Description

Technical Field

[0001] This invention relates to the field of parking control, and in particular to a parking reminder control method, system, and electric vehicle. Background Technology

[0002] Current electric vehicles generally possess a crawl function, which allows the vehicle to travel at a very slow, constant speed, similar to idling in a traditional gasoline car, without the driver pressing the accelerator pedal. The crawl function can be turned on or off as needed. When turned off, the electric vehicle remains stationary due to energy recovery and friction. However, if the driver does not promptly park the vehicle after it has come to a stop, current technology typically does not provide a parking warning, leading to a high probability that the driver will forget to park. When the vehicle is on a slope, there is a significant risk of it rolling away, posing a substantial safety hazard.

[0015] When the vehicle speed is less than the first speed threshold, the preset first timer is started to begin timing, and the timing duration is obtained in real time;

[0016] If the timing duration reaches the first time threshold, the vehicle speed will be determined to be less than the first speed threshold.

[0026] In one implementation, when the vehicle's parking alarm is active, the method further includes:

[0027] Start the preset second timer to begin timing and obtain the timing duration in real time;

[0028] If the timeout period reaches the second time threshold, the vehicle parking reminder control process will be cancelled and the vehicle parking alarm will be turned off.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Current electric vehicles generally possess a crawl function, which allows the vehicle to travel at a very slow, constant speed, similar to idling in a traditional gasoline car, without the driver pressing the accelerator pedal. The crawl function can be turned on or off as needed. When turned off, the electric vehicle remains stationary due to energy recovery and friction. However, if the driver does not promptly park the vehicle after it has come to a stop, current technology typically does not provide a parking warning, leading to a high probability that the driver will forget to park. When the vehicle is on a slope, there is a significant risk of it rolling away, posing a substantial safety hazard.

[0055] In summary, existing technologies lack corresponding control processes for parking reminder control of vehicles with creep function. Therefore, this invention provides a parking reminder control method, system, and electric vehicle. This method can provide parking reminder control for vehicles with creep function in various scenarios, and can promptly provide parking alarm prompts to the driver after the vehicle comes to a stop, reducing the risk of the vehicle rolling away.

[0056] To facilitate understanding of this embodiment, a parking reminder control method disclosed in this invention will first be described in detail. This method is applied to vehicles with creeping functionality. Figure 1As shown, the parking reminder control method includes:

[0057] Step S101: When the crawl function is detected to be off, determine whether the vehicle speed is less than the first speed threshold.

[0058] Crawl control is a common feature in electric vehicles. With crawl control enabled, the vehicle can move at a very slow, constant speed without the driver pressing the accelerator pedal, similar to idling in a traditional gasoline car. Crawl control can be turned on or off as needed. When crawl control is off, the electric vehicle will remain stationary due to energy recovery and friction.

[0059] In a specific scenario, after the driver manually turns off the crawl function, the relevant controller can detect that the crawl function is off. This current state can be understood as a prerequisite for the parking reminder control method to be activated.

[0060] This step requires determining whether the vehicle speed is less than a first speed threshold. The first speed threshold can be understood as a parameter that measures whether the vehicle is in a very slow driving state. When the vehicle speed is less than the first speed threshold, it indicates that the vehicle is about to stop and the subsequent step of activating the parking alarm reminder needs to be executed. If the vehicle speed is greater than the first speed threshold, it indicates that the vehicle is still in a driving state and the parking alarm reminder does not need to be activated.

[0061] Step S102: If the vehicle speed is less than the first speed threshold, determine whether the vehicle's accelerator pedal sensor has collected an acceleration signal.

[0062] If the vehicle speed is less than the first speed threshold, it indicates that the vehicle is about to stop, and the subsequent steps to activate the parking warning reminder need to be executed. At this time, it is necessary to determine whether the vehicle's accelerator pedal sensor has detected an acceleration signal. The accelerator pedal sensor is located in the accelerator pedal and is used to measure whether the driver has pressed the accelerator pedal. Obviously, if the vehicle's accelerator pedal sensor detects an acceleration signal, it means that the driver has pressed the accelerator pedal, and the vehicle is in an acceleration state, so there is no need to activate the parking warning reminder.

[0063] Step S103: If the accelerator pedal sensor does not collect an acceleration signal, determine whether the vehicle's brake pedal sensor has collected a braking signal.

[0064] If the accelerator pedal sensor does not detect an acceleration signal, it indicates that the driver has not pressed the accelerator pedal, and the vehicle is stationary or nearly stationary. Generally, parking maneuvers require the vehicle to be stationary before the brake pedal can be depressed to bring the vehicle to a stop. Therefore, this step requires determining whether the brake pedal sensor has detected a braking signal to ascertain whether the vehicle is stationary or nearly stationary.

[0065] Step S104: If the brake pedal sensor does not collect a braking signal, activate the vehicle's parking alarm reminder.

