Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle starter control method, device, equipment and medium. Background Technology

[0002] The starter motor is an important device for starting the engine. The starter motor uses the electrical energy from the battery to drive the gears to generate mechanical energy. The transmission structure then engages the drive gears with the flywheel ring gear, which drives the engine to run. Once the engine reaches the required speed to start, the starter motor automatically disengages.

[0003] During vehicle use, starter motor burnout and solenoid switch burnout are common malfunctions. According to vehicle after-sales repair data, starter motor failures include motor burnout, solenoid switch burnout, and gear failure, but the most common cause is misalignment between the starter motor drive gear and the engine flywheel ring gear. In this case, the engine does not start, but the starter motor has been running for an extended period, leading to the burnout of the starter solenoid switch.

[0004] Existing technology controls the starter motor's activation based on the status information of the starter motor and engine. However, the existing control method requires the addition of a temperature sensor, and the temperature control has a certain lag, resulting in poor system reliability and failure to protect the starter motor solenoid switch. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0035] Example 1

[0036] Figure 1 This is a flowchart illustrating a vehicle starter motor control method according to Embodiment 1 of the present invention. This embodiment is applicable to situations involving the protection of a vehicle starter motor. The method can be executed by a vehicle starter motor control device, which can be implemented in hardware and / or software and can be configured in a computer. Figure 1 As shown, the method includes:

[0037] S110. Obtain the current vehicle's attribute information and starting interval, and generate a starting signal based on the attribute information and starting interval.

[0038] The starter motor converts the electrical energy stored in the battery into mechanical energy, specifically by generating power from a DC motor. This power drives the engine crankshaft via a transmission mechanism, thus starting the engine. The starting system includes the following components: battery, ignition switch (starter switch), starter assembly, and starter relay. When controlling the starter, the controller first acquires the vehicle's current attribute information and starting interval. The attribute information includes vehicle status information and engine speed information. Vehicle status information includes gear position information, brake pedal position information, and ignition switch position information. Engine speed refers to the number of revolutions per minute of the engine crankshaft. The starting interval is the time interval between the current start and the last start. When the attribute information and starting interval meet the starting conditions, a starting signal is generated. This starting signal is the signal that controls the starter motor to begin operation.

[0039] In a specific implementation, this method can be applied to a starter motor operation protection control system, including a starter protection controller. The protection controller includes a speed acquisition module, a control output module, and a voltage acquisition module. The entire circuit also includes components such as a battery, ignition switch, crankshaft speed sensor, starter protection control module, fuse, starter relay, voltage acquisition point, soft engagement relay, electromagnetic switch attraction coil, electromagnetic switch holding coil, motor, and fuse.

[0040] Specifically, when the driver presses the ignition key, the ignition switch closes. The control module determines if the starting conditions are met and activates the relay. The electromagnetic switch's attraction and holding coils work simultaneously, and the electromagnetic force pulls the starter motor's internal shift fork, engaging the drive gear with the engine gear ring. The starter motor then performs a meshing process. Once a certain engagement depth is reached, the electromagnetic switch contacts close, short-circuiting the attraction coil. The electric motor is then directly connected to the battery, providing greater torque to drive the engine. This embodiment adds a voltage acquisition signal to the existing starting system, considering the possibility of poor meshing between the drive gear and engine gear. When the voltage exceeds a certain fixed value, successful meshing is determined; otherwise, the gear is considered to be misaligned, thus preventing the electromagnetic switch from burning out.

[0041] S120. Control the vehicle starter motor to start according to the start signal and obtain start-related information, including the start duration of a single start, engine speed and relay voltage.

[0042] Specifically, the starter motor can be controlled to start based on the start signal and start-related information can be obtained. The start-related information includes the duration of a single start, engine speed, and relay voltage. The relay voltage includes the voltage before the electromagnetic switch is engaged and the voltage after the electromagnetic switch is engaged.

[0043] S130. When the start-related information meets the reset conditions, a reset signal is generated, and the starter motor is controlled to disconnect according to the reset signal.

[0044] The reset conditions include a single start-up duration greater than a first preset threshold, an engine speed lower than a first speed threshold or higher than a second speed threshold within a first specified time, and a voltage difference less than or equal to a preset difference threshold.

[0045] Figure 2 This invention provides a flowchart of a vehicle starter control method according to Embodiment 1. Step S130 mainly includes the following steps S131 to S138:

[0046] S131. Determine whether the single start-up duration is greater than the first preset threshold. If yes, execute S132; otherwise, execute S133.

