An exception to this definition will occur only when a combination of elements, functions, steps or operations are in some way inherently mutually exclusive.
FIG. 1 is a schematic flow diagram illustrating a kinetic energy recovery method according to one embodiment. As shown in fig. 1, the kinetic energy recovery method of the present embodiment includes:
step S210, first vehicle information of the hybrid mixer truck is obtained.
The kinetic energy recovery method can be applied to a mixing truck. The mixing truck consists of a chassis, an upper part (stirring tank), a controller, a generator driver, an upper motor driver, a battery and a heat dissipation system assembly. The chassis obtains power through the engine and drives the engine through the flywheel, and the upper motor is provided with a power supply by a battery to drive the stirring cylinder to work. When the upper power supply is insufficient, the upper power generator is driven by the power generator to generate power, or the external charging device charges the power.
Kinetic energy recovery is the conversion of kinetic energy of a vehicle into electrical energy, the conversion of linear motion of the vehicle into rotational motion by a vehicle drive train, and the conversion of rotational kinetic energy into electrical energy by a generator. The formula for recovering energy is as follows:
wherein m represents the mass of the whole vehicle; v t Indicating an initial speed of the mixer truck; v 0 Indicating the end speed of the mixer truck; alpha represents a kinetic energy conversion coefficient; s represents the circumference of the tire of the mixer truck; k is a constant coefficient and has a value of 1.1-1.25; i represents a gear ratio;representing magnetic flux; i represents a charging current; t represents the braking time.
The generator is used as a kinetic energy recovery device, is connected with the engine through a transmission shaft, closes an internal circuit when the system triggers kinetic energy recovery, and is used as a load to convert kinetic energy into electric energy to directly drive the upper motor or store the electric energy into the energy storage device.
The first vehicle information comprises at least one of the speed, the brake pedal state, the gear and the engine speed of the hybrid mixer truck.
The control system actively collects information such as the speed, the brake, the gear and the engine speed of the vehicle through the controller, analyzes and judges whether the vehicle enters a kinetic energy recovery state, if the kinetic energy recovery state is triggered, the kinetic energy recovery strategy is executed, namely, the controller controls a generator driver and a generator to generate electricity, controls the torque of a motor and matches the current speed, the gear and the engine speed.
Step S220, if the first vehicle information meets the preset condition, executing a kinetic energy recovery strategy of the hybrid mixer truck so as to control the generator to convert the kinetic energy into electric energy and drive the loading motor.
Optionally, the first vehicle information satisfies a preset condition, including at least one of:
the speed of the mixing truck is greater than zero;
the mixing truck is in a braking state;
the gear of the mixing truck is not neutral;
the rotational speed of the engine is greater than the idle rotational speed.
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 depressed to trigger the braking condition, the gear of the vehicle is put into neutral gear, and the engine speed is reduced to idle speed, the hybrid mixer truck is judged to trigger the kinetic energy recovery strategy. For example, when the engine speed is 500 to 600rpm, it is determined as the idle speed. Therefore, the kinetic energy recovery is carried out under the condition of non-idle rotation speed, idle load is not caused, and idle oil consumption of the vehicle is improved.
Optionally, after executing the kinetic energy recovery strategy of the hybrid mixer truck, the method further comprises:
continuously collecting first vehicle information of the hybrid mixer truck;
and if the first vehicle information does not meet the preset condition, stopping executing the kinetic energy recovery strategy.
Fig. 2 is a schematic flow diagram showing a method of recovering kinetic energy according to an embodiment. As shown in fig. 2, information such as the speed, braking state, gear information, and engine speed of the hybrid mixer truck is first collected. Then judging whether the vehicle speed is zero or not in sequence, and stopping kinetic energy recovery if the vehicle speed is zero; if the vehicle speed is not zero, continuing to judge whether to trigger braking. If the brake is not triggered, stopping the recovery of kinetic energy; if the brake is triggered, whether the vehicle gear is engaged in the neutral gear is continuously judged. If the neutral gear is engaged, stopping the kinetic energy recovery; if the neutral gear is not engaged, the determination is continued as to whether the engine speed of the vehicle is reduced to idle. If the speed is reduced to the idle speed, stopping the recovery of kinetic energy; and if the speed is not reduced to the idle speed, continuing to execute the kinetic energy recovery strategy. And continuously judging the first vehicle information in the process of executing the kinetic energy recovery strategy. That is, first vehicle information of the hybrid vehicle, such as vehicle speed, brake pedal state, vehicle gear information, engine speed, etc., is continuously collected. And if the first vehicle information does not meet the preset condition, stopping executing the kinetic energy recovery strategy. Therefore, on the premise of not adding additional devices, the existing generator of the hybrid mixer truck is used as a kinetic energy recovery device, so that the kinetic energy recovery of the hybrid mixer truck is realized.
