And S204, determining a target characteristic curve of the electronic brake pedal according to the adjusting instruction so that the operation feeling of the electronic brake pedal meets the individual requirements of the user.

In this step, the whole of the first current characteristic curve is shifted to the first upper limit curve or the first lower limit curve by a first preset amplitude according to the whole shift command, so as to determine a first target characteristic curve of the pedal force, wherein the target characteristic curve comprises the first target characteristic curve.

Specifically, as shown in fig. 1, the user may shift the characteristic curve as a whole by clicking the integral adjustment button 123, and click a plus sign to approach the characteristic curve at the upper limit, and click a minus sign to approach the characteristic curve at the lower limit.

Further, after the response characteristic of the brake pedal is adjusted, the method further comprises the following steps:

acquiring an operation instruction input by a user; and determining the control parameters of the brake system according to the operation command and the target characteristic curve. Namely, after the response characteristic of the brake pedal is adjusted by a user to enable the operation feeling of the brake pedal to meet the individual requirement of the user, the electronic brake pedal is used for operating the brake system of the vehicle.

The embodiment provides an electronic brake pedal adjusting method, which includes the steps of obtaining operating characteristic parameters of an electronic brake pedal, determining and outputting a characteristic diagram to be adjusted according to the operating characteristic parameters, then obtaining an adjusting instruction input by a user, editing and adjusting the characteristic diagram to be adjusted according to the adjusting instruction, and then determining a target characteristic curve of the electronic brake pedal according to the adjusting instruction, so that the operating feeling of the electronic brake pedal meets the individual requirements of the user. The technical problem that control parameters of a brake operator cannot be fully adjusted according to self characteristics of a brake operator in the prior art is solved. The automatic adjustment of the operation control parameters of the brake operator is realized according to the personalized characteristics of different operators, and the technical effect of the use experience of the operators is improved.

FIG. 6 is a schematic flow chart of another method for adjusting an electric brake pedal provided in the practice of the present application. As shown in fig. 6, the electronic brake pedal adjusting method includes the specific steps of:

s601, obtaining the operation characteristic parameters of the electronic brake pedal.

And S602, determining and outputting a characteristic diagram to be adjusted according to the operation characteristic parameters.

For steps S601-S602, reference may be made to steps S201-S202, which are not described herein.

And S603, acquiring an adjusting instruction input by a user.

In this step, the adjustment instruction includes a local adjustment instruction. And acquiring a local adjusting instruction input by a user through a preset operation mode. The preset operation mode comprises the following steps: (1) a user clicks a preset adjusting point on a selected characteristic curve, and then dials the adjusting point to move up and down or left and right, or moves the adjusting point through a knob or a button, so that the shape of the characteristic curve near the adjusting point is changed;

(2) and the user double clicks any point on the characteristic curve, sets the point as an adjusting point, and then stirs the adjusting point to adjust the corresponding interval on the characteristic curve.

(3) The user clicks two points on the characteristic curve in sequence, the curve between the two points is set as an adjustment target, and then at least one point on the adjustment target is dragged to change the shape of the curve.

S604, according to at least one adjusting interval corresponding to the local adjusting instruction, at least one curve section of the second current characteristic curve is adjusted in a shifting mode between the second upper limit curve and the second lower limit curve in a fourth preset amplitude.

In this step, the second current characteristic includes: the map of the pedal force versus deceleration and the map of the pedal stroke versus deceleration are, for example, the characteristic maps shown in fig. 3 and 4.

The adjustment interval may be a curve in a certain section of the characteristic curve, or may be the entire characteristic curve.

It should be noted that the user can arbitrarily perform offset adjustment on the characteristic curve between the second upper limit curve (i.e., the upper limit curve) and the second lower limit curve (i.e., the lower limit curve), but when the user's adjustment instruction indicates that the characteristic curve exceeds the range limited by the second upper limit curve and the second lower limit curve, the corresponding maximum or minimum limit value can only be reached.

Further, when the user inputs an adjustment instruction, the adjustment result is synchronously displayed on the vehicle-mounted screen, timing is started after the user stops inputting, and if the adjustment instruction input by the user is not received again within the preset time, the preset evaluation model is started to evaluate the control safety of the brake system corresponding to the adjusted characteristic curve.

For example, if the braking performance is too sensitive (i.e., the calculated braking response sensitivity is greater than a first preset threshold) or too slow (i.e., the calculated braking response sensitivity is less than a second preset threshold) due to the characteristic curve adjusted by the user, a prompt message is sent to the user, or the characteristic curve is automatically optimized to a shape that meets the preset safety performance requirement on the current basis.

And S605, acquiring an operation instruction input by a user.

In the embodiment, after the user finishes adjusting the characteristic parameters of the electrically known pedal, namely, finishes adjusting the pedal feel, the user enters a test driving mode, and in the mode, the running speed of the vehicle is limited within a preset threshold value, such as 30 km/h. So that the user can actually feel and adapt to the change of the brake pedal feel.

And S606, determining control parameters of the brake system according to the operation command and the target characteristic curve.

In this step, after the user operates the brake pedal, the operation intention of the user is fed back according to the adjusted target characteristic curve, and then the corresponding control parameter is generated for the brake system.

For example, if the user adjusts the pedal stroke characteristic curve to shorten the pedal stroke corresponding to the maximum braking force, the brake is performed according to the adjusted pedal stroke.

It should be noted that, in the test driving mode, if the user feels that the pedal feel has been adapted to the adjusted pedal feel, a corresponding confirmation instruction or application instruction may be input, the characteristic parameter corresponding to the pedal feel is determined to be updated, and the test driving mode is ended. If the user feels that further adjustment is needed or reduction is needed, the vehicle needs to be stopped first, and then the corresponding button is clicked on the vehicle-mounted interactive interface for setting.

In this embodiment, the driver may store at least one set of corresponding electronic brake pedal feel control parameters in the vehicle-mounted controller in advance. Other drivers can call the characteristic parameter as an adjustment basis to perform personalized adjustment during debugging. Of course, the control parameters can be automatically switched by using identity recognition means such as face recognition when the sensor detects that the identity of the driver changes.

The embodiment provides an electronic brake pedal adjusting method, which includes the steps of obtaining operating characteristic parameters of an electronic brake pedal, determining and outputting a characteristic diagram to be adjusted according to the operating characteristic parameters, then obtaining an adjusting instruction input by a user, editing and adjusting the characteristic diagram to be adjusted according to the adjusting instruction, and then determining a target characteristic curve of the electronic brake pedal according to the adjusting instruction, so that the operating feeling of the electronic brake pedal meets the individual requirements of the user. The technical problem that control parameters of a brake operator cannot be fully adjusted according to self characteristics of a brake operator in the prior art is solved. The automatic adjustment of the operation control parameters of the brake operator is realized according to the personalized characteristics of different operators, and the technical effect of the use experience of the operators is improved.
