Background

During the running process of the vehicle, a driver generally steps on an accelerator to accelerate the running and steps on a brake to decelerate the running.

The scheme of the application can be applied to the field of automobiles, and is particularly applied to the ejection starting process of vehicles such as hybrid electric vehicles or pure electric vehicles in series-parallel configuration. The wheel end power output mechanism is a driving motor when the vehicle runs at low speed. Launch refers to a driver depressing the power pedal and the brake pedal simultaneously so that the engine of the vehicle outputs a large amount of power but the vehicle is still stopped. The driver releases the brake pedal, so that the vehicle can obtain larger advancing power instantly, and the vehicle can be started quickly. According to the scheme, in the scene, a driver does not need to change the original launch starting operation process, the driver only needs to carry out the starting process according to the pedal activation process of the conventional launch starting without carrying out additional operation, the vehicle can activate the corresponding launch starting process, the output power is properly limited in the starting process, and the situation that the unexpected action is caused or the unexpected purpose cannot be achieved due to too low power of the vehicle is avoided.

Fig. 1 schematically shows an exemplary system architecture diagram of the present technical solution in an application scenario. As shown in fig. 1, the vehicle includes a shift lever, a power pedal, and a brake pedal, and corresponding sensors are connected to the shift lever, the power pedal, and the brake pedal, respectively, to detect information such as the position of the shift lever and the opening degree of the pedal. The information is transmitted to the controller, the controller performs calculation according to the received information, and sends a control instruction to the power module based on the calculation result, so that the adjustment process of the vehicle power is realized. It will be appreciated that the power pedal is used to control the power output of the vehicle, which may play a different role in different types of vehicles, such as controlling the amount of oil in a fuel vehicle, controlling the power of an electric motor in an electric vehicle, etc., and may be named differently, such as an accelerator pedal or an electric door pedal, etc.

The technical solutions provided in the present application are described in detail below with reference to specific embodiments. Referring to fig. 2, fig. 2 is a schematic flow chart of a vehicle power control method according to an embodiment of the present application. It is understood that the subject of execution of the method may be a unit for vehicle control, such as an onboard controller or control module or a remote computing unit. Taking the vehicle-mounted controller as an example, the vehicle power control method of the present application includes the following steps S210 to S230:

and step S210, controlling the vehicle to enter a double-pedal control state according to the position of a gear shifting lever of the vehicle, the power opening degree of a power pedal and the braking opening degree of a brake pedal.

Specifically, in this embodiment, the onboard controller controls the state of the vehicle based on the position of the shift lever of the vehicle, the power opening of the power pedal, and the brake opening of the brake pedal. The normal use of the vehicle is in a single pedal control state, i.e., a control state in which only one of the power pedal and the brake pedal is depressed or activated at the same time. And when the power opening degree of the power pedal and the braking opening degree of the braking pedal reach certain threshold degree, the controller can judge that the two pedals are simultaneously stepped on, and at the moment, the vehicle can enter a double-pedal control state. In this state, the on-board controller adjusts or limits the power opening of the power pedal according to a preset threshold value, thereby adjusting and limiting the power of the vehicle. When the vehicle is powered on, the default is a single-pedal control state, in the running process, after the conditions that the position of a gear shift lever, the power opening of a power pedal and the brake opening of a brake pedal meet the conditions of entering a double-pedal control mode are detected, the state of a double-pedal is entered, and the vehicle is controlled to run according to the control method of the double-pedal of the vehicle.

Step S220, detecting an activation order of the power pedal and the brake pedal when the vehicle is in the dual-pedal control state.

In this embodiment, the sequence of activation of the power pedal and the brake pedal is detected while the vehicle is in the two-pedal control state. The activation sequence is typically the sequence in which the power pedal and brake pedal are depressed upon entering the two-pedal control state.

And step S230, determining an opening threshold value according to the vehicle speed of the vehicle and the activation sequence, and adjusting the power opening according to the opening threshold value so as to control the power output by the vehicle.

