Referring to fig. 1, a preferred embodiment of the present invention provides a method for increasing a driving range of a vehicle, applied to a driving motor controller MCU, including the steps of:
s101: when a braking signal is detected during the running of the vehicle, the required power of the low-voltage power consumption device and the allowable feedback power of the storage battery are obtained.
The required power may refer to a rated power of the power consumption device, and the allowable feedback power of the storage battery refers to a power that can be recovered by the storage battery at the current power.
Optionally, after the braking signal is detected, before the required power of the low-voltage power consuming device and the allowable feedback power of the storage battery are acquired, the method further includes: and judging that the low-voltage power consumption device is in a working state.
And the MCU executes S102 when judging that the low-voltage power consumption device is in the working state.
S102: and determining the actual generating power of the driving motor according to the required power of the low-voltage power consumption device and the allowable feedback power of the storage battery.
Optionally, if the MCU determines that the low-voltage power consuming device is not in the operating state, the MCU may determine the actual generated power of the driving motor according to the allowable feedback power of the storage battery.
Optionally, determining the actual generated power of the driving motor according to the demanded power of the low-voltage power consumption device and the allowable feedback power of the storage battery includes:
determining the maximum generating power of the driving motor according to the opening information of the brake pedal and the rotating speed information of the driving motor;
if the maximum generating power is smaller than the sum of the allowed feedback power of the low-voltage power consumption device and the storage battery, determining the actual generating power of the driving motor as the maximum generating power;
and if the maximum generated power is larger than or equal to the sum of the allowed feedback power of the low-voltage power consumption device and the storage battery, determining that the actual generated power of the driving motor is equal to the sum of the allowed feedback power of the low-voltage power consumption device and the storage battery.
The MCU can determine the maximum generating power of the driving motor according to a corresponding relation table of prestored brake pedal opening information, prestored driving motor rotating speed information and prestored maximum generating power of the driving motor and according to the brake pedal opening information and the driving motor rotating speed information. For example, when the MCU acquires the first opening degree information of the brake pedal and the first rotation speed information of the driving motor, the MCU may determine the first maximum generated power of the driving motor according to the correspondence table. If the maximum generating power of the driving motor is smaller than the sum of the allowed feedback power of the low-voltage power consumption device and the storage battery, the MCU controls the driving motor to generate power according to the maximum generating power, the generated electric energy can be simultaneously utilized by the low-voltage power consumption device and the storage battery, and energy waste is avoided. If the maximum generating power of the driving motor is larger than or equal to the sum of the allowed feedback powers of the low-voltage electric consuming device and the storage battery, the MCU controls the driving motor to generate power according to the fact that the actual generating power of the driving motor is equal to the sum of the allowed feedback powers of the low-voltage electric consuming device and the storage battery, and therefore the situation that the driving motor generates power according to the maximum generating power and the generated electric energy cannot be simultaneously utilized by the low-voltage electric consuming device and the storage battery is avoided, and energy waste is caused.

In the running process of the vehicle, when a braking signal is detected, the required power of a low-voltage power consumption device and the allowable feedback power of a storage battery are obtained, the driving motor is controlled to generate power according to the required power of the low-voltage power consumption device and the allowable feedback power of the storage battery, and the actual power generation power is supplied to the low-voltage power consumption device and the storage battery, so that the consumption of the low-voltage power consumption device on the electric quantity of the storage battery can be reduced or even avoided. And the situation that the electric quantity of the storage battery is excessively consumed by the low-voltage electric consumption device and the direct-current converter continuously converts the high-voltage electricity in the power battery into the low-voltage electricity in the storage battery is avoided. And then also can avoid because the electric quantity in the power battery is constantly consumed, leading to the vehicle mileage to reduce, influence user experience's emergence.
