In accordance with an embodiment of the present invention, there is provided a method embodiment of a method for controlling a hybrid vehicle launch, it being noted that the steps illustrated in the flowchart of the drawings may be carried out on a computer system such as a set of computer-executable instructions and that, although a logical sequence is illustrated in the flowchart, in some cases the steps illustrated or described may be carried out in a sequence different from that described herein.

As shown in fig. 1, which is a flowchart of a first embodiment of a control method for a hybrid vehicle launch start according to the application, as shown in fig. 1, the control method for the hybrid vehicle launch start includes the following steps:

step S102, collecting working condition information of the hybrid vehicle, wherein the working condition information comprises at least one of the following: the starting state of the hybrid vehicle and the effective continuous gear engaging times of the D gear;

step S104, judging whether the hybrid vehicle is in a catapult starting preparation state or not according to the working condition information;

and S106, if so, generating a first control strategy based on the effective continuous gear engaging times of the D gear, wherein the first control strategy comprises the steps of controlling the automatic parking system function of the hybrid vehicle to be closed, controlling the electronic parking system of the brake system to be unlocked, controlling the engine to start immediately and keep the starting state all the time, controlling the engine to keep outputting preset power, target rotating speed and target torque after starting, controlling the driving motor to output the torque required by the driver, controlling the drivability filter algorithm and the driving torque NVH control algorithm to stop calculating the torque of the driving motor, and controlling the driving motor and the water pump and the fan for cooling the generator to rotate at full speed.

Through the steps, the engine can be started in advance and prepared when the hybrid vehicle is started in a catapult mode, so that the engine can respond to the driving power request of the whole vehicle at any time, the cooling capacity as large as possible can be provided for the driving motor and the generator, the limitation of the power of the driving motor and the generator caused by over-temperature is avoided, the driving motor has enough available energy to complete high-power driving of the whole vehicle, the starting speed of the hybrid vehicle in the catapult mode is further improved, and the problem that the quick starting acceleration capacity of the dual-motor hybrid vehicle in the prior art is not strong is solved.

Alternatively, fig. 2 is a flowchart of a control method for hybrid vehicle launch starting according to a second embodiment of the present application, and as shown in fig. 2, the method for determining whether the hybrid vehicle is in a launch starting ready state according to the operating condition information includes the following steps:

step S21, judging whether the starting state of the hybrid vehicle is a starting success state;

step S22, under the condition that the starting state of the hybrid vehicle is a successful starting state, acquiring the interval time of adjacent D gear engaging operations;

step S23, judging whether the interval time meets a preset condition or not;

and step S24, if yes, preliminarily judging that the hybrid vehicle is in a launch starting preparation state.

Wherein the preset condition is set such that the interval time is less than 1.5 seconds. Specifically, when the hybrid vehicle is started successfully, the gear of the hybrid vehicle is a D gear, and a brake pedal of the hybrid vehicle is in a treading state, if a driver has at least two consecutive D gear engaging operations through a gear shifting device, and the interval time between the two D gear engaging operations is less than 1.5 seconds, the driver is considered to have the launch and start intention, and the hybrid vehicle is preliminarily determined to be in a launch and start ready state. Therefore, whether the hybrid vehicle has the launch starting requirement or not can be accurately judged.

Alternatively, fig. 3 is a flowchart of a control method for hybrid vehicle launch start according to the third embodiment of the application, and as shown in fig. 3, the control method for hybrid vehicle launch start further includes the following steps:

step S31, after the hybrid vehicle is preliminarily judged to be in a launch starting preparation state, judging whether the hybrid vehicle is in a static state within preset time;

step S32, if yes, determining that the hybrid vehicle is not in a launch starting preparation state;

step S33, if not, judging whether the gear of the hybrid vehicle is a D gear or not;

and step S34, determining that the hybrid vehicle is in a launch start ready state when the shift position is the D range.

In the present embodiment, the preset time is set to 30 seconds. Specifically, after the hybrid vehicle is preliminarily determined to be in the launch starting ready state, if the hybrid vehicle is still in the stationary state within 30 seconds, it is determined that the hybrid vehicle is not in the launch starting ready state, assuming that the driver has no launch starting intention. If the hybrid vehicle is not in a static state, but the gear of the hybrid vehicle is not the D gear, the driver is also considered to have no catapult starting intention, and the hybrid vehicle is determined not to be in a catapult starting preparation state. Therefore, whether the hybrid vehicle has the launch starting requirement or not can be further accurately judged.

