Embodiment Construction
[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0048] An embodiment of the present invention provides a parking control method for an automatic transmission matching an electronic shifter. The parking control method can be realized based on a parking control system for an automatic transmission matching an electronic shifter. The parking control method is applicable to For vehicles parked on ramps. figure 1 It is a schematic structural diagram of an automatic transmission parking control system provided by an embodiment of the present invention, figure 2 It ...

The invention discloses an automatic transmission parking control method and system matched with an electronic gear shifter and a vehicle. The automatic transmission parking control method matched with the electronic gear shifter comprises an electronic gear shifter control unit and a torque release label for detecting a transmission control unit. If the torque release label shows that the torqueis not released, the electronic gear shifter control unit detects the slope of the vehicle. If the slope of the vehicle shows that the vehicle is in a ramp parking work condition, the electronic gearshifter control unit detects a vehicle parking label of a vehicle body stabilization system. If the vehicle parking label shows that electronic parking enabling happens, the electronic gear shifter control unit controls a transmission gear executer to rotate to the gear N, and the state lasts for a first preset time. The electronic gear shifter control unit controls the transmission gear executerto rotate to the gear P, and parking is completed. On the basis of meeting the requirement that the vehicle is parked on a ramp, the problem of impacting of the gear P of a transmission can be solved,overall vehicle parking safety is improved, and the comfort degree of the overall vehicle can be improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular to a parking control method and system for an automatic transmission matched with an electronic shifter, and a vehicle. Background technique [0002] When the transmission of the vehicle is in the D or R gear, the driver steps on the brake pedal, puts in the P gear to park, and the engine torque is transmitted from the transmission to the final drive to the wheels, and a part of the torque will be stored due to the deformation of the transmission system. in the transmission system. In this case, after the Electronic Parking Brake (EPB) is enabled, entering the P gear of the transmission for parking will cause the torque stored in the vehicle transmission system to be unable to be released. Later, when the transmission exits the P gear, due to the rapid release of the torque in the transmission system, it will cause an impact between the transmission parki...
