Example 1
The embodiment provides a method for switching an operation mode of an automatic transmission automobile, which can be applied to a control system of a vehicle, and as shown in fig. 1, the method comprises the following steps:
s101: and setting vehicle operation parameters in the motion mode, wherein the vehicle operation parameters comprise an initial gear-up speed corresponding to the gear change node during gear-up operation, and the initial gear-up speed is greater than a reference initial gear-up speed corresponding to the gear change node during the same gear-up operation in the common mode. Specifically, the upshift initial speed corresponding to each gear shift node may be defined directly in the system by means of a preset instruction code.
S102: and responding to a mode switching instruction, and switching the vehicle running mode from the normal mode to the sport mode or switching the vehicle running mode from the sport mode to the normal mode.
Further, in the above aspect, the upshift initial speed is 1.05 to 1.25 times, and preferably 1.2 times, an upshift reference initial speed corresponding to a gear shift node in the same upshift operation in the normal mode. Referring to fig. 2, the upshift strategy in the automatic transmission vehicle motion mode of the present embodiment is shown from left to right, and the upshift strategy is to adjust the gear according to the accelerator opening and the vehicle speed, such as in Normal mode, upshift from 1 gear to 2 gear when the vehicle speed reaches 15kph, and upshift from 1 gear to 2 gear when the vehicle speed reaches 18 kph. By increasing the initial speed from 1 gear upshift to 2 gear upshift, the time for the vehicle to upshift from 1 gear to 2 gear can be shortened, and in the above scheme, after the vehicle is switched to the Sport mode, as shown in the figure, when the gear is upshifted 1 → 2, the speed node of the gear change in the Normal mode is lower than the speed node of the gear change in the Sport mode. Therefore, the response speed of the Sport mode during the upshift is significantly greater than the upshift response speed of the normal mode, referring to fig. 3, the upshift rotation speed in the Sport mode is basically delayed by 600rpm to 1000rpm, so that the shift timing of the vehicle can be delayed, the response time of the vehicle during the acceleration can be shortened for the vehicle, and a user can experience that the vehicle has a higher acceleration response in the Sport mode. The schematic diagram of the upshift rotation speed is calculated by considering the total speed ratio of the transmission system of the whole vehicle according to the upshift vehicle speed in fig. 2, specifically, the vehicle speed at the wheel side is inversely calculated to the engine rotation speed through the rolling radius of the tire, the final reduction ratio, the speed ratio of the gearbox, the speed ratio of the hydraulic torque converter and the like, variables in the whole process are the vehicle speed and the speed ratio of the gearbox, and the upshift vehicle speed is higher, the speed ratio of the gearbox is larger, and the corresponding engine rotation speed is higher in the 'Sport' mode.
Preferably, the vehicle operation parameter includes a downshift initial speed corresponding to the shift change node during a downshift operation, wherein: and the initial gear-down speed is smaller than the reference initial gear-down speed corresponding to the gear change node during the same gear-down operation in the common mode. Further, the downshift initial speed is 0.80-0.95 times, preferably 0.9 times, of a downshift reference initial speed corresponding to the shift change node in the same downshift operation in the normal mode. Referring also to fig. 2, the upshift strategy in the automatic transmission type Sport mode of the present embodiment is shown from right to left, and the upshift strategy is to adjust the gear according to the accelerator opening and the vehicle speed, such as in Normal mode, the downshift from 2 to 1 is performed when the vehicle speed reaches 16kph, and in Sport mode, the downshift from 2 to 1 is performed when the vehicle speed reaches 13 kph. By increasing the initial speed from the 2-gear downshift to the 1-gear downshift, the time of the vehicle from the 2-gear downshift to the 1-gear downshift can be shortened. Therefore, the response speed of the vehicle in the sport mode during downshift is obviously greater than the downshift response speed in the normal mode, so that the downshift timing of the vehicle can be delayed, the response time of the vehicle during deceleration can be shortened for the vehicle, and the vehicle has higher downshift response.
Further, the vehicle operating parameters further include a highest gear; wherein the highest gear is one gear lower than the highest gear in the normal mode. Similarly, referring to fig. 2, the Normal mode includes an upshift from 5 to 6, while the Sport mode does not include an upshift from 5 to 6, that is, an upshift in the high gear is suppressed (the 6-gear automatic transmission controls the highest gear to 5 by suppressing the high gear).
To sum up, the simple description of the shift process under the Sport mode in this scheme is: in the process of slowly accelerating the vehicle, along with the increase of the opening degree of the accelerator and the speed of the vehicle, when the working point passes through the upshift line from left to right in fig. 2, the transmission controller controls the vehicle to perform upshift operation, and similarly, when the working point passes through the downshift line from right to left, the vehicle performs downshift operation. Compared with Normal, the speed-up point of the Sport mode is delayed obviously, the speed is shifted down more easily, the 6-gear of the gearbox is restrained, and the vehicle is enabled to work in the gear with a large speed ratio as much as possible.