Optionally, a first control strategy is generated based on the number of effective continuous gear engaging times of the gear D, and the first control strategy comprises the steps of determining a target rotating speed based on the number of effective continuous gear engaging times of the gear D; determining a target torque based on the target rotating speed and preset power; acquiring the accelerator opening and the vehicle speed of the hybrid vehicle; determining the torque required by the driver based on the opening degree of the accelerator and the vehicle speed; and generating a first control strategy based on the target rotating speed, the preset power, the target torque and the driver required torque. In the embodiment, the target rotating speed after the engine is controlled to start is larger as the number of times of effective continuous engaging in the D gear is larger, and the minimum target rotating speed of the engine in the series mode is controlled not to be lower than the target rotating speed of the engine when the number of times of effective continuous engaging in the D gear is two during driving. The preset power is 5kw, the target torque of the engine is obtained by calculation through the preset power (5 kw) and the target rotating speed, and the calculation formula is as follows:

target torque = preset power × 9550/target rotational speed

Specifically, after the hybrid vehicle is determined to be in the launch starting preparation state, the automatic parking system (EPB) function of the whole vehicle is automatically turned off, the EPB (electronic parking system) of the brake system is automatically unlocked, but if the EPB of the brake system is not automatically unlocked, the driver can turn on the EPB again through the EPB switch, and at the moment, the engine is controlled to be started immediately and the starting state is kept all the time. The engine maintains a mechanical power output of 5kw after starting. The engine speed is determined by the effective continuous engaging times of the D gear when the hybrid electric vehicle is in a launch starting preparation state, when the operation time between two continuous engaging D gears is less than 1.5 seconds, the effective continuous engaging times are two, and the engine speed is maintained at 2000 revolutions after the engine is started. And when the operation time between the continuous three D gear engaging is less than 1.5 seconds, the effective continuous engaging times are three times, and the rotating speed of the engine maintains 2500 revolutions after the engine is started. If the number of effective consecutive gear engagements is four or more, the engine speed is maintained at 3000 revolutions after the engine is started. In order to ensure that the driving motor has the torque response as fast as possible, the torque response of the driving motor is directly from a whole vehicle PedalMap table (namely the torque required by a driver is obtained by looking up a table through the opening degree of an accelerator and the vehicle speed), and meanwhile, a drivability filtering algorithm and a driving torque NVH control algorithm are controlled to stop calculating the torque of the driving motor. By means of the control, when the hybrid vehicle is subjected to launch starting, the engine can be started immediately and the working rotating speed of the engine is increased, so that the engine is guaranteed to have high power output speed to guarantee the power use of the driving motor, and the EPB is unlocked automatically by controlling the automatic function of the hybrid vehicle to be closed, so that the hybrid vehicle can be started quickly.

Alternatively, fig. 4 is a flowchart of a fourth embodiment of the control method for the hybrid vehicle launch start according to the application, and as shown in fig. 4, the control method for the hybrid vehicle launch start further includes the following steps:

step S41, under the condition that the hybrid vehicle is determined not to be in a launch starting preparation state, acquiring a first target rotating speed and a first target torque of an engine, and acquiring a second target torque of a driving motor;

and step S42, generating a second control strategy based on the first target rotating speed, the first target torque and the second target torque, wherein the second control strategy comprises the steps of controlling the engine to output the first target rotating speed and the first target torque, controlling the driving motor to output the second target torque and controlling the current state of the automatic parking system to be recovered to the state when the hybrid vehicle is not in the catapult starting preparation state.

In the embodiment, after the hybrid vehicle is determined not to be in the launch ready state, the hybrid vehicle is proved to have no launch requirement, and at the moment, the second control strategy is executed, so that the engine, the driving motor, the automatic parking system and other target devices of the hybrid vehicle can be controlled to execute the corresponding control strategy according to the actual situation of the hybrid vehicle.

Optionally, the obtaining of the first target rotating speed and the first target torque of the engine and the obtaining of the second target torque of the driving motor includes calculating the first target rotating speed and the first target torque based on a vehicle energy management algorithm, calculating the second target torque based on a drivability filter algorithm and a driving torque NVH control algorithm, and obtaining the first target rotating speed, the first target torque and the second target torque. In this embodiment, if the first target rotational speed and the first target torque calculated by the vehicle energy management algorithm are zero, the engine is controlled to stop.

The acquisition module 42 is configured to acquire operating condition information of the hybrid vehicle, where the operating condition information includes at least one of: the starting state of the hybrid vehicle and the effective continuous gear engaging times of the D gear; the judging module 44 judges whether the hybrid vehicle is in a launch starting preparation state or not according to the working condition information; the control module 46 generates a first control strategy based on the number of consecutive D-range effective gear engagements when the hybrid vehicle is in a launch ready state, wherein the first control strategy includes controlling an automatic parking system of the hybrid vehicle to be turned off, controlling an electronic parking system of a brake system to be unlocked, controlling an engine to be immediately started and to be kept in a starting state all the time, controlling the engine to be started and then to be kept outputting a preset power, a target rotating speed and a target torque, controlling a driving motor to be output a driver required torque, controlling a drivability filter algorithm and a driving torque NVH control algorithm to stop calculating a torque of the driving motor, and controlling a water pump and a fan for cooling the driving motor and the generator to be rotated at full speed.