[0047] S132. Directly generate a reset signal, and control the starter motor to disconnect according to the reset signal.

[0048] Specifically, when the duration of a single start-up exceeds a first preset threshold, the controller will directly generate a reset signal, thereby controlling the starter motor to disconnect. The first preset threshold is determined by the controller based on the temperature collected by the ambient temperature sensor, and the software will automatically adjust it within 10-30 seconds. For example, the first preset threshold can be 30 seconds, meaning that the starter motor will stop working if the duration of a single start-up exceeds 20 seconds.

[0049] S133. Determine whether the engine speed is lower than the first speed threshold or higher than the second speed threshold within the first specified time. If yes, execute S134; otherwise, execute S135-S136.

[0050] Specifically, the first specified time is determined by the controller based on the temperature collected by the ambient temperature sensor, causing the software to automatically adjust within 1-5 seconds. The first and second speed thresholds are set by the user according to engine performance, with the second speed threshold being higher than the first. The second speed threshold refers to the idle speed. It should be noted that the second speed threshold should be set as low as possible while still being above the engine's minimum starting speed to avoid the engine dragging the starter motor. For example, the first specified time could be 5 seconds, the first speed threshold could be 50 rpm, and the second speed threshold could be 400 rpm. When the engine speed approaches the idle speed of 400 rpm, operation stops. When the starter motor operates for 5 seconds and the engine speed is below 50 rpm, operation stops.

[0051] S134. Generate a reset signal and control the starter motor to disconnect according to the reset signal.

[0052] S135. Determine the voltage difference between the voltage after the electromagnetic switch is activated and the voltage before the electromagnetic switch is activated within the second specified time period.

[0053] Specifically, the starter motor includes an electromagnetic switch, a soft-engagement relay, an electromagnetic switch, a motor, a shift fork, a commutator, and drive teeth. The voltage before the electromagnetic switch engages can be read at the front end of the soft-engagement relay. After the relay is turned on, the electromagnetic switch's engagement coil and holding coil will have a current of about 200A. Due to the internal resistance of the battery, the voltage after the electromagnetic switch engages will change at the front end of the soft-engagement relay. When the drive teeth engage with the flywheel ring gear, the electromagnetic switch coil is continuously energized. When the drive teeth and flywheel ring gear are properly engaged, the starter motor will work. The voltage difference will generally increase by more than 1.6V within 500ms. Therefore, by monitoring the voltage at the front end of the starter relay, the electromagnetic switch can be protected.

[0054] S136. Determine whether the voltage difference is less than or equal to the preset difference threshold. If yes, execute S137; otherwise, execute S138.

[0055] S137. Generate a reset signal and control the starter motor to disconnect according to the reset signal.

[0056] Specifically, the preset difference threshold can be determined based on a large amount of historical data showing the starter motor and engine working together. The preset difference threshold can be 1.6V. If the voltage difference does not increase by 1.6V within 500ms, the start signal is disconnected, the starter motor stops working, and the electromagnetic switch is prevented from burning out.

[0057] Detailed Implementation: This implementation can determine whether the starting conditions of the starter are met based on the vehicle status and engine speed information. The starting conditions include the gear being in neutral, the brake pedal being in the brake position, the engine speed being zero, and the key being in the ST position. When the above conditions are met, a start signal is sent. After the start signal is sent, if two starts are less than a fixed interval, or if the engine speed is lower than a first fixed speed limit or greater than a second fixed speed limit within a fixed time, or if the duration of a single start is greater than a fixed value, or if the collected voltage U2 rises less than 1.6V within 500ms, a reset signal is sent, and the controller will control the starter relay to disconnect.

[0058] S138. Generate a starter motor normal operation signal and send the normal operation signal to the user terminal for display.

[0059] Specifically, when the starter motor is operating normally, the controller will also generate a starter motor normal operation signal and send it to the user terminal for display, ensuring that the user is aware of the starter motor's working status in a timely manner.

[0060] The technical solution of this invention obtains the current vehicle attribute information and starting interval, then generates a starting signal based on the attribute information and starting interval to control the vehicle starter motor to start. Then, it determines whether the reset condition is met by obtaining the single starting duration, engine speed and relay voltage. When the reset condition is met, a reset signal is generated to control the starter motor to disconnect. The system has high reliability, effectively solves the problems of electromagnetic switch burnout and motor burnout, and improves the service life of the starter motor.