[0066] If the brake pedal sensor does not detect a braking signal, combined with all the conditions in the above steps, namely: the vehicle speed is less than the first speed threshold and the accelerator pedal sensor does not detect an acceleration signal, the vehicle's parking alarm will be activated to remind the user to perform parking operations when the above conditions are met.

[0067] As can be seen from the parking reminder control method mentioned in the above embodiments, this method can perform parking reminder control for vehicles with creep function in various scenarios, and can provide the driver with a parking alarm prompt in a timely manner after the vehicle stops, reducing the risk of the vehicle rolling away.

[0068] This parking alert control method essentially provides a reminder during the parking process. In real-world scenarios, users typically perform the parking operation only after the vehicle has come to a complete stop, and after stopping, they usually release the brake pedal. Therefore, it is necessary to determine the parking status. In one implementation, if the brake pedal sensor does not detect a braking signal, step S104 activates the vehicle's parking alarm reminder. Figure 2 As shown, it includes:

[0069] Step S201: If the brake pedal sensor does not collect a braking signal, determine whether the vehicle's parking sensor has collected a parking signal; wherein, the parking sensor is located on the vehicle's parking pedal, mechanical handbrake, or electronic handbrake.

[0070] Step S202: If the parking sensor does not collect a parking signal, the vehicle's parking alarm is activated.

[0071] The driver has controlled the vehicle's speed below the first speed threshold. At this point, the vehicle is mostly stationary. Although the brake pedal sensor has not detected a braking signal, the vehicle will remain stationary due to friction and regenerative braking because the crawl function is disabled. Drivers often use regenerative braking when driving this type of tram, thus reducing the use of the brake pedal. After driving for a long time, they may easily forget to manually park the vehicle.

[0072] Therefore, if the parking sensor does not collect a parking signal, it indicates that the driver has not performed a parking operation, and the vehicle's parking alarm reminder needs to be activated.

[0073] In the process of using a first speed threshold for parking reminder control, relevant time judgment parameters need to be added to ensure the reliability of the parking reminder control. In one implementation, it is determined whether the vehicle speed is less than the first speed threshold, such as... Figure 3 As shown, it includes:

[0074] Step S301: When the vehicle speed is less than the first speed threshold, start the preset first timer to begin timing and obtain the timing duration in real time;

[0075] In step S302, if the timing duration reaches the first time threshold, it will be determined that the vehicle speed is less than the first speed threshold.

[0076] Specifically, the first speed threshold can be set to 1 km / h, and the first time threshold can be set to 2 seconds. When the vehicle speed is less than 1 km / h and lasts for 2 seconds, it is considered that the vehicle speed is less than the first speed threshold, and subsequent steps to determine whether the vehicle's accelerator pedal sensor has collected an acceleration signal are executed.

[0077] The core idea of ​​the above process can be understood as follows: the parking alarm is only activated when the driver manually disables the crawl function. The parking alarm is activated if the vehicle speed is below a first speed threshold, and the accelerator pedal sensor does not detect an acceleration signal, the brake pedal sensor does not detect a braking signal, and the parking sensor does not detect a parking signal. It is worth noting that all of the above conditions must be met simultaneously for the parking alarm to be activated.

[0078] When the parking alarm is active, it needs to be canceled based on relevant judgment conditions. Specifically, in one implementation, when the vehicle's parking alarm is active, the parking alarm control method further includes: when the creep function is detected to be activated, canceling the vehicle's parking alarm control process and turning off the vehicle's parking alarm.

[0079] In this scenario, the driver actively activated the crawl function after being alerted by the parking alarm, thereby controlling the vehicle to drive at a low speed and eliminating the need for parking. Therefore, the parking alarm control process is canceled and the parking alarm is turned off.

[0080] In one implementation, when the vehicle's parking alarm reminder is active, the parking reminder control method further includes: when the vehicle's parking sensor detects that a parking signal has been collected, canceling the vehicle's parking reminder control process and turning off the vehicle's parking alarm reminder.

[0081] In this scenario, the driver performs a parking operation under the guidance of the parking alarm, such as pulling the handbrake or pressing the parking pedal to control the vehicle. Therefore, the parking alarm control process is canceled and the vehicle's parking alarm is turned off.

[0082] In one embodiment, when the vehicle's parking alarm reminder is active, the parking reminder control method further includes: when the brake pedal sensor detects that a braking signal has been collected, canceling the vehicle's parking reminder control process and turning off the vehicle's parking alarm reminder.

[0083] In this scenario, the driver actively presses the brake pedal after being alerted by the parking alarm, which reduces the risk of the vehicle rolling away. Therefore, the vehicle's parking alarm control process is canceled and the vehicle's parking alarm is turned off.

