[0043] Figure 1 FIG. 1 is a flow chart of a kinetic energy recovery method according to an embodiment. Figure 1 As shown, the kinetic energy recovery method of this embodiment includes:

[0044] Step S210, obtaining first vehicle information of the hybrid mixer truck.

[0045] The kinetic energy recovery method of the present application can be applied to a hybrid mixer truck. The hybrid mixer truck is composed of a chassis, a superstructure (mixing tank), a controller, a generator, a generator driver, a superstructure motor, a superstructure motor driver, a battery, and a cooling system assembly. The chassis obtains power from the engine and drives the engine through the flywheel. The superstructure motor is powered by a battery to drive the mixing drum. When the superstructure power supply is insufficient, the superstructure generator is driven by the generator to generate electricity, or it is charged by an external charging device.

[0046] Kinetic energy recovery is the process of converting the vehicle's kinetic energy into electrical energy. The vehicle's linear motion is converted into rotational motion through the vehicle's transmission system, and the rotational kinetic energy is converted into electrical energy through the generator. The formula for recovering energy is as follows:

[0047]

[0048] In the formula, m represents the vehicle mass; v t represents the initial speed of the mixer truck; v 0represents the final speed of the mixer truck; α represents the kinetic energy conversion coefficient; S represents the tire circumference of the mixer truck; K is a constant coefficient, ranging from 1.1 to 1.25; i represents the transmission ratio; represents magnetic flux; I represents charging current; t represents braking time.

[0049] The generator serves as a kinetic energy recovery device, which is connected to the engine through a drive shaft. When the system triggers kinetic energy recovery, the internal circuit is closed. The generator, as a load, converts kinetic energy into electrical energy, directly driving the upper motor or storing it in an energy storage device.

[0050] The first vehicle information includes at least one of the vehicle speed, brake pedal status, gear position, and engine speed of the hybrid mixer truck.

[0051] Here, the control system actively collects information such as the vehicle's speed, brakes, gear and engine speed through the controller, analyzes and determines whether to enter the kinetic energy recovery state. If the kinetic energy recovery state is triggered, the kinetic energy recovery strategy is executed, that is, the controller controls the generator driver and generator to generate electricity, and controls the motor torque to match the current vehicle speed, gear and engine speed.

[0052] Step S220: If the first vehicle information meets the preset conditions, the kinetic energy recovery strategy of the hybrid mixer truck is executed to control the generator to convert the kinetic energy into electrical energy to drive the upper motor.

[0053] Optionally, the first vehicle information satisfies a preset condition, including at least one of the following:

[0054] The speed of the hybrid mixer truck is greater than zero;

[0055] The hybrid mixer truck is in braking state;

[0056] The gear position of the hybrid mixer truck is not neutral;

[0057] The engine speed is greater than the idle speed.

[0058] Preferably, when the first vehicle information simultaneously satisfies the conditions that the speed of the hybrid mixer truck is not zero, the brake pedal is pressed to trigger the braking condition, the vehicle gear is in neutral, and the engine speed drops to idle, it is determined that the hybrid mixer truck triggers the kinetic energy recovery strategy. Exemplarily, when the engine speed is 500-600rpm, it is determined to be the idle speed. In this way, kinetic energy recovery is performed under non-idle speed conditions, which does not cause idle load and improves the vehicle's idle fuel consumption.

[0059] Optionally, after executing the kinetic energy recovery strategy of the hybrid mixer truck, the method further includes:

[0060] Continuously collect the first vehicle information of the hybrid mixer truck;

[0061] If the first vehicle information does not meet the preset condition, the kinetic energy recovery strategy is stopped.

[0062] Figure 2 FIG. 1 is a schematic diagram of a specific process of a kinetic energy recovery method according to an embodiment. Figure 2 As shown, first collect information such as the vehicle speed, brake status, gear information, and engine speed of the hybrid mixer truck. Then determine whether the vehicle speed is zero in turn. If the vehicle speed is zero, stop kinetic energy recovery; if the vehicle speed is not zero, continue to determine whether the brake is triggered. If the brake is not triggered, stop kinetic energy recovery; if the brake is triggered, continue to determine whether the vehicle gear is in neutral. If it is in neutral, stop kinetic energy recovery; if it is not in neutral, continue to determine whether the vehicle's engine speed drops to idle. If it drops to idle, stop kinetic energy recovery; if it does not drop to idle, continue to execute the kinetic energy recovery strategy. And in the process of executing the kinetic energy recovery strategy, continue to judge the first vehicle information. In other words, continue to collect the first vehicle information of the hybrid mixer truck, such as vehicle speed, brake pedal status, vehicle gear information, engine speed, etc. If the first vehicle information does not meet the preset conditions, stop executing the kinetic energy recovery strategy. In this way, without adding additional devices, the generator of the existing hybrid mixer truck is used as a kinetic energy recovery device to achieve kinetic energy recovery of the hybrid mixer truck.

