Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.
The embodiment of the application provides a gear processing and sending method of an electronic gear shifter, which can solve the problems that the electronic gear shifter in the related art is easy to be triggered mistakenly and an instrument flashes when the gear shifting operation is carried out.
Referring to fig. 1, the specific steps of the present method for processing and transmitting gears mainly include:
acquiring a position signal of a stop lever and the stay time of the stop lever at a corresponding position, and determining a gear request of the stop lever according to the position signal;
if the gear request of the gear lever is a first-order gear request, judging whether the retention time of the gear lever corresponding to the first-order gear is not less than a first preset time, and if so, sending the corresponding first-order gear request;
if the gear request of the gear lever is a second-order gear request, whether the residence time of the gear lever corresponding to the first-order gear is shorter than a first preset time or not is judged, if yes, whether the residence time of the gear lever corresponding to the second-order gear is shorter than a second preset time or not is judged, and if yes, the corresponding second-order gear request is sent.
Specifically, the gear processing and transmitting method mainly aims at monostable five-point electronic gear shifting, the gear has five positions, the middle position is a steady-state gear, the gear lever can move along an upper direction and a lower direction respectively when in the steady-state gear, each direction can move twice continuously, the two gears above the gear lever are a first-order gear and a second-order gear respectively, the two gears below the gear lever are a first-order gear and a second-order gear respectively, the first-order gear comprises the first-order gear and the second-order gear, and the second-order gear comprises the first-order gear and the second-order gear. According to the gear processing and sending method, a gear request of the gear lever is firstly determined according to the acquired position signal, the gear request is not sent immediately after the gear request is determined, the dwell time of the gear lever corresponding to the first-order gear and the first preset time are compared according to the fact that the gear request is specifically the first-order gear request or the second-order gear request, if the gear request is the second-order gear request, the dwell time of the gear lever corresponding to the second-order gear and the second preset time need to be continuously compared subsequently, and therefore whether the corresponding first-order gear request or the corresponding second-order gear request is sent or not is determined. Compared with the previous processing and sending method, the gear processing and sending method can effectively solve the unexpected and false triggering of the gear request, for example, when a driver or a passenger in a copilot takes things or performs other actions, the gear lever is carelessly driven to move, so that the gear processing and sending method can filter some unexpected gear requests, and the safe driving of the driver is ensured; in addition, when the gear is shifted to the second-order gear, the first-order gear is inevitably required to be passed through, in the previous processing and sending method, when the gear lever passes through the corresponding gear position, the corresponding gear request can be generated and sent, and therefore the N-gear flashover is often caused.
Further, referring to fig. 2, the specific step of, if the gear request of the gear lever is a first-order gear request, further includes: judge the pin is corresponding whether the dwell time of first-order fender position is less than first default time, if, then judge further the pin is corresponding whether the dwell time of first-order fender position is not less than third default time, if, then judge again further the position signal of pin is for following the correspondence first-order fender position is replied to the steady state fender position, judges promptly now whether the position of pin is in the steady state fender position, and is from corresponding first-order fender position removes to the steady state fender position, if, then send the correspondence first-order fender position request.
Specifically, though it is said that the situation of the unexpected trigger-miss gear request can be well avoided by the logic judgment between the first preset time and the stay time corresponding to the first-order gear of the gear lever, and the logic judgment between the second preset time and the stay time corresponding to the second-order gear of the gear lever, for some drivers with long driving ages, because the whole logic judgment time is long, a problem of reaction delay may be caused in the normal driving process, and the driving experience of the driver is also reduced. Therefore, after the conditions described above are met, the first-order gear request can be sent immediately when the gear lever is moved from the first-order gear to the steady-state gear, the first-order gear request does not need to wait for the first preset time, the smoothness of operation is guaranteed, and the driving requirements of different drivers are met.
Further, referring to fig. 3, the step of the gear processing transmission method further includes: if the position signal of the gear lever is monitored to be directly switched from the corresponding first-order gear to the corresponding second-order gear on the same side, whether the stay time of the gear lever corresponding to the first-order gear is longer than the first preset time or not is judged, and if yes, a prompt signal for replying the steady-state gear is sent.
Specifically, if it is monitored that the position signal of the shift lever is directly switched from the corresponding first-order gear to the corresponding second-order gear on the same side, it is indicated that the shift lever does not pass through the steady-state gear, and therefore once the shift lever passes through the steady-state gear, two situations exist, one is that the first-order gear request is sent immediately after the condition for quick sending is met, and the other is that the condition for quick sending is not met, the steady-state position is similar to zero clearing of the previous position signal, and a new gear operation is performed from the steady-state position again. Therefore, when the stop time of the gear lever corresponding to the first-order gear is judged to be longer than the first preset time, a steady-state gear return prompt signal is sent immediately, and the steady-state gear return prompt signal is displayed on an instrument board generally or can be obtained by a driver in time through a voice prompt and other modes which are convenient for the driver to obtain so as to perform the next operation.
Further, referring to fig. 3, the step of the gear processing transmission method further includes: if the position signal of the stop lever is monitored to be directly switched from the corresponding second-order gear to the corresponding first-order gear on the same side, whether the stay time of the stop lever corresponding to the second-order gear is longer than fourth preset time or not is judged, if yes, a prompt signal for replying the steady-state gear is sent, and if not, an invalid operation prompt is sent. Similarly, if the stop time of the gear lever in the second-order gear is too long, the gear lever must be returned to the steady-state position before a new gear operation can be performed, and the prompt signal for returning to the steady-state gear is also sent at this time.
