Example (b):
in order to solve the above technical problem, the present invention discloses a vehicle control method, as shown in fig. 1, fig. 1 is a flowchart of a vehicle control method according to an embodiment of the present invention, and the method includes:
and S100, acquiring the current running state of the storage battery of the vehicle.
Specifically, in an implementable solution, the current operating state of the battery of the vehicle may include, but is not limited to, the current charge of the battery, the current operating environment temperature of the battery, and the current wear data of the battery.
Specifically, the electric quantity sensor (the electric quantity sensor is a detection device which can sense the information of the measured electric quantity and convert the sensed information into an electric signal or other information in a required form according to a certain rule to output so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like) can be obtained through the automobile central controller, the electric quantity sensor is the primary link for realizing automatic detection and automatic control, and is also a device which converts the measured electric quantity parameters (such as current, voltage, power, frequency, power factor and other signals) into direct current and direct current voltage and isolates and outputs analog signals or digital signals to obtain the current operating environment temperature of the storage battery detected by the temperature sensor, and storing the acquired current electric quantity of the storage battery and the acquired current operating environment temperature of the storage battery.
Further, the wear data includes, but is not limited to, one or more of a present allowed charging voltage of the battery or a present allowed discharging current of the battery or a present internal resistance of the battery. Specifically, the current allowable charging voltage of the storage battery calculated and stored by the charging voltage calculation module (stored in the vehicle) may be directly obtained by the vehicle central controller, or the current allowable charging voltage of the storage battery may be calculated by the vehicle central controller according to the obtained current internal resistance value and the obtained current voltage value after the current internal resistance value of the storage battery detected by the resistance sensor (the sensor that converts non-electrical physical quantities such as displacement, force, pressure, acceleration, torque, and the like into resistance value changes) is obtained first. It is understood that, since the allowable charging voltage of the secondary battery will decrease as the internal resistance increases, the current allowable charging voltage of the secondary battery can be calculated based on the correspondence between the increase value of the internal resistance and the decrease value of the allowable charging voltage, and the obtained current internal resistance value of the secondary battery. Wherein the calculated current allowed charging voltage may be an estimated value. The correspondence between the internal resistance increase value and the decrease value of the allowable charging voltage may be obtained from a plurality of tests and set in advance. Further, the charging voltage calculation module may also calculate and store the current allowable charging voltage of the storage battery according to the above manner.
Further, the current of the storage battery detected by the current sensor can be acquired by the automobile central controller, and the current of the storage battery is used as the current allowable discharging current of the storage battery, or in order to avoid the power shortage of the storage battery, after a preset value is subtracted from the acquired current of the storage battery, the calculation result is used as the current allowable discharging current of the storage battery.
S102, determining whether the current operation state of the storage battery meets a preset power supply condition or not according to the current operation state of the storage battery.
Specifically, if the current operating state of the storage battery meets the preset power supply condition, step S104 is executed. Further, in an implementable scheme, determining whether the current operating state of the storage battery meets a preset power supply condition according to the current operating state of the storage battery may be implemented according to the steps shown in fig. 3:
and S1020, judging whether the current electric quantity of the storage battery is larger than a preset electric quantity threshold value.
It can be understood that the obtaining of the current electric quantity of the storage battery can be implemented according to the above-described manner, and is not described herein again. The preset electric quantity threshold may be, but is not limited to, an electric quantity value such as 5V, 8V, and the like, and may be specifically set according to an actual requirement, and is not specifically limited herein. Specifically, when the current electric quantity of the storage battery is greater than the preset electric quantity threshold, step S1022 is executed.
And S1022, determining that the current electric quantity of the storage battery meets a preset power supply electric quantity condition.
And S1024, judging whether the current operating environment temperature of the storage battery is greater than a preset charging environment temperature threshold value.
It is understood that if the charging temperature is too low, the charging capacity of the storage battery is too poor, and a situation that the charging speed is lower than the discharging speed may occur, so that the storage battery is easy to lose power, and therefore, the current operating environment temperature of the storage battery needs to be considered. Specifically, the obtaining of the current operating environment temperature of the storage battery may be implemented according to the manner described above, and is not described herein again. The preset charging environment temperature threshold may be, but is not limited to, 30 ℃, 32 ℃, and the like, and may be specifically set according to actual requirements, and is not specifically limited herein. When the preset charging environment temperature threshold is set, the allowable charging temperature of the storage battery may be used as a reference. Specifically, when the current operating environment temperature of the storage battery is greater than the preset charging environment temperature threshold, step S1026 is executed.
And S1026, determining that the current operating environment temperature of the storage battery meets a preset power supply environment condition.
S1028, determining the remaining life cycle of the storage battery according to the current loss data of the storage battery.
Specifically, the obtaining of the current wear data of the storage battery may refer to the above description, and is not described herein again.
In some implementations, the present life cycle of the battery may be calculated according to the present allowable charging voltage of the battery and/or the present allowable discharging current of the battery and/or the present internal resistance of the battery; and taking the current life cycle of the storage battery as the residual life cycle of the storage battery.
