Technical Field
The invention relates to the field of vehicle chassis, in particular to an automatic parking device with a memory function and a method.
Background
With the development of economy and the improvement of the living standard of people, automobiles become an important vehicle for people to ride instead of walk, and at present, an electronic parking system (epb) (electrical park brake) is used for a part of vehicles. The electronic parking brake system is a technology that integrates a temporary brake function during driving and a long-term brake function after parking, and realizes parking brake in an electronic control mode.
The electronic hand brake is a technology for realizing parking brake in an electronic control mode. The working principle of the brake is the same as that of a mechanical hand brake, and the brake shoe of the rear wheel is tensioned by a stay cable to brake. The other is to use an electronic mechanical caliper to control the parking brake by clamping the brake pad by the motor,
the electronic hand brake is extended from a basic parking function to an automatic parking function AUTOHO L D (automatic parking). the application of the automatic parking function technology of AUTOHO L D ensures that a driver does not need to brake for a long time when the vehicle stops, and the unnecessary sliding of the vehicle can be avoided under the condition of starting the automatic electronic parking brake, namely the vehicle cannot roll back.
When the AUTOHO L D automatic parking function is used, the automatic parking function is generally required to be turned on by manually operating a switch under the conditions (the closing state of the main driving side door, the fastening state of the main driving side seat belt, and the non-flameout state of the ignition switch) that are satisfied.

The automatic parking function is not started when the detection module does not detect the startup information of the AUTOHO L D switch, which indicates that the AUTOHO L D switch is not pressed down, so the automatic parking function is not started.
Further, the detection module can also receive signals transmitted by an accelerator pedal sensor, and when the detection module detects that an accelerator pedal is pressed down, the automatic parking function is closed. At this time, the vehicle is restarted and the vehicle continues to travel, and therefore the automatic parking function is turned off to allow the vehicle to move forward.
Further, the detection module can also receive signals transmitted by a brake pedal sensor, and when the detection module detects a brake pedal depression signal, the control module applies pressure to the wheel. When the automatic parking function is executed, an execution signal is required, and usually, a brake pedal is deeply depressed under the condition that the automatic parking function is turned on, which indicates that the vehicle needs to be stopped. After obtaining the signal of the depression of the brake pedal, the control module judges that the user needs to stop the vehicle at the moment, and therefore the automatic parking function is executed.
When the automatic parking function is started, a driver presses an AUTOHO L D switch to start the automatic parking function under the conditions that an engine is in a starting state, a main driving door is closed and a main driving side safety belt is fastened, after the driver decelerates the vehicle to a state that the vehicle is completely static, the automatic parking function is started, an Electronic Stability Control (ESC) maintains four-wheel pressure to achieve the purpose of parking, the hydraulic pressure is kept for 10 minutes at most for parking after the driver releases a brake pedal, the hydraulic pressure is withdrawn after 10 minutes, and the EPB (electronic parking system) performs parking.
When one of the conditions of engine starting, main driving door closing and main driving side safety belt fastening is not satisfied, and the automatic parking function exits, the condition is satisfied again, and at the moment, if the detection module detects that the switch starting information of the condition that the driver starts the automatic parking function by pressing the AUTOHO L D switch, the detection module detects the relevant information, the control module can automatically start the automatic parking function.
