[0015] When the motor vehicle is in a parking area, the parking area assist mode is entered;

[0016] In the parking area assist mode, adjusting the fuel injection timing and the ignition timing of the motor vehicle to keep the speed of the motor vehicle below a first speed threshold, and not responding to the driver's throttle request when the speed of the motor vehicle exceeds the first speed threshold;

[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0032] The parking assistance control method provided in this application can be applied to Figure 1In the control system shown, the Tbox (Telematics-BOX) system communicates with terminals via a network. Terminals can be, but are not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The Tbox system features 4G communication and positioning capabilities. Users can configure pre-stored information in the Tbox system through the terminal. The ECM (Engine Control Module) is one of the most important automotive electronic devices, continuously monitoring and controlling the normal operation of the engine. In modern engine management systems, the ECM is a core control component. It adjusts the vehicle's fuel injection and ignition timing according to varying engine operating conditions, ensuring optimal engine performance. The ABS (Anti-lock Brake System) automatically controls the braking force during braking to prevent the wheels from locking and maintain a rolling-slip state (with a slip ratio of approximately 20%), thereby ensuring maximum wheel adhesion to the road. The various systems are connected and information is transmitted via a communication bus.

[0033] In one embodiment, Figure 2 As shown, a parking assist control method is provided, with the ECM system as the execution body, and the steps of the method are introduced as follows:

[0034] Step S201, when the motor vehicle is located in a parking area, entering a parking area assistance mode;

[0035] Specifically, a positioning system installed on the vehicle, such as the Tbox system, is used to obtain the vehicle's current location in real time. By comparing the vehicle's current location with the user-defined parking area, it can determine whether the vehicle is in a parking area. When the vehicle enters a parking area from a non-parking area, the parking area assistance mode is entered.

[0036] In one embodiment, the parking assist mode can be triggered using a parking assist button. When the vehicle is in a parking area and the parking assist button is triggered, the parking assist mode is entered. The parking assist button can be triggered by a short period of time, a long period of time, or by induction. This can be achieved using devices such as a resettable switch, a self-locking switch, and an induction switch.

[0037] Step S202: In the parking area assistance mode, adjusting the fuel injection timing and ignition timing of the motor vehicle to keep the speed of the motor vehicle below a first speed threshold, and not responding to the driver's throttle request when the speed of the motor vehicle exceeds the first speed threshold;

[0038] Specifically, when a motor vehicle is in a parking area, it needs to find a suitable parking spot within the area. Other motor vehicles in the parking area affect the motor vehicle's route within the parking area. Therefore, the motor vehicle must maintain a low speed within the parking area. If the driver accidentally touches the accelerator, causing the vehicle to exceed the speed limit, it is easy for the motor vehicle to collide with other motor vehicles in the parking area, causing a safety accident.

[0039] The injection and ignition timings of a vehicle's engine vary under different operating conditions, affecting the engine's air-fuel ratio. In parking area mode, the vehicle's injection and ignition timings are adjusted to regulate the vehicle's speed, keeping it below a first speed threshold. Furthermore, the system does not respond to the driver's throttle request when the vehicle's speed exceeds the first speed threshold, ensuring safe, low-speed driving within parking areas.

[0040] Step S203, in the parking area assistance mode, if the motor vehicle enters the parking position, then enters the parking assistance mode;

[0041] Specifically, in the parking area assistance mode, when the driver finds a suitable parking position or the vehicle's route within the parking area is blocked, if the vehicle enters the parking position, the parking assistance mode is entered.

[0042] In one embodiment, the triggering of entering the parking assist mode can also be achieved by a parking assist button. In the parking area assist mode, if the parking assist button is triggered again, the parking assist mode is entered.

[0043] Step S204: In the parking assist mode, the vehicle enters a high torque output state and triggers the ABS system to actively brake when the speed of the vehicle is greater than a second speed threshold.

