Abstract
The present invention is a kind of electric vehicle brake method, and electromagnetic braking is increased in conventional vehicular brake mode to ensure vehicle and personnel safety in vehicle travel process.Electric vehicle electromagnetic braking is when driving by detecting vehicle foot brake and hand braking working condition in real time, by detecting braking system performance parameter, when parameter is judged as that braking system completely or partially fails beyond entire car controller in controlled range, entire car controller is just according to running velocity and the direction of motion at this time, brake force is calculated by specified criteria, and brake force is sent to electric machine controller and is simultaneously emitted by braking mode, the output that motor is controlled by electric machine controller generates the electromagnetic system power opposite with the direction of motion, reversed electromagnetic braking power acts between motor and transmission device, transmission device is embraced, to realize that electric vehicle vehicle is braked.
Description
Technical field
The present invention is suitable for pure electric automobile, hybrid vehicle, including but not limited to above-mentioned field.
Background technology
Existing automobile foot brake and hand braking system rely primarily on contact friction catch, and basic functional principle is to utilize and vehicle
Phase mutual friction between the connected non-rotating component of body (or vehicle frame) and the rotating element being connected with wheel (or transmission shaft) hinders
The only trend of rotation or the rotation of wheel.When driving, once there is foot brake or hand braking failure, vehicle can not be timely
Stop traveling, easily lead to traffic accident, causes casualties and property loss.
Invention content
Electromagnetic braking of the present invention is different from traditional braking method, is a kind of Novel brake method, in traditional pin
In the case of braking or hand braking complete or partial failure, can by detect foot brake and hand braking system analog signal,
The state of on-off model and according to condition adjudgement braking system whether failure, calculate system by specified criteria if failure judgement
Power, and brake force is sent to electric machine controller and is simultaneously emitted by braking mode, the output that motor is controlled by electric machine controller is produced
The raw electromagnetic system power opposite with the direction of motion, reversed electromagnetic braking power act between motor and transmission device, and transmission is filled
It sets and embraces, to achieve the effect that make vehicle to stop.
Specific implementation mode
This braking method is mainly generated by entire car controller, electric machine controller, driving motor and corresponding software programming
Electromagnetic system power is realized.
When driving, entire car controller detects port by being connect with corresponding test point, can detect foot brake in real time
And the parameters such as hand braking pressure value, temperature, hydraulic oil switching signal are set with determining its working condition when relevant parameter exceeds
Range is counted, entire car controller is then judged as foot brake or hand braking all or part of failure, then entire car controller is according to current vehicle
The speed of service and the direction of motion, calculate brake force, and the corresponding command is sent to electric machine controller, by electricity by specified criteria
Machine controller controls driving motor and generates the sizeable electromagnetic system power of and torque opposite with the direction of motion, reaches vehicle with this
The purpose of braking.
Mode of braking provided by the present invention have the characteristics that real-time detection, automatic decision, be swift in motion, brake force it is strong,
It can fully ensure that the vehicle and personnel safety in driving conditions.
Claims (1)
1. a kind of electric vehicle brake method, which is characterized in that entire car controller control during real time monitoring foot brake or
Pressure value signal, temperature and the hydraulic oil switching signal of person's hand braking system are braked with determining its working condition by detecting
System performance parameter, when parameter exceeds controlled range, entire car controller is judged as that braking system completely or partially fails, this
When entire car controller just according to running velocity and the direction of motion, calculate brake force by specified criteria, and brake force is sent out
It gives electric machine controller while opening braking mode, the output generation that motor is controlled by electric machine controller is opposite with the direction of motion
Electromagnetic system power, reversed electromagnetic braking power acts between motor and transmission device, transmission device is embraced, electronic to realize
Automobile is braked.
