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 fully automatic parking control method, control system and vehicle. The control method includes: determining the parking mode according to the ramp value of the ramp environment where the vehicle is located; according to the parking mode, to control the vehicle Provide corresponding torque when driving at the target speed in the current gear; detect the parking distance of the vehicle, and switch on or off the power according to the parking distance, so that the vehicle can park at the target speed according to the real-time corrected parking route parking space. The invention can perform automatic parking 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] In the prior art, there are two methods for fully automatic parking control of vehicles: one is to control the engine and the transmission of the torque converter through the body stability system to realize the automatic parking function. Although this control method can achieve different Fully automatic parking applications in different environments on ramps, but due to the structural differences between the torque converter and the dual clutch itself, this solution cannot be used in dual clutch transmissions; Torque reduction function, the transmission itself uses the creep mode method to realize the automatic parking function. This control method has very limited scenarios and can only be applied to flat roads or gentle slopes. [0003] To sum up, due to the comp...
