Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a control method, a control device, and a storage medium for a hybrid vehicle launch control. Background Art

[0002] As oil resources become increasingly scarce and facing increasingly stringent fuel consumption regulations, it is becoming increasingly costly and difficult for traditional pure internal combustion engine-driven vehicles to reduce fuel consumption. Hybrid vehicles, with the assistance of electric motors, have great potential to reduce fuel consumption. The P2 configuration represented by European manufacturers and the dual-motor planetary gear power split configuration represented by Toyota have all been mass-produced and have achieved good fuel consumption performance, winning the favor of the general public. However, both the P2 configuration and the power split configuration face many technical difficulties and technical barriers when applied in China, and the application of independent models has been relatively slow.

[0003] For the dual-motor hybrid configuration, when the vehicle is at medium and low speeds, the engine cannot directly drive the vehicle due to the vehicle speed ratio setting. Instead, the engine outputs torque and generates electricity through the generator. The electric power generated by the generator and the electric power from the power battery are jointly supplied to the drive motor, and the drive motor completes the vehicle's drive. Therefore, the available power of the drive motor is not only related to the discharge power of the power battery, but also to the power generated by the engine. For dual-motor hybrid vehicles, when the vehicle is stationary, the engine is often in a stopped state. When the driver starts with a large throttle, the engine needs to start from a stationary state before it can output the generator power. At the same time, the generator starting the engine process also consumes a certain amount of battery power, which will also cause the available power of the drive motor to decrease. Therefore, the starting and rapid acceleration capabilities of dual-motor hybrid vehicles are often not strong. Summary of the invention

[0028] According to an embodiment of the present invention, a method embodiment of a method for controlling a launch control of a hybrid vehicle is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] like Figure 1 FIG. 1 is a flow chart of a first embodiment of a control method for launching a hybrid vehicle according to the present application. Figure 1As shown, the control method for launching a hybrid vehicle includes the following steps:

[0030] Step S102, collecting the operating condition information of the hybrid vehicle, the operating condition information including at least one of the following: the starting state of the hybrid vehicle, the number of effective continuous shifts in the D gear;

[0031] Step S104, determining whether the hybrid vehicle is in a launch start preparation state according to the operating condition information;

[0032] Step S106, if yes, generates a first control strategy based on the number of effective consecutive gear shifts in D gear, wherein the first control strategy includes controlling the automatic parking system function of the hybrid vehicle to be turned off, controlling the electronic parking system of the braking system to be unlocked, controlling the engine to start immediately and keep it started, and controlling the engine to maintain output of preset power, target speed and target torque after starting, controlling the drive motor to output the torque required by the driver, controlling the drivability filtering algorithm and the drive torque NVH control algorithm to stop calculating the torque of the drive motor, and controlling the water pump and fan for cooling the drive motor and generator to rotate at full speed.

[0033] Through the above steps, the engine can be started and prepared in advance when the hybrid vehicle is launched, so that the engine can respond to the driving power request of the whole vehicle at any time, and can provide the greatest possible cooling capacity for the drive motor and the generator, avoiding the power limitation of the drive motor and the generator due to overheating, so that the drive motor has enough available energy to complete the high-power drive of the whole vehicle, thereby improving the starting speed of the hybrid vehicle when launching, and solving the problem of weak starting rapid acceleration capability of dual-motor hybrid vehicles in the prior art.

[0034] Optionally, Figure 2 FIG. 1 is a flow chart of a second embodiment of a control method for launching a hybrid vehicle according to the present application, as shown in FIG. Figure 2 As shown, judging whether the hybrid vehicle is in a launch start preparation state according to the operating condition information includes the following steps:

[0035] Step S21, determining whether the startup state of the hybrid vehicle is a startup success state;

[0036] Step S22, when the startup state of the hybrid vehicle is a successful startup state, obtaining the interval time of adjacent D gear shifting operations;

[0037] Step S23, determining whether the interval time meets a preset condition;

[0038] Step S24: if yes, preliminarily determine that the hybrid vehicle is in a launch start preparation state.

[0039] The preset condition is set to an interval time of less than 1.5 seconds. Specifically, when the hybrid vehicle is successfully started, the gear position of the hybrid vehicle is D gear, and the brake pedal of the hybrid vehicle is in a depressed state, if the driver has at least two consecutive D gear shifting operations through the shift device, and the interval between the two D gear shifting operations is less than 1.5 seconds, it is considered that the driver has a launch start intention, and the hybrid vehicle is preliminarily determined to be in a launch start preparation state. In this way, it can accurately determine whether the hybrid vehicle has a launch start requirement.

[0040] Optionally, Figure 3 FIG. 1 is a flow chart of a third embodiment of a control method for launching a hybrid vehicle according to the present application, as shown in FIG. Figure 3 As shown, the control method for launching a hybrid vehicle further includes the following steps:

[0041] Step S31, after preliminarily determining that the hybrid vehicle is in a launch start preparation state, determining whether the hybrid vehicle is in a stationary state within a preset time;

[0042] Step S32, if yes, determining that the hybrid vehicle is not in a launch start preparation state;

[0043] Step S33, if not, determining whether the gear position of the hybrid vehicle is D gear;

[0044] Step S34: when the gear position is the D gear, determining that the hybrid vehicle is in a launch start preparation state.

