Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before describing the control device and method for starting the vehicle and the vehicle provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first described. The application scenario may include a vehicle provided with an AMT. The vehicle may be an automobile (e.g., a heavy truck), which is not limited to a conventional automobile, a pure electric automobile, or a hybrid automobile, but may be another type of automobile or a non-automobile.
Fig. 1 is a block diagram illustrating a control apparatus for vehicle start according to an exemplary embodiment. As shown in fig. 1, the apparatus 100 includes: the control module 101, the starting relay 102 and the neutral switch 103, the control module 101 is connected with a first end of the starting relay 102, a second end of the starting relay 102 is grounded, a first end of a normally open contact of the starting relay 102 is connected with an ignition switch 200 of a vehicle, a second end of the normally open contact is connected with a first end of the neutral switch 103, and a second end of the neutral switch 103 is connected with a starter 300.
The control module 101 is configured to acquire a current first gear of a transmission of a vehicle, and send an activation signal to the starter relay 102 when the first gear is a neutral gear.
And the starting relay 102 is used for controlling the normally open contact to be closed after receiving the activation signal so as to connect the ignition switch 200 with the neutral switch 103.
And a neutral switch 103 for switching from an open state to a closed state when a shift lever of the vehicle is in a neutral position.
When ignition switch 200 is connected to neutral switch 103 and neutral switch 103 is in the closed state, power is supplied to starter 300 via battery 400 of the vehicle when ignition switch 200 is turned on, so that starter 300 controls the engine start of the vehicle.
For example, when the AMT vehicle is started, the electric energy of battery 400 is converted into mechanical energy by a starting circuit of the vehicle, so that starter 300 starts to operate and drives a crankshaft of the engine to rotate, so as to start the engine. The starting circuit is composed of a battery 400, an ignition switch 200, a starter relay 102 and a starter 300 connected in series. If the gear of the gearbox is in a neutral gear and the gear shifting handle of the vehicle is not in the neutral gear, if a user turns a key of the vehicle to a START gear, the gear shifting handle may send gear information to a TCU (Transmission Control Unit, chinese) of the gearbox because the gear shifting handle is not in the neutral gear, and the TCU switches the gear according to the gear information sent by the gear shifting handle, which may cause the vehicle to suddenly move and cause potential safety hazards.
In order to avoid that when the gear of the gearbox is in neutral and the gear shift handle of the vehicle is not in neutral, the user turns the key of the vehicle to START, which results in false starting of the vehicle, a neutral switch 103 (i.e. the neutral switch 103 is connected in series to the starting circuit) may be arranged between the starting relay 102 and the starter 300, and the neutral switch 103 may monitor the gear of the gear shift handle. When a user controls the vehicle to start, the current first gear of a gearbox of the vehicle is firstly acquired through the control module 101, when the first gear is not in the neutral gear, the starting relay 102 is not activated, a normally open contact of the starting relay 102 is disconnected, and the ignition switch 200 is disconnected from the neutral switch 103. When the first gear is the neutral gear, an activation signal (the activation signal may be a high level signal, for example) is sent to the starting relay 102 through the control module 101, and after receiving the activation signal, the starting relay 102 is activated, a coil of the starting relay 102 is attracted, a normally open contact is closed, and the ignition switch 200 is connected with the neutral switch 103. When the shift lever is not in neutral (for example, in 1 st gear), neutral switch 103 is off, the starting circuit is off, battery 400 cannot supply power to starter 300, and the engine cannot be started. When the shift handle is in neutral, the neutral switch 103 is switched from an off state to an on state, and at this time, the battery 400 can supply power to the starter 300, so that the starter 300 starts to operate, and the starter 300 controls the engine of the vehicle to start. That is, only when both conditions of the ignition switch 200 being connected to the neutral switch 103 and the neutral switch 103 being in the closed state are satisfied (i.e., when the first gear is neutral and the shift lever is in the neutral state), the user turns the key of the vehicle to START (i.e., the ignition switch 200 is closed), and the starter circuit is connected to supply power to the starter motor 300 from the battery 400, thereby starting the engine.
It should be noted that, when the control module 101 cannot obtain the current first gear of the transmission (for example, a line fault occurs), the control module 101 cannot effectively determine the first gear. Therefore, in order to ensure the safety of vehicle starting, the starting relay 102 is a normally open relay, so that the control module 101 cannot control the starter 300 to start when the first gear cannot be obtained, thereby further improving the safety of vehicle starting.
As described above, the control device for vehicle start according to the present disclosure includes: the control module is connected with a first end of the starting relay, a second end of the starting relay is grounded, a first end of a normally open contact of the starting relay is connected with an ignition switch of a vehicle, a second end of the normally open contact is connected with a first end of the neutral switch, a second end of the neutral switch is connected with a starter, the control module is used for acquiring a current first gear of a gearbox of the vehicle and sending an activation signal to the starting relay when the first gear is neutral, the starting relay is used for controlling the normally open contact to be closed after receiving the activation signal so that the ignition switch is connected with the neutral switch, the neutral switch is used for switching from an off state to an on state when a gear shifting handle of the vehicle is in neutral, the ignition switch is connected with the neutral switch, and if the ignition switch is switched on when the neutral switch is in the on state, power is supplied to the starter by a battery of the vehicle such that the starter controls engine starting of the vehicle. According to the control method and the control device, when the gear of the gearbox is in a neutral gear, whether the engine is allowed to be started or not is controlled according to the gear of the gear shifting handle, the vehicle is prevented from being started by mistake, and the safety of vehicle starting is improved.
