Description

Technical Field

[0001] This utility model relates to controllers, and more particularly to a motorcycle idle start-stop controller with sleep control. Background Technology

[0002] With the development of the motorcycle industry, designers are paying more and more attention to the energy management of motorcycle controllers. The battery is the energy source of the controller. When the vehicle engine stops and the user forgets to turn off the power switch, the vehicle controller, such as the Hall power supply module, half-bridge drive module and CAN communication module, will remain powered on and continuously consume power. At the same time, the vehicle engine cannot start and cannot charge the battery. Since the above-mentioned controllers consume a lot of power, the vehicle battery will be depleted quickly. At this time, the vehicle will not be able to start, and it will also have a significant impact on the battery life and normal use of the motorcycle. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a motorcycle idle start-stop controller with sleep control, which has the advantage of good energy saving effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a motorcycle idle start-stop controller with sleep control, including: a sleep control module, a Hall power supply module, a half-bridge drive module, a CAN communication module, a starter generator, an MCU, and a power switch for controlling the vehicle power supply. The Hall power supply module, the half-bridge drive module, and the CAN communication module are electrically connected to the sleep control module. The starter generator is equipped with a Hall sensor. The MCU is electrically connected to the sleep control module and the Hall sensor. When the power switch is closed, the Hall power supply module can supply power to the Hall sensor. The MCU can detect the working status of the starter generator through the Hall sensor. If the starter generator is in a stopped state, the MCU can input a sleep electrical signal to the sleep control module. The sleep control module can control the Hall power supply module, the half-bridge drive module, and the CAN communication module to enter sleep mode according to the received sleep electrical signal.

[0005] Optionally, the MCU includes a timer, and the sleep control module includes at least one switching transistor. When the MCU detects that the starter motor is stopped via a Hall sensor and the timer detects that the stop duration of the starter motor meets a set value, the MCU can send a sleep signal to the base of the switching transistor and the mode selection port of the CAN communication module. The collector of the switching transistor is electrically connected to the enable terminal of the Hall power supply module and the enable terminal of the half-bridge drive module. The sleep signal can control the switching transistor to turn on and drive the Hall power supply module and the half-bridge drive module to enter sleep mode. The sleep signal can also control the CAN communication module to enter sleep mode.

[0006] Optionally, the system also includes an ECU, which is electrically connected to a CAN communication module, and a half-bridge drive module is electrically connected to a starter generator motor.

[0007] Optionally, a voltage regulator is provided between the MCU and the battery, and a voltage divider resistor is provided between the mode selection port of the CAN communication module and the MCU.

[0008] Optionally, the number of switching transistors is two, with one switching transistor corresponding to the Hall power supply module and the half-bridge drive module.

[0009] Alternatively, the switching transistor can be replaced with a MOSFET.

[0010] The beneficial technical effects of this utility model are as follows: The motorcycle idle start-stop controller with sleep control includes: a sleep control module, a Hall power supply module, a half-bridge drive module, a CAN communication module, a starter generator, an MCU, and a power switch for controlling the vehicle's power supply. In use, the MCU detects whether the motorcycle engine is running through a Hall sensor located on the starter generator. If the engine is not running, the MCU sends a sleep signal. Upon receiving the sleep signal, the sleep control module controls the Hall power supply module, the half-bridge drive module, and the CAN communication module to enter sleep mode. This reduces the motorcycle's standby power consumption when the user turns on the power switch but the engine is not running or is in a start-stop state, thus saving battery power. It has the advantage of good energy-saving performance. Attached Figure Description

[0012] Figure 2 This is a flowchart of the process of this utility model; Detailed Implementation

[0013] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0014] This specific embodiment details the motorcycle idle start-stop controller with sleep control described in this application, such as... Figure 1 As shown, the motorcycle idle start-stop controller with sleep control includes: a sleep control module, a Hall power supply module, a half-bridge drive module, a CAN communication module, a starter generator, an MCU, and a power switch for controlling the vehicle's power supply. The Hall power supply module, the half-bridge drive module, and the CAN communication module are electrically connected to the sleep control module. The starter generator is equipped with a Hall sensor. The MCU is electrically connected to the sleep control module and the Hall sensor. When the power switch is closed, the Hall power supply module can supply power to the Hall sensor. The MCU can detect the operating status of the starter generator through the Hall sensor. If the starter generator is in a stopped state, the MCU can input a sleep signal to the sleep control module. The sleep control module can control the Hall power supply module, the half-bridge drive module, and the CAN communication module to enter sleep mode according to the received sleep signal. In operation, the MCU detects whether the motorcycle engine is running via a Hall sensor installed on the starter motor. If the engine is not running, the MCU sends a sleep signal. Upon receiving this signal, the sleep control module controls the Hall power supply module, half-bridge drive module, and CAN communication module to enter sleep mode. This reduces standby power consumption when the user turns on the power switch but the engine is not running or is in a start-stop state, thus saving battery power. It offers the advantage of good energy saving.