In this embodiment, in the two-pedal control state, the on-board controller determines corresponding opening threshold values according to the vehicle speed and different activation sequences of the power pedal and the brake pedal, and adjusts the power opening of the power pedal using the determined opening threshold values, thereby controlling the power output by the engine of the vehicle. Specifically, a control system of the vehicle may store a plurality of preset opening degree threshold values in advance. The on-board controller determines an opening threshold value suitable for the current state according to the vehicle speed and the stepping sequence of the pedals, and adjusts the power opening according to the determined opening threshold value. In one embodiment, the vehicle-mounted controller may further calculate a suitable opening threshold value according to a preset formula or condition according to the power opening, the brake opening and the current vehicle speed.

In the embodiment of the application, a double-pedal control state is entered according to the conditions of the position of a gear shifting lever, a power pedal and a brake pedal, and then a corresponding opening threshold value is determined according to the vehicle speed and the activated sequence of the two pedals to control the power opening, so that the power output by the double-pedal function does not exceed the power output by the preset opening, therefore, under the condition that the user does not need to accurately control the power opening and perform complex operation to activate the double-pedal control function, the usability of the vehicle function is improved, meanwhile, the unexpected action caused by overhigh power of the vehicle is avoided, and the safety of the vehicle is improved.

In an embodiment of the application, based on the above technical solution, in the step S230, determining an opening threshold according to the vehicle speed of the vehicle and the activation sequence, and adjusting the power opening according to the opening threshold, so as to control the power output by the vehicle, specifically, the method includes the following steps:

In this embodiment, during the first calculation cycle of entering the two-pedal control state, the onboard controller will respectively confirm three different power control strategies and corresponding opening degree thresholds according to the vehicle speed and different activation sequences. Specifically, the three opening degree thresholds correspond to three different power opening degree control strategies, including a strategy of controlling the power opening degree at a large value, a strategy of controlling the power opening degree at a small value, and a zero power opening degree strategy. If the vehicle speed is less than the vehicle speed threshold value and the activation sequence is that the brake pedal is activated before the power pedal, the vehicle-mounted controller adopts a strategy of controlling the power opening degree at a larger value and controls the power opening degree according to the first opening degree threshold value. The strategy shows that a driver expects a launch starting mode, the first opening threshold value is usually set to be high, so that the power output by the whole vehicle can enable the vehicle to have strong launch starting capability under the power opening, the temperature of a driving motor and the temperature of a motor controller during launch starting are ensured not to exceed the normal design temperature, for example, the vehicle speed threshold value is 5km/h, and the first opening threshold value is 50% of the maximum opening. The power opening degree of the vehicle may be raised or directly set to the first opening degree threshold value, thereby raising the power output from the engine.

If the vehicle speed is greater than the vehicle speed threshold and the activation sequence is that the power pedal is activated before the brake pedal, the onboard controller employs a zero power opening strategy and controls the power opening according to a second opening threshold, wherein the second opening threshold is less than the first opening threshold. This strategy indicates that the vehicle has been running at a certain speed and the sequence of first stepping on the accelerator and then stepping on the brake also indicates that the driver has an intention to brake, and therefore the second opening threshold value usually takes a value of 0 or close to 0 so that the power output from the engine is reduced to rapidly reduce the vehicle speed. It is understood that in this strategy, when the power pedal is depressed, but the power opening degree is zero, only the brake opening degree of the brake pedal is applied, and the vehicle is braked.

If the vehicle speed and the activation sequence do not satisfy the condition of controlling the power opening degree according to the first opening degree threshold value or according to the second opening degree threshold value, the vehicle-mounted controller adopts a strategy of controlling the power opening degree at a smaller value, and controls the power opening degree according to a third opening degree threshold value, wherein the third opening degree threshold value is larger than the second opening degree threshold value and smaller than the first opening degree threshold value. In this strategy, the third opening degree threshold is a smaller value, for example, the third opening degree threshold is 20% of the maximum opening degree. The third opening threshold value ensures that the whole vehicle has certain power output under the power opening, and ensures that the temperature of the driving motor and the temperature of the motor controller do not exceed the normal design temperature under the condition that the driving motor is blocked for a long time. If the catapult starting time of a driver is too long, the driver can turn to the strategy to prevent the motor from blocking for a long time and prevent the temperature of a motor controller or the temperature of the motor from being too high.