Optionally, the control module 101 is configured to:
and acquiring a first gear and a vehicle door state of the vehicle, wherein the vehicle door state comprises an unlocking state and a locking state.
When the first gear is neutral and the door state is the locked state, an activation signal is sent to the starter relay 102.
In one scenario, when the vehicle is started, if the door of the vehicle is in the unlocked state, the door may be opened during the starting process of the vehicle, which brings a safety risk to a user in the vehicle, a first gear and the door state of the vehicle may be obtained by the control module 101, and when the first gear is neutral and the door state is in the locked state, an activation signal is sent to the start relay 102 to activate the start relay 102. That is, the starter 300 allows the power-on start only when the control module 101 determines that the three conditions of the first gear being the neutral gear, the door state being the locked state, and the neutral switch 103 being the closed state are satisfied simultaneously, which further improves the safety of the vehicle start.
FIG. 2 is a block diagram illustrating another control apparatus for vehicle launch, according to an exemplary embodiment. As shown in fig. 2, the device 100 further includes a gear switch 104 and a lock-up switch 105, the gear switch 104 is disposed on the transmission, the lock-up switch 105 is disposed on the vehicle door, and the gear switch 104 and the lock-up switch 105 are both connected to the control module 101.
The gear switch 104 is connected with the control module 101 through a hard wire, and the locking switch 105 is connected with the control module 101 through a hard wire.
And the gear switch 104 is configured to acquire a first gear and send a gear signal to the control module 101 according to the first gear, where the gear signal is used to indicate the first gear.
And the locking switch 105 is used for acquiring the state of the vehicle door and sending a locking signal to the control module 101 according to the state of the vehicle door, wherein the locking signal is used for indicating the state of the vehicle door.
In another scenario, the control module 101 may obtain the first gear and the door state through the gear switch 104 and the lock-up switch 105, as shown in fig. 3, the control module 101 may include: an ECU (Electronic Control Unit, chinese), a TCU and a CBCU (central Body Control Unit, chinese), which are connected to the ECU through a CAN (Controller Area Network, chinese) bus or a LIN (Local Interconnect Network, chinese) bus. The gear switch 104 may be hard wired to the TCU and the lock switch 105 may be hard wired to the CBCU.
The range switch 104 may send a range signal to the TCU based on the first range and the TCU sends the range signal to the ECU via the CAN bus or the LIN bus. For example, whether the gear switch 104 is closed may be used as the gear signal, and when the gear of the transmission is neutral, the gear switch 104 is closed, and the TCU receives the gear signal with the gear switch 104 closed (i.e., the gear signal indicates that the first gear is neutral), and transmits the gear signal to the ECU through the CAN bus or the LIN bus. When the gear of the transmission is not neutral (for example, the gear of the transmission is forward), the gear switch 104 is turned off, and the TCU receives a gear signal indicating that the gear switch 104 is turned off (i.e., the gear signal indicates that the first gear is not neutral), and transmits the gear signal to the ECU through the CAN bus or the LIN bus. The lock switch 105 may send a lock signal to the CBCU based on the door state, and the CBCU sends the lock signal to the ECU via the CAN bus or the LIN bus. For example, whether the lock switch 105 is closed may be used as the lock signal, when the door is locked, the lock switch 105 is opened, the CBCU receives the lock signal indicating that the lock switch 105 is opened (i.e., the lock signal indicates that the door is in the locked state), and transmits the lock signal to the ECU through the CAN bus or the LIN bus. When the vehicle door is not locked, the locking switch 105 is closed, the CBCU receives a locking signal indicating that the vehicle door is in an unlocked state from the closed locking switch 105 (i.e., the locking signal indicates that the vehicle door is in an unlocked state), and transmits the locking signal to the ECU through the CAN bus or the LIN bus.
Further, the control module 101 is configured to send an activation signal to the starter relay 102 when the gear signal indicates that the first gear is the neutral gear and the lock signal indicates that the door state is the lock state.
After receiving the gear signal and the locking signal, the control module 101 determines the gear signal and the locking signal through the ECU, and when the gear signal indicates that the first gear is neutral and the locking signal indicates that the door state is the locking state, sends an activation signal to the start relay 102 to activate the start relay 102, so that the coil of the start relay 102 is attracted, and the normally open contact is closed. At this time, the user turns the key of the vehicle to START gear, and if the shift lever is not in neutral, neutral switch 103 is turned off, battery 400 cannot supply power to starter 300, and the engine cannot be started. If the shift handle is in neutral, neutral switch 103 is closed and battery 400 supplies power to starter 300, thereby starting the engine.
It should be noted that, when a problem occurs in the hard-wired connection between the gear switch 104 and the lock switch 105 and the control module 101, or the signals transmitted by the TCU and the CBCU through the bus are not reliable, the ECU may not receive the gear signal and may not perform effective determination. Therefore, in order to ensure the safety of the vehicle starting, the starter relay 102 is a normally open relay, so that the starter 300 cannot be controlled to start when the ECU does not receive the shift signal indicating that the first shift is the neutral, thereby further improving the safety of the vehicle starting.