Further, the first preset time specifically includes a bar position confirmation time and a delay sending time, and the bar position confirmation time has the same value as the third preset time. Specifically, if the gear request of the gear lever is determined as the first-order gear request, and when it is determined that the stay time of the gear lever corresponding to the first-order gear is shorter than the third preset time, that is, the stay time is shorter than the gear position confirmation time, in this case, since it is not time to confirm the corresponding gear request according to the position signal, the gear request is unchanged, and the position change of the gear lever in this case is that the gear lever is moved from the steady-state gear to the first-order gear and then quickly returned to the steady-state gear. Similarly, when the stop lever is judged to be in correspondence to the second-order gear, the second preset time is shorter than the second preset time, when the stop lever is monitored to be finally reset to the steady-state position, the same gear request is unchanged, if the stop lever is monitored to be returned to the first-order gear on the same side from the corresponding second-order gear and stopped, the invalid operation prompt is sent, and the stop lever also needs to return to the steady-state position firstly, and in such a case, no matter whether the stop lever is corresponding to the first-order gear, the stop lever stays for a time longer than or shorter than the third preset time, the stop lever can be used as long as the stop lever is not longer than the first preset time. Most of the two conditions are caused by false touch, and in a few conditions, the driver immediately resets after operating during gear shifting and wants to perform new gear operation.
Specifically, if the gear request of the gear lever is a second-order gear request, the gear lever is judged to correspond to the first-order gear, the residence time of the first-order gear is shorter than the third preset time, and the gear lever is judged to correspond to the second-order gear, the residence time of the second-order gear is not shorter than the second preset time, and then the corresponding second-order gear request is sent.
Further, referring to fig. 4, the specific step of determining the gear request of the gear lever according to the position signal includes: if the position signal of the stop lever located at the last position is the steady-state gear or the first-order gear, and the acquired position signal does not include the second-order gear, determining that the gear request of the stop lever is the first-order gear request, and if the acquired position signal of the stop lever includes the second-order gear, determining that the gear request of the stop lever is the second-order gear request; generally, the state of a brake pedal switch of an automobile in a preset time period needs to be acquired, the on-off state of a gear shifting unlocking button on the gear lever needs to be acquired, and the on-off state of the brake pedal switch and the on-off state of the gear shifting unlocking button are combined to determine which type of gear request the first-order gear and the second-order gear specifically belong to.
Specifically, the vehicle specifically comprises a gear P, a gear N, a gear D and a gear R, wherein the gear P is a parking gear, the gear N is a neutral gear, the gear D is a reverse gear, the gear R is a forward gear, the first-order gear is defined as up, the second-order gear is defined as up, the steady-state gear is defined as center, the next-order gear is defined as down, and the second-order gear is defined as down. There are several general gear changes as follows:
when other gears are switched from the P gear, the first gear is to press a gear-shifting unlocking button while stepping on a brake pedal to push the gear lever from a center to an up or down position, and the GSM sends a gear request for switching to the N gear; the second mode is that when a brake pedal is stepped on and a gear shifting unlocking key is pressed, the gear lever is pushed from the center to the up position, and a GSM (global system for mobile communications) sends a gear shifting request for shifting to the R gear; and the third mode is that the brake pedal is stepped on, a gear shifting unlocking button is pressed at the same time, the gear lever is pushed to a down position from a center, and the GSM sends a gear shifting request for shifting to the D gear. When other gears are switched from the R gear, the first is to push the gear lever from the center to the up or up up position, and the GSM sends out a gear request of the R gear; the second is to step on a brake pedal and push the gear lever from the center to the down position, and the GSM sends a gear request for switching to the N gear; and the third is to step on the brake pedal and push the gear lever from the center to the down position, and the GSM sends a gear request for switching to the D gear. When other gears are switched from the N gear, the first gear is to step on a brake pedal and press a handle unlocking key to push a gear lever from a center to an up or up position, and the GSM sends out a gear R switching request; the second is to step on the brake pedal and push the gear lever from center to down or down position, and the GSM will send a gear request to shift to D gear. When other gears are switched from the D gear, the first gear is that a gear-shifting unlocking button is pressed while a brake pedal is stepped, the gear lever is pushed from a center to an up up position, and a GSM (global system for mobile communications) sends a gear request for switching to the R gear; the second is to step on the brake pedal and push the gear lever from the center to the up position, and the GSM sends a gear request for switching to the N gear; third, to push the lever from center to down position, GSM will send a gear request to shift to D.
Further, the value ranges of the stop lever position confirmation time and the third preset time are both 80 to 120ms, the value range of the second preset time is also 80 to 120ms, the value range of the delay transmission time is 450 to 550ms, and the value range of the fourth preset time is 280 to 320ms.
The gear processing and sending method can effectively solve the gear request which is not expected to be triggered by mistake, can also avoid the problem that the N gear jumps when the instrument and the gear lever switch partial gears, and reduces the driving experience of a driver, and can well meet the requirements of a novice driver or a driver with more experience, thereby ensuring good experience and safety in the driving process.
