Square, vehicle are not in undesirable movement, guarantee vehicle travel safety.
The steering of pure electric automobile is carried out according to the control system in the present embodiment, brakes preferential control, including following
Step:
Guarantee to turn to preferential: power-assisted steering electric machine controller 40 being associated with the tach signal of main motor 30, passes through power-assisted
Steering motor controller 40 reads the tach signal of main motor 30, and when the revolving speed of main motor 30 is greater than desired speed, power-assisted turns
Power-assisted steering motor 50, which is controlled, to electric machine controller 40 remains work.
Fig. 3 is the flow chart for guaranteeing to turn to preferential control method using embodiment in Fig. 2, as shown in Figure 3.Power-assisted is turned
It is associated with to electric machine controller 40 with the tach signal of main motor 30, i.e., power-assisted steering electric machine controller 40 reads master by CAN line
The tach signal of motor 30, when the revolving speed of main motor 30 is greater than desired speed, no matter whether entire car controller 10 turns to power-assisted
To 40 enable signal of electric machine controller, power-assisted steering motor 50 works at this time.Can guarantee vehicle when driving, even if driving a vehicle
In journey during the failure of entire car controller 10 or the connection wiring harness terminal withdraw of the needle cause high speed traveling caused by poor contact etc.
When without enable signal, power-assisted steering motor 50 can also work.Wherein desired speed value is by the matched speed ratio of practical vehicle and wheel half
Diameter determines.It can be calculated by following formula, N1=igV/0.377r, wherein r is radius of wheel (unit m), igFor reduction ratio, v is
Vehicle speed (unit km/h), generally 2-3km/h.
When the revolving speed of main motor 30 is not more than desired speed, power-assisted steering electric machine controller 40 controls power-assisted steering motor
50 stop working.
Guarantee that braking is preferential: main motor controller 20 being associated with the switching value of brake pedal 60, gas pedal 70, vehicle
When controller 10 gives main motor 20 demand torque of controller, if torque is driving torque, examined by main motor controller 20
The switching value of brake pedal 60 and the switching value of gas pedal 70 are surveyed, if main motor controller 20 detects opening for brake pedal 60
When pass amount is effectively or the switching value of gas pedal 70 is invalid, and the duration is greater than the first predetermined amount of time, main motor control
Device 20 does not execute the given torque of entire car controller 10, executes zero torque.
Fig. 4 is the flow chart for guaranteeing to brake preferential control method using embodiment in Fig. 2, as shown in Figure 4.By main motor

Broken strip part.This judges based under the driving condition of main motor 30, the main electricity in the case where the power generation of main motor 30 is energy regenerating condition
Machine controller 20 does not make a decision when executing vehicle torque.It need to increase by a new error code according to the above main motor controller 20,
Fault mechanism are as follows: when entire car controller 10 gives torque under the driving condition of main motor 30, this moment main motor controller 20
It detects the switching value of brake pedal 60 effectively or the switching value of gas pedal 70 is invalid and the duration is the first pre- timing
Between section when, main motor controller 20 does not execute the given torque of entire car controller 10, executes zero torque.It is second when the duration
When predetermined amount of time, and when the second predetermined amount of time is greater than the first predetermined amount of time, main motor controller 20 is to entire car controller
10 reporting faults.Wherein, the first predetermined amount of time and the determination of the value of the second predetermined amount of time are demarcated according to real vehicle, with system
Dynamic pedal 60 is related with the characteristic of gas pedal 70 and the period of CAN message.
Further, when entire car controller 10 gives main motor 20 demand torque of controller, if torque is non-driven torque,
Then main motor controller 20 executes entire car controller 10 and gives torque.
By using the control system and controlling party preferential for steering, the braking of pure electric automobile of the present invention
Power-assisted steering electric machine controller is associated with by method with the tach signal of main motor, as the Rule of judgment of power-assisted steering motor stopping,
Even if power-assisted steering electric machine controller does not receive enable signal, power-assisted steering motor can still work, and guarantee driving conditions transfer
To will not lack, and then guarantee traffic safety, main motor controller and the switching value of brake pedal, gas pedal are closed
Connection, as the Rule of judgment for executing entire car controller demand torque, when vehicle CAN network erroneous frame is higher or other reasons
When entire car controller being caused to give the driving instruction of mistake, the given torque of entire car controller, vehicle is not carried out in electric machine controller
Be not in undesirable movement, guarantee vehicle travel safety.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
