Abstract
The invention discloses a method for starting an electric vehicle safely, which comprises the following steps: collecting a starting signal by a vehicle controller, wherein a switching signal, a gear signal and a braking signal of a key are collected; defining a neutral gear flag (N_to_D_check_flag), wherein the neutral gear flag (N_to_D_check_flag) is set to be 1, otherwise, the flag (N_to_D_check_flag) is 0; judging whether a high-voltage bus is electrified according to the collected signals, if yes, performing the next step, if not, returning to the first step; electrifying a motor; judging whether the gear signal is a neutral gear when a driver opens the key, if yes, performing the next step, if not, performing judgment continuously; setting the flag (N_to_D_check_flag) to be 0; judging whether the gear signal is the neutral gear, if yes, returning to the step of judging continuously, if not, performing the next step; and starting a motor finally. According to the method, the vehicle controller monitors the states of the switching signal and the gear signal of the key so as to determine whether the motor can be started.
Description
Technical field
The present invention relates to a kind of electronlmobil startup method.Particularly relate to a kind of state, determine whether a kind of electronlmobil safe starting method of starter motor through entire car controller monitoring key switch and gear signal.
Background technology
Along with fast development of Chinese economy, people's living standard is increasingly high, the purchasing power of automobile is also had greatly promote, and makes the energy of China and environmental problem increasingly serious.Proceeding from actual conditions in the country needs us to strengthen the R&D intensity to electronlmobil.Because electronlmobil is directly to power on to motor through key switch, can start.When if chaufeur is not noticed range state, just start key, vehicle advances under the situation that chaufeur is not ready for or retreats, as easy as rolling off a log initiation traffic accident.If chaufeur is run into some maloperations that driving switch also can cause motor because of carelessness in startup procedure in addition, has great potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention is, provide a kind of can either realize motor start a kind of electronlmobil safe starting method that can guarantee vehicle and driver safety again rapidly and accurately.
The technical scheme that the present invention adopted is: a kind of electronlmobil safe starting method comprises the steps:
1) entire car controller is gathered actuation signal;
2) neutral zone bit N_to_D_check_flag of definition;
3) judging according to the actuation signal of being gathered whether high-voltage bus powers on, is then to get into next step, otherwise returns the 1st step;
4) power on to motor;
When 5) chaufeur is opened key, judge whether gear signal is neutral gear, is then to get into next step, otherwise continue to judge;
6) establishing zone bit N_to_D_check_flag is 0;
7) judge whether gear signal is neutral gear, be then to return to continue to judge, otherwise get into next step;
8) starter motor finishes.
The described actuation signal of step 1 comprises on-off signal, gear signal and the speed-slackening signal of gathering key.
The described definition neutral of step 2 zone bit N_to_D_check_flag is, when gear signal was neutral when in entire car controller, setting chaufeur and opening key, zone bit N_to_D_check_flag was 1, otherwise zone bit N_to_D_check_flag is 0.
The described starter motor of step 8 is to gather forward gear and backward gear signal at the same time, and when the both is correct, just allows to start starter motor.
A kind of electronlmobil safe starting method of the present invention, the state through entire car controller monitoring key switch and gear signal determines whether starter motor.Has only when key signal and gear signal meet the demands simultaneously just starter motor.In order to prevent driver's maloperation, entire car controller need limit the response of motor to gear signal by brake signal when putting into gear.
Description of drawings
Fig. 1 is the diagram of circuit of control method of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing a kind of electronlmobil safe starting method of the present invention is made detailed description.
The electronlmobil safe starting method is characterized in that, comprises the steps:
1) entire car controller is gathered actuation signal;
Described actuation signal comprises on-off signal, gear signal and the speed-slackening signal of gathering key.
2) neutral zone bit N_to_D_check_flag of definition;
Described definition neutral zone bit N_to_D_check_flag is, when gear signal was neutral when in entire car controller, setting chaufeur and opening key, zone bit N_to_D_check_flag was 1, otherwise zone bit N_to_D_check_flag is 0.
3) judging according to the actuation signal of being gathered whether high-voltage bus powers on, is then to get into next step, otherwise returns the 1st step;
4) power on to motor;
When 5) chaufeur is opened key, judge whether gear signal is neutral gear, is then to get into next step, otherwise continue to judge;
6) establishing zone bit N_to_D_check_flag is 0;
This moment the driver hang forward gear still hang fall back the retaining all can't start automobile.Does having only the driver to hang to make the return trip empty retaining, entire car controller to collect key simultaneously open signal and neutral signal M_to_D_check_flag and just can start automobile at 1 o'clock (is it right?).
7) judge whether gear signal is neutral gear, be then to return to continue to judge, otherwise get into next step;
8) starter motor finishes.
Described starter motor is to gather forward gear and backward gear signal at the same time, and when the both is correct, just allows to start starter motor.
Claims (4)