In the scheme of this application, come to carry out different control to power aperture through different conditions to can all step on the multiple scene of driving pedal and brake pedal, can accurately discern driver's intention, the whole car power that the output driver looked for.

In an embodiment of the application, based on the above technical solution, the step of controlling the power opening according to a first opening threshold specifically includes the following steps:

Specifically, in the embodiment of the present application, in the strategy of controlling the power opening degree at a larger value, if the current power opening degree is larger than a set first power opening degree threshold value, the power opening degree is limited to the first power opening degree threshold value; and if the current power opening degree is smaller than or equal to the first power opening degree threshold value, the power opening degree is the current power opening degree.

Similarly, in the strategy of controlling the power opening at a smaller value, if the current power opening is greater than the set second power opening threshold, preferably 20%, the power opening is limited to the set second power opening threshold; and if the current power opening is smaller than or equal to the second power opening threshold, the power opening is the current power opening.

In the zero power opening degree strategy, when the vehicle speed exceeds a vehicle speed threshold value, the vehicle control executes a brake priority principle, and when a driver steps on the brake, the vehicle does not output power, and the power opening degree is controlled to be zero.

In an embodiment of the application, based on the above technical solution, if the vehicle speed and the activation order do not satisfy a condition for controlling the power opening degree according to the first opening degree threshold or the second opening degree threshold, the step of controlling the power opening degree according to a third opening degree threshold includes:

if the power pedal and the brake pedal are both activated and the shift lever position is switched from a neutral or park position to a forward or reverse gear, or if the shift lever position is not in the neutral or park position, the vehicle speed is less than or equal to the vehicle speed threshold and the power pedal is activated before the brake pedal, or if the shift lever position is not in the neutral or park position, the vehicle speed is greater than the vehicle speed threshold and the brake pedal is activated before the power pedal, reducing the power opening to the fourth opening threshold with a preset slope.

Specifically, the strategy for controlling the power opening degree to a smaller value is provided with three parallel groups of conditions, and the strategy is entered when the vehicle meets any one group of conditions. Specifically, the conditions include: the vehicle may enter a strategy to control the power opening to a lesser value (1) if both the power pedal and the brake pedal are activated and the shift lever position is switched from a neutral or park position to a forward or reverse gear, or (2) if the shift lever position is not in a neutral or park position, the vehicle speed is less than or equal to a vehicle speed threshold and the power pedal is activated before the brake pedal, or (3) if the shift lever position is not in a neutral or park position, the vehicle speed is greater than a vehicle speed threshold and the brake pedal is activated before the power pedal. At this time, the vehicle is directly switched from the single-pedal control state to the strategy of controlling the power opening at a smaller value, so that the power opening is reduced to the fourth opening with a preset slope. In a specific example, the above conditions may be, for example: the method comprises the following steps of (1) enabling a gear shift lever to be in a P/N gear, enabling a brake pedal and a power pedal to be both stepped on, and switching the gear shift lever from the P/N gear to the D/R gear, or (2) enabling the gear shift lever to be in a non-P/N gear, enabling the vehicle speed to be smaller than or equal to a set vehicle speed threshold value, and firstly stepping on the power pedal and then stepping on the brake pedal, or (3) enabling the gear shift lever to be in a non-P/N gear, enabling the vehicle speed to be larger than the set vehicle speed threshold value, and firstly stepping on the brake pedal and then stepping on the power pedal.