Step S230, obtaining second vehicle information of the hybrid mixer truck.
Wherein the second vehicle information includes at least one of a vehicle load amount, a vehicle acceleration, and a brake pedal opening.
Here, in the course of executing the kinetic energy recovery strategy, second vehicle information such as the vehicle load amount, acceleration, and brake pedal opening is acquired. Wherein the load mass may be a top-loading concrete mass.
And step S240, adjusting a kinetic energy recovery strategy according to the second vehicle information to enable the hybrid mixer truck to brake stably.
Optionally, adjusting the kinetic energy recovery strategy according to the second vehicle information includes:
the torque value of the generator is adjusted.
When the vehicle runs, the brake is pressed down and the neutral gear is not engaged, the engine is connected with the wheels through the gear train, the rotation speed of the wheels is in a fixed ratio with the rotation speed of the engine on the premise of not shifting gears, the motor is connected with the engine through the transmission shaft, and the internal circuit is closed, so that the generator becomes a load. At the moment, the engine does not work any more, the kinetic energy of the vehicle drives the wheels to rotate, the gear train drives the generator to rotate, the rotation speed of the engine is reduced, the rotation speed of the wheels is reduced, the kinetic energy of the vehicle is converted into the generated electric energy, and the kinetic energy recovery is realized. In the process of recovering kinetic energy, the torque of the generator needs to be controlled, so that the stable deceleration of the vehicle is realized. The set torque M of the generator is:
M＝k 1 ×m×a×R
wherein the total mass of the vehicle is m, the acceleration is a, and the transmission coefficient is k 1 The tire radius is R.
Optionally, adjusting the torque value of the generator includes:
if the vehicle load mass is smaller than or equal to the preset mass, setting the torque value of the generator to be a fixed value;
if the vehicle load mass is larger than the preset mass, setting the vehicle acceleration as a fixed value, and dynamically adjusting the torque value of the generator.
As shown in fig. 3, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation is started until the kinetic energy recovery strategy is finished. When the vehicle load mass is less than or equal to the preset mass, the torque of the generator may be set to a fixed value. At this time, the kinetic energy recovery strategy varies with the mass of the load and the deceleration of the vehicle. The smaller the load mass is, the more obvious the deceleration effect is, which is beneficial to the smooth deceleration of the vehicle.
As shown in fig. 4, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation is started. In the power generation process, the power generation torque M is adjusted in real time according to the change of the acceleration of the vehicle. When the vehicle load mass is greater than the preset mass, the acceleration can be set to be a fixed value, and the torque of the generator is a dynamic value. And controlling the torque of the generator along with the feedback of the actual vehicle speed. In this way, the acceleration remains constant regardless of the load. In this way, a smooth deceleration during kinetic energy recovery can be ensured.
Optionally, adjusting the torque value of the generator further comprises:
and adjusting the torque value of the generator according to the opening degree of a brake pedal of the hybrid mixer truck.
As shown in fig. 5, after the kinetic energy recovery strategy is triggered, the power generation torque value M is set, and then power generation is started. In the power generation process, the power generation torque M is adjusted in real time according to the opening change of the brake pedal. It will be appreciated that the generator torque is tied to the brake pedal opening, through which the generator torque is regulated. If the vehicle is required to be stopped quickly, the opening degree of the brake pedal is larger, and the torque of the generator is increased at the moment, so that the energy recovery power is increased. And simultaneously, the speed of the vehicle can be reduced. Similarly, when rapid stopping is not needed, the opening degree of the collected brake pedal is smaller, and the engine torque is reduced. The kinetic energy recovery power is reduced, and the change of the vehicle speed is also slowed down.
The kinetic energy recovery method of the embodiment of the application is applied to a mixing truck, and the mixing truck comprises an engine, a generator and an upper motor, and comprises the following steps: acquiring first vehicle information of a hybrid mixer truck; if the first vehicle information meets the preset condition, executing a kinetic energy recovery strategy of the hybrid mixer truck so as to control the generator to convert kinetic energy into electric energy and drive the upper motor; acquiring second vehicle information of the hybrid mixer truck; and adjusting the kinetic energy recovery strategy according to the second vehicle information. The utility model discloses a utilize the generator of mixing the stirring truck to realize kinetic energy recovery and drive the upper assembling, based on the real-time state dynamic adjustment kinetic energy recovery tactics of vehicle, be favorable to realizing the steady speed reduction of vehicle when kinetic energy is retrieved to mixing the stirring truck.
