information and target vehicle speed information calculate linear deceleration numerical value needed for front deceleration and
Corresponding required target torque；Again power is exported according to the target torque by vehicle control unit controls electric motor of automobile.Specifically,
The entire car controller can be controlled the electric motor of automobile by electric machine controller and export power according to the target torque.The present invention
The control method can slow down referring in particular to the electric vehicle above-mentioned based under specific operation increases boat control system to realize.
In the present invention, in order to determine that electric vehicle is currently entering deceleration regime, the action letter for acquiring accelerator pedal is needed
Number, the actuating signal of brake pedal and current speed information.For example, when collect accelerator pedal do not apply active force,
