Background
The invention relates to the field of vehicle control, in particular to a rocker type electronic gear shifter and a gear switching control method.
A gear shift device is a device that performs gear shifting on a vehicle. At present, 3 gears on an automobile are selected, the first gear is a conventional manual gear shifter, the gear shifter is connected with a mechanical shifting fork to drive a gear of a gearbox to move, final gear switching is realized, and the gear can be manually and freely switched between 5 gears or 6 gears. The second type is a gear shifter of an automatic transmission, generally only four gears P \ R \ N \ D are reserved, and manual selection is also performed, but in a D gear state, a transmission control unit automatically performs switching of a forward gear speed ratio according to different rotating speeds and torque requirements. The third type is a complete electronic gear shifter, no clear gear mark exists, no mechanical connection exists between the gear shifter and the gearbox, gear signal transmission is carried out in an electric signal mode, when the gear is shifted, a driver dials the gear shifter, a gear shifter control unit receives and analyzes the gear intention of the driver, and the gear signal is sent to the gearbox, so that gear shifting is achieved. Compared with the traditional gear shifter with mechanical connection, the electronic gear shifter is small in size, saves space, and meanwhile eliminates physical damage to mechanical parts caused by misoperation of a driver.
Electronic shifters mostly use knobs or longitudinally sliding shift levers to shift gears. The knob type gear shifting rod is easy to confuse gears during gear shifting, the operation accuracy is not high, and the gears are easy to misplace; the longitudinal gear shifting rod keeps the appearance of the traditional gear shifting rod, has high operability and accuracy, but occupies larger space.
The rocker-type electronic gear shifter has the advantages of being compatible with high gear shifting operability, small in occupied space and reliable in gear shifting.
The specification of chinese invention patent CN107575565B discloses a control method of an electronic shift system, which comprehensively adjusts a transmission according to a shift request sent by a shifter control unit GSM, whether a position sensor of an actuator is faulty, a vehicle speed, and whether the transmission is in a limphome mode; when the actual gear of the gear shifting shaft is the same as the gear requested by the shifter control unit GSM, the shifter control unit GSM controls a gear indicator lamp which is the same as the requested gear to be normally on, otherwise, the shifter control unit GSM controls a gear indicator lamp which is the same as the requested gear to flash; the combination meter displays the actual gear of the transmission. The electronic gear shifting function is realized by cooperatively controlling the gear shifter control unit, the automatic transmission control unit and the actuator control unit, and the invention can ensure that the whole vehicle is in a reasonable gear and ensure the driving safety under the condition that a single or a plurality of control units have faults; but the direction of movement of its shifter is not explicitly described and the shift logic is unclear.
The specification of chinese invention patent CN106090203B discloses an electronic gear control system, which includes: an electronic gear shifter and a vehicle control unit; the electronic gear shifter executes gear shifting operation of a user, acquires a first target gear corresponding to the gear shifting operation, and returns to a default initial position after the gear shifting operation is completed; the vehicle control unit acquires current state information of a vehicle, when the state information is matched with the first target gear, the actual gear to be executed by the vehicle is determined to be the first target gear, and the actually executed first target gear is sent to the electronic gear shifter to be displayed; and when the state information is not matched with the first target gear, determining a second target gear which is actually executed by the current vehicle according to the state information and the first target gear, and sending the second target gear which is actually executed to the electronic gear shifter for displaying. The resettable electronic gear shifter is adopted, the actual gear to be executed is judged through the vehicle controller, the problem that the gear of a handle of the electronic gear shifter is different from the system gear is solved, but the movement direction of a gear shifting handle is not described, and obviously, the general electronic gear shifter is in the front and back directions and is not suitable for a rocker gear shifter capable of moving left and back
