The utility model can completely replace the previous manual handbrake device, so that the automobile parking brake system can achieve full automation and intelligent control, greatly simplifying the driver's driving operation process.

[0004] This automatic control device does not have some reminder functions, and thus cannot well meet actual work needs during application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to provide a vehicle parking reminder system for realizing reminders when the vehicle is parked, which can regulate the vehicle use habits of the driver and passengers and provide protection for the normal use of the vehicle.

[0006] In order to solve the technical problems, the technical solution of the utility model is: a vehicle parking reminder system, including a controller, an instrument, and a handbrake handle, the handbrake handle is hinged on the base, the instrument is communicatively connected with the controller, and is characterized in that a power switch is arranged on the outside of the handbrake handle, the power switch is connected in series with the power circuit, the power circuit is connected with the working unit on the instrument, the power switch is used to touch the pulled handbrake handle to energize the power circuit; a speed sensor for sensing the vehicle speed is communicatively connected with the controller, and the instrument controls the corresponding working unit according to the set speed value.

[0007] The working unit can be a buzzer, a text display window or some graphic display window. It is mainly used to remind the driver in a certain way when the handbrake handle is forgotten after starting the vehicle. The communication connection can be a wired connection or a wireless connection, which can realize the flow of electrical signals between different structures.

[0008] Furthermore, the working unit includes a text display window for displaying text information, and sometimes, in order to ensure the reminder effect, the displayed text information can be presented in a flashing manner.

[0009] Furthermore, the working unit includes a buzzer, which can provide buzzing noise or use language to prompt.

[0010] Furthermore, the base is provided with a plurality of ratchets, which are arranged in the direction of movement of the handbrake handle, and the handbrake handle is movably provided with movable teeth, which are used to be clamped to the ratchets, and a button switch is provided at the outer end of the handbrake handle, which is transmission-connected with the movable teeth, and the button switch causes the movable teeth to be clamped or disengaged from the ratchets. The handbrake system is constructed by adopting this structure, so that when the handbrake handle is pulled up, the position stability of the handbrake handle can be maintained, which is convenient for the stability of the vehicle when parking.

[0011] Furthermore, the power-on switch is a micro switch, which can well adapt to the contact with the handbrake handle and has a fast response speed to the position change of the handbrake handle.

[0012] Compared with the prior art, the utility model has the beneficial effects of using the power switch to reflect the state of the handbrake handle, and combining with the electrical signal of the controller, the position change of the handbrake handle can be reflected on the instrument, especially when the position state of the handbrake handle does not match the current state of the vehicle, the driver and passengers can be reminded by means of sound, light and electricity, so that the driver and passengers can operate the handbrake handle in time, which can well meet the working conditions of the vehicle and reduce the wear of corresponding parts on the vehicle.

[0017] In conjunction with the drawings in the specification, the vehicle parking reminder system is applied to a vehicle to provide a reminder when the vehicle is parked, especially when the vehicle changes from a parking state to a driving state, and can remind the driver and passengers to correct some behaviors that do not meet the specifications.

[0018] The structure of the reminder system includes a controller, an instrument, and a handbrake handle 4.

[0019] The controller is the main driving control system of the vehicle, which is used to control the driving speed of the vehicle.

[0020] A base 1 is provided beside the driving position of the vehicle, and one end side of the handbrake handle 4 is hinged on the base 1. A connecting plate 6 is fixedly connected to the base 1, and the connecting plate 6 is arranged vertically. The outer edge of the connecting plate 6 is adapted to the movement direction of the handbrake handle 4. A plurality of ratchets are processed and formed on the outer edge of the connecting plate 6, and these ratchets are evenly arranged on the outer edge of the connecting plate 6. A movable tooth 3 is movably provided on the handbrake handle 4, and the movable tooth 3 is arranged corresponding to the position of the ratchet. The movable tooth 3 extends in the direction of the ratchet, and the movable tooth 3 is used to be clamped to the ratchet. A button switch 5 is provided at the outer end of the handbrake handle 4, and the button switch 5 is transmission-connected with the movable tooth 3, and the button switch 5 causes the movable tooth 3 to be clamped or disengaged with the ratchet. Under normal circumstances, when the button switch 5 is pressed toward the handbrake handle 4, the movable tooth 3 is disengaged from the ratchet. After the button switch 5 is put down, the outer end of the movable tooth 3 is generally reset and clamped to the ratchet.

[0021] The instrument is provided with a number of working units, which are communicatively connected with the controller. A power switch 2 is provided on the outside of the handbrake handle 4, which is connected in series to the power circuit, and the power circuit is connected to the parking reminder working unit on the instrument to supply power to the parking reminder working unit. The power switch 2 is a micro switch, and the power switch 2 is used to touch the pulled handbrake handle 4 to energize the power circuit. The parking reminder working unit mainly works with light or sound. The parking reminder working unit has an icon display interface for displaying the pulled-up state of the handbrake handle 4; a text display interface for displaying that the handbrake handle 4 is not lowered and the vehicle is traveling at a set speed, and a buzzer alarm sound reminder. Normally, the corresponding icons and texts are set to be displayed in a fixed area of ​​the LCD instrument display interface.

[0022] Figure 3This is the equivalent circuit involved in this reminder system. The speed working unit in the meter used to sense the vehicle speed is connected to the controller in communication. A speed value is preset in the meter program, such as 5KM / H. The meter will control the corresponding working unit according to the set speed value. When the parking brake handle 4 is pulled up, since the power switch K is closed and the power circuit is turned on, the meter controls the display of the parking brake icon on the LCD display interface to remind the user that the parking brake handle 4 has been pulled up. After the vehicle starts to move, if the vehicle's continued driving speed exceeds the set value, the controller gives the meter a speed-based communication signal, and the meter controls the display and flashing of the text reminder interface through the program; at the same time, the buzzer is started, and a buzzing sound is emitted to remind the user that the parking brake handle 4 is in the pulled up state.
