Step 2: when vehicle deviates this lane, if driver beats turn signal lane-change according to normal operating in advance, system is not issued Warning note, if unconscious this lane of deviation of driver, the buzzer in system will issue rapid alarm, and adjoint system refers to Show that lamp flashes；

Step 3: before vehicle will enter minimum safe distance, system can according to what is collided on vehicle running path Energy property reminds the possible risk of collision of driver by vision, audible means, driver is reminded to take timely measure, to avoid The generation of collision accident improves the safety of driving；

Step 4: if driver is unaware that vehicle will collide, the input that is provided by camera and HMI device and The existing torque demand that VCU equipment provides, controller judge that vehicle needs pattern switching, i.e. reduction torque by scene analysis Or emergency braking, demand torque is sent at this time to VCU equipment to vehicle direct torque, reaches the limitation torque peak in drive mode Value and slope increase sliding brake function torque and active brake torque in the braking mode, and guarantee traffic safety.

Technical field:

The present invention relates to a kind of for new energy and the work side of the energy-saving safe system that has energy recovery function vehicle Method belongs to new-energy automobile energy-saving safe technology.

Background technique:

For actual cities jam road operating condition, bus has vehicle close to risk of collision in the process of moving, but takes charge of Machine is also maintained at open out or keeps the situation of current vehicle speed, this not only causes driving danger that the energy content of battery can also be lost.Therefore Wish to propose that a kind of scheme can be limited by system activly request and be turned round when that will collide but driver does not also take effective brake Slow down or brakes, it is ensured that traffic safety, and the energy content of battery is effectively saved, increase course continuation mileage.

Summary of the invention:

The present invention is to provide one kind in order to solve the above-mentioned problems of the prior art for new energy and have energy Recycle the working method of the energy-saving safe system of function vehicle.

The technical solution adopted in the present invention has: it is a kind of for new energy and have energy recovery function vehicle safety save The working method of energy system, wherein energy-saving safe system includes camera, HMI device and VCU equipment, and steps are as follows:

Step 1: with high performance forward sight camera be main detecting sensor, based on machine vision technique detect and with Track lane line, judges whether vehicle has the danger for deflecting away from lane in conjunction with driver characteristics, provides sound by HMI device for driver Sound, light warning；

Step 2: when vehicle deviates this lane, if driver beats turn signal lane-change according to normal operating in advance, system is not Warning note is issued, if unconscious this lane of deviation of driver, the buzzer in system will issue rapid alarm, and adjoint system System indicator light flashes；

Step 3: before vehicle will enter minimum safe distance, system collides according on vehicle running path A possibility that, the possible risk of collision of driver is reminded by vision, audible means, driver is reminded to take timely measure, with The generation for avoiding collision accident improves the safety of driving；

Step 4: if driver is unaware that vehicle will collide, pass through the input of camera and HMI device offer And the existing torque demand that VCU equipment provides, controller are judged that vehicle needs pattern switching, that is, are reduced by scene analysis Torque or emergency braking send demand torque to VCU equipment to vehicle direct torque at this time, reach to limit in drive mode and turn round Square peak value and slope increase sliding brake function torque and active brake torque in the braking mode, and guarantee traffic safety.

The invention has the following beneficial effects:

1, the present invention is directed to new energy and the energy-saving safe system for having energy recovery function vehicle can be promoted greatly Traffic safety；