In an embodiment of the application, based on the above technical solution, after the controlling the power opening according to the first opening threshold, the method further includes:

In the present embodiment, after entering the strategy of controlling the power opening degree at a larger value, the vehicle controller detects the current state of the vehicle, and exits the strategy of controlling the power opening degree at a larger value if the current state satisfies a certain condition. Specifically, the strategy for exiting the control of the power opening degree at a large value includes three conditions, which are respectively: if (1) the time for controlling the power opening degree according to the first opening degree threshold value reaches a preset time threshold value, or (2) if the vehicle speed is greater than the vehicle speed threshold value, or (3) if the position of the gear shifting lever changes, the vehicle enters a strategy for controlling the power opening degree to be a smaller value, and the power opening degree is reduced to a second opening degree threshold value according to a preset slope. In a specific example, the above conditions may be, for example: and if the time of the power opening degree control in the large value strategy exceeds 5 seconds, or if the vehicle speed exceeds the vehicle speed threshold value, or if the position of the shift lever is changed, such as the shift lever is switched from the D gear to the R gear, the shift lever is switched from the R gear to the D gear. At the moment, the vehicle jumps from the strategy of controlling the power opening at a larger value to the strategy of controlling the power opening at a smaller value, and if the power opening is larger than the second accelerator opening threshold value, the power opening is reduced to the second accelerator opening threshold value according to a certain slope.

In an embodiment of the application, based on the above technical solution, the step S210 of controlling the vehicle to enter the dual-pedal control state according to the shift lever position of the vehicle, the power opening of the power pedal, and the brake opening of the brake pedal includes the following steps:

Specifically, in the present embodiment, the on-board controller controls the vehicle to enter the two-pedal control state if the shift lever position is not in the neutral or parking position, the power opening is greater than or equal to the fourth power opening threshold, and the brake opening is greater than or equal to the brake opening threshold. For example, if the vehicle-mounted controller detects that the shift lever position is not in the P/N gear, the current power opening is greater than or equal to the fourth power opening threshold, for example, 5%, and the brake pedal opening is greater than or equal to the set brake pedal opening threshold, for example, 3%, then the dual-pedal state is entered. It is understood that in the case of the single-pedal control state and the above-described conditions are satisfied, the shift position of the vehicle is forward or reverse, and both the power pedal and the brake pedal are depressed to some extent, so that it can be determined that the driver wants to use a function in the two-pedal control state, such as launch start, or that the driver has depressed both pedals simultaneously due to a driving error, and the next control determination needs to be made by the vehicle in the two-pedal control state.

In an embodiment of the application, based on the above technical solution, in step S230, after the power opening is adjusted by using a preset opening threshold according to the vehicle speed of the vehicle and the activation sequence, the method further includes:

and when the situation that the position of the gear shifting rod is switched to the parking position is detected, or if the power opening degree is smaller than the fourth power opening degree threshold value or if the brake opening degree is smaller than the brake opening degree threshold value, controlling the vehicle to enter a single-pedal control state.

Specifically, in this embodiment, the on-board controller switches to the single-pedal control state after a certain condition is satisfied by the vehicle. Specifically, if the on-board controller detects that the shift lever position is switched to the parking position, or if the power opening is less than the fourth power opening threshold or if the brake opening is less than the brake opening threshold, indicating that the vehicle has finished starting or aborted launch, the vehicle is controlled to enter the single-pedal control state. For example, if the vehicle-mounted controller detects that the gear shift lever is in the P-gear or the current power opening is smaller than the fourth power opening threshold or the brake pedal opening is smaller than the brake pedal opening threshold, the single-pedal control state is entered.

The general scheme of the present application will be described below with reference to specific examples. For convenience of introduction, please refer to fig. 3, and fig. 3 is a schematic flowchart illustrating a control state switching process according to an embodiment of the present application. As shown in fig. 3, after the vehicle is started, the single pedal control state is first entered in step 310, and then the position of the shift lever and the conditions of the accelerator pedal and the brake pedal are checked. If the shift lever is not in the P/N range and the accelerator pedal and brake pedal are both depressed in step 320, the shift is to the two-pedal control state in step 330 and the position of the shift lever and the condition of the accelerator pedal and brake pedal continue to be sensed. In the two-pedal control state, if the shift lever is detected as P-range or accelerator pedal release or brake pedal release in step 340, the single-pedal control state in step 310 is returned.

