Problems solved by technology
[0004] 1. The target speed of fully automatic parking is usually lower than 3kmh, and the clutch control is too complicated to allow the body stability system to request control directly
[0005] 2. If the automatic parking function is only realized by the creep mode of the dual clutch itself, it is only suitable for flat roads or gentle slopes, and the application scenarios will have great restrictions
[0006] 3. If the automatic parking function is only realized by the starting mode of the dual clutch itself, it is only suitable for medium and large slopes, but the body stabilization system cannot control the clutch, so it is difficult to ensure a constant target speed
[0007] Therefore, in the prior art, the vehicle body stabilization system is used to control the engine and the dual-clutch gearbox cannot meet the technical requirements, and the use of limited scenarios cannot guarantee the convenience and comfort of automatic parking

The invention discloses a full-automatic parking control method and system and a vehicle. The control method comprises the following steps: determining a parking mode according to a ramp value of a ramp environment where the vehicle is located; according to the parking mode, providing corresponding torque for controlling the vehicle to run at a target vehicle speed at the current gear; and detecting the parking distance of the vehicle, connecting or disconnecting the power according to the parking distance, and parking the vehicle in the target parking space at the target vehicle speed according to the parking route which is corrected in real time. According to the method, full-automatic parking can be carried out at a constant target vehicle speed in different ramp environments.
Description
technical field [0001] The invention relates to the technical field of automatic driving, in particular to a fully automatic parking control method, a control system and a vehicle. Background technique [0002] Under the prior art, there are two ways to carry out automatic parking control for vehicles: one is to realize the automatic parking function by controlling the transmission of the engine and the torque converter through the body stabilization system, although this control method can realize different The application of fully automatic parking in different environments on ramps, but due to the structural differences between the hydraulic torque converter and the dual clutch itself, this solution cannot be used on the dual clutch transmission; the second is to control the engine torque increase, For the torque reduction function, the transmission itself uses the creep mode method to realize the automatic parking function. The scene of this control method is very limite...
