Abstract
The invention is aimed at providing a storage battery power-lack proof control method based on keyless start system, for preventing generation of storage battery power-lack situation. The storage battery power-lack proof control method based on keyless start system in the invention specifically comprises the following steps: in flameout state of a car, a keyless start control module communicates with a car body control module for obtaining voltage of the storage battery, if the voltage of the storage battery is lower than a predetermined low threshold voltage (Vlow), the keyless start control module starts the engine and notifies an engine control module to set the working state of the engine as a state for charging the storage battery; and after the working time of duration of the engine exceeds a predetermined time (T), the keyless start control module stops the engine. The method can start the engine to charge the storage battery automatically when electric quantity of the storage battery is low, so the method avoids situation of storage battery power-lack, brings convenience to users and prolongs service life of the storage battery.
Description
Technical field
The invention belongs to technical field of automotive electronics, specially refer to a kind of electricity storage preventing pond power shortage control method based on no key start-up system.
Background technology
A lot of electrical equipment of automobile all are by battery-driven, for example Der Scheinwerfer mit FernlichtAbblendlichtStandlicht, sound equipment, starter etc.Close vehicle mounted electrical apparatus if the user forgets after parking, after perhaps the user parks vehicle for a long time, the situation of discharged or defective battery just possibly occur.When the user prepares to drive again, can't drive starter because the surplus electricity of storage battery is not enough, therefore can't start vehicle, this not only can bring very big inconvenience to the user, performance that also can the heavy damage storage battery.
Summary of the invention
The objective of the invention is to propose a kind of electricity storage preventing pond power shortage control method, to prevent the situation of discharged or defective battery based on no key start-up system.
Electricity storage preventing pond power shortage control method based on no key start-up system of the present invention specifically comprises the steps: not have key start-up control module under the automobile flameout state; Through with the Body control module communication to know battery tension; If battery tension is lower than predetermined low threshold voltage Vlow; No key start-up control module start the engine, and notice engine control module engine behavior is set to battery state of charge; After the engine operation time length surpassed schedule time T, no key start-up control module killed engine.
Further; No key start-up control module through with the auto meter communication to know fuel tank fuel quantity; Have only when fuel tank fuel quantity is higher than fuel allowance, no key start-up control module is start the engine, even otherwise also start the engine not of accumulator feeding; Because of causing fuel tank fuel quantity not enough, battery charge makes troubles preventing to the car owner.
Further, behind engine starting, Body control module is monitored vehicle door status in real time, and when car door was opened, Body control module sent information to no key start-up control module, and no key start-up control module kills engine, to guarantee the safety of automobile.
Specifically, said schedule time T is 15～25 minutes, and the time is too short, can't be the storage battery full charge, and overlong time can waste energy again.
Specifically, said fuel allowance is 10%～15% of the fully loaded oil mass of fuel tank, to guarantee that fuel tank fuel quantity still can satisfy certain continuation of the journey mileage after being battery charge.
Specifically, under the said battery state of charge, engine speed is 2000 rev/mins, under the prerequisite that guarantees certain generating capacity, makes engine operation as much as possible between high efficient area.
Electricity storage preventing pond power shortage control method based on no key start-up system of the present invention can be when accumulator electric-quantity be low, and automatic actuation engine is a battery charge, thereby has avoided the situation of discharged or defective battery, has made things convenient for the user and has improved storage battery service life.
Description of drawings
Fig. 1 is the diagram of circuit of the electricity storage preventing pond power shortage control method based on no key start-up system of the present invention.
The specific embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are done further to specify.
Embodiment 1:
As shown in Figure 1; The electricity storage preventing pond power shortage control method based on no key start-up system of present embodiment specifically comprises the steps: not have key start-up control module under the automobile flameout state; Through with the Body control module communication to know battery tension; And through with the auto meter communication to know fuel tank fuel quantity, only when battery tension is lower than predetermined low threshold voltage Vlow and fuel tank fuel quantity and is higher than fuel allowance, no key start-up control module ability start the engine; And notify the engine control module engine behavior to be set to battery state of charge, otherwise driving engine keeps flameout state; After the engine operation time length surpassed schedule time T, no key start-up control module killed engine.
Behind engine starting, Body control module is monitored vehicle door status in real time, and when car door was opened, Body control module sent information to no key start-up control module, and no key start-up control module kills engine, to guarantee the safety of automobile.
Specifically, above-mentioned schedule time T is 20 minutes, and predetermined low threshold voltage Vlow is 11V, and fuel allowance is 10% of the fully loaded oil mass of fuel tank, and under battery state of charge, engine speed is 2000 rev/mins.
