Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle braking control method, device, vehicle and storage medium. Background Art
[0002] With the development of new energy vehicle technology, the application of wire-controlled (decoupled) braking systems in new energy vehicles is becoming more and more extensive. In new energy vehicles, coordinated regenerative braking systems are one of the key technologies to improve energy recovery efficiency and reduce energy consumption.
[0003] The matching of coordinated regenerative braking of new energy vehicles equipped with a wire-controlled (decoupled) braking system usually requires joint adjustment of wire-controlled brake control and motor control to improve the braking coordination of the coordinated regenerative braking system.
[0004] However, in actual development, due to factors such as tight project development cycles and constant adjustments to the vehicle controller software, the coordinated regenerative braking system is prone to problems such as not being able to coordinate and control hydraulic braking and motor braking well. For example, in actual applications, the torque (theoretical value) generated by the motor brake (regenerative braking) meets the braking torque requirements of the vehicle. At this time, the hydraulic brake should theoretically stop working, and the vehicle braking torque relies entirely on the motor brake. However, if the motor brake responds very slowly to the target value, the vehicle will show no braking feel or a sudden change in the vehicle deceleration, which will cause users to have poor braking smoothness and lack of braking confidence, which needs to be solved urgently. Summary of the invention

[0038] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0039] The following describes the vehicle braking control method, device, vehicle and storage medium according to embodiments of the present application with reference to the accompanying drawings.
[0040] Before introducing the vehicle braking control method of the embodiment of the present application, the braking control principle of the vehicle involved in the vehicle braking control method of the present application is briefly introduced.
[0041] Specifically, the braking control principle of the vehicle of the present application is as follows: Figure 1As shown, the master cylinder push rod stroke and the wire control brake ECU together constitute the wire control brake control unit. When the user performs normal braking, the brake information is transmitted to the wire control brake ECU (Electronic Control Unit) through the brake switch and the master cylinder push rod stroke. After the wire control brake ECU analyzes the data fed back by the user, the entire wire control brake control unit calculates the braking torque required for the whole vehicle. The wire control brake control unit receives the motor braking capacity value and the actual torque value of the motor braking issued by the vehicle controller through the CAN (Controller Area Network) transceiver, and compares the motor braking capacity value and the actual torque issued by the motor braking with the braking torque required for the whole vehicle, and adjusts the current actual total braking torque (the sum of the motor braking torque and the hydraulic braking torque) by adjusting the brake pressure to meet the braking target requirements of the whole vehicle and improve the braking smoothness.
[0042] Therefore, the wire control brake control unit monitors the actual torque generated by the motor braking in real time, compares it with the braking torque required by the entire vehicle, and controls the timing and amount of intervention of the hydraulic braking system, thereby providing the driver with a good braking feel and sufficient braking confidence.
[0043] The vehicle braking control method proposed in this application is introduced below.
[0044] Specifically, Figure 2 A schematic flow chart of a vehicle braking control method provided in an embodiment of the present application.
[0045] like Figure 2 As shown, the vehicle braking control method includes the following steps:
[0046] In step S201, the braking information of the current vehicle is obtained, and the target required braking torque is calculated according to the braking information.
[0047] In some embodiments, the braking information includes at least one of the brake pedal opening, braking duration, vehicle speed at the braking moment, and the current vehicle mass.
[0048] Specifically, the embodiment of the present application can obtain the brake pedal opening through the vehicle's opening sensor, obtain the braking duration through a timer, or obtain the braking information of the current vehicle through other methods in the prior art when the user brakes, and transmit the braking information to the wire control brake ECU through the brake switch and the brake master cylinder push rod stroke. The wire control brake ECU analyzes the received braking information and calculates the target required braking torque through the wire control brake control unit.
[0049] In step S202, the actual braking torque of the motor is obtained, and it is determined whether the actual braking torque of the motor meets the target required braking torque.
[0050] Specifically, the embodiment of the present application can collect the actual braking torque signal of the motor, that is, the actual torque generated by the motor, in real time through the wire control brake control unit, which is not specifically limited here.
[0051] In step S203, if the actual braking torque of the motor does not meet the target required braking torque, the difference between the target required braking torque and the actual braking torque of the motor is calculated to obtain the target hydraulic braking torque, and the current vehicle is braked based on the actual braking torque of the motor and the target hydraulic braking torque.
[0052] Specifically, under the premise that the motor braking capacity value can meet the target braking torque requirement, if the torque actually generated by the motor braking cannot meet the target braking torque, the wire control brake ECU is used to analyze and calculate the user's demand for braking torque, and calculate the difference between the target braking torque and the actual braking torque of the motor to obtain the target hydraulic braking torque, and send a command to the hydraulic braking system, which makes up for the insufficient braking torque based on the target hydraulic braking torque, and controls the braking of the current vehicle based on the actual braking torque of the motor and the target hydraulic braking torque to meet the target braking torque of the whole vehicle and improve braking smoothness.
[0053] Further, in some embodiments, braking control is performed on the current vehicle based on the actual braking torque of the motor and the target hydraulic braking torque, including: controlling the motor braking system of the current vehicle to perform braking control based on the actual braking torque, and controlling the hydraulic braking system to perform braking control based on the target hydraulic braking torque.
[0054] Specifically, when the actual torque generated by the motor brake cannot meet the target braking torque, the motor braking system of the current vehicle is controlled to continue to perform braking control based on the actual braking torque, and the hydraulic braking system is controlled to intervene to provide additional target hydraulic braking torque to supplement the braking torque and avoid impact and unevenness during braking.
