[0059] The following is combined with Figure 1-8 This application is described in further detail.

[0060] Embodiment 1 of the present application discloses a new energy vehicle gear lever. Figure 1 and Figure 2 The gear lever of the new energy vehicle includes a gear lever 1 for swinging and shifting gears, and an unlocking button 23 and a parking button 22 are installed on the gear lever 1. The unlocking button 23 is installed on the side position of the upper end of the gear lever 1, and the parking button 22 is installed on the upper end of the gear lever 1, and the unlocking button 23 and the parking button 22 are both used for users to press. A switching switch 2 and a plurality of partition plates 21 are installed in the gear lever 1, and different functional modules 3 are installed between adjacent partition plates 21, and each functional module 3 is a separate modular circuit board for easy maintenance and replacement. The switching switch 2 is installed on the rotating shaft of the gear lever 1. The switching switch 2 can be, for example, a toggle switch or a multi-way selector or other switches with a switching function to connect the new energy vehicle system with different functional modules 3. A locking module 11 for locking the rotation of the gear lever 1 is also installed on the rotating shaft of the gear lever 1. The unlocking button 23 is connected to the locking module 11, and can be mechanically connected through a mechanical structure, or can be electrically connected through a circuit structure. The unlocking button 23 is used to control the locking module 11 to lock the rotating shaft of the gear lever 1 or unlock it.

[0061] Reference Figure 3 The functional module 3 includes a P gear module 31 for parking, an R gear module 32 for reversing, an N gear module 33 for neutral gear and a D gear module 34 for moving forward. The functional module 3 is electrically connected to the input end of the switching switch 2, that is, the switching switch 2 has three input ends and one output end. The three input ends of the switching switch 2 are electrically connected to the R gear module 32, the N gear module 33 and the D gear module 34 one by one. The output end of the switching switch 2 is electrically connected to the new energy vehicle system. The output end of the switching switch 2 is electrically connected to one of the input ends by toggling the gear lever 1, and the parking button 22 is electrically connected to the P gear module 31, and the P gear module 31 is directly electrically connected to the new energy vehicle system.

[0062] The implementation principle of the gear lever of a new energy vehicle in the embodiment of the present application is as follows: when the gear lever 1 fails, the gear lever 1 can be directly disassembled, and the failed functional module 3 can be found and replaced with a new functional module 3.

[0063] Embodiment 2:

[0064] Different from Example 1, Figure 4, Embodiment 2 of the present application discloses that the gear lever of a new energy vehicle includes an angle detection module 4, a reset module 41 and an unlocking module 42. The angle detection module 4 can adopt an angle sensor, a capacitive encoder or other sensors with rotation detection, detect and obtain angle detection data and output it. The reset module 41 can adopt a motor, and the rotating shaft of the reset module 41 is fixedly connected to the rotating shaft of the gear lever 1, and receives the control of the new energy vehicle system. The unlocking module 42 can adopt magnetic induction to control the locking module 11. For example, the locking module 11 adopts a tripping mechanism similar to that in a circuit breaker. When the locking module 11 is inserted into the rotating shaft of the gear lever 1 to achieve mechanical locking, the unlocking module 42 can give the locking module 11 magnetism through electromagnetic induction, so that the locking module 11 withdraws from the rotating shaft of the gear lever 1 after being attracted by the permanent magnet. The unlocking module 42 and the locking module 11 can also adopt other structures, so that the unlocking module 42 can finally accept the control of the new energy vehicle system to release the locking module 11 from the rotating shaft of the gear lever 1. The new energy vehicle system includes at least a processor and a database. The database stores various threshold data, including angle judgment threshold, gear threshold, fault threshold and other threshold data. The processor receives the angle detection data, and then calls the corresponding threshold data from the database, calculates and processes the data, and then outputs it, and controls the reset module 41 and the unlocking module 42.