[0045] In this embodiment, the preset time is set to 30 seconds. Specifically, after the hybrid vehicle is initially determined to be in the launch start preparation state, if the hybrid vehicle is still stationary within 30 seconds, it is considered that the driver has no launch start intention, and it is determined that the hybrid vehicle is not in the launch start preparation state. If the hybrid vehicle is not stationary, but the gear position of the hybrid vehicle is not the D gear, it is also considered that the driver has no launch start intention, and it is determined that the hybrid vehicle is not in the launch start preparation state. In this way, it is possible to further accurately determine whether the hybrid vehicle has a launch start demand.

[0046] Optionally, a first control strategy is generated based on the number of effective continuous gear shifting times in D gear, including determining a target speed based on the number of effective continuous gear shifting times in D gear; determining a target torque based on the target speed and preset power; obtaining the throttle opening and vehicle speed of the hybrid vehicle; determining the driver's required torque based on the throttle opening and vehicle speed; and generating a first control strategy based on the target speed, preset power, target torque, and driver's required torque. In this embodiment, the more effective continuous gear shifting times in D gear, the greater the target speed of the engine after starting, and during driving, the minimum target speed of the engine in the series mode shall not be lower than the target speed of the engine when the number of effective continuous gear shifting times in D gear is two. Among them, the preset power is 5kw, and the target torque of the engine is calculated by the preset power (5kw) and the target speed, and the calculation formula is:

[0047] Target torque = preset power × 9550 / target speed

[0048] Specifically, after determining that the hybrid vehicle is in the launch start preparation state, the Autohold (automatic parking system) function of the vehicle is automatically turned off, and the EPB (electronic parking system) of the brake system is automatically unlocked. However, if the EPB of the brake system is not automatically unlocked, the driver can turn on the EPB again through the EPB switch, and then the engine is controlled to start immediately and remain in the start state. After starting, the engine maintains a mechanical power output of 5kw. The engine speed is determined by the number of effective continuous gear shifts in the D gear when the hybrid vehicle is in the launch start preparation state. When the operation time between two consecutive gear shifts is less than 1.5 seconds, the effective continuous gear shift number is two, and the engine speed after starting is maintained at 2000 rpm. When the operation time between three consecutive gear shifts is less than 1.5 seconds, the effective continuous gear shift number is three, and the engine speed after starting is maintained at 2500 rpm. If the effective continuous gear shift number is four or more, the engine speed after starting is maintained at 3000 rpm. In order to ensure that the drive motor has the fastest possible torque response, the torque response of the drive motor comes directly from the vehicle PedalMap table (i.e., the driver's required torque is obtained by looking up the throttle opening and vehicle speed), and the drivability filtering algorithm and the drive torque NVH control algorithm are controlled to stop calculating the torque of the drive motor. Through such control, the engine can be started immediately and the engine's operating speed can be increased when the hybrid vehicle is launched, thereby ensuring that the engine has a faster power output speed to ensure the power use of the drive motor, and by controlling the hybrid vehicle's Autohold function to be turned off, the EPB is automatically unlocked, which can facilitate the rapid start of the hybrid vehicle.

[0049] Optionally, Figure 4 FIG. 4 is a flow chart of a fourth embodiment of a control method for launching a hybrid vehicle according to the present application, as shown in FIG. Figure 4As shown, the control method for launching a hybrid vehicle further includes the following steps:

[0050] Step S41, when it is determined that the hybrid vehicle is not in a launch start preparation state, obtaining a first target speed and a first target torque of the engine, and obtaining a second target torque of the drive motor;

[0051] Step S42, generating a second control strategy based on the first target speed, the first target torque and the second target torque, the second control strategy includes controlling the engine to output the first target speed and the first target torque, controlling the drive motor to output the second target torque, and controlling the current state of the automatic parking system to be restored to a state when the hybrid vehicle is not in a launch start preparation state.

[0052] In this embodiment, after determining that the hybrid vehicle is not in the launch start preparation state, it proves that the hybrid vehicle has no launch start requirement. At this time, the second control strategy is executed, so that according to the actual situation of the hybrid vehicle, the target devices such as the engine, drive motor and automatic parking system of the hybrid vehicle can be controlled to execute corresponding control strategies.

[0053] Optionally, obtaining the first target speed and the first target torque of the engine and obtaining the second target torque of the drive motor include calculating the first target speed and the first target torque based on the vehicle energy management algorithm, calculating the second target torque based on the drivability filtering algorithm and the drive torque NVH control algorithm, and obtaining the first target speed, the first target torque, and the second target torque. In this embodiment, if the first target speed and the first target torque calculated by the vehicle energy management algorithm are zero, the engine is controlled to stop.

[0054] According to another specific embodiment of the present application, a control device for launching a hybrid vehicle is also provided. Figure 5As shown, the control device includes a collection module 42, a judgment module 44 and a control module 46. The collection module 42 is used to collect the working condition information of the hybrid vehicle, and the working condition information includes at least one of the following: the starting state of the hybrid vehicle, the number of effective continuous gear shifting in the D gear; the judgment module 44 determines whether the hybrid vehicle is in the launch start preparation state according to the working condition information; the control module 46 generates a first control strategy based on the number of effective continuous gear shifting in the D gear when the hybrid vehicle is in the launch start preparation state, wherein the first control strategy includes controlling the automatic parking system function of the hybrid vehicle to be turned off, controlling the electronic parking system of the brake system to be unlocked, controlling the engine to start immediately and keep the start state, and controlling the engine to keep outputting the preset power, target speed and target torque after starting, controlling the drive motor to output the driver's required torque, controlling the drivability filtering algorithm and the drive torque NVH control algorithm to stop calculating the torque of the drive motor, and controlling the water pump and fan for cooling the drive motor and the generator to rotate at full speed.
