Abstract
The invention belongs to vehicle hand brake system fields, it is related to a kind of vehicle automatic hand braking device and method, including gravity sensor, hand-braking device, control unit, voltage-stablizer and switch, utilize the open state of switch control voltage-stablizer, control the working condition of automatic hand braking device, by control unit judge on pilot set whether someone, send out vehicle brake command to hand-braking device when no one, apply the automatic braking that brake force realizes vehicle to vehicle by hand-braking device.Compared with prior art, the present invention vehicle automatic hand braking device and method can avoid because driver neglect forget to pull the hand brake caused by safety accident problem, after driver gets off, if vehicle parking brake do not have drawing, automatic pull-up parking brake is prevented the generation of severe traffic accidents by vehicle automatic hand braking device.
Description
Technical field
The invention belongs to vehicle hand brake system fields, and in particular to a kind of vehicle automatic hand braking device and method.
Background technology
China's vehicle guaranteeding organic quantity dramatically increases in recent years, and various traffic accidents also emerge one after another.Wherein, because driver dredges
Suddenly, accident caused by not pulling the hand brake the sliding of vehicle oneself when leading to no one on vehicle of getting off often is pacified to the lives and properties of people
Cause serious consequence entirely.Current existing hand brake device is generally mechanical parking brake and electronics parking brake.Mechanical parking brake is purely mechanic dress
It sets, pulls hand brake lever to realize parking by driver, and electronics parking brake has only changed hand brake lever into parking switch, is driven with motor
Power replaces driver's pulling force.Two kinds of hand brake devices must be operated in each parking by driver to be started, Wu Fashi
Existing automatic hand brake function.
Invention content
In view of the above problems, a kind of vehicle automatic hand braking device of present invention proposition and method, to avoid because driving
Member neglects and forgets safety accident problem caused by pulling the hand brake.
To achieve the above object, specific technical solution of the present invention is as follows：A kind of vehicle automatic hand braking device, including gravity pass
Sensor, hand-braking device, control unit, voltage-stablizer and switch, wherein gravity sensor is mounted below pilot set,
It is connected with control unit by data line, for measuring the weight on pilot set；Hand-braking device is used to apply to vehicle
Brake force is bi-directionally connected by data line and control unit；Control unit is used to receive the weight data of gravity sensor, judges
Whether on seat, control unit is additionally operable to read hand-braking device state driver, judges whether to send to hand-braking device
Brake command；The input terminal of voltage-stablizer is connected by cable with on-vehicle battery, and output end passes through cable and gravity sensor, parking brake
Brake, control unit connection, it is vehicle-mounted for providing stable voltage for gravity sensor, hand-braking device and control unit
It is provided with switch between battery and voltage-stablizer, switchs the open state for controlling voltage-stablizer, further control vehicle is automatic
Hand brake device open state.
The present invention also provides a kind of vehicle automatic hand brake methods, include the following steps：
1) initialization weight threshold value G0, in the present embodiment, the weight on seat when no one is demarcated as 0kg, G0It is set as
30kg；
2) by switching unlocking vehicle automatic hand braking device；
3) driver is judged whether on seat, and control unit reads the gravimetric data G that gravity sensor measures, if one
G >=G in a period Δ t0, then judge 3) driver on seat, goes to step, otherwise judge that driver not on seat, turns
Step 4)；
4) hand-braking device state is read, if hand-braking device is open state, goes to step 3), otherwise goes to step 5).
5) hand-braking device is opened, is gone to step 3).
Compared with prior art, the present invention can to avoid because driver neglects forget to pull the hand brake caused by safety accident ask
Topic, after driver gets off, if vehicle parking brake is not drawn, automatic pull-up parking brake is prevented serious traffic by vehicle automatic hand braking device
The generation of accident.