[0065] The processor may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software. After the meter has a processor, people can freely control the metering instrument through programming to make it run according to people's wishes. The processor can control local measurement transmission, remote measurement transmission, remote communication, etc. through internal protocols. Internal protocols refer to all protocols that achieve mutual communication or links within the same metering instrument or the same system, including: human-computer interaction protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, internal bus (I-Bus) protocols, etc. Part or all of the protocols. With the development of integrated circuit technology, some protocols that belong to the external bus (E-Bus) protocol are also classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0066] Embodiment 2 of the present application discloses a method for controlling a gear lever of a new energy vehicle. Figure 5 , the control method of the gear lever of a new energy vehicle comprises the following steps:

[0067] S1. Obtaining angle detection data and vehicle status data;

[0068] S11, determining the gear lever state data by using the angle detection data and a preset angle judgment threshold;

[0069] S12, determining fault status data according to vehicle status data, gear lever status data and a preset gear position threshold;

[0070] S13, determining a fault detection signal through the fault state data and a preset fault threshold;

[0071] S14. Determine the fault cause data through the fault detection signal, fault status data and fault threshold and output it.

[0072] Detailed: The angle detection data is obtained by detecting the rotation angle of the gear lever 1 through the angle sensor. The vehicle status data is the data of the current state of the vehicle, such as the forward state or the reverse state or the motor is disconnected from the battery and is in the neutral state. The angle judgment threshold is the angle of the gear lever 1 controlling the new energy vehicle to be in the corresponding gear. The angle judgment threshold is set to (0°±5°, R gear), (15°±5°, N gear), (30°±5°, D gear). If the angle detection data is 2°, it is judged that the gear lever 1 is in the R gear. At this time, the new energy vehicle should theoretically be in the reverse state, and the current direction to the motor should be in the reverse direction. This current direction is the fault state data, that is, the corresponding gear state. What state should the new energy vehicle be in, and then from the vehicle status data The current state of the vehicle is obtained. If the vehicle is also in the reversing state and the current direction of the motor is correct, it means that there is no fault. If the vehicle state data indicates forward movement, that is, the current direction of the motor is wrong, then the fault state data indicating the fault is obtained, and then this is compared with the fault threshold to obtain a fault detection signal for starting detection and output it. At this time, the new energy vehicle is controlled to brake and stop, and then other functional modules 3 are triggered in sequence according to the specified order. Steps S1-S12 are repeated, and corresponding fault state data are obtained each time, and compared with the fault threshold one by one to obtain the final fault cause data. If other functional modules 3 are normal, the fault cause data indicating the fault of the reversing functional module 3 is obtained and output to the user for viewing.

[0073] Reference Figure 6 , further comprising the following steps:

[0074] S2, obtaining driving speed data, driving status data and time data;

[0075] S21, determining abnormal shifting data through driving speed data, driving state data, gear lever state data and gear position threshold;

[0076] S22, determining safety difference data according to a preset safety threshold, driving speed data and gear lever state data;

[0077] S23, determining and outputting a reset signal based on the abnormal gear shifting data, the safety difference data, the driving status data and a preset reset threshold value.

[0078] Detailed: The driving speed data is the current speed of the vehicle, including forward speed, reverse speed, neutral pulley speed, etc. The driving status data is the driver's status of the new energy vehicle, such as half-stepping the accelerator, full stepping the accelerator, half-stepping the brake, full stepping the brake, etc. If the gear lever status data indicates that the gear lever 1 is in the R gear, combined with the gear position threshold, it is obtained that the new energy vehicle should be in the reverse state at this time. However, if the driving speed data is 50km / h and the driving status data is forward, it means that the vehicle is in the process of fast forwarding at this time, then the abnormal shift abnormality data indicating the abnormality is output. The safety threshold is set to 10km / h, indicating that when the reverse gear is switched, the vehicle speed should be above 10km / h. It is safe only when the gear shifting speed is 15km / h, so the safety difference data of 40km / h can be obtained, indicating that the vehicle speed at this time is 40km / h more than the safe speed. Assuming the reset threshold is 50%, it means that when the gear shifting abnormality data indicates the gear shifting abnormality, the safety difference data can only exceed the safety threshold by an additional 50% at most, that is, the vehicle speed should be 15km / h, and the safety difference data should not exceed 5km / h, while 40km / h is far more than 5km / h, and the driving status data indicates that the driver is still stepping on the accelerator and has no intention of slowing down to the safe interval for reversing, then a reset signal indicating that the gear lever 1 is swung incorrectly is obtained, and the reset signal controls the gear lever 1 to reset to the D gear through the reset module 41.