Further, in the above method, the vehicle operation parameter further includes a throttle opening corresponding to an accelerator pedal opening; the throttle opening is larger than a reference throttle opening corresponding to the same accelerator pedal opening in the normal mode. Wherein the throttle opening is 1.1-1.3 times, preferably 1.2 times of the reference throttle opening corresponding to the same accelerator pedal opening in the normal mode. Referring to fig. 4 a-4 d, vehicle speed curves in Normal mode and Sport mode are respectively corresponding to throttle opening of 10%, 30%, 50% and 70%, and throttle opening is in direct proportion to throttle opening, a throttle valve of a vehicle in the prior art is replaced by an electronic throttle valve, an electronic throttle valve control system is equipped with a throttle opening sensor for monitoring throttle opening (%), but in the present scheme, under the same throttle opening, after the vehicle activates Sport mode, the electronic throttle opening changes into a more aggressive state, even if the throttle opening is obviously increased and the throttle increasing speed is obviously increased, that is, the degree and the rate of throttle adjustment are both increased, thereby rapidly increasing the power torque output of the engine, improving the acceleration response of the vehicle, and rapidly increasing the output power of the engine, a more aggressive acceleration than in the normal mode can be obtained.
Further preferably, in the above aspect, the vehicle operation parameter further includes a resistance coefficient of a steering wheel, wherein the resistance coefficient of the steering wheel is greater than a reference resistance coefficient of the steering wheel in the normal mode. That is, after the Sport mode is activated, the force sense of the steering gear CAN be adjusted through the CAN bus and the EBCM body control module, and the steering hand sense of the steering wheel is increased to improve the direction control of the driver during violent driving to a certain extent. In the scheme, the adjustment of the steering gear force sense is considered, the inventor tests the 'Sport' modes of a large number of product vehicles in long-term vehicle development, integrates the research of a large number of user experience degrees, and provides a radical movement mode which can carry out certain adjustment on the steering force sense, so that the steering force sense is obviously different from a common mode in the sense of touch for a driver.
Preferably, as shown in fig. 5, in the above solution, when the vehicle is switched to the sport mode, the following steps may be further included:
s103: and sending a motion state signal to a vehicle body stabilizing system of the vehicle so that the vehicle body stabilizing system releases the limitation on the driving force during operation. In the Sport mode, auxiliary systems such as an EBCM (electronic brake control module) for controlling traction control TCS, a vehicle body stability control system ESC and a brake anti-lock braking system ABS are more biased to the mobility, so that drivers can obtain different driving pleasures. Specifically, after the vehicle enters the sport mode, the vehicle should be heavier in controllability, the general mode may be more comfortable, and the sport mode should be more controllable, so as to give the user a driving feeling in the real sport mode. If the driving torque of the vehicle can not be limited by the traction control TCS system, the output torque of the engine can be completely transmitted to the driving wheels; by adjusting the braking force and braking torque distribution of auxiliary systems such as an ESC (stability control system) and an ABS (anti-lock braking system), the active intervention of an EBCM (electronic brake control module) on the controllability of the vehicle is reduced, and a driver can feel full driving pleasure.
S104: sending a motion state signal to a suspension control system of the vehicle to cause the suspension control system to increase a damping value of a shock absorber in the suspension. For some vehicle models with emphasis on mobility, a suspension system such as a variable damping shock absorber can be additionally provided, so that the damping of the shock absorber can be increased in a Sport mode, the suspension system is hardened, the support performance on a vehicle body is stronger, and the vehicle body posture is easier to maintain during turning.
S105, sending a motion state signal to a control end of the variable back pressure exhaust valve to enable the variable back pressure exhaust valve to be adjusted to an opening state; the variable back pressure exhaust valve is arranged in an exhaust pipe of the vehicle. The variable back pressure exhaust valve is installed at the tail end of the vehicle exhaust, and the principle of the variable back pressure exhaust valve is that the variable valve is arranged in the exhaust pipe, when the valve is closed, the exhaust airflow is discharged from a position with a smaller pipe diameter or a single pipeline, and the back pressure in the exhaust pipe is kept; when the valve is opened, the exhausted waste gas is directly exhausted through the pipe diameter position or the double pipelines, so that the waste gas has more channels and outlets for ventilation, the back pressure in the exhaust pipe is further reduced, and the continuity of the power can be more ideal. On the one hand, the exhaust can be smoother, and the power output under high rotating speed is facilitated, on the other hand, the exhaust sound wave can be more violent, and the 'movement property' of the vehicle is improved in the sense of hearing.
And S106, sending the motion state signal to an instrument panel control system to reduce the color tone of the background color of the instrument panel and simultaneously displaying prompt information for entering the motion mode on the instrument panel. When the vehicle enters the Sport Mode, the electronic control module controls the instrument panel to display words such as 'Sport Mode' and the like, and prompts a driver that the vehicle is in the Sport Mode at present and please drive cautiously. Meanwhile, the background color of the instrument panel can be controlled to be changed from a bright color to a dark color, so that the driver can be visually provided with a sporty feeling, and the driver can be reminded that the vehicle is in a Sport mode at present.
