Fig. 6 is a timing chart of internal signals of a parking method according to a second embodiment of the present invention, and based on fig. 6, the parking method after adding the first and second shift assist signals may include: and S21, judging whether the brake pedal signal is not pressed down. The brake pedal is special, and when the brake pedal is pressed down, the driver is proved to be in the vehicle. And S22, if the brake pedal signal is not pressed, judging whether the first gear shifting auxiliary signal and the second gear shifting auxiliary signal are both in an opening state, and at the moment, not limiting the sequence of judgment. And respectively judging the states of the first gear shifting auxiliary signal and the second gear shifting auxiliary signal according to the driver side door signal and the driver safety belt state signal in the state signals. And S23, if the first gear shifting auxiliary signal and the second gear shifting auxiliary signal are both in an on state, and the gear signal is determined to be in a non-parking gear and the vehicle speed signal is determined to be that the vehicle speed is less than or equal to the set vehicle speed threshold value, executing a parking operation on the vehicle. And S24, switching the states of the first gear shifting auxiliary signal and the second gear shifting auxiliary signal from an on state to an off state. At this time, if a gear shift request is received, gear shift is performed in response to the gear shift request. And S25, when the driver side door signal is switched from on to off again, and the driver safety belt state signal is switched from off to on again, the parking device in the electronic gear shifting system judges whether each signal in the state signals meets the parking condition next time.
In this embodiment, the first gear shifting auxiliary signal and the second gear shifting auxiliary signal are newly added, the parking operation is executed according to the two signals, and after the automatic parking logic is triggered, the gear shifting request can still be responded, so that the driver does not misunderstand that the system fault is caused, on the premise of ensuring safety, the user operation cannot be excessively interfered to cause the complaint of the user, and meanwhile, the inconvenience for the maintenance operation cannot be caused.
In the embodiment, the state signals of the vehicle are acquired, and comprise gear signals, brake pedal signals, driver safety belt state signals, driver side door signals and vehicle speed signals; determining whether each of the status signals satisfies a parking condition; if not, returning to continuously obtain the state signal of the vehicle; if so, executing parking operation on the vehicle, switching the states of the first gear shifting auxiliary signal and the second gear shifting auxiliary signal from the starting state to the closing state, and if receiving a gear shifting request, responding to the gear shifting request to shift gears. According to the technical scheme of the embodiment, whether a driver leaves the vehicle when the vehicle is in a non-parking state is judged by judging whether each signal in the state signals of the vehicle meets the set parking condition, the judgment condition is more perfect, the judgment logic is more accurate, the parking error is avoided, the parking accuracy and safety are improved, and the user experience is further improved; and through increasing two auxiliary signals of shifting, after the vehicle parking, still can respond to the request of shifting, under the prerequisite of guaranteeing safety, can not excessively interfere user operation and lead to user's complaint, further improved user experience effect.