[0079] Reference Figure 7 , after step S23, the following steps are also included:

[0080] S3, determining reset consistency data through the reset signal, the abnormal shift data and the driving state data;

[0081] S31, determining a confirmation signal by resetting consistency data, time data and a preset confirmation threshold, and outputting the confirmation signal instead of the reset signal;

[0082] S32, or, determining emergency shift data through abnormal shift data, safety difference data, driving state data and a preset emergency threshold;

[0083] S33, determining a confirmation signal through the emergency shift data and outputting it instead of a reset signal.

[0084] In detail: let the determination threshold be (2, 1s), 2 means 2 times in a row, 2s means the interval between two consecutive reset signals does not exceed 1s. After outputting multiple reset signals, first determine whether the adjacent reset signals are reset signals caused by the same abnormal shift data and the same driving state data. If the determination is yes, and the time data corresponding to the two adjacent reset signals are very close, for example, they occur continuously within 1s, it means that the gear lever 1 is not operated by mistake, but may be operated consciously by the driver, so as to output a confirmation signal so that the reset module 41 will not reset the gear lever 1; if the abnormal shift data indicates that the gear lever 1 is switched to the R gear, and the safety difference The data is 40km / h, but the driving status data is that the accelerator is pressed to the bottom in a short time and the brake is pressed to the bottom in a short time. The emergency threshold is set to (the accelerator is pressed to the bottom in a short time, switching to R gear, emergency reverse / emergency brake), which means that an emergency situation occurs at this time. For example, the vehicle in front suddenly rolls over, resulting in a shorter distance, or the vehicle itself is fully loaded, resulting in a longer braking distance. The driver is worried that the brakes will be pressed to the bottom and he will not be able to brake at a safe distance, so he hurriedly shifts into reverse gear and presses the accelerator to the bottom, thereby realizing the reverse rotation of the motor, accelerating the deceleration of the wheels, and further reducing the braking distance. At this time, a confirmation signal will also be output to the reset module 41 to prevent the reset module 41 from resetting the gear lever 1.

[0085] Reference Figure 8 , further comprising the following steps:

[0086] S4, confirming that the signal includes an emergency shift signal, and determining the direction change data through the driving state data and the emergency threshold;

[0087] S41, determining acceleration data through driving speed data and time data;

[0088] S42, determining danger data through acceleration data, driving state data and a preset deceleration threshold;

[0089] S42, determining emergency reversing data through the hazard data, acceleration data, driving speed data, reversing data and a preset comprehensive coefficient;

[0090] S43, determining an emergency shift signal based on the emergency reversing data and a preset reversing threshold and outputting the signal.

[0091] Detailed: If the driving status data is that the accelerator and brake are pressed to the bottom and are within the emergency threshold, the corresponding reversing data is obtained. If the time data is 1s and the driving speed data is 100km / h, the time data is 2s and the driving speed data is 80km / h, the time data is 3s and the driving speed data is 60km / h, then the acceleration data can be obtained as -5.6m / s 2 , and combined with the driving status data, the deceleration threshold is set to (no load, -8m / s 2, x), (full load, -5m / s 2 , y), represents the maximum braking speed of the new energy vehicle under no-load and full-load conditions respectively, and the driving status data indicates that the brake is stepped on to the bottom, -5.6 is close to -5, indicating that the vehicle is close to full load, x and y are coefficients for calculating the degree of danger, at this time the degree of danger is high, and the corresponding danger data is obtained, and then the danger data, acceleration data, driving speed data and reversing data are combined with the comprehensive coefficient, assuming the comprehensive coefficient is (a, b, c, d), the simplest algorithm is emergency reversing data = a*danger data + b*acceleration data + c*driving speed data + d*reversing data, at this time due to the full load acceleration data is low, but by the higher danger data to compensate, and by comparing with the reversing threshold, if the emergency reversing data exceeds the range of the reversing threshold, it means that this is an emergency reversing rather than a false touch.

[0092] Embodiment 2 of the present application discloses a computer-readable storage medium. The computer-readable storage medium stores a computer program that can be loaded by a processor and execute a method for controlling a gear lever of a new energy vehicle.

[0093] Computer-readable storage media include, for example, various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

[0094] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