[0061] Example 2

[0062] Figure 3 This is a flowchart of a vehicle starter control method provided in Embodiment 2 of the present invention. This embodiment adds a specific process for generating a starter signal based on attribute information and starter interval, building upon Embodiment 1. For example... Figure 3 As shown, the method includes:

[0063] S210. Obtain the current vehicle's attribute information and start interval.

[0064] S220. When the starting interval is greater than the preset time interval, obtain the starting conditions of the starter motor, wherein the starting conditions include the gear being in neutral, the brake pedal being in the brake position, the engine speed being zero, and the ignition switch being in the ST position.

[0065] S230. When the attribute information meets the starting conditions, a starting signal is generated, wherein the attribute information includes vehicle status information and engine speed information.

[0066] Specifically, the preset time interval can be 15 seconds. This means that the starter motor is only allowed to operate if the interval between two consecutive starts is greater than 15 seconds. Furthermore, a start signal will only be generated to control the starter motor when the attribute information meets the starting conditions: the gear is in neutral, the brake pedal is in the brake position, the engine speed is 0, and the ignition switch is in the ST position. It should be noted that all starting conditions must be met for the starter motor to begin operating, while the reset condition only requires meeting any one of them; the controller will then disconnect the start signal to stop the starter motor from operating, preventing damage to the solenoid switch.

[0067] This invention utilizes resources such as engine speed signal, brake pedal position information, gear information, ignition switch information, starting duration information, secondary starting interval duration information, starting signal, ambient temperature information, and starter control voltage information to make a comprehensive judgment, thereby starting and stopping the starter.

[0068] Optionally, the method also includes: generating a prompt message based on the attribute information when the attribute information does not meet the start-up conditions; and triggering an alarm in a specified manner based on the prompt message.

[0069] Specifically, when the attribute information does not meet the starting conditions, the controller can generate a prompt message based on the attribute information. Furthermore, the controller will issue an alarm in a specified manner based on the prompt message. The alarm is to alert the user, allowing them to promptly understand the starter motor's inability to start normally, and enabling the user to check and adjust the gear position, brake pedal, engine speed, and ignition switch to ensure the starter motor operates normally subsequently. The specified methods include voice or image. Voice can be broadcast through a speaker connected to the controller; for example, the voice message could be: "Ignition switch position is not up to standard." Images can be displayed through a user terminal connected to the controller to alert the user.

[0070] S240. Control the vehicle starter motor to start according to the start signal and obtain start-related information, including the start duration, engine speed and relay voltage.

[0071] S250: When the start-related information meets the reset conditions, a reset signal is generated, and the starter motor is controlled to disconnect according to the reset signal.

[0072] Optionally, the reset conditions include a single start duration exceeding a first preset threshold. When start-related information meets the reset conditions, a reset signal is generated, including: determining whether the single start duration exceeds the first preset threshold; if so, directly generating a reset signal; otherwise, generating a reset signal when the engine speed or relay voltage meets the reset conditions, wherein the relay voltage includes the voltage before the electromagnetic switch is engaged and the voltage after the electromagnetic switch is engaged.

[0073] Optionally, the reset condition includes the engine speed being lower than a first speed threshold or higher than a second speed threshold within a first specified time. When the engine speed or relay voltage meets the reset condition, a reset signal is generated, including: determining whether the engine speed is lower than the first speed threshold or higher than the second speed threshold within the first specified time; if so, generating a reset signal, wherein the second speed threshold is higher than the first speed threshold; otherwise, generating a reset signal when the relay voltage meets the reset condition.

[0074] Optionally, the reset condition includes a voltage difference less than or equal to a preset difference threshold. When the relay voltage meets the reset condition, a reset signal is generated, including: determining the voltage difference between the voltage after the electromagnetic switch is energized and the voltage before the electromagnetic switch is energized within a second specified time; and generating a reset signal when the voltage difference is less than or equal to the preset difference threshold.

[0075] Optionally, the method also includes: generating a starter normal operation signal when the voltage difference is greater than a preset difference threshold; and sending the normal operation signal to the user terminal for display.

[0076] The technical solution of this invention obtains the current vehicle attribute information and starting interval, then generates a starting signal based on the attribute information and starting interval to control the vehicle starter motor to start. Then, it determines whether the reset condition is met by obtaining the single starting duration, engine speed and relay voltage. When the reset condition is met, a reset signal is generated to control the starter motor to disconnect. The system has high reliability, effectively solves the problems of electromagnetic switch burnout and motor burnout, and improves the service life of the starter motor.