It can be understood that, as the service life of the storage battery increases, the allowable charging voltage of the storage battery decreases, the internal resistance of the storage battery increases, and the current allowable discharging current of the storage battery is also affected by the decrease of the current allowable charging voltage, so that the change of each index in the storage battery affects the remaining life of the storage battery. Specifically, the current life cycle of the storage battery may be calculated according to a corresponding relationship between a decrease value of an allowable discharge voltage of the storage battery, an increase value of an internal resistance of the storage battery, an allowable charge current value of the storage battery, and a life loss time of the storage battery, or a single mapping relationship between each index and the life loss time of the storage battery, and the calculated current life cycle of the storage battery may be used as the remaining life cycle of the storage battery. It can be understood that the corresponding relationship between the reduction value of the allowable discharge voltage of the storage battery, the increase value of the internal resistance of the storage battery, the allowable charge current value of the storage battery and the life consumption time of the storage battery, or the single mapping relationship between each index and the life consumption time of the storage battery, may be obtained according to a plurality of test statistics and stored in advance.
And S1030, judging whether the residual life cycle of the storage battery is larger than a scrapped life cycle threshold value. Specifically, when the remaining life cycle of the storage battery is greater than the scrapped life cycle threshold, step S1032 is executed.
S1032, determining that the residual life cycle of the storage battery meets a preset power supply life cycle condition.
It can be understood that the scrapped life cycle threshold value can be set according to actual requirements, when the remaining life cycle of the storage battery is greater than the scrapped life cycle threshold value, it is indicated that the storage battery can be continuously used, and at this moment, it is determined that the remaining life cycle of the storage battery meets the preset power supply life cycle condition.
S1034, judging whether the storage battery simultaneously meets a preset power supply electric quantity condition, a preset power supply environment condition and a preset power supply life cycle condition.
Specifically, when the storage battery simultaneously satisfies the preset power supply capacity condition, the preset power supply environment condition, and the preset power supply life cycle condition, step S1036 is executed.
And S1036, determining that the storage battery meets a preset power supply condition.
And S104, acquiring the current running fuel injection quantity of the vehicle.
Specifically, the central controller of the vehicle can calculate the fuel injection time, i.e., the fuel injection quantity, required by the engine in different states according to signals transmitted by the engine speed, the vehicle speed, the throttle position, the water temperature, the air flow meter or the pressure sensor, the air inlet temperature, the atmospheric pressure sensor, the exhaust gas sensor, and the like, and the feedback of the exhaust gas sensor, and the like.
And S106, judging whether the current running fuel injection quantity of the vehicle is larger than a preset fuel injection quantity threshold value.
Specifically, a preset fuel injection threshold may be set according to an actual requirement, if the current driving fuel injection of the vehicle is greater than the preset fuel injection threshold, step S108 is executed, and if the current driving fuel injection of the vehicle is not greater than the preset fuel injection threshold, step S110 is executed.
S108: and controlling a generator of the vehicle to reduce the voltage output outwards, and controlling the storage battery to increase the voltage output outwards.
It can be understood that, if the current driving fuel injection quantity of the vehicle is greater than the pre-fuel injection quantity threshold value, the vehicle may be in a starting state, an ascending slope state, a rapid acceleration state and the like, the output torque of the engine is higher, the fuel consumption is higher, the generator of the vehicle may be controlled to reduce the outward output voltage, and the storage battery may be controlled to increase the outward output voltage. Therefore, the torque consumed by the generator is reduced, and the load of the engine is reduced, so that the aim of reducing the oil consumption is fulfilled.
And S110, improving the output voltage of a generator of the vehicle, and controlling the engine of the vehicle to charge the storage battery.
It can be understood that when the current fuel injection amount of the vehicle is not greater than the preset fuel injection amount threshold, the vehicle may be in a running state such as downhill, deceleration or coasting, and the fuel injection amount of the engine is small, the output voltage of the generator of the vehicle may be increased, and the engine of the vehicle may be controlled to charge the battery, so that the battery can have enough electric quantity to supply power when the engine is in a running state with large fuel injection amount.
The invention determines the fuel injection quantity of the vehicle on the premise that the storage battery can provide the output voltage, and controls the storage battery to supply power and the generator to not supply power when the fuel injection quantity is large, thereby reducing the output power of the engine to the generator, reducing the load of the engine, improving the comprehensive fuel saving rate, reducing the energy consumption and the emission on the premise of avoiding the power feed of the storage battery, prolonging the service life of the power battery, and improving the electric quantity efficiency and the operation reliability of the power battery.
Further, fig. 2 shows a flowchart of another vehicle control method of the present invention, which includes:
and S200, acquiring the current running state of the storage battery of the vehicle.
S202, determining whether the current operation state of the storage battery meets a preset power supply condition or not according to the current operation state of the storage battery. It is understood that the detailed descriptions of steps S200-S202 may refer to the detailed descriptions of steps S100-S102, which are not repeated herein. Specifically, if the current operating state of the storage battery meets the preset power supply condition, step S204 is executed.
And S204, acquiring the current running state of the vehicle.