In the two-pedal control state, the vehicle switches between three accelerator opening degree control modes. Specifically, referring to fig. 4, fig. 4 is an exemplary flowchart of switching the accelerator opening degree control mode in the embodiment of the present application. After entering the two-pedal control state, as shown in fig. 4, the shift lever, vehicle speed, brake pedal, and accelerator pedal are checked in step 410. If the gear shift lever is in a non-P/N gear, the vehicle speed is less than or equal to the set vehicle speed threshold value, and the brake pedal is firstly stepped on and the accelerator pedal is then stepped on, the mode that the accelerator opening is controlled to be a larger value, namely the launch starting mode, is entered in step 420. Then in step 430, if the accelerator opening control exceeds a certain value in the larger value mode or the vehicle speed is greater than a set vehicle speed threshold or shift lever position change, then in step 440, the accelerator opening control is entered into the zero mode. If the condition in step 410 is not satisfied, the method proceeds to step 450, and if the shift lever is in non-P/N gear, the vehicle speed is greater than the set vehicle speed threshold, the accelerator is pressed first and then the brake is pressed, and the method proceeds to step 440 directly, where the accelerator opening is controlled to be in a zero mode. If neither of the conditions of step 410 and step 450 are met, then the throttle opening control is in a smaller value mode in step 460.

When jumping between a single-pedal control state and a double-pedal control state and switching between accelerator opening control modes, the vehicle-mounted controller filters the accelerator opening to obtain the accelerator opening referenced by the calculated power output, so that the smooth power output of the vehicle is ensured and the abrupt power output is prevented when the mode switching of the driving intention changing mode is carried out, and the safety of the vehicle is ensured.

Under the state of double-pedal control, when the accelerator opening is controlled to jump to the accelerator opening in a smaller mode in a larger mode, if the accelerator opening is larger than a corresponding accelerator opening threshold value, the accelerator opening is reduced to the accelerator opening threshold value according to a certain slope.

When the control of the accelerator opening degree is in a large value mode when the control is jumped from the single-pedal control state to the double-pedal control state, if the accelerator opening degree is larger than a corresponding accelerator opening degree threshold value, the accelerator opening degree is directly limited to the accelerator opening degree threshold value, the situation that the accelerator opening degree is reduced too slowly, the stalling torque of a driving motor is too large during the launch starting period, and the temperature of the driving motor or a motor controller exceeds a normal design temperature value is prevented.

Jumping to a mode of controlling the accelerator opening at a smaller value under a double-pedal control state from a single-pedal control state, and if the accelerator opening is larger than a set threshold value of the accelerator opening, reducing the accelerator opening to the set threshold value of the accelerator opening according to a certain slope; and jumping from the single-pedal control state to the accelerator opening control in the double-pedal control state to be in a zero mode, and if the accelerator opening is larger than zero, reducing the accelerator opening to zero according to a certain slope. The limitation to the descending slope of the opening degree of the accelerator reduces the whole vehicle shake caused by the over-fast descending of the opening degree of the accelerator, and improves the smoothness of the vehicle.

When the control of the accelerator opening under the double-pedal control state is jumped to the single-pedal control state in a large-value mode, the rising slope of the accelerator opening is not limited, and the accelerator opening is directly the original accelerator opening. When the vehicle exits from the launch starting, the torque of the whole vehicle is rapidly output, and the acceleration capability of the launch starting is improved.

When the control of the accelerator opening under the double-pedal control state is jumped to the single-pedal control state in a small-value mode, if the original accelerator opening is larger than a corresponding accelerator opening threshold value, the accelerator opening is increased according to a set accelerator opening rising slope; when the control of the accelerator opening under the double-pedal control state jumps to the single-pedal control state from the zero mode, if the original accelerator opening is larger than zero, the set accelerator opening increases according to the rising slope of the accelerator opening. The selection of the accelerator opening rising slope ensures the normal output of the vehicle power, the selection of the accelerator opening rising slope ensures the slow output of the vehicle power, and the vehicle power is different from the accelerator opening rising slope.