Optionally, supplying power to the low voltage power consumer and/or the battery comprises:
when the actual generated power of the driving motor is determined to be smaller than the required power of the low-voltage power consumption device, supplying power to the low-voltage power consumption device according to the actual generated power;
when it is determined that the actual generated power of the drive motor is greater than or equal to the required power of the low-voltage power consumption device and less than the sum of the allowable feedback powers of the low-voltage power consumption device and the storage battery, power is supplied to the low-voltage power consumption device according to the required power, and generated power other than the required power is supplied to the storage battery.
And when the MCU determines that the actual generated power of the driving motor is smaller than the required power of the low-voltage power consumption device, the MCU supplies power to the low-voltage power consumption device according to the actual generated power, but the actual generated power is not enough to meet the required power of the low-voltage power consumption device. At this time, the storage battery may provide a part of discharge power to supply power to the low-voltage power consumption device, that is, the required power of the low-voltage power consumption device is the actual power generation power of the driving motor plus the discharge power of the storage battery, so that the consumption of the storage battery by the low-voltage power consumption device may be reduced, the consumption of the power battery in the vehicle may be reduced, and the driving range of the vehicle is increased.
When the MCU determines that the actual power generation power of the driving motor is greater than or equal to the required power of the low-voltage power consumption device and less than the sum of the allowed feedback powers of the low-voltage power consumption device and the storage battery, the electric quantity provided by the MCU to the low-voltage power consumption device can meet the required power of the low-voltage power consumption device, and the low-voltage power consumption device can be prevented from consuming the electric quantity in the storage battery. And the MCU can also supply the generated power except the required power to the storage battery, so that the electric quantity in the storage battery is kept in a better state, the discharge times of the storage battery can be increased, the consumption of the electric quantity of a power battery in the vehicle is reduced or even avoided, and the driving mileage of the vehicle is further improved.
Optionally, the low voltage power consumer device comprises at least one of: an air conditioning system and a DC converter. And when the MCU determines that the actual generated power of the driving motor is greater than the required power of the air conditioning system and less than the sum of the required power of the air conditioning system and the required power of the direct current converter, the MCU supplies power to the air conditioning system according to the required power of the air conditioning system and supplies generated power except the required power of the air conditioning system to the direct current converter. If the generated power except the power meeting the demand of the air conditioning system is not enough to meet the demand of the direct current converter, the storage battery provides a part of discharge power to the direct current converter so as to meet the demand of the direct current converter; when the actual power generation power of the driving motor is determined to be smaller than the required power of the air conditioning system, the MCU supplies power to the air conditioning system according to the actual power generation power, and the storage battery provides discharge power to the air conditioning system and the direct current converter so as to respectively meet the required power of the air conditioning system and the direct current converter, so that the consumption of the air conditioning system and the direct current converter on the electric quantity of the storage battery can be reduced.

When a (i) < c (i), the actual power of the air conditioning system is c (i) ═ a (i) + b (i), namely the actual generated power of the motor is not enough to meet the required power of the air conditioning system, and the storage battery needs to provide a part of discharge power to meet the required power of the air conditioning system; when a (i) ≧ c (i) and c (i) < c (i), the actual power of the air-conditioning system (c) (i) ≧ a (i) -b (i) -d (i), namely the MCU can supply additional generated power to the storage battery and the dc converter when the required power of the air-conditioning system is satisfied; when a (i) ≧ c (i) and c (i) ≧ c (i), i.e. the actual generated power of the driving motor is greater than the sum of the required power of the air conditioning system, the maximum allowed feedback power of the storage battery and the dc converter, c (i) ≧ a (i) (-a) (i) (-b) (i) (-d (i)), the air conditioning system can adjust the current time interval gear by Pulse Width Modulation (PWM) to further increase the allowed power of the air conditioning system, the air conditioning system can store the energy of the driving motor which is greater than the sum of the three in the water heating system, i.e. the actual power of the air conditioning system ≧ c (i) (+ the energy storage power of the water heating system, the power consumption of the air conditioning system and the dc converter in the next discharging stage of the storage battery can be reduced, therefore, the driving mileage of the vehicle is improved, and the user experience is improved.