[0084] In one embodiment, when the vehicle's parking alarm reminder is active, the parking reminder control method further includes: when the accelerator pedal sensor detects an acceleration signal, determining whether the vehicle speed is greater than a second speed threshold; wherein the second speed threshold is greater than a first speed threshold; if the vehicle speed is greater than the second speed threshold, canceling the vehicle's parking reminder control process and turning off the vehicle's parking alarm reminder.

[0085] In this scenario, although the driver receives a parking alarm reminder, the driver actively presses the accelerator pedal to accelerate. When the vehicle speed exceeds the second speed threshold, such as 2 km / h, it indicates that the vehicle is in a normal driving state. Therefore, the vehicle parking reminder control process is canceled and the vehicle parking alarm reminder is turned off.

[0086] In one embodiment, when the vehicle's parking alarm reminder is active, the parking reminder control method further includes: starting a preset second timer to begin timing and acquiring the timing duration in real time; if the timing duration reaches a second time threshold, canceling the vehicle's parking reminder control process and turning off the vehicle's parking alarm reminder.

[0087] In this scenario, although the driver receives a parking alarm notification, the parking alarm sound is generally quite jarring. To reduce the discomfort caused by the parking alarm sound to the driver, the parking alarm notification process is canceled and the parking alarm notification is turned off when the parking alarm notification time exceeds the second time threshold.

[0088] The above process is as follows: Figure 4 As shown, first, it checks if the crawl function is disabled; if not, it re-executes; if so, it checks if: the vehicle speed is less than 1 km / h for more than 2 seconds; the driver has not pressed the parking pedal; the driver has not pressed the brake pedal; and the driver has not pressed the accelerator pedal. If all of the above conditions are met, the parking alarm is activated; if any of the above conditions are not met, the check is repeated.

[0089] Once the parking warning is activated, the system will determine the following: whether the parking warning has lasted for more than 10 seconds; whether the crawl function has been activated; whether parking has been completed; whether the driver has pressed the brake pedal; or whether the driver has pressed the accelerator pedal and the vehicle speed is greater than 2 km / h. If any of the above conditions are met, the parking warning will be deactivated.

[0090] As can be seen from the parking reminder control method mentioned in the above embodiments, this method can perform parking reminder control for vehicles with crawl function in various scenarios, can realize the parking reminder process on models without active parking function, and can provide the driver with parking alarm prompts in a timely manner after the vehicle stops, reducing the risk of vehicle rollaway.

[0091] Regarding the parking reminder control method provided in the foregoing embodiments, this invention provides a parking reminder control system, which is applied to vehicles with crawling functionality, such as... Figure 5 As shown, the parking reminder control system includes:

[0093] The second judgment module 520 is used to determine whether the vehicle's accelerator pedal sensor has collected an acceleration signal if the vehicle speed is less than the first speed threshold.

[0097] In one embodiment, the first judgment module 510, in the process of judging whether the vehicle speed is less than the first speed threshold, is further configured to: when the vehicle speed is less than the first speed threshold, start a preset first timer to start timing and obtain the timing duration in real time; if the timing duration reaches the first time threshold, determine that the vehicle speed is less than the first speed threshold.

[0098] In one embodiment, the parking reminder control system further includes a fifth judgment module; the fifth judgment module, when the vehicle's parking alarm reminder is in an active state, is used to: cancel the vehicle's parking reminder control process and turn off the vehicle's parking alarm reminder when it detects that the crawl function is activated.

[0099] In one embodiment, the parking reminder control system further includes a sixth judgment module; the sixth judgment module, when the vehicle's parking alarm reminder is in an active state, is used to: cancel the vehicle's parking reminder control process and turn off the vehicle's parking alarm reminder when the vehicle's parking sensor detects that a parking signal has been collected.

[0100] In one embodiment, the parking reminder control system further includes a seventh judgment module; the seventh judgment module, when the vehicle's parking alarm reminder is in an active state, is used to: cancel the vehicle's parking reminder control process and turn off the vehicle's parking alarm reminder when the brake pedal sensor detects that a braking signal has been collected.

[0101] In one embodiment, the parking reminder control system further includes an eighth judgment module; the eighth judgment module, when the vehicle's parking alarm reminder is in an active state, is used to: when the accelerator pedal sensor detects an acceleration signal, determine whether the vehicle speed is greater than a second speed threshold; wherein the second speed threshold is greater than a first speed threshold; if the vehicle speed is greater than the second speed threshold, cancel the vehicle's parking reminder control process and turn off the vehicle's parking alarm reminder.

[0102] In one embodiment, the parking reminder control system further includes a ninth judgment module; when the vehicle's parking alarm reminder is in an active state, the ninth judgment module is used to: start a preset second timer to begin timing and obtain the timing duration in real time; if the timing duration reaches a second time threshold, then cancel the vehicle's parking reminder control process and turn off the vehicle's parking alarm reminder.
