Wherein, under the Sport mode to the mode control vehicle power of satisfying vehicle dynamic nature demand includes: compared with the driving torque corresponding to the same opening degree in the Normal mode, the driving torque of the accelerator pedal is larger so as to enhance the power. In the B mode, the vehicle power is controlled in an economical manner to recover energy, and the B mode comprises the following steps: compared with the Normal mode, the brake pedal has larger corresponding recovery torque to enhance energy recovery.

In this example, the first set electric quantity value and the second set electric quantity value are respectively taken as 28% and 92% of the rated electric quantity of the battery. And judging the open state of the sports mode key and the B mode key.
And S130, controlling the electric automobile to enter one of the driving modes according to the judgment result.
Referring to the flowchart in fig. 2, corresponding to the specific example described in steps S120 and S130, the method for controlling the electric vehicle to enter one of the four driving modes in the present embodiment includes:
and when the SOC is less than 28%, if the B mode key is judged to be opened, enabling the vehicle to be in the B mode, and otherwise, enabling the vehicle to be in the Normal mode. In the state, the sports mode key is closed, the sports mode key is invalid, and the vehicle is controlled not to enter the sports mode and the sports + B mode and only to be in the Normal mode or the B mode;
when the SOC is more than or equal to 28% and less than or equal to 92%, the electric automobile can enter a corresponding mode according to the opening state of the two keys, and the method comprises the following steps: when the B mode key and the sports mode key are not opened, the vehicle is in a Normal mode; when the B mode key is judged to be turned on, the vehicle is in the B mode; when the sports mode key is judged to be turned on, the vehicle is in a sports mode; when the B mode key and the sports mode key are both turned on, the vehicle is in a sports + B mode;
when the SOC is larger than 92%, if the sports mode key is turned on, the vehicle is in a sports mode, otherwise, the vehicle is in a Normal mode. In this state, the B mode key is turned off, the B mode key is invalid, and the vehicle is controlled not to enter the B mode or the Sport + B mode but only to be in the Normal mode or the Sport mode.
Therefore, the invention can control the vehicle to run in various modes including entering the sports mode and the B mode according to the opening states of the sports mode key and the B mode key, thereby ensuring the high driving efficiency, meeting the driving experience of different users, strengthening the energy recovery on the premise of meeting the driving pleasure of the sports mode of the users when entering the sports mode and the B mode, and equivalently improving the cruising ability of the electric vehicle in the sports mode. In addition, the residual capacity of the power battery is considered at the same time, the vehicle is controlled to run in multiple modes by reasonably applying the switching condition, the over-discharge or over-charge of the battery is avoided, the service life of the battery can be effectively prolonged, and the use cost of the vehicle is reduced.
Next, a method for controlling an electric vehicle in the Sport + B mode will be described in further detail with reference to the schematic diagram shown in fig. 3, where the method for controlling an electric vehicle in the Sport + B mode includes the following steps:
and S310, judging that the opening degree of an accelerator pedal is larger than 0, namely when the vehicle is in the state that the accelerator pedal is pressed down, controlling the power of the vehicle in a Sport mode to enhance the power.
S320, when the accelerator pedal opening is equal to 0 and the vehicle speed is greater than 0, that is, when the vehicle is in a slip state in which neither the accelerator pedal nor the brake pedal (for simplicity of description, the accelerator pedal and the brake pedal will be collectively referred to as a speed control pedal hereinafter) is depressed during running, and when the vehicle is in a speed control pedal opening of 0, that is, when the speed control pedal is released, energy is recovered according to the following rule:
first energy recovery rule: executing the control of the vehicle power and the energy recovery in the mode B from the moment when the opening degree of the speed control pedal is 0, namely from the moment when the speed control pedal is released; when the speed control pedal is depressed at any time, the present step is ended, and the process proceeds to step S310 or S330 accordingly.
Second energy recovery rule: controlling the power of the vehicle in a Normal mode from the time when the opening degree of the speed control pedal is 0, namely from the time when the speed control pedal is released to a first set time t1, and gradually increasing the control energy recovery intensity from the time t1 until the control and energy recovery of the power of the vehicle are carried out in a B mode; when the speed control pedal is depressed at any time, the present step is ended, and the process proceeds to step S310 or S330 accordingly.
Third energy recovery rule: monitoring the speed reduction rate (the speed reduction rate, namely the speed reduction speed of the vehicle, which may correspond to the situation that the vehicle is in a climbing, horizontal running or downhill) in real time from the moment that the opening degree of a speed control pedal is 0, namely from the moment that the speed control pedal is released, if the speed reduction rate is greater than a certain threshold (indicating that the vehicle may be in the climbing state), controlling the power of the vehicle in a Normal mode, and if the speed reduction rate is less than the certain threshold, controlling the energy recovery intensity to gradually increase until the control and the energy recovery of the power of the vehicle are carried out in a B mode; when the speed control pedal is depressed at any time, the present step is ended, and the process proceeds to step S310 or S330 accordingly.
The three energy recovery rules can be selected and used, the third energy recovery rule can be respectively combined with the first two energy recovery rules, and when the three energy recovery rules are combined and used, the priority of the third energy recovery rule is higher than that of the first two energy recovery rules.
And S330, judging that the opening degree of the brake pedal is larger than 0, namely when the vehicle is in the state that the brake pedal is pressed down, controlling the power of the vehicle in a mode B to enhance energy recovery.
And, it can be further judged whether the brake pedal opening degree > 0 is in the above-mentioned t1 time period, if yes, the vehicle power is controlled in the Normal mode until the time t1, and the energy recovery intensity is gradually increased from the time t1 until the vehicle power is controlled and the energy is recovered in the B mode.
From the above, when the electric vehicle is switched to enter the Sport + B mode, the energy recovery of the mode in the B mode is not executed when the user presses the accelerator pedal, or slides or brakes within a time period t1 (including a vehicle sliding state and a braking state), and the vehicle correspondingly and correspondingly performs vehicle power control in the Sport mode or the Normal mode, so that the vehicle power demand is preferentially met when the electric vehicle is accelerated or switched to slide or brake in a short time, and the user has better driving experience of motion;
when the vehicle slides for more than t1 time or the brake pedal is pressed for more than t1 time, the energy recovery in the mode B is executed, and the time t1 after the pedal is released is already exceeded, so that the driving characteristics of the user for switching the brake pedal in the short time are not influenced, and the energy recovery in the mode B is enhanced, and the driving experience of the whole sporty feeling of the user is not reduced.
Therefore, the vehicle control in the Sport mode of the invention is equivalent to strengthening energy recovery and improving the cruising ability of the electric vehicle in the Sport mode on the premise of meeting the driving pleasure of the user in the Sport mode.
In the step S330, the t1 may be replaced by a second set time t2, where the t1 and the t2 may be equal or different.