[0063] Step S230, obtaining second vehicle information of the hybrid mixer truck.

[0064] The second vehicle information includes at least one of vehicle loading mass, vehicle acceleration and brake pedal opening.

[0065] Here, in the process of executing the kinetic energy recovery strategy, the second vehicle information such as the vehicle load mass, acceleration and brake pedal opening is obtained, wherein the load mass may be the mass of the concrete loaded on the vehicle.

[0066] Step S240: adjusting the kinetic energy recovery strategy according to the second vehicle information to enable the hybrid mixer truck to brake smoothly.

[0067] Optionally, adjusting the kinetic energy recovery strategy according to the second vehicle information includes:

[0068] Adjust the torque value of the generator.

[0069] When the vehicle is driving, the brakes are pressed and the gear is not in neutral. The engine and wheels are connected through a gear system. Without shifting gears, the wheel speed is proportional to the engine speed. The motor and engine are connected through a drive shaft, closing the internal circuit and making the generator a load. At this time, the engine no longer works, and the kinetic energy of the vehicle drives the wheels to rotate, which in turn drives the generator through the gear system. At this time, the engine speed will decrease, and the wheel speed will also decrease. The kinetic energy of the vehicle is converted into electrical energy for power generation, realizing kinetic energy recovery. In the process of kinetic energy recovery, the generator torque needs to be controlled to achieve smooth deceleration of the vehicle. The set torque M of the generator is:

[0070] M=k 1 ×m×a×R

[0071] In the formula, the total mass of the vehicle is m, the acceleration is a, and the transmission coefficient is k 1 , the tire radius is R.

[0072] Optionally, adjusting the torque value of the generator includes:

[0073] If the mass of the vehicle load is less than or equal to the preset mass, the torque value of the generator is set to a fixed value;

[0074] If the mass of the vehicle's load is greater than the preset mass, the vehicle acceleration is set to a fixed value and the torque value of the generator is dynamically adjusted.

[0075] like Figure 3 As shown, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation starts until the kinetic energy recovery strategy ends. When the vehicle load mass is less than or equal to the preset mass, the torque of the generator can be set to a fixed value. At this time, the kinetic energy recovery strategy has different deceleration effects on the vehicle depending on the mass of the load. The smaller the load mass, the more obvious the deceleration effect, which is conducive to the smooth deceleration of the vehicle.

[0076] like Figure 4 As shown in the figure, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation begins. During the power generation process, the power generation torque M is adjusted in real time according to the change of vehicle acceleration. When the mass of the vehicle load is greater than the preset mass, the acceleration can be set to a fixed value, and the torque of the generator is a dynamic value. With the feedback of the actual vehicle speed, the size of the generator torque is controlled. In this way, regardless of the amount of load, the acceleration remains constant. In this way, smooth deceleration during the kinetic energy recovery process can be ensured.

[0077] Optionally, adjusting the torque value of the generator further includes:

[0078] The torque value of the generator is adjusted according to the brake pedal opening of the hybrid mixer truck.

[0079] like Figure 5As shown, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation begins. During the power generation process, the power generation torque M is adjusted in real time according to the change in the opening of the brake pedal. It can be understood that the generator torque is bound to the brake pedal opening, and the generator torque is adjusted by the brake pedal opening. If you need to stop quickly, the opening of the brake pedal will be larger, at which time the generator torque increases, increasing the power of energy recovery. At the same time, it will also slow down the vehicle speed. Similarly, when there is no need to stop quickly, the opening of the brake pedal will be smaller, and the engine torque will also decrease. The kinetic energy recovery power decreases, and the vehicle speed change will also slow down.

[0080] The kinetic energy recovery method of the embodiment of the present application is applied to a hybrid mixer truck, which includes an engine, a generator, and an upper motor, and includes: obtaining first vehicle information of the hybrid mixer truck; if the first vehicle information meets a preset condition, executing the kinetic energy recovery strategy of the hybrid mixer truck to control the generator to convert kinetic energy into electrical energy to drive the upper motor; obtaining second vehicle information of the hybrid mixer truck; adjusting the kinetic energy recovery strategy according to the second vehicle information. The present application utilizes the generator of the hybrid mixer truck to achieve kinetic energy recovery and drive the upper motor, and dynamically adjusts the kinetic energy recovery strategy based on the real-time status of the vehicle, which is beneficial to achieving smooth deceleration of the hybrid mixer truck while recovering kinetic energy.