[0044] Specifically, in parking assist mode, when the driver maneuvers a vehicle into a parking space, they must accurately control the throttle based on environmental factors such as the size and terrain of the parking space to precisely park the vehicle. If there are obstacles such as thresholds, steps, or slopes that hinder the vehicle's entry into the parking space, a high-torque output state is activated to enable the vehicle to overcome these obstacles. Furthermore, during parking, the vehicle's speed must be strictly controlled due to its proximity to obstacles and other vehicles within the parking area. This triggers the ABS system to actively brake when the vehicle's speed exceeds a second speed threshold, quickly reducing the vehicle's speed. This prevents accidents such as collisions with obstacles or other vehicles within the parking area caused by insufficient throttle control and untimely braking.

[0045] The parking assist control method sequentially enters parking area assist mode and parking assist mode by monitoring the vehicle's position in real time. In parking area assist mode, the vehicle's fuel injection and ignition timing are adjusted to maintain the vehicle's speed below a first speed threshold. The method also discontinues responding to the driver's throttle input when the vehicle's speed exceeds the first speed threshold. This allows the vehicle to maintain a low and safe speed when entering a parking area, preventing the driver from accidentally overspeeding by touching the accelerator. In parking assist mode, the system enters a high-torque output state and triggers the ABS system to apply active braking when the vehicle's speed exceeds a second speed threshold. This provides high torque when encountering parking areas with thresholds or steps, and actively brakes when the vehicle's speed is excessive. Both operating modes reduce the risk of accidents such as collisions with obstacles or other vehicles within the parking area.

[0046] In one embodiment, when in parking assist mode, a high torque output state is entered, and the ABS system is triggered to actively brake when the speed of the motor vehicle is greater than a second speed threshold, including: when in parking assist mode, a high torque output state is entered, the ABS system is triggered to continuously monitor the rear wheel speed of the motor vehicle, and the ABS system is triggered to actively brake when it is detected that the rear wheel speed of the motor vehicle is greater than the second speed threshold.

[0047] In this embodiment, in the parking assist mode, the ABS system continuously monitors the rear wheel speed of the motor vehicle, and can timely control the speed of the motor vehicle, thereby improving the effectiveness and reliability of the parking assist control method of this application and improving the driving safety of the motor vehicle.

[0048] In one embodiment, the method provided by the present application also includes: when the motor vehicle is located in the parking area, the control indicator light is switched from the off state to the steady state; after the motor vehicle is located in the parking area and enters the parking area assistance mode, the control indicator light remains in the steady state; when entering the parking assistance mode, the control indicator light is switched from the steady state to the flashing state.

[0049] Specifically, the instrument panel is provided with an indicator light, which can be an LED indicator light or an indicator light symbol displayed on the instrument panel interface. The instrument panel's MCU can control the operating status of the indicator light, which is used to provide feedback on the vehicle's operating status so that the driver can understand the operating information of the vehicle being driven.

[0050] When the vehicle is in a parking area, the control indicator light switches from off to steady on, alerting the driver that the vehicle has entered the parking area. After the vehicle is in the parking area, the parking assist button is triggered, and the vehicle enters parking assist mode. The control indicator light remains steady on, alerting the driver that the vehicle is in parking assist mode. While in parking assist mode, if the parking assist button is triggered again, the control indicator light switches from steady on to flashing, alerting the driver that the vehicle is in parking assist mode.

[0051] In this embodiment, by controlling the change of the working state of the indicator light when the motor vehicle is in different states, the driver can fully understand the operating information of the motor vehicle being driven, thereby significantly improving the effectiveness of the parking assistance control method of this application and improving the driving safety of the motor vehicle.

[0052] In one embodiment, when a motor vehicle is located in a parking area, before entering a parking area assistance mode, the method provided by the present application further includes obtaining a parking area stored in the Tbox system; the parking area is pre-stored in the Tbox system by the user through an application.