[0055] Furthermore, in some embodiments, after determining whether the actual braking torque of the motor meets the target required braking torque, it also includes: if the actual braking torque of the motor meets the target required braking torque, controlling the motor braking system to perform braking control based on the actual braking torque.
[0056] Specifically, under the premise that the motor braking capacity value can meet the target braking torque requirements, if the torque actually generated by the motor braking can meet the target braking torque, the motor braking will be used first, that is, the motor braking system will be controlled to perform braking control based on the actual braking torque. At this time, the hydraulic braking system will stop working, and the target braking torque of the whole vehicle will be completely generated by the motor braking.
[0057] Furthermore, in some embodiments, after performing braking control on the current vehicle, it also includes: acquiring new braking information of the current vehicle, and adjusting the actual braking torque and / or target hydraulic braking torque of the motor according to the new braking information, and performing braking control according to the adjusted actual braking torque and / or target hydraulic braking torque of the motor.
[0058] Specifically, after the current vehicle is braked, the braking state of the vehicle is continuously monitored and new braking information of the current vehicle is obtained. The wire-controlled brake ECU will analyze the new braking information. If the new current electric motor braking torque can meet the new target required braking torque, the wire-controlled brake ECU will keep the new current electric motor braking torque unchanged and continue to use the new current braking torque for braking. If the current electric motor braking torque cannot meet the new target required braking torque, the new standard hydraulic braking torque is determined based on the difference between the new target required braking torque and the new current electric motor braking torque, and braking control is performed based on the new target hydraulic braking torque and the new current electric motor braking torque.
[0059] Therefore, by collecting the actual braking torque signal of the motor in real time, the regenerative braking system is coordinated to calculate whether the current actual total braking torque (motor braking torque + hydraulic braking torque) meets the total braking torque target requirement, and the hydraulic braking pressure is adjusted in real time to adjust the current actual total braking torque to meet the braking target requirement of the whole vehicle, ensuring that the braking deceleration does not change suddenly, improving braking smoothness, and providing users with a good braking experience.
[0060] According to the vehicle braking control method proposed in the embodiment of the present application, the target required braking torque is calculated based on the braking information, and when the actual braking torque of the motor does not meet the target required braking torque, the difference between the target required braking torque and the actual braking torque of the motor is calculated to obtain the target hydraulic braking torque, and the current vehicle is braked based on the actual braking torque of the motor and the target hydraulic braking torque. Therefore, by real-time monitoring of the actual braking torque of the motor and dynamically adjusting the intervention of the hydraulic brake, the problems of poor coordination, slow response speed and poor smoothness of the motor braking and hydraulic braking in the prior art are solved, thereby providing a smoother and more reliable braking experience.
[0061] Next, the braking control device of the vehicle proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.
[0062] Figure 3 It is a block diagram of a braking control device for a vehicle according to an embodiment of the present application.
[0063] like Figure 3 As shown, the vehicle braking control device 10 includes: a calculation module 100, a judgment module 200 and a control module 300.
[0064] Among them, the calculation module 100 is used to obtain the braking information of the current vehicle and calculate the target required braking torque based on the braking information; the judgment module 200 is used to obtain the actual braking torque of the motor and judge whether the actual braking torque of the motor meets the target required braking torque; the control module 300 is used to calculate the difference between the target required braking torque and the actual braking torque of the motor if the actual braking torque of the motor does not meet the target required braking torque, obtain the target hydraulic braking torque, and perform braking control on the current vehicle based on the actual braking torque of the motor and the target hydraulic braking torque.
[0065] Furthermore, in some embodiments, the control module 300 is used to: control the motor brake system of the current vehicle to perform braking control based on the actual braking torque, and control the hydraulic brake system to perform braking control based on the target hydraulic braking torque.
[0066] Furthermore, in some embodiments, after determining whether the actual braking torque of the motor meets the target required braking torque, the determination module 300 is further used to: if the actual braking torque of the motor meets the target required braking torque, control the motor braking system to perform braking control based on the actual braking torque.
[0067] Furthermore, in some embodiments, the braking information includes at least one of a brake pedal opening, a braking duration, a vehicle speed at the braking moment, and a current vehicle mass.
[0068] Furthermore, in some embodiments, after performing braking control on the current vehicle, the control module 300 is also used to: obtain new braking information of the current vehicle, and adjust the actual braking torque and / or target hydraulic braking torque of the motor according to the new braking information, and perform braking control according to the adjusted actual braking torque and / or target hydraulic braking torque of the motor.
[0069] It should be noted that the above explanation of the vehicle braking control method embodiment is also applicable to the vehicle braking control device of this embodiment, which will not be repeated here.
[0070] According to the vehicle braking control device proposed in the embodiment of the present application, the target required braking torque is calculated according to the braking information, and when the actual braking torque of the motor does not meet the target required braking torque, the difference between the target required braking torque and the actual braking torque of the motor is calculated to obtain the target hydraulic braking torque, and the current vehicle is braked based on the actual braking torque of the motor and the target hydraulic braking torque. Therefore, by real-time monitoring of the actual braking torque of the motor and dynamically adjusting the intervention of the hydraulic brake, the problems of poor coordination, slow response speed and poor smoothness of the motor braking and hydraulic braking in the prior art are solved, thereby providing a smoother and more reliable braking experience.
