Abstract
The invention provides a control method for preventing reversing of a blade electric vehicle during starting. The method comprises the following steps that if the electric blade vehicle is started and is in a forward gear and when a motor is in the negative rotating speed, a whole vehicle controller detects the state of the electric vehicle, and if the state of the electric vehicle meets the stall condition, the whole vehicle controller sends a signal to a motor controller to request the motor controller to carry out control of the zero rotating speed, the motor rotating speed is kept at zero, and the vehicle is kept still; and if not, a voice prompting system is started, and a driver is reminded to pay attention to driving. The invention further provides a control system for preventing reversing of the blade electric vehicle during starting. Driving of a user is facilitated, and the starting safety is guaranteed.

1, during electronlmobil uphill starting, certain hour is needed because throttle signal is input to Motor torque output, so require that driver by parking brake start assisting, must easily occur that vehicle falls back, and exists potential safety hazard when operation does not keep off;
2, frequent employing parking brake start assisting, not only easily causes brake facing to wear and tear and generates heat but also waste electric energy.
Summary of the invention
The technical problem to be solved in the present invention, is the control method and the system that provide a kind of pure electric automobile starting anti-retrogression, makes electronlmobil start to walk to fall back.
One of the present invention is achieved in that the control method of a kind of pure electric automobile starting anti-retrogression, comprises the steps:
During the starting of step 1, electronlmobil, if electronlmobil is in forward gear, and when negative rotating speed appears in motor, enter step 2; No, be then left intact;
Step 2, entire car controller detect electronic vehicle attitude, if electronic vehicle attitude meets stall condition, then entire car controller will send a signal to electric machine controller, and request electric machine controller carries out 0 rotating speed control, make motor speed keep 0 rotating speed, make vehicle keep static; Otherwise enter speech prompting system, remind chaufeur to note driving.
Further, described in described step 2, electronic vehicle attitude comprises: motor temperature, battery temperature and battery electric quantity.
One of the present invention is achieved in that the control system of a kind of pure electric automobile starting anti-retrogression, comprises as lower module:
Start judge module, during electronlmobil starting, if electronlmobil is in forward gear, and when negative rotating speed appears in motor, enter instruction control module; No, be then left intact;
Instruction control module, entire car controller detects electronic vehicle attitude, if electronic vehicle attitude meets stall condition, then entire car controller will send a signal to electric machine controller, request electric machine controller carries out 0 rotating speed control, makes motor speed keep 0 rotating speed, makes vehicle keep static; Otherwise enter speech prompting system, remind chaufeur to note driving.
Further, described in described instruction control module, electronic vehicle attitude comprises: motor temperature, battery temperature and battery electric quantity.
Tool of the present invention has the following advantages: the control method of a kind of pure electric automobile starting of the present invention anti-retrogression and system, by introducing 0 method for controlling number of revolution, vehicle is when uphill starting, the automatic anti-retrogression function of system, can avoid chaufeur by parking brake start assisting, has safety, energy-conservation feature, under the condition particularly frequently started to walk in ramp, improve uphill starting condition greatly, reduce driving difficulty, eliminate safe hidden trouble.