[0053] Specifically, the parking area is stored as an invalid value by default after leaving the factory, and the user can modify the parking area pre-stored in the Tbox system through the application.

[0054] In one embodiment, in the parking area assistance mode, if a motor vehicle enters a parking position, before entering the parking assistance mode, the method provided in the present application also includes: obtaining the parking position stored in the Tbox system; the parking position is pre-stored in the Tbox system by the user through the application.

[0055] Specifically, the parking location is stored as an invalid value by default after leaving the factory, and users can modify the parking area pre-stored in the Tbox system through the application.

[0056] In one embodiment, before not responding to the driver's throttle request when the speed of the motor vehicle is greater than a first speed threshold, the method further includes: obtaining the first speed threshold stored in the Tbox system; the first speed threshold is pre-stored in the Tbox system by the user through an application.

[0057] Specifically, the first vehicle speed threshold is a default value after leaving the factory, and the user can modify the first vehicle speed threshold pre-stored in the Tbox system through the application.

[0058] In one embodiment, before triggering the ABS system to actively brake when the speed of the motor vehicle is greater than a second speed threshold, the method provided in the present application also includes: obtaining the second speed threshold stored in the Tbox system; the second speed threshold is pre-stored in the Tbox system by the user through an application.

[0059] Specifically, the second vehicle speed threshold is a default value after leaving the factory, and the user can modify the second vehicle speed threshold pre-stored in the Tbox system through the application.

[0060] In order to better understand the above method, an application example of the parking assistance control method of the present application is described in detail below.

[0061] First, users can set the parking area, parking location, first speed threshold and second speed threshold pre-stored in the Tbox system through the application on their smartphones according to actual needs.

[0062] Secondly, when the motor vehicle is in a normal driving state, the positioning system of the motor vehicle obtains the current position of the motor vehicle in real time. Figure 3 The parking assist mode and its application area diagram shown compare the vehicle's current location with the user-defined parking area. When the vehicle enters a parking area from a non-parking area, the control indicator light switches from off to steady on, alerting the driver that the vehicle has entered the parking area, i.e., the application area of parking assist mode. If the vehicle enters parking assist mode, the control indicator light remains steady on, alerting the driver that the vehicle is in parking assist mode.

[0063] In the parking area assist mode, the fuel injection timing and the ignition timing of the motor vehicle are adjusted to keep the vehicle speed below a first vehicle speed threshold, and the driver's throttle request is not responded to when the vehicle speed is greater than the first vehicle speed threshold.

[0064] In parking area assist mode, if the vehicle enters a parking position, it enters parking assist mode. The control indicator light switches from a constant on state to a flashing state to let the driver know that the vehicle is in parking assist mode.

[0065] When in parking assist mode, the system enters a high-torque output state, triggering the ABS system to continuously monitor the vehicle's rear wheel speed to enable the vehicle to overcome environmental obstacles. The ABS system also triggers active braking to quickly reduce the vehicle's speed when it detects that the vehicle's rear wheel speed exceeds a second speed threshold.

[0066] This embodiment sequentially enters parking area assist mode and parking assist mode by monitoring the vehicle's position in real time. In parking area assist mode, the vehicle's fuel injection and ignition timing are adjusted to maintain the vehicle's speed below a first speed threshold. The system does not respond to the driver's throttle request when the vehicle's speed exceeds the first speed threshold. This allows the vehicle to maintain a safe low speed when entering a parking area, preventing the driver from accidentally touching the accelerator and causing the vehicle to overspeed. In parking assist mode, the system enters a high-torque output state and triggers the ABS system to actively brake when the vehicle's speed exceeds a second speed threshold. This provides high torque when the vehicle encounters parking terrain with thresholds or steps, and actively brakes when the vehicle's speed is too high, reducing the risk of accidents.

[0067] It should be understood that, although the steps in the flowcharts of the above embodiments are shown in sequence as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts of the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily to be performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