[0015] Optionally in this embodiment, the MCU is equipped with a timer, and the sleep control module is equipped with at least one switching transistor. When the MCU detects that the starter generator is in a stopped state through the Hall sensor and detects that the stop duration of the starter generator meets the set value through the timer, the MCU can send a sleep signal to the base of the switching transistor and the mode selection port of the CAN communication module. The collector of the switching transistor is electrically connected to the enable terminal of the Hall power supply module and the enable terminal of the half-bridge drive module. The sleep signal can control the switching transistor to turn on and drive the Hall power supply module and the half-bridge drive module to enter the sleep mode. The sleep signal can also control the CAN communication module to enter the sleep mode. Because of the transmission connection between the engine and the starter generator, the starter generator can also be driven to rotate when the engine is running. When the engine is off, the starter generator does not rotate. The engine is running by detecting whether the starter generator is rotating. When the Hall sensor detects that the starter generator has stopped, the timer starts counting. When the time reaches the preset value, the MCU sends a sleep signal. The timer can prevent the MCU from frequently sending sleep signals and avoid frequently entering sleep mode during normal use of the motorcycle. The Hall power supply module, half-bridge drive module and CAN communication module will only go into sleep mode after the motorcycle engine has not been started for a certain period of time.

[0016] Optionally, this embodiment also includes an ECU, which is electrically connected to a CAN communication module, and a half-bridge drive module is electrically connected to a starter generator motor.

[0017] Optionally, in this embodiment, a voltage regulator is provided between the MCU and the battery, and a voltage divider resistor is provided between the mode selection port of the CAN communication module and the MCU. In this embodiment, the battery refers to the motorcycle's built-in battery, and the voltage regulator serves to stabilize the voltage.

[0018] Optionally in this embodiment, the number of switching transistors is two, with one switching transistor corresponding to the Hall power supply module and the half-bridge drive module.

[0019] Optionally, in this embodiment, the switching transistor can be replaced with a MOSFET.

[0020] like Figure 2As shown, the workflow of this embodiment is as follows: During normal startup, turn the key to turn on the power switch. At this time, the vehicle is powered on. Then, press the start button and squeeze the brake. At this time, the engine speed is <1200rpm, completing the vehicle startup. Subsequently, the vehicle enters the voltage regulation mode, where the engine speed is ≥1300rpm until the vehicle stops and the engine shuts off. However, if the key is turned on but the start button is not pressed and the vehicle remains stationary for a period of time exceeding a preset value, such as 10 minutes, it enters the sleep control mode. In this mode, the vehicle remains dormant until the start button is pressed and the brake is squeezed to start the vehicle, at which point the vehicle exits the sleep control mode.

[0021] The specific implementation is as follows: When the motorcycle key is turned on (power switch closed), if the start button is not pressed and the vehicle is stationary for more than 10 minutes, the MCU (Microcontroller Unit) does not detect any signal change from the Hall sensor. Subsequently, the MCU's sleep control port sends a sleep signal (such as a high-level 5V signal). This sleep signal is input to the bases of switching transistors Q1 and Q2, turning them on. This controls the enable port of the Hall power supply module from high level to ground, thus switching the Hall power supply module from normal mode to sleep mode, at which point power supply to the Hall sensor stops. Simultaneously, after the sleep signal turns on switching transistor Q2, the enable port of the MOS driver chip in the half-bridge driver module changes from high level to ground, switching the half-bridge driver module from normal mode to sleep mode. The sleep signal, after being divided by resistors R3 and R4, is input to the mode selection port of the CAN (Controller Area Network) communication module. At this time, the CAN communication module enters sleep mode, cutting off CAN communication with the ECU (Electronic Control Unit). The Hall effect power supply module, half-bridge drive module, and CAN communication module are all in sleep mode, significantly reducing standby power consumption. When the motorcycle key is turned on and the engine starts normally, the engine drives the starter generator. The MCU detects changes in the Hall effect signal through the Hall sensor (the Hall effect signal is a changing square wave signal during normal vehicle operation). The MCU's sleep control port sends a low-level signal, which turns off switching transistors Q1 and Q2. The enable pin of the Hall effect power supply module is pulled up to a high level (e.g., 5V) by pull-up resistor R1, and the enable pin of the half-bridge drive module is pulled up to a high level (e.g., 5V) by pull-up resistor R2. At this time, the Hall effect power supply module and half-bridge drive module are in normal operating mode. Simultaneously, the low-level signal is transmitted to the mode selection port of the CAN communication module, and the CAN communication module switches to normal operating mode, communicating normally with the ECU.

[0022] In this embodiment, the voltage regulator is a low-dropout linear voltage regulator.

[0023] Using the motorcycle idle start-stop controller with sleep control in this embodiment has the advantage of good energy saving.
