Vehicular intelligent brake control method of the present invention can select and formulate multiple brakings according to different drivers
Pattern automatically adjusts braking system parameter, improves braking ability when driving, meets different driving habit demands, carried for driver
For experience of preferably driving a vehicle, driver comfort is improved, ensures traffic safety.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Description of the drawings
Fig. 1 is the present embodiment Vehicular intelligent brake control method flow chart；
Fig. 2 is the present embodiment driver deceleration and occurrence frequency curve graph.
Specific implementation mode
As shown in Figure 1, a kind of Vehicular intelligent brake control method, including：
S101：Identification drives the driver of the vehicle；
S102：Standard braking mode is selected either automatically or manually, or manually selects self study braking mode；
S103：Braking system parameter is adjusted according to the braking mode of selection；
S104：According to the braking system parameter combination real vehicle vehicle condition, brake fluid pressure is established and distributed, the vehicle braking is controlled.
Above-mentioned Vehicular intelligent brake control method, can the different driver of automatic identification, and select and formulate multiple brakings
Pattern automatically adjusts braking system parameter, improves braking ability when driving, meets different driving habit demands, carried for driver
For experience of preferably driving a vehicle, driver comfort is improved, ensures traffic safety.In vehicle travel process, driver can independently select
Meet the braking mode of personal driving habit.When the non-selected self study braking mode of driver, it is defaulted as selection criteria braking
Pattern uses standard brake parameters.When driver's selection meets the self study braking mode of personal driving habit, individual character can be carried out
Change selection, definition, adjust braking system parameter.
S101 when specific operation, generally identifies the driver for driving the vehicle, the specific information can by specific information
To be the combination of one or more of：Such as user's car key, mobile phone associated with automobile, palm PC or driver
The bio-identifications modes such as fingerprint, iris, voice, face figure, the step are mainly used for identifying specific driver, are convenient for postorder
Automatically select braking mode.
In S102, driver can automatically select corresponding standard braking mould according to driver's automatic identification function of S101
Formula can also manually select standard braking mode by human-computer interaction interface or mould braked in self study according to personal driving habit
Formula.The human-computer interaction interface can be that display screen is controlled in vehicle, and mobile phone associated with vehicle, palm PC or voice are known
Not Deng devices, for driver select or formulate driving mode.
The standard braking mode includes sensitive-type braking mode, universal braking mode and slow type braking mode, is divided
Different service brake characteristics is not corresponded to.The sensitive-type braking mode can form braking when input power is smaller, described slow
Slow type braking mode braking builds that pressure is relatively slow, and the universal braking mode is suitble to most of operator brake requirements.It is different
Braking mode can meet different type operator demand.In actual life, different sexes, different age group driver traveling
Braking custom difference is very big, and if the common braking decelerations of Fig. 2 driver A driver than is big, such case, driver can
It can need to match opposite short stroke, the small sensitive-type brake parameters of pedal force（Select sensitive-type braking mode）.Driver B is normal
Smaller than general driver with braking deceleration, longer using relative travel, the brake parameters of bigger pedal force are more suitable（Select
